Product details

Dual 100A fast recovery diode in SOT-227

The STTH200W03TV1 is a dual fast recovery diode from ST, housing two independent 300 V, 100 A average-rated diodes in a single SOT-227 (miniBLOC / ISOTOP) chassis-mount package. Reverse recovery time is 50 ns, placing it in the fast-recovery class for hard-switching topologies.

A 50 ns reverse recovery time at 100 A forward current means the diode clears stored charge quickly, reducing turn-off losses in high-frequency inverters and welding power supplies. The 1.5 V forward drop at 100 A is a trade-off: lower than an ultrafast silicon diode of similar voltage class, but higher than a Schottky — acceptable when the system needs 300 V blocking.

ST lists the STTH200W03TV1 as obsolete.

Frequently asked questions

What is the replacement for STTH200W03TV1?

No official replacement or cross-reference is published by ST. Any substitute must be qualified against the same SOT-227 footprint, 300 V blocking, 100 A average current per diode, and 50 ns trr. A parametric search on those four axes is the starting point.
