Zeners 1N4678 - 1N4702
Electrical Characteristics TA=25°C unless otherwise noted
Notes:
1. Zener Voltage (VZ)
The zener voltage is measured with the device junction in the themal equilibrium at the lead temperature (TL) at 30°C ± 1°C and 3/8” lead length.
2. Maximum Zener Current Ratings (IZM)
The maximum current handling capability on a worst case basis is limited by the actual zener voltage at the operation point and the power derating curve.
3. Maximum Voltage Change (∆VZ)
Voltage change is equal to the difference between VZ at 100µA and at 10µA.
Device VZ (Volts) @ IZ = 50µ
