Note 1. Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead temperature of +30C 1C and 3/8” lead length.
Note 2. 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 = 60Hz.
