Product details

The STTH15R06FP is a 600 V, 15 A fast-recovery diode from STMicroelectronics, built with standard planar technology. Its headline spec is the 50 ns reverse recovery time (trr), which cuts switching losses in hard-switched topologies like PFC boost stages and secondary-side rectification in SMPS. Junction temperature tops out at 175°C, giving thermal margin for continuous full-load operation in a cramped enclosure.

600 V / 15 A — sizing the diode for the rail

Rated for 600 V reverse voltage and 15 A average rectified current, this diode fits high-voltage bulk supplies, motor drive snubbers, and UPS rectifier stages. The forward drop is 2.9 V at 15 A — that's on the higher side, so conduction loss needs a heatsink calculation at full load. Reverse leakage is 60 µA at 600 V, which is tight enough to keep standby losses low in offline designs.

Frequently asked questions

What is the reverse recovery time (trr) of STTH15R06FP?

The reverse recovery time is 50 ns. That's the time it takes the diode to switch from conducting forward current to blocking reverse voltage — fast enough for 100 kHz+ switching frequencies in PFC and flyback converters.
