NOTE :

3. The type numbers shown have a standard tolerance of 5% on the nominal Zener voltage.

4. Nominal Zener voltage is measured with the device junction in thermal equilibrium at T = 30 C 1 C

5. Z and Z are measured by dividing the AC voltage drop across the device by the ac current applied.

The specified limits are for I

= 0.1 I

with the AC frequency = 1 KHz.
