The type numbers shown have a standard tolerance of 5% on the nominal Zener voltage. 5. Nominal Zener voltage is measured with the device junction in thermal equilibrium at T = 30C 1C. L 6. Z and Z are measured by dividing the AC voltage drop across the device by the ac current applied. ZT ZK The specified limits are for I = 0.1 I with the AC frequency = 1 kHz.
