Product details

600 V, 30 A fast recovery diode for PFC and inverter stages

The STTH31AC06SWL is a 600 V, 30 A general-purpose fast recovery diode from STMicroelectronics, part of the STTH31 family. Its 65 ns reverse recovery time (trr) suits it for continuous-conduction-mode PFC boost stages, output rectification in resonant converters, and freewheeling diodes in motor-drive inverters where switching losses dominate the thermal budget.

The 65 ns trr is specified under standard test conditions for fast-recovery diodes. The 2 V forward drop at 30 A is the conduction-loss floor; at high line and light load the 10 µA reverse leakage at 600 V keeps standby losses negligible.

Junction temperature range and package

The TO-247-3 through-hole package offers a large copper tab for heatsink mounting.

Frequently asked questions

What is the reverse recovery time of STTH31AC06SWL?

The reverse recovery time (trr) is 65 ns, which qualifies it as a fast recovery diode per the industry standard of ≤500 ns at >200 mA.
