Note: 1.The type numbers listed have zener voltage min/max as shown. Device tolerance of ±2% are indicated by a “B”

instead of a “C”. Zener voltage is measured with the device junction in thermal equilibrium at the lead temperature

of 30℃±1℃.

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) =0.1IZ(dc) with the ac frequency = 1k Hz.

3.This data was calculated using nominal voltages. The maximum current handling capability on a worse case basis is

limited by the actual zener voltage at the operating point and the powered derating curve.
