[1] Nominal zener voltage is measured with the device junction in thermal equilibrium at T

L = 30°C ± 1°C.

[2] All part numbers shown indicate a V

Z tolerance of ±5%.

[3] Z

ZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for IZ(AC) = 0.1 IZ(DC), with the AC frequency = 1 kHz.
