Product details

Forward voltage is specified at 860 mV maximum at 10 A per diode — this is the conduction loss figure you need for the thermal design, not a typical value at low current. The 200 V reverse rating gives headroom for 48 V to 100 V bus rails, including the flyback voltage spikes in an off-line PFC or LLC converter output stage.

175°C junction — the thermal budget that matters

The 175°C Tj max means you can push the diode harder on current without derating as aggressively as a 150°C-rated Schottky, but the reverse leakage at 200 V and high temperature (15 µA at 25°C) will climb exponentially — budget the leakage power in the thermal stack-up.

Frequently asked questions

Is the STPS20200CT suitable for high-temperature operation?

Yes — the junction is rated from -40°C to 175°C, which qualifies it for under-hood automotive and industrial environments where ambient temperatures exceed 85°C.

Can the STPS20200CT replace the STPS20100CT?

The STPS20100CT is a 100 V part; the STPS20200CT is a 200 V part. They share the same TO-220-3 common-cathode footprint, so the STPS20200CT is a drop-in replacement if the circuit can tolerate the higher reverse voltage rating — no pinout change needed.
