Product details

What this 1000 V, 8 A fast recovery diode is for

The STTH810G is a fast recovery rectifier from STMicroelectronics, rated for 1000 V reverse voltage and 8 A average forward current. Its 85 ns reverse recovery time suits it for high-voltage switching power supplies, PFC stages, and flyback converters where recovery losses matter.

The 85 ns reverse recovery time is the headline switching spec. Forward voltage is 2 V at 8 A.

D2PAK — rework and footprint reality

The D2PAK (TO-263) is a surface-mount package with a large exposed tab. It reflows well with a standard profile, but the tab soaks heat — preheat the board from the bottom if you are hand-reworking it. Orientation is marked by the chamfer on the tab side.

For a BOM line that calls this exact diode, the available channel is independent distribution — new-old-stock or surplus lots sourced per RFQ.
