Product details

18 ns trr — the switching-loss ceiling

That 18 ns trr puts it in the class that suits hard-switched power-factor-correction boost stages, flyback output rectifiers, and motor-drive snubber clamps where recovery charge directly drives switching loss.

Forward drop and conduction loss at 8 A

Maximum forward voltage is 3.4 V at 8 A — that is the worst-case conduction loss floor at rated current. The 20 µA reverse leakage at 600 V is typical for a planar structure at 25 °C; leakage doubles roughly every 10 °C rise, so the 175 °C Tjmax is the real limit for high-line standby power.

DPAK footprint and thermal layout

The TO-252-3 (DPAK) package has the cathode tab as the main thermal path.

That means it is a current-production line with no announced last-time-buy or end-of-life.

Frequently asked questions

What is the reverse recovery time of STTH8S06B-TR?

The reverse recovery time is 18 ns, which qualifies it as an ultrafast diode suitable for hard-switched PFC and flyback converters operating above 50 kHz.

What package type is STTH8S06B-TR?

It comes in a DPAK (TO-252-3) surface-mount package, also designated as SC-63. The tab is the cathode connection.

Is STTH8S06B-TR RoHS compliant?

Yes. The part is part of ST's ECOPACK® series, which is RoHS-compliant and halogen-free per ST's green-molding standard.
