Features, Applications

Symbol PD Parameter Power Dissipation TL 75C, Lead Length = 3/8" Derate above 75C TJ, TSTG Operating and Storage Temperature Range

* These ratings are limiting values above which the serviceability of the diode may be impaired.

Notes: 1. Zener Voltage (VZ) The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (TL) 1C and 3/8" lead length. 2. Maximum Zener Current Ratings (IZM) The maximum current handling capability on a worst case basis is limited by the actual zener voltage at the operation point and the power derating curve. 3. Maximum Voltage Change (VZ) Voltage change is equal to the difference between at 100A and at 10A.
