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 301. 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.
