VF Forward Voltage = 1.1 V Maxim um @ IF = 200 mA for all types
Notes:
1. The type numbers listed have zener voltage as s hown and have a st andard tolerance on the nominal zener voltage of ±5%.
Suffix A = ±10%, C = ±2% and D = ±1%.
2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter
voltage tol erances, contact your nearest Synsemi represent ative.
3. The zener im pedanc e is derived f rom t he 60-cycl e ac vol tage, whic h result s when an ac c urrent havin g an rm s value equal t o
10% of the dc zener current (IZT or IZK) is superimposed to IZT or IZK.
