VF Forward Voltage = 1.1 V Maximum @ IF = 200 mA for all types
Notes:
1. The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zener voltage of ±5% in
Blue marking,
2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter
voltage tolerances, contact your nearest Liteon Semiconductor Corp. representative.
3. 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
.
