BZX79 voltage regulator diodes

The BZX79 series is a family of low voltage regulator diode. The diode is made in axial-lead DO-35 glass package.[1] Regulating voltages varies from 2.4V to 75V with a total power dissipation maximum of 500 mW. In some datasheets, the series is labelled as zener diode,[2] but this is not always the case as the series relies on avalanche breakdown for higher voltage.[3]

The BZT52 series is a good surface-mount equivalent for the BZT79 series.

## Applications

Diodes in the BZX79 series are used as voltage references or low-voltage stabilizers.
