1) Tested with pulses tp=20 ms.  
2) Valid provided that leads are kept at ambient temperature at a distance of 8 mm form case.  
3)ZENER IMPEDANCE (ZZ) DERIVATION: 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 = 60 Hz.  
4)ZENER VOLTAGE (VZ) MEASUREMENT: Nominal zener voltage is measured with the device junction in thermal equilibrium  
at the lead temperature of 30°C ±1°C and 3/8, lead length.
