Product details
Overview
STPSC10H065BY-TR from STMicroelectronics is an AEC-Q101-qualified 650 V, 10 A average forward current silicon carbide Schottky diode in DPAK package. It delivers zero reverse recovery charge, temperature-independent switching, and 175 °C maximum junction temperature-enabling high-efficiency PFC stages in on-board chargers and solar boost converters.
For engineers reviewing the STPSC10H065BY-TR datasheet, STPSC10H065BY-TR pinout, STPSC10H065BY-TR application, or STPSC10H065BY-TR equivalent, key selection criteria include reverse leakage at 150 °C (≤425 µA), forward voltage drop (1.7–2.05 V @ 10 A, 150 °C), thermal resistance (1.5 °C/W j-c), capacitive charge (28.5 nC @ 400 V), and surge rating (80 A @ 125 °C, 10 ms).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in hard-switching PFC topologies. Its wide-bandgap construction eliminates minority-carrier storage, resulting in no reverse recovery current and negligible ringing-even under full-load, high-temperature operation.
The device operates with stable VF and IR across -40 °C to +175 °C junction range, and its low Qcj (28.5 nC) and Cj (48 pF @ 400 V) minimize turn-off losses and EMI generation in continuous conduction mode (CCM) boost converters.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10065A-TR | Same 650 V/10 A rating; higher VF (1.8–2.2 V @ 150 °C); Rth(j-c) = 1.7 °C/W | Lower thermal performance limits continuous current in unforced-air OBC designs | Select when footprint compatibility with Cree/Cissoid layouts is required |
| FFSD1065A | 650 V/10 A; lower Qcj (24 nC); tighter VF tolerance (1.55–1.75 V); AEC-Q101 qualified | Better EMI profile in high-density telecom PSUs due to reduced capacitive charge | Prefer for new designs targeting lowest possible switching loss and Class B EMI compliance |
Compared with C3D10065A-TR and FFSD1065A, STPSC10H065BY-TR offers the best balance of thermal resistance (1.5 °C/W), PPAP readiness, and proven field reliability in automotive OBC deployments-making it optimal for volume production where supply chain continuity and qualification documentation are critical.

FAQ
Is STPSC10H065BY-TR suitable for use in non-isolated buck converters?
No. This SiC Schottky diode is optimized for high-voltage, high-frequency boost and PFC topologies-not low-side freewheeling in buck regulators. Its 650 V VRRM and DPAK thermal design target high-blocking, high-temperature applications like OBCs, not 12–48 V step-down conversion where lower-voltage Si diodes offer better cost-performance trade-offs.
What is the recommended PCB layout for thermal performance?
Mount the exposed drain pad directly to ≥200 mm² of 2-oz copper on an internal layer, connected via ≥6 thermal vias (0.3 mm diameter, 0.6 mm pitch) to outer-layer copper pours. Keep anode and cathode traces short and wide (≥2 mm width) to minimize parasitic inductance and ensure Rth(j-c) ≤1.5 °C/W under 140 °C case conditions.
Does this diode require a gate driver or external control signal?
No. As a passive uncontrolled rectifier, STPSC10H065BY-TR conducts when forward-biased and blocks when reverse-biased-no gate drive, timing signals, or control logic is needed. It functions autonomously based on circuit voltage polarity and current direction, unlike actively controlled SiC MOSFETs or hybrid modules.
Can STPSC10H065BY-TR replace a 600 V Si fast recovery diode in existing PFC designs?
Yes-with layout review. Its lower VF and zero Qrr improve efficiency, but the DPAK footprint matches standard TO-252 pads. Verify that the PCB copper pour meets thermal requirements (Rth(j-c) ≤1.5 °C/W), and confirm that snubber networks can be reduced or removed due to eliminated reverse recovery ringing.
