BZX55C2V4 - BZX55C56 Zener Diodes

Notes:

1. Zener Voltage (V

Z

)

The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T

L

) at 30°C ± 1°C and 3/8” lead length.

2. Maximum Zener Current Ratings (I

ZM

)

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.
