+ 5% on the nominal Zener voltage.
NOTE : 3. T he type numbers s hown have a s tandard tolerance of+1 C
4. Nominal Zener voltage is meas ured with the device junction in thermal equilibrium at T L = 30 C5. Z ZT and Z ZK are meas ured by dividing the AC voltage drop acros s the device by the ac current applied.
T he s pecified limits are for I Z(AC ) = 0.1 I Z(dc) with the AC frequency = 1 K Hz.
