About this product
The 1N5625 is a 3 A, 400 V standard avalanche rectifier diode with a sinterglass body. It is used in general power supply rectification and freewheeling circuits, and in other applications that need a robust diode with a moderate reverse voltage rating.

Frequently asked questions
Can I use the 1N5625 to rectify 230 V AC mains?
Its 400 V reverse rating is above the peak of 230 V AC mains (about 325 V), so it can be used in a rectifier. Leave some margin for voltage spikes, and use four diodes in a bridge configuration for full-wave rectification.
How do I identify the cathode of the 1N5625?
The cathode is marked by a band printed near one end of the body. Current flows from anode to cathode when the diode is forward biased, so the band end is the cathode side.
