Notes:
1. Zener Voltage (V )
Z
The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T ) at 30C 1C and 3/8 lead length.
L
2. Maximum Zener Current Ratings (I )
ZM
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.
