VF Forward Voltage = 1.0 V Maximum @ IF = 100 mA for all types
Notes:
1. The type numbers listed have zener voltage min/max limits as shown.
2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage
tolerances, contact your nearest SeCoS 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 (IZT or IZK) is superimposed to IZT or IZK
