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

4. Nominal Zener voltage is meas ured with the device junction in thermal equilibrium at TL = 30 C 1 C

5. ZZT and ZZK are meas ured by dividing the AC voltage drop acros s the device by the ac current applied.

The s pecified limits are for IZ(AC ) = 0.1 IZ(dc) with the AC frequency = 1 K Hz.
