Notes:
1. The Zener Voltage (V
Z
) is tested under pulse condition of 1ms.
2. The device numbers listed have a standard tolerance on the nominal zener voltage of
±5%.
3. For detailed information on price, availability and delivery of nominal 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 an rms value
equal to 10% of the DC zener current (I
ZT
or
I
ZK
) is superimposed to
I
ZT
or
I
ZK
.
