The headline number is the 90 ns reverse recovery time — that is the speed that decides whether this part works in your switching supply or motor-drive snubber. At 300 V reverse voltage and 1.2 V forward drop at 100 A, it is built for high-current, high-voltage rectification where you need to keep switching losses under control. ## 100 A per diode — sizing the heatsink Each of the two independent diodes is rated for 100 A average rectified current. That means 200 A total through the package if both legs are conducting, but the thermal limit is the ISOTOP baseplate's ability to sink the heat. The 1.2 V forward drop at 100 A gives about 120 W per diode — that is a serious thermal design exercise. The chassis-mount ISOTOP package expects a bolted-down interface to a heatsink; this is not a part you solder into a PCB. ## 300 V blocking — the rail voltage it handles The 300 V DC reverse voltage rating covers most 240 VAC rectified rails (which peak around 340 V, so leave margin) and 250 VDC bus architectures. The 200 µA reverse leakage at 300 V is typical for a fast-recovery part at this voltage class — expect it to climb with junction temperature, but the datasheet's 150°C max junction gives the headroom for high-ambient environments like motor drives or welding equipment. ST's product status for the STTH20003TV1 is Active. No end-of-life notice, no last-time-buy deadline. If you are replacing a failed unit in an existing board, the same order code drops straight in — same package, same pinout, same thermal interface.","metaTitle":"ST STTH20003TV1 Fast Recovery Diode, 100A, 300V, ISOTOP","metaDescription":"STTH20003TV1 dual fast-recovery diode: 90 ns trr, 100 A per leg, 300 V Vr, ISOTOP chassis-mount.
