Product details

650 V / 4 A SiC Schottky — Zero trr in a PowerFlat package

The STPSC4H065DLF is a silicon carbide Schottky diode from STMicroelectronics, rated for 650 V reverse voltage and 4 A average rectified current.

What the zero trr means for your BOM

Because the reverse recovery time is 0 ns, you can run this diode at higher frequencies without the thermal penalty of a silicon part. The forward voltage drop is 1.55 V at 4 A — higher than a comparable silicon Schottky, but the switching loss saving more than compensates above about 50 kHz. The 245 pF capacitance at 0 V is typical for a 4 A SiC die; it does not cause the ringing you would see from a silicon diode's reverse recovery snap-off.

It comes in an 8-PowerVDFN PowerFlat HV package — a surface-mount 8x8 mm exposed-paddle design.

It is part of the ECOPACK®2 series, meaning it is RoHS compliant and halogen-free per ST's material declaration.

Frequently asked questions

What is the closest pin-compatible alternative to STPSC4H065DLF?

No official cross-reference or second-source alternate is recorded for this specific order code. For a similar SiC Schottky in the same package and voltage class, look at other 650 V, 4 A SiC diodes in the PowerFlat HV footprint — but confirm pinout and thermal pad compatibility from each datasheet.
