Description
The HSSR-7110, HSSR-7111, HSSR-7112, HSSR-711E and
SMD 5962-93140 are single channel power MOSFET
optocouplers, constructed in eight-pin, hermetic, dual-
in-line, ceramic packages. The devices operate exactly
like a solid-state relay.
The products are capable of operation and storage
over the full military temperature range and may be
purchased as a standard product (HSSR-7110), with full
MIL-PRF-38534 Class H testing (HSSR-7111 and HSSR-
7112), with MIL-PRF-38534 Class E testing (Class K with
exceptions) (HSSR-711E) or from the DSCC Standard Mi-
crocircuit Drawing (SMD) 5962-93140. Details of the Class
E program may be found on page 11 of this datasheet.

All devices are manufactured and tested on a MIL-
PRF-38534 certied line and are included in the DSCC
Qualied Manufacturers List, QML-38534 for Hybrid Mi-
crocircuits. Each device contains an AlGaAs light emitting
diode optically coupled to a photovoltaic diode stack
which drives two discrete power MOSFETs. The device
operates as a solid-state replacement for single-pole,
normally open, (1 Form A) relay used for general purpose
switching of signals and loads in high reliability applica-
tions.
The devices feature logic level input control and very low
output on-resistance, making them suitable for both ac
and dc loads. Connection A, as shown in the Functional
Diagram, allows the device to switch either ac or dc loads.
Connection B, with the polarity and pin conguration
as shown, allows the device to switch dc loads only. The
advantage of Connection B is that the on-resistance is
signicantly reduced, and the output current capability
increases by a factor of two.
The devices are convenient replacements for mechanical
and solid state relays where high component reliability
with standard footprint lead conguration is desirable.
Devices may be purchased with a variety of lead bend
and plating options. See Selection Guide table for details.
Standard Microcircuit Drawing (SMD) parts are available
for each package and lead style.
The HSSR-7110, HSSR-7111, HSSR-7112, HSSR-711E and
SMD 5962-93140 are designed to switch loads on 28 Vdc
power systems. They meet 80 V surge and ± 600 V spike
requirements.
CAUTION: Maximum Switching Frequency – Care should be taken during repetitive switching of loads so as not to exceed the
maximum output current, maximum output power dissipation, maximum case temperature, and maximum junction temperature.

Typical Characteristics
All typical values are at TA = 25°C, IF(ON) = 10 mA, VF(OFF) = 0.6 V unless otherwise specied.
Notes:
1. Maximum junction to case thermal resistance for the device is 15°C/W, where case temperature, TC, is measured at the center of the package
bottom.
2. For rating, see Figure 4. The output power PO rating curve is obtained when the part is handling the maximum average output current IO as
shown in Figure 2.
3. During the pulsed RON measurement (IO duration <30 ms), ambient (TA) and case temperature (TC) are equal.
4. Device considered a two terminal device: pins 1 through 4 shorted together and pins 5 through 8 shorted together.
5. This is a momentary withstand test, not an operating condition.
6. For a faster turn-on time, the optional peaking circuit shown in Figure 1 may be implemented.
7. VOS is a function of IF, and is dened between pins 5 and 8, with pin 5 as the reference. VOS must be measured in a stable ambient (free of tem-
perature gradients).
8. Zero-bias capacitance measured between the LED anode and cathode.
9. Standard parts receive 100% testing at 25°C (Subgroups 1 and 9). SMD, Class H and Class E parts receive 100% testing at 25°C, 125°C and -55°C
(Subgroups 1 and 9, 2 and 10, 3 and 11 respectively).
10. Applies to HSSR-7112 and 5962-9314002Hxx devices only.
11. Applies to HSSR-7110, HSSR-7111, HSSR-711E, 5962-9314001Hxx and 5962-9314001Exx devices only.

