Product details

What this dual-diode is and where it goes

A 40 ns trr at 30 A reduces reverse-recovery charge, lowering switching loss and ringing in hard-switched converters. The 1.75 V forward drop at 30 A is a trade-off for the speed.

Common-cathode pair — board-level fit

The common-cathode configuration shares the centre pin (cathode) between both diodes, so the TO-247-3 package gives you two independent anodes on the outer pins. That matches the topology of a centre-tapped secondary winding or a two-switch forward converter where the cathodes tie to the output rail. The through-hole TO-247 body is large enough to bolt to a heatsink with a screw — plan for a thermal pad or insulator if the heatsink is grounded.

STMicroelectronics lists the STTH60AC06CW as an active product.

Frequently asked questions

What is the reverse recovery time of STTH60AC06CW?

The reverse recovery time (trr) is 40 ns, measured at rated conditions. That qualifies it as an ultrafast recovery diode suitable for hard-switched PFC and output rectification.
