Product details

Dual 100 A fast recovery diode in a chassis-mount module

The STTH200W04TV1 from STMicroelectronics packs two independent fast recovery diodes rated 100 A average rectified per diode at 400 V reverse voltage, with a 55 ns reverse recovery time. The SOT-227-4 miniBLOC (also designated ISOTOP) chassis-mount package is designed for bolting directly to a heatsink — the exposed metal baseplate conducts heat away from the die, making this a module for high-current PFC stages, output rectifiers in welding inverters, and DC-DC converter secondary-side freewheeling where switching losses matter.

The 400 V DC reverse rating covers single-phase PFC bus voltages with headroom for line transients. The 55 ns trr qualifies as fast recovery under the 500 ns / 200 mA classification.

ST lists the STTH200W04TV1 as obsolete.

Frequently asked questions

Does STTH200W04TV1 come in a surface mount package?

No. The STTH200W04TV1 is a chassis-mount module in an SOT-227-4 miniBLOC (ISOTOP) package. It bolts to a heatsink and has screw terminals — not a surface-mount footprint.
