Product details

85 ns reverse recovery — what it buys the PFC or boost stage

The STTH810DI is a general-purpose fast recovery diode rated for 1000 V reverse voltage and 8 A average forward current. Its 85 ns reverse recovery time (trr) keeps switching losses low in continuous-conduction-mode PFC stages, flyback snubbers, and boost converters where a standard recovery diode would overheat.

1 kV blocking, 8 A forward — derating for the real load

The 1000 V DC reverse rating gives headroom on a 400 V bus (typical PFC output) for line transients and ringing.

TO-220-2 with insulated tab — mounting and thermal path

The through-hole leads are suited for PCB mounting or point-to-point wiring in power supplies and motor drives.

ROHS3 compliant.

Frequently asked questions

What is the reverse recovery time of the STTH810DI?

The reverse recovery time (trr) is 85 ns, which qualifies it as a fast recovery diode suitable for switching frequencies in the tens of kHz range.

Is the STTH810DI obsolete or end-of-life?

No — the product status is listed as Active.

Is the STTH810DI RoHS compliant?

Yes, it is ROHS3 compliant.
