STMicroelectronics STPSC10H065GY-TR

Overview

STPSC10H065GY-TR from STMicroelectronics is an AEC-Q101-qualified 650 V, 10 A average forward current silicon carbide Schottky diode in D²PAK package, featuring negligible reverse recovery, temperature-independent switching, and 480 pF junction capacitance at 0 V - engineered for high-efficiency PFC stages in automotive on-board chargers and industrial AC-DC power supplies.

For engineers reviewing the STPSC10H065GY-TR datasheet, STPSC10H065GY-TR pinout, STPSC10H065GY-TR application, or STPSC10H065GY-TR equivalent, key selection criteria include its 175 °C max junction temperature, 1.56 V typical forward voltage at 10 A/25 °C, 90 A non-repetitive surge rating, and ECOPACK®2 compliance for automotive-grade thermal and environmental robustness.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical high-frequency, hard-switching PFC circuits by eliminating reverse recovery charge (Qrr ≈ 0) and minimizing voltage ringing. Its wide bandgap enables stable 650 V blocking with low leakage (<100 µA at 25 °C, <425 µA at 150 °C) and minimal capacitive turn-off behavior across -40 to +175 °C.

The device's thermal design centers on a 1.25–1.5 °C/W junction-to-case resistance and high surge capability (90 A @ 10 ms, 25 °C), supporting transient-heavy operation in boost PFC converters where thermal cycling and reliability under load transients are critical.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STPSC10H065GY-TR supports continuous operation at T_C = 135 °C for its rated 10 A average forward current, per datasheet Table 2. Exceeding this requires derating based on R_th(j-c) = 1.5 °C/W max and thermal interface quality. At T_C = 100 °C, it can sustain ~14 A average current with adequate heatsinking.

Does this diode require a gate driver or external control signal?

No - the STPSC10H065GY-TR is a passive two-terminal Schottky diode with no gate terminal or control interface. It operates solely based on forward bias polarity and voltage magnitude, making it compatible with all standard PFC controller topologies without additional drive circuitry.

Can it be used in parallel configurations for higher current handling?

Yes, but only with careful thermal and layout symmetry: matched PCB copper area, identical trace lengths, and shared heatsink mounting to ensure current sharing within ±10%. The positive temperature coefficient of V_F aids natural balancing, but mismatched thermal resistance will cause current hogging and premature failure.

Is the D²PAK package lead-free and RoHS compliant?

Yes - the STPSC10H065GY-TR uses ECOPACK®2-compliant packaging, which is fully lead-free, halogen-free, and RoHS 2011/65/EU compliant. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and is rated for reflow peak temperatures up to 260 °C.
