Product details

600 V, 30 A fast recovery — the switching diode for PFC and boost stages

It is designed for the output stage of power-factor-correction circuits, boost converters, and high-frequency rectification in switch-mode power supplies and motor drives.

55 ns trr — what it delivers in the switching loop

The 55 ns reverse recovery time keeps switching losses low in continuous-current-mode PFC and hard-switched converters. The 2.4 V forward drop at 30 A is the conduction-loss floor. Reverse leakage is specified at 5 µA at the 600 V blocking voltage, which is the steady-state leakage at 25°C — expect it to rise with junction temperature, but the 175°C maximum Tj gives headroom for thermally aggressive layouts in enclosed power supplies.

Through-hole TO-247-2 — mounting and thermal path

The TO-247-2 package provides a large copper tab for heatsinking and a through-hole mounting that suits point-of-load and chassis-mount assemblies. The isolated case simplifies mounting to a shared heatsink in multi-diode topologies.

Frequently asked questions

What is the reverse recovery time of the STTH30ACS06W?

The reverse recovery time (trr) is 55 ns, which qualifies it as a fast recovery diode (≤500 ns at >200 mA Io).

Is the STTH30ACS06W RoHS compliant?

Yes, the STTH30ACS06W is ROHS3 compliant.

Can the STTH30ACS06W be used in high-frequency applications?

Yes. The 55 ns trr and planar technology make it suitable for hard-switched converters and PFC stages operating in the 50–150 kHz range, where its fast recovery characteristic keeps switching losses manageable.
