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℃ and 3/8″ lead length.
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.
