NOTES:
1. Mounted on 5.0mm
2
(.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 .
4.ZENER IMPEDANCE (Zz) DERIVATION Z
ZT
and Z
ZK
are measured by dividing the ac voltage drop across
the device by the accurrent applied. The specified limits are for I
Z(ac)
= 0.1 I
