Product details

600 V, 30 A, 50 ns — the fast-recovery workhorse for PFC and SMPS

The STMicroelectronics STTH30S06W is a 600 V, 30 A fast-recovery rectifier diode in a DO-247-2 through-hole package. The 3.6 V forward voltage at 30 A is a consequence of the fast-recovery design — the tradeoff is higher conduction loss for dramatically lower switching loss compared to a standard recovery diode.

Obsolete — plan for a replacement or source surplus

The STTH30S06W carries an official Obsolete product status.

Junction temperature range and deployment context

The 175°C maximum junction gives headroom for high-current operation in a confined enclosure, but the 3.6 V forward drop at 30 A means the thermal design must account for roughly 108 W of conduction loss at full rated current — a substantial heat-sinking requirement through the DO-247-2 package's metal tab.

Frequently asked questions

Is STTH30S06W obsolete?

STMicroelectronics has ended production, and no last-time-buy window remains through the factory channel. Sourcing is through independent distribution for sustainment of existing designs.

What is the reverse recovery time of STTH30S06W?

The reverse recovery time (trr) is 50 ns, placing it in the ultrafast class suitable for high-frequency switching applications like PFC and SMPS output rectification.
