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 25℃
The specified limits are for Iz(AC) = 0.1 Iz(DC) with the AC frequency = 60 Hz
