Product details
Overview
STPSC20065GY-TR from STMicroelectronics is an automotive-grade 650 V, 20 A silicon carbide Schottky diode in D²PAK package, qualified to AEC-Q101, with typ. 1.30 V forward voltage at 20 A and junction temperature range of –40 °C to +175 °C. It delivers zero reverse recovery charge, temperature-independent switching, and high surge robustness (70 A IFSM at Tc = 125 °C), making it ideal for high-efficiency PFC stages in on-board chargers and industrial AC-DC supplies.
For engineers reviewing the STPSC20065GY-TR datasheet, STPSC20065GY-TR pinout, STPSC20065GY-TR application, or STPSC20065GY-TR equivalent, key selection criteria include its SiC-based zero-recovery behavior, thermal stability up to 175 °C junction, low capacitive charge (62 nC at 400 V), and D²PAK package suitability for automated SMT assembly in high-power density designs.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in hard-switching PFC topologies by eliminating reverse recovery losses and associated EMI. Its wide bandgap enables stable 650 V blocking with minimal drift in VF and IR across –40 °C to +175 °C.
The device operates with negligible ringing due to absence of minority carrier storage, and its junction-to-case thermal resistance (0.60–0.90 °C/W) supports high power dissipation when mounted on copper-clad PCBs or heatsinks. Dynamic capacitance drops from 1250 pF at 0 V to 100 pF at 400 V, enabling predictable snubber design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in 400 V AC input PFC stages with 1.6× safety margin against line surges. |
| IF(AV) | 20 A at Tc = 140 °C - Supports continuous conduction mode (CCM) PFC operation up to ~2 kW with appropriate heatsinking. |
| VF (typ.) | 1.30 V at IF = 20 A, Tj = 25 °C - Reduces conduction loss vs. Si diodes (~0.5 V lower than 650 V Si FRD), improving efficiency by ~0.3–0.5% in 3.3 kW PFC. |
| Tj Range | –40 °C to +175 °C - Allows placement near hot components (e.g., MOSFETs) without derating in automotive under-hood environments. |
| QCj | 62 nC at VR = 400 V - Low capacitive turn-off charge minimizes switching loss and dv/dt-induced gate oscillation in GaN/SiC half-bridges. |
| Rth(j-c) | 0.60–0.90 °C/W - Enables thermal design with <10 °C rise at 20 A conduction loss (P ≈ 26 W), compatible with standard D²PAK PCB copper areas. |
| IFSM | 70 A (tp = 10 ms, Tc = 125 °C) - Withstands inrush currents during cold-start in EV charging systems without degradation. |
Pinout & Package
The STPSC20065GY-TR is housed in a surface-mount D²PAK (TO-263) package with 3 terminals: Anode (A), Cathode (K), and exposed metal tab (electrically connected to cathode). The package features gull-wing leads, 2.54 mm lead pitch, and a 15.85 mm maximum height per JEDEC MS-013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | AC-side connection in boost PFC | Receives rectified AC input; must be routed with low-inductance trace to minimize voltage overshoot during diode turn-on. |
| Cathode (Pin 2) | DC-link output node | Connects to boost inductor output and high-side switch drain; serves as primary heat path via exposed tab soldered to large copper pour. |
| Exposed Tab | Cathode potential / thermal interface | Electrically tied to cathode; requires full-solder coverage to inner-layer copper for optimal Rth(j-a); no isolation needed. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including OBC, DC-DC converters, and traction inverters requiring long-term reliability at 175 °C. |
| No reverse recovery charge | Eliminates reverse recovery current spikes and associated EMI, enabling higher switching frequencies (>100 kHz) without snubber circuits. |
| Temperature-stable switching | VF increases only ~0.15 V from 25 °C to 175 °C; IR remains <2 µA at 600 V and 175 °C - simplifies thermal compensation in control loops. |
| High surge capability | 70 A non-repetitive surge at 125 °C case temperature ensures robustness during grid transients and cold-start inductance saturation events. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy meets UL 94 V-0 flammability rating - satisfies Tier-1 automotive and industrial environmental mandates. |
Applications
| On-Board Charger (OBC) PFC Stage | Industrial 3.3 kW Server PSU |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D02065E (Wolfspeed) | Same 650 V/20 A rating, but TO-247-2L package; VF = 1.5 V (typ.) at 20 A; Rth(j-c) = 0.75 °C/W. | Requires through-hole assembly and larger footprint; less suitable for ultra-thin OBC modules. | Prefer for legacy TO-247 layouts or where higher surge margin (100 A IFSM) justifies manual assembly. |
| SS12065 (ON Semiconductor) | D²PAK package, but rated 650 V/12 A; VF = 1.45 V (typ.) at 12 A; Tj max = 175 °C; not AEC-Q101 qualified. | Limited to ≤1.5 kW PFC; lacks automotive qualification and thermal headroom for sustained 20 A operation. | Select only for cost-sensitive industrial SMPS where AEC-Q101 and full 20 A rating are not required. |
Compared with C3D02065E and SS12065, STPSC20065GY-TR uniquely combines AEC-Q101 qualification, D²PAK SMT compatibility, and 20 A/175 °C continuous rating-making it the only choice for automotive OBCs requiring automated manufacturing and extended thermal margin.

FAQ
What is the maximum recommended mounting torque for the STPSC20065GY-TR D²PAK package?
The D²PAK package does not require mechanical mounting torque like TO-220AC or DO-247. Instead, reliable thermal and electrical performance depends on full-solder coverage of the exposed cathode tab to ≥2 oz copper with ≥20 mm² thermal pad area. Reflow profile must follow IPC-J-STD-020 for moisture sensitivity level 1.
Does STPSC20065GY-TR require a gate driver or external control signal?
No. As a passive uncontrolled Schottky diode, STPSC20065GY-TR conducts when anode voltage exceeds cathode voltage by >VF and blocks when reverse biased. It has no gate terminal and requires no drive circuitry-unlike SiC MOSFETs or IGBTs which need active gate control.
Can STPSC20065GY-TR replace a 650 V silicon fast recovery diode in an existing PFC design?
Yes, with layout and thermal review. Key changes include reducing snubber size (due to zero recovery), verifying PCB copper area for thermal dissipation (Rth(j-c) differs), and confirming that the 1.30 V VF does not shift control loop compensation. No gate drive or timing adjustments are needed since conduction is self-commutated.
Is the D²PAK variant STPSC20065GY-TR pin-compatible with the TO-220AC STPSC20065DY?
No. While both share identical electrical specifications, the D²PAK (STPSC20065GY-TR) uses gull-wing surface-mount leads with 2.54 mm pitch and integrated cathode tab, whereas the TO-220AC (STPSC20065DY) has through-hole leads and a separate mounting hole. Footprint, reflow profile, and thermal interface design are fundamentally different.
