NOTES:
1. Mounted on 5.0mm2(.013mm thick) land areas.
2. Measured on 8.3ms, single half sine-wave or equivalent square wave, duty cycle = 4 pulses
per minute maximum.
3. ZENER VOLTAGE (Vz) MEASUREMENT Nominal zener voltage is measured with the device
function in thermal equilibrium with ambient temperature at 25 ¢J .
4.ZENER IMPEDANCE (Zz) DERIVATION ZZT and ZZK are measured by dividing the ac voltage drop across
the device by the accurrent applied. The specified limits are for IZ(ac) = 0.1 IZ, (dc) with the ac freqency = 60Hz.
