Nominal zener voltage is measured with the device junction in thermal equilibrium at TL = 30°C ± 1°C.
[2]
All part numbers shown indicate a VZ tolerance of ±5%.
[3]
ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for I
Z(AC)
= 0.1 I
, with the AC frequency = 1 kHz.
