VF Forward Voltage = 900mV Maximum @ IF = 10 mA for all types
Notes:
1. The zener voltage (VZ) is tested under pulse condition of 15mS. The measured VZ is guaranteed to be within specification with
device junction in thermal equilibrium.
2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%.
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.
4. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter
voltage tolerances, contact your nearest YEASHIN representative.
