Notes:

1. Zener Voltage (V ) Measurement

Nominal zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T ) at 30°C ± 1°C and 3/8” lead length.

2. Zener Impedance (Z ) Derivation

and Z are measured by dividing the ac voltage drop across the device by the ac current applied. The specified limits are for I

= 0.1 I

with the ac

Z(dc)

Z(ac)

frequency = 60Hz.

3. Maximum Zener Current Ratings (I

)

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.
