Notes:
1.
No suffix indicates a ±5% tolerance on nominal VZ, C denotes a ±2% tolerance, and D denotes a ±1% tolerance.
2.
Zener voltage (Vz) is measured at TL = 30 °C. Voltage measurement to be performed 90 seconds after application of dc current.
3.
The zener impedance is derived from the 60 Hz ac voltage which results when an ac current having an rms value equal to 10% of the
dc zener current (IZT or IZK).
4.
Vf at 200 mA 1.2 volts maximum and Vf at 1.0 A 1.5 volts maximum.
