DESCRIPTION APPEARANCE
The 1N5913-5956B series of 1.5 watt Zeners provides voltage regulation in a
selection from 3.3 to 200 volts with different tolerances as identified by suffix
letter on the part. These plastic encapsulated Zeners have moisture
classification of Level 1 with no dry pack required. They are also available in
various military screening levels by adding a prefix identifier as described in
the Features below. The plastic molded Zeners with a P suffix provide a
lower thermal resistance (junction to lead) compared to the optional glass
body (G suffix) for these same JEDEC part numbers. Both package options
are available by Microsemi. Microsemi also offers numerous other Zener
products to meet higher or lower power and test-current applications.

NOTES:
1. No suffix indicates a +/-20% tolerance on nominal VZ. Suffix A denotes a +/-10% tolerance, B denotes a +/-5% tolerance, C denotes a
2% tolerance, and D denotes a +/-1% tolerance. Also add a P suffix for plastic construction, e.g. 1N5956BP (G suffix designates glass
body options described by separate data sheet).
2. Zener voltage (VZ) is measured at TL = 30oC and 90 seconds after application of dc current.
3. The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the
dc zener current (IZT or IZK) is superimposed on IZT or IZK. See MicroNote 202 for zener impedance variation with different operating
currents.
