Notes:
1. Zener Voltage (V
Z
)
The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T
L
) at 30°C ± 1°C and 3/8” lead length.
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.