Applications Information
Thermal Model
The steady state thermal model for the HSSR-7110 is
shown in Figure 21. The thermal resistance values given
in this model can be used to calculate the temperatures
at each node for a given operating condition. The thermal
resistances between the LED and other internal nodes
are very large in comparison with the other terms and
are omitted for simplicity. The components do, however,
interact indirectly through θCA, the case-to-ambient
thermal resistance. All heat generated ows through
θCA, which raises the case temperature TC accordingly.
The value of θCA depends on the conditions of the board
design and is, therefore, determined by the designer.
The maximum value for each output MOSFET junction-
to-case thermal resistance is specied as 15°C/W. The
thermal resistance from FET driver junction-to-case is also
15°C/W. The power dissipation in the FET driver, however,
is negligible in comparison to the MOSFETs.
On-Resistance and Rating Curves
The output on-resistance, RON, specied in this data
sheet, is the resistance measured across the output
contact when a pulsed current signal (IO = 800 mA) is
applied to the output pins. The use of a pulsed signal (≤
30 ms) implies that each junction temperature is equal
to the ambient and case temperatures. The steadystate
resistance, RSS, on the other hand, is the value of the re-
sistance measured across the output contact when a DC
current signal is applied to the output pins for a duration
sucient to reach thermal equilibrium. RSS includes the
eects of the temperature rise of each element in the
thermal model. Rating curves are shown in Figures 2 and
4. Figure 2 species the maximum average output current
allowable for a given ambient temperature. Figure 4
species the output power dissipation allowable for a
given ambient temperature. Above 55°C (for θCA = 80°C/
W) and 107°C (for θCA = 40°C/W), the maximum allowable
output current and power dissipation are related by the
expression RSS = PO(max)/ (IO(max))2 from which RSS can
be calculated. Staying within the safe area assures that
the steady-state junction temperatures remain less than
150°C. As an example, for TA = 95°C and θCA = 80°C/W,
Figure 2 shows that the output current should be limited
to less than 610 mA. A check with Figure 4 shows that
the output power dissipation at TA = 95°C and IO = 610
mA, will be limited to less than 0.35 W. This yields an RSS
of 0.94 Ω.

Design Considerations for Replacement of Electro-Me-
chanical Relays
The HSSR-7110 family can replace electro-mechanical
relays with comparable output voltage and current
ratings. The following design issues need to be consid-
ered in the replacement circuit.
Input Circuit: The drive circuit of the electro-mechani-
cal relay coil needs to be modied so that the average
forward current driving the LED of the HSSR- 7110 does
not exceed 20 mA. A nominal forward drive current of 10
mA is recommended. A recommended drive circuit with
5 volt VCC and CMOS logic gates is shown in Figure 1. If
higher VCC voltages are used, adjust the current limiting
resistor to a nominal LED forward current of 10 mA. One
important consideration to note is that when the LED is
turned o, no more than 0.6 volt forward bias should be
applied across the LED. Even a few microamps of current
may be sucient to turn on the HSSR- 7110, although it
may take a considerable time. The drive circuit should
maintain at least 5 mA of LED current during the ON
condition. If the LED forward current is less than the 5
mA level, it will cause the HSSR-7110 to turn on with a
longer delay. In addition, the power dissipation in the
output power MOSFETs increases, which, in turn, may
violate the power dissipation guidelines and aect the
reliability of the device.
Output Circuit: Unlike electromechanical relays, the
designer should pay careful attention to the output
on-resistance of solid state relays. The previous section,
“On- Resistance and Rating Curves” describes the issues
that need to be considered. In addition, for strictly dc
applications the designer has an advantage using Con-
nection B which has twice the output current rating as
Connection A. Furthermore, for dc-only applications, with
Connection B the on-resistance is considerably less when
compared to Connection A.
Output over-voltage protection is yet another important
design consideration when replacing electro-mechanical
relays with the HSSR-7110. The output power MOSFETs
can be protected using Metal oxide varistors (MOVs)
or TransZorbs against voltage surges that exceed the
90 volt output withstand voltage rating. Examples of
sources of voltage surges are inductive load kickbacks,
lightning strikes, and electro-static voltages that exceed
the specications on this data sheet. For more informa-
tion on output load and protection refer to Application
Note 1047.
