Product details

Its 90 ns reverse recovery time puts it in the class of parts used for continuous-conduction-mode (CCM) power factor correction boost stages and high-frequency output rectification in switched-mode supplies — where every nanosecond of recovery loss shows up as heat in the junction.

40 A per diode — thermal budget in a TO-247

Each diode in the pair handles 40 A continuous (average rectified). At 1.55 V forward drop at 30 A, conduction loss runs about 46 W per diode at full tilt — the TO-247-3 package needs a substantial heatsink and forced airflow to keep the junction below the 175 °C maximum. The common-cathode configuration means the two cathodes share the centre pin, which simplifies the PCB layout for a centre-tapped secondary or a dual-boost interleaved PFC.

Frequently asked questions

What is the reverse recovery time of STTH60L06CW?

The reverse recovery time is specified at 90 ns, which qualifies it as a fast recovery diode (≤ 500 ns at > 200 mA). This makes it suitable for high-frequency switching applications like PFC boost stages.
