Notes:

1. Tolerance and type number designation the type numbers listed indicate a tolerance of ±5%.

2. Zener voltage (VZ) measurement

Nominal Zener voltage is measured with the device junction in thermal equilibrium

with ambient temperature at 25

3. Zener impedance (ZZ) derivation: ZZT and ZZK are measured by dividing the ac voltage

drop across the device by the ac current applied. The specified limits are for

IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
