Product details

50 ns trr — the switching-loss ceiling

The STTH2R06U is a 600 V, 2 A fast recovery rectifier from STMicroelectronics, built for continuous-current switching stages where reverse recovery time sets the turn-off loss. Its 50 ns trr keeps the switching energy low enough for 100 kHz PFC boost stages and flyback snubbers — the diode recovers before the MOSFET's drain voltage rings back, so you don't burn the efficiency margin in the recovery tail.

600 V blocking with 175 °C junction

600 V reverse voltage covers the 400 VDC bus in a 230 VAC PFC stage with 1.5× derating — comfortable margin for line transients. At 2 A forward, the 1.7 V max Vf produces 3.4 W conduction loss; the SMB package's thermal pad on the cathode tab pulls that heat into the board copper.

ROHS3 compliant, no exemption conflicts for EU markets.

Frequently asked questions

Where can I view the STTH2R06U datasheet?

The STTH2R06U datasheet is available from STMicroelectronics' website or through distribution portals. The key parametric table lists the 50 ns trr, 600 V Vr, 2 A Io, 1.7 V Vf at 2 A, and 2 µA leakage at 600 V — all cited in this listing.

How does STTH2R06U compare to STTH2R06?

The STTH2R06 is the same die in a different package variant — the 'U' suffix on STTH2R06U indicates the SMB surface-mount package (DO-214AA), while the base STTH2R06 is typically a through-hole or different outline. The electrical specs (600 V, 2 A, 50 ns trr) are identical; the package is the only difference.

What is the reverse recovery time of STTH2R06U?

The reverse recovery time (trr) is 50 ns, measured at standard test conditions. This is a fast recovery diode — suitable for switching frequencies up to about 100 kHz in continuous-current mode.

Is STTH2R06U RoHS compliant?

Yes, the STTH2R06U is ROHS3 compliant, meeting the EU RoHS directive without exemptions.
