Type
Number
VF Forward Voltage = 1.0v Maximum @ IF=100mA for all types.
Notes:
1. The type numbers listed have zener voltage min/max limits as shown.
2. The zener impedance is derived from the 60-cycle ac voltage, which results
when an ac current having an rams value equal to 10% of the dc zener current
(IZT or IZK) is superimposed to IZT or IZK.
