Product details
Overview
STPSC20065DY from STMicroelectronics is an AEC-Q101-qualified 650 V, 20 A average forward current silicon carbide Schottky diode in TO-220AC package, featuring 1.30 V typical forward voltage at 20 A and -40 °C to +175 °C operating junction temperature. It delivers zero reverse recovery charge, temperature-independent switching, and high surge robustness (90 A, 10 ms sine), making it ideal for automotive and industrial PFC stages under hard-switching conditions.
For engineers reviewing the STPSC20065DY datasheet, STPSC20065DY pinout, STPSC20065DY application, or STPSC20065DY equivalent, key selection criteria include its SiC-based zero-recovery behavior, thermal stability up to 175 °C, low capacitive charge (62 nC at 400 V), and TO-220AC mechanical compatibility with standard heatsink mounting.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-efficiency PFC converters by eliminating reverse recovery losses and associated EMI. Its wide bandgap enables stable 650 V blocking with minimal drift in VF and leakage across temperature.
The device operates without minority-carrier storage, resulting in negligible ringing and predictable turn-off dynamics even at elevated junction temperatures. Its Rth(j-c) of 0.60–0.90 °C/W supports direct conduction cooling in compact power modules and onboard heatsinks.
Key Specifications

| VF (typ.) | 1.30 V at IF = 20 A, Tj = 25 °C - Reduces conduction loss to ~26 W per diode in full-bridge PFC |
| IFSM | 90 A (10 ms sine, Tc = 25 °C) - Withstands inrush and overload transients without degradation |
| Tj range | -40 °C to +175 °C - Supports under-hood automotive deployment and industrial ambient extremes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D20065A | Same 650 V/20 A rating; TO-247-2L package; higher Rth(j-c) (1.0 °C/W typ.) | Requires larger heatsink area due to lower thermal conductivity; not AEC-Q101 qualified | Select when board space allows TO-247 footprint and automotive qualification is unnecessary |
| SS12065B | 650 V/20 A; D²PAK package; VF = 1.45 V (typ.); Rth(j-c) = 0.85 °C/W | Limited to Tj ≤ 150 °C; lacks PPAP capability and automotive test documentation | Prefer for cost-sensitive industrial SMPS where AEC-Q101 and 175 °C operation are not required |
Compared with C3D20065A and SS12065B, STPSC20065DY uniquely combines AEC-Q101 qualification, 175 °C operation, TO-220AC mechanical simplicity, and documented PPAP readiness-making it the only choice for production automotive PFC where thermal robustness and supply-chain traceability are mandatory.

FAQ
What is the maximum recommended mounting torque for the STPSC20065DY TO-220AC package?
The datasheet specifies a recommended torque value of 0.55 N·m and a maximum torque of 0.7 N·m for the TO-220AC package. Exceeding 0.7 N·m risks deforming the lead frame or compromising internal wire bonds, potentially causing premature thermal failure or intermittent contact. Use a calibrated torque screwdriver and verify flatness of the heatsink surface before installation.
Does STPSC20065DY require a gate resistor or snubber network in PFC applications?
No. As a Schottky diode with no minority-carrier storage, STPSC20065DY exhibits no reverse recovery and negligible turn-off ringing. Snubbers are unnecessary in properly laid-out layouts with controlled loop inductance. Gate resistors apply only to MOSFETs/GaN HEMTs-not to this diode-and adding them has no functional impact on its operation.
Can STPSC20065DY be used in parallel configurations for higher current handling?
Yes, but only with careful layout and thermal balancing. The device's positive VF temperature coefficient (VF increases with Tj) provides inherent current sharing. However, mismatched thermal paths or unequal trace lengths will cause current imbalance. Use identical heatsink contact resistance, symmetrical copper pours, and separate Kelvin sensing if closed-loop current balancing is required.
Is the TO-220AC package electrically insulated between tab and leads?
Yes-the TO-220AC variant of STPSC20065DY features an electrically insulated metal tab (cathode), meaning the tab is not internally shorted to either lead. This allows flexible mounting: the tab may be bolted directly to a grounded heatsink while maintaining cathode potential, or isolated via mica washer for floating-cathode topologies such as three-level NPC inverters.
