Units with guaranteed limits on all seven parameters are indicated by suffix A for + 10% tolerance and suffix "B for +5%, C for 2% and D for +1%. {2} ZENER VOLTAGE (Vz) AND IMPEDANCE (Zzy & ZzK} Test conditions for Zener voltage and impedance are as follows: Iz is applied 40 + 10 ms prior to reading. Mounting contacts are located 3/8" to 1/2" from the Inside edge of mounting clips to the body of the diode. (Ta = 28C * 3c). {3) SURGE CURRENT (i,} Surge currant is specified as the maximum allowable peak, non-recurrent square-wave current with a pulse width, PW, of 8.3 ma. The data given In Figure 6 may be used to find the maximum surge current for a square wave of any pulse width between 1 ms and 1000 ms by plotting tha {4) (5) 4-52 applicabte points on logarithmic paper. Examples of this, using the 33 V and 200 v zeners, ate shown in Figure 7. Mounting contact located as specified in Note 3. Ma = 25'c 180, VOLTAGE REGULATION (4Vz) Test conditions for valtage regulation ara as fol- lows: Vz measurements are made at 10% and then at 50% of the Iz max value listed in the electncal characteristics table. The test currents are the same for the 6% and 10% toferanca devices. The test current time duration for each Vz mea- surement is 40 + 10 ms. (Ta = 25C +80), Mounting contact located as specified in Note 2. MAXIMUM REGULATOR CURRENT {iz;4) The maximum current shown is based on the maximum voltage of a 5% type unit, therefore, it applies only to the B-suffix device. The actual Iz_4 for any device may not exceed the value of 5 watts divided by the actual Vz of tha device.

Zener Voltage versus Zener Current Vz = 11 thru 75 Volts APPLICATION NOTE Since the actual voltage available from a given zener diode is temperature dependent, it is necessary to deter- mine junction temperature under any set of operating conditions, in order to calculate its value. The following procedure is recommended: Lead Temperature, TL, should be determined from: TL = 9LA Pp + TA 6A is the lead-to-ambient thermal resistance and Pp is the power dissipation. Junction Temperature, Ty, may be found from: Ty = TL + ATJL ATyz is the increase in junction temperature above the lead temperature and may be found from Figure ZENER VOLTAGE versus ZENER CURRENT (Figures 8, 9 and 10) (2, ZENER CURRENT (mA) 1 2 3 4 5 6 7 8 $10 Vz, ZENER VOLTAGE (VOLTS) Figure 8.

ATUL = 8L PD For worst-case design, using expected limits of Iz, lim- its of Pp and the extremes of Ty (ATy) may be estimated. Changes in voltage, Vz, can then be found from: AV = 6yz ATy 6yz, the zener voltage temperature coefficient, is found from Figures 2 and 3. Under high power-pulse operation, the zener voltage will vary with time and may also be affected significantly by the zener resistance. For best regulation, keep current excursions as low as possible. 4-54
