Product details
Overview
STPSC10065GY-TR from STMicroelectronics is an AEC-Q101-qualified 650 V, 10 A average forward current silicon carbide Schottky diode in D²PAK package, designed for high-efficiency PFC stages in automotive and industrial AC/DC converters. It delivers negligible reverse recovery, temperature-independent switching, 1.30 V typical forward voltage at 25 °C, and operates up to 175 °C junction temperature.
For engineers reviewing the STPSC10065GY-TR datasheet, STPSC10065GY-TR pinout, STPSC10065GY-TR application, or STPSC10065GY-TR equivalent, key selection criteria include its zero-recovery behavior, high surge robustness (48 A non-repetitive), low capacitive charge (34 nC at 400 V), and thermal resistance of 1.5 °C/W (max) - all critical for hard-switched boost PFC designs.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in continuous conduction mode (CCM) PFC front-ends. Its wide bandgap enables a 650 V blocking rating with no minority-carrier storage, eliminating reverse recovery losses and associated EMI.
Dynamic performance remains stable across -40 °C to 175 °C: junction capacitance varies from 670 pF (0 V) to 55 pF (400 V), and forward voltage increases only modestly - from 1.30 V (25 °C) to 1.50 V (175 °C) at 10 A - ensuring predictable conduction loss over full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in universal-input (90–265 VAC) PFC stages with sufficient margin against line surges and ringing. |
| IF(AV) | 10 A at TC = 150 °C - Specifies DC current capability under real heatsink conditions, not derated lab test value. |
| VF (typ.) | 1.30 V at 10 A, 25 °C - Directly determines conduction loss: ~13 W per diode at 10 A, enabling high-efficiency (>98%) PFC designs. |
| QCJ | 34 nC at VR = 400 V - Low capacitive charge minimizes turn-off switching loss and reduces gate driver stress in totem-pole configurations. |
| Rth(j-c) (max) | 1.5 °C/W - Defines maximum thermal resistance from junction to case, enabling accurate heatsink sizing for 175 °C Tj operation. |
| IFSM | 48 A (10 ms sinusoidal, TC = 25 °C) - Confirms robustness during inrush and overload transients without bond-wire failure. |
Pinout & Package
STPSC10065GY-TR uses the surface-mount D²PAK (TO-263) package with three terminals: anode, cathode, and exposed thermal pad (electrically connected to cathode). The package supports high-power dissipation via PCB copper area and is compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward current flow | Connected to boost inductor node; must handle full AC line rectified current with minimal parasitic inductance. |
| Cathode (Pin 2) | Output terminal for forward current flow | Connected to PFC output capacitor; electrically tied to exposed thermal pad for low-inductance, low-resistance return path. |
| Exposed Pad | Cathode connection & thermal interface | Requires ≥250 mm² copper pour (2 oz) for Rth(j-a) ≤ 45 °C/W; solder mask opening recommended for optimal thermal transfer. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics applications requiring extended reliability and stress testing. |
| No reverse recovery | Eliminates reverse recovery current spikes and associated EMI, enabling higher switching frequencies without snubbers. |
| Temperature-stable switching | Capacitance and forward voltage shift <15% from -40 °C to 175 °C, simplifying control loop compensation across ambient extremes. |
| High surge capability | Withstands 48 A non-repetitive surge (10 ms), supporting reliable operation during cold-start and brown-out recovery events. |

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 | Same 650 V/10 A rating; 1.55 V VF (typ.) at 10 A, 25 °C; TO-247 package; Rth(j-c) = 1.2 °C/W (typ.) | Higher VF increases conduction loss by ~19%; through-hole mounting limits board-level power density. | Select when mechanical robustness and legacy TO-247 heatsink compatibility outweigh surface-mount density benefits. |
| SS10065A | 650 V/10 A; 1.40 V VF (typ.); D²PAK; Rth(j-c) = 1.6 °C/W (max); AEC-Q101 not claimed | Lacks automotive qualification; slightly higher thermal resistance limits peak power handling in compact layouts. | Acceptable for industrial UPS or lighting where AEC-Q101 is not mandated and 0.1 °C/W Rth margin is acceptable. |
Compared with C3D10065A and SS10065A, STPSC10065GY-TR offers the lowest VF (1.30 V), certified automotive qualification, and optimized D²PAK thermal performance - making it preferred for space-constrained, high-reliability PFC designs where efficiency and qualification are jointly critical.

FAQ
Is STPSC10065GY-TR suitable for synchronous rectification?
No - STPSC10065GY-TR is a unidirectional Schottky diode, not a MOSFET-based synchronous rectifier. It conducts only from anode to cathode and cannot be actively controlled. For synchronous rectification, discrete SiC MOSFETs (e.g., SCT3022AL) or integrated drivers are required.
What is the maximum recommended PCB copper area for the D²PAK thermal pad?
ST recommends ≥250 mm² of 2 oz (70 µm) copper connected to the exposed pad using ≥9 thermal vias (0.3 mm diameter, filled or plated) to achieve Rth(j-a) ≤ 45 °C/W. Larger areas improve thermal performance but yield diminishing returns beyond 400 mm².
Does this diode require a gate resistor or snubber network?
No - unlike silicon IGBTs or MOSFETs, STPSC10065GY-TR has no gate and exhibits no reverse recovery. Snubbers are unnecessary in properly laid-out PFC circuits. However, a small RC snubber (e.g., 10 Ω + 100 pF) may suppress high-frequency ringing caused by layout parasitics.
Can STPSC10065GY-TR replace STPSC10065DY in the same footprint?
No - STPSC10065DY uses TO-220AC (through-hole), while STPSC10065GY-TR uses D²PAK (surface-mount). Footprints, thermal vias, and assembly processes differ fundamentally. Board redesign is required for substitution; electrical specs are identical except for package-related Rth and surge ratings.
