Product details
Overview
STPSC10H12G2Y-TR from STMicroelectronics is a 10 A, 1200 V silicon carbide (SiC) Schottky power diode in D²PAK HV package, designed for high-efficiency PFC, on-board chargers (OBC), and DC/DC converters in electric vehicles. It delivers zero reverse recovery, temperature-independent switching, 1.35 V typical forward voltage at 10 A and 25 °C, and 5.38 mm minimum anode-to-cathode creepage distance per IEC 60664-1.
For engineers reviewing the STPSC10H12G2Y-TR datasheet, STPSC10H12G2Y-TR pinout, STPSC10H12G2Y-TR application in OBC or PFC, or STPSC10H12G2Y-TR equivalent SiC diodes, this page provides verified electrical parameters, thermal resistance (Rth(j-c) = 0.65 °C/W typ.), surge rating (IFSM = 71 A @ 10 ms), and packaging details for hard-switching EV power systems.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-voltage, high-frequency AC/DC and DC/DC stages. Its wide bandgap enables full 1200 V blocking with negligible reverse recovery charge (QCj = 57 nC @ 800 V) and low junction capacitance (Cj = 47 pF @ 800 V).
The D²PAK HV package supports high creepage (5.38 mm anode–cathode) and thermal performance (Rth(j-c) = 0.65 °C/W typ.), enabling operation up to 175 °C junction temperature while maintaining stable VF and IR across -40 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Enables direct use in 800 V battery systems with >50% voltage margin for transients. |
| IF(AV) | 10 A - Rated average forward current at Tc = 155 °C, suitable for continuous conduction mode PFC. |
| VF (typ.) | 1.35 V @ 10 A, 25 °C - Low conduction loss; contributes to <1.5% system efficiency gain vs. Si FRD in 100 kHz PFC. |
| IR (max) | 400 µA @ 150 °C, VR = VRRM - Minimal leakage ensures stable high-temperature blocking in OBC ambient. |
| QCj | 57 nC @ VR = 800 V - Near-zero reverse recovery charge eliminates turn-off ringing and EMI in hard-switched totem-pole PFC. |
| Rth(j-c) | 0.65 °C/W (typ.) - Enables 38 A peak forward current (IFRM) with <10 K rise above case at rated thermal interface. |
| CdA-K | 5.38 mm min. - Meets reinforced insulation requirements per IEC 60664-1 for EV traction auxiliary supplies. |
Pinout & Package
Housed in D²PAK HV (TO-263-2HV) package: surface-mount, isolated tab, epoxy body meeting UL94 V0, with 15.3–15.8 mm length, 9.15–9.35 mm width, and 4.3–4.7 mm height. Anode and cathode terminals are on opposite sides of the molded body to maximize creepage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | High-side power input terminal | Electrically connected to metal tab; requires insulated mounting for floating high-voltage node applications. |
| Cathode (Lead) | Low-side power output terminal | Single Gull-wing lead; carries full load current and must be routed with low-inductance layout for SiC switching integrity. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery | Zero Qrr enables elimination of snubbers and reduces EMI filter size in 100+ kHz PFC designs. |
| Temperature-stable switching | VF and Cj variation <±10% from -40 °C to 175 °C - simplifies thermal derating in under-hood OBC modules. |
| D²PAK HV creepage | 5.38 mm (anode–cathode, coated) - satisfies reinforced insulation for 1200 V DC bus isolation in automotive Grade 2 systems. |
| AEC-Q101 qualified | Validated for automotive power electronics per stress test conditions including HTGB, H3TRB, and temperature cycling. |
| High surge capability | 71 A non-repetitive surge (10 ms sine) - withstands inrush currents during cold-start OBC activation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10120H | Same 10 A / 1200 V rating; Rth(j-c) = 0.75 °C/W (higher); VF = 1.5 V (typ.) at 10 A. | Higher VF increases conduction loss by ~11% in continuous PFC; requires larger heatsink area. | Prefer when legacy layout uses C3D footprint and thermal margin exists. |
| SS12120 | 1200 V / 10 A; VF = 1.45 V (typ.); Qcj = 62 nC; not AEC-Q101 qualified. | Lacks automotive qualification and has higher capacitive charge - unsuitable for OBC PPAP programs. | Select only for industrial solar or UPS where automotive compliance is not required. |
Compared with C3D10120H and SS12120, STPSC10H12G2Y-TR offers the lowest VF (1.35 V), best thermal resistance (0.65 °C/W), and full AEC-Q101 qualification - making it the preferred choice for production EV power systems requiring PPAP documentation and IEC 60664-1 creepage compliance.

FAQ
Is STPSC10H12G2Y-TR pin-compatible with standard D²PAK (TO-263) packages?
No - it uses the D²PAK HV variant, which features extended creepage (5.38 mm anode–cathode) and modified mold compound. Mechanical dimensions differ: L = 15.3–15.8 mm (vs. 10.16 mm standard), and creepage-critical spacing requires updated PCB footprints and isolation slots per IEC 60664-1.
What is the maximum recommended case temperature for continuous 10 A operation?
The datasheet specifies IF(AV) = 10 A at Tc = 155 °C with δ = 0.5 square wave. For continuous DC operation, derate to ≤145 °C case temperature to maintain safe junction temperature (Tj ≤ 175 °C) given Rth(j-c) = 0.65 °C/W and conduction losses ≈14 W at 10 A.
Does this diode require a negative gate drive or external snubber circuit?
Neither - as a Schottky diode, it has no gate and exhibits no reverse recovery. Snubbers are unnecessary due to zero Qrr and low Cj (47 pF @ 800 V). Layout best practice is low-inductance cathode routing and isolated anode mounting to preserve creepage integrity.
Can STPSC10H12G2Y-TR be used in bidirectional switch applications?
No - it is a unidirectional Schottky diode. While it conducts forward current efficiently, it cannot block forward voltage in reverse polarity nor be actively controlled like a MOSFET or IGBT. For bidirectional power flow, pair with a complementary SiC MOSFET in active rectification topology.
