Taiwan Semiconductor
Notes:
1. The zener voltage (V
Z
) is tested under pulse condition of 30ms.
2. The device numbers listed have a standard tolerance on the normal zener voltage of ±5%.
3. For detailed information on price, availability and delivery of normal zener voltages between the voltages
shown and tighter voltage tolerances, contact your nearest Taiwan Semiconductor representative.
4. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current
having a rms value equal to 10% of the DC zener current(I
ZT
or I
ZK
) is superimposed to I
ZT
or I
ZK
.
