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 .

4.ZENER IMPEDANCE (Zz) DERIVATION Z_ZTand Z_ZKare 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_Z, (dc) with the ac freqency = 60Hz.
