Product details
Overview
STPSC12065GY-TR from STMicroelectronics is a 650 V, 12 A silicon carbide (SiC) Schottky power diode in D²PAK package, designed for high-efficiency PFC stages in on-board chargers and industrial AC/DC converters. It delivers zero reverse recovery, temperature-independent switching, 1.30 V typical forward voltage at 12 A, and operates up to 175 °C junction temperature.
For engineers reviewing the STPSC12065GY-TR datasheet, STPSC12065GY-TR pinout, STPSC12065GY-TR application, or STPSC12065GY-TR equivalent, key selection criteria include its AEC-Q101 qualification, 5.38 mm creepage (D²PAK HV variant), 36 nC capacitive charge at 400 V, and robust 53 A repetitive surge rating under hard-switching conditions.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical PFC boost stages where reverse recovery losses dominate efficiency loss. Its wide bandgap enables stable 650 V blocking with negligible reverse recovery current and near-zero turn-off ringing-even at 175 °C junction temperature.
The device's capacitive turn-off behavior-quantified by 36 nC total capacitive charge (QCJ) at 400 V and 60–750 pF junction capacitance-is fully characterized across -40 °C to +175 °C and independent of thermal drift, enabling predictable EMI and loss modeling in high-frequency (>100 kHz) PFC designs.
Key Specifications

| Cj | 60 pF @ 400 V - Junction capacitance determining high-frequency impedance and EMI profile |
| IFRM | 53 A @ δ = 0.1 - Repetitive peak forward current supporting transient overload in automotive OBC startup |
Pinout & Package
STPSC12065GY-TR uses the D²PAK (TO-263) surface-mount package with 3 terminals: Anode (pin 1), Cathode (pin 2), and exposed metal tab (pin 3, electrically connected to cathode). The package features UL94 V0 epoxy, 10.4 mm height, and 9.35 mm × 10.40 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward conduction path | Connected to PFC boost inductor node; must withstand full AC line transients and 650 V DC bus |
| Cathode (Pin 2) | Output terminal for forward conduction path | Connected to DC bus capacitor; carries full output current and defines return path for switching loop |
| Exposed tab (Pin 3) | Cathode connection / thermal interface | Electrically tied to cathode; primary thermal path to PCB copper; requires solder mask opening and thermal via array |
Key Features

| No reverse recovery | Eliminates reverse recovery current and associated switching losses, reducing MOSFET stress and EMI in continuous conduction mode PFC |
| 650 V SiC Schottky structure | Enables higher switching frequencies (>100 kHz) than silicon FRDs while maintaining low conduction loss and thermal stability |
| D²PAK package with 5.38 mm creepage (HV variant) | Supports reinforced insulation in 400 V AC input systems per IEC 60664-1, reducing need for slotting or spacing on PCB |

|---|---|---|---|
| C3D12065A-TR | Same 650 V/12 A rating; 1.45 V VF (typ.) at 12 A; 42 nC QCJ; TO-220-2L package | Higher conduction loss and larger QCJ increase switching loss in >100 kHz PFC; through-hole mounting limits board density | Prefer when legacy TO-220 layout exists and thermal margin allows higher VF |
| SS12065A-TR | 650 V/12 A; 1.35 V VF (typ.); 38 nC QCJ; D²PAK package; no AEC-Q101 qualification | Lacks automotive qualification and has wider VF distribution; not validated for PPAP or temperature cycling | Select for cost-sensitive industrial supplies where AEC-Q101 is unnecessary |

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPSC12065GY-TR supports continuous operation with case temperature up to 145 °C, as specified by its IF(AV) = 12 A rating condition. At higher case temperatures, derating is required per the IFRM curve in Figure 3 of DS11624, and junction temperature must remain ≤175 °C using Rth(j-c) = 1.25 °C/W max.
Does this diode require a gate driver or external control signal?
No. The STPSC12065GY-TR is a passive uncontrolled power diode with no gate terminal. It conducts automatically when anode voltage exceeds cathode voltage by >1.3 V and blocks when reverse biased-no driver, biasing, or timing signals are needed.
Can it replace a silicon fast recovery diode in an existing PFC design?
Yes-direct replacement is feasible in most cases, but layout review is essential: verify adequate cathode copper area for thermal dissipation, confirm no parasitic oscillation due to lower QCJ, and validate snubber values since zero reverse recovery eliminates traditional FRD snubber requirements.
Is the D²PAK package lead-free and RoHS compliant?
Yes. STPSC12065GY-TR is ECOPACK®2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The D²PAK package uses lead-free matte tin plating and halogen-free epoxy, with full compliance documentation available from ST's quality portal.
