Nominal zener voltage is measured with the device junction in thermal equilibrium at T = 30°C ± 1°C.
L
All part numbers shown indicate a V tolerance of ±5%.
Z
Z
and Z
are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for I
= 0.1 I
, with the AC frequency = 1 kHz.
