Product details
Overview
STPSC12065G2Y-TR from STMicroelectronics is a 650 V, 12 A silicon carbide (SiC) Schottky power diode in D²PAK HV 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 STPSC12065G2Y-TR datasheet, STPSC12065G2Y-TR pinout, STPSC12065G2Y-TR application, or STPSC12065G2Y-TR equivalent, key selection criteria include its 5.38 mm anode-to-cathode creepage distance, 650 V VRRM guaranteed across -40 °C to +175 °C, and suitability for hard-switching PFC topologies requiring low EMI and high thermal robustness.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical high-frequency, high-voltage rectification roles. Its wide-bandgap construction eliminates minority-carrier storage, resulting in no reverse recovery charge (Qrr ≈ 0) and negligible turn-off ringing - confirmed by measured Qcj = 36 nC at VR = 400 V and Cj = 60 pF at same bias.
The device is optimized for continuous conduction mode (CCM) and transition mode (TM) PFC circuits where thermal stability and surge immunity are essential. With Rth(j-c) = 0.85 °C/W (typ), 50 A non-repetitive surge rating at 25 °C, and AEC-Q101 qualification, it supports automotive-grade OBC designs operating under harsh thermal transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - guarantees blocking capability across full -40 °C to +175 °C junction range, enabling reliable operation in unregulated DC-link environments |
| IF(AV) | 12 A at Tc = 145 °C - defines continuous DC current handling with standard heatsinking in TO-220AC/D²PAK footprint-compatible layouts |
| VF (typ) | 1.30 V at IF = 12 A, Tj = 25 °C - sets baseline conduction loss; increases only to 1.50 V at 175 °C, ensuring stable efficiency over temperature |
| Qcj | 36 nC at VR = 400 V - quantifies capacitive turn-off charge driving EMI and snubber losses; independent of temperature due to Schottky physics |
| Rth(j-c) | 0.85 °C/W (typ) - enables direct thermal path to heatsink; supports >10 W dissipation before reaching 175 °C max junction temperature |
| CdA-K | 5.38 mm (min, with top coating) - meets IEC 60664-1 reinforced insulation requirements for 650 V systems in EV on-board chargers |
Pinout & Package
The STPSC12065G2Y-TR uses the D²PAK HV (High Voltage) surface-mount package, featuring extended creepage distance between anode and cathode terminals and optimized thermal pad layout for PCB conduction cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | High-side input terminal | Electrically connected to exposed metal tab; must be isolated from chassis ground per IEC 60664-1; primary thermal path to PCB copper |
| Cathode 1 (K1) | Low-side output terminal | Left-side lead; used with K2 for parallel cathode routing in high-current PFC layouts |
| Cathode 2 (K2) | Low-side output terminal | Right-side lead; provides dual-cathode configuration to reduce trace inductance and improve current sharing in multi-phase PFC |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery (Qrr ≈ 0) | Eliminates switching losses and voltage overshoot during diode turn-off, reducing snubber component count and EMI filter size |
| AEC-Q101 qualified | Validated for automotive power electronics including on-board chargers, supporting PPAP documentation and long-term reliability under thermal cycling |
| D²PAK HV creepage ≥5.38 mm | Enables 650 V system-level reinforced insulation without additional isolation barriers or potting, simplifying OBC mechanical design |
| 175 °C max junction temperature | Allows operation in compact, thermally constrained enclosures without derating; supports higher power density than 150 °C silicon alternatives |
| High surge capability (50 A, 10 ms) | Withstands line surges and inrush currents in AC/DC front-ends without failure, improving system-level robustness in industrial and EV 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 |
|---|---|---|---|
| C3D12065A-TR | Same 650 V/12 A rating; 1.45 V VF (typ) at 12 A; TO-263-2L (standard D²PAK) package; no HV creepage enhancement | Lacks 5.38 mm creepage; requires external isolation for 650 V reinforced insulation compliance | Select when space-constrained PCB layout prioritizes standard D²PAK footprint over safety-critical creepage margin |
| UJ3D12065K3 | 650 V/12 A; 1.55 V VF (typ); DFN8 8x8 mm package; Rth(j-c) = 1.0 °C/W; not AEC-Q101 qualified | Higher VF increases conduction loss; lower thermal performance limits power density; no automotive qualification | Select for cost-sensitive industrial SMPS where AEC-Q101 and ultra-low VF are non-mandatory |

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPSC12065G2Y-TR is rated for IF(AV) = 12 A at Tc = 145 °C, with absolute maximum junction temperature of 175 °C. Using the typical Rth(j-c) of 0.85 °C/W, the maximum sustainable case temperature under full 12 A DC load is approximately 145 °C - verified by thermal testing in the DS11624 datasheet Figure 3 and Table 1.
Does this diode require a gate resistor or snubber network?
No. As a Schottky diode with negligible reverse recovery charge (Qrr ≈ 0) and low junction capacitance (Cj = 60 pF at 400 V), the STPSC12065G2Y-TR does not generate voltage spikes or ringing during turn-off. ST's application notes confirm snubber networks are unnecessary in properly laid-out PFC circuits using this device.
How does the D²PAK HV package differ from standard D²PAK in layout?
The D²PAK HV variant features extended leadframe spacing between anode (tab) and cathode pins, achieving 5.38 mm minimum creepage with top coating. Its footprint (Figure 13) requires wider isolation gaps on PCB - specifically 15.95 mm length and 7.46 mm width - versus standard D²PAK's ~10 mm × 9 mm outline, per DS11624 page 11.
Is this part suitable for bidirectional operation in V2G applications?
No. The STPSC12065G2Y-TR is a unidirectional Schottky diode with anode and cathode terminals. It conducts only from anode to cathode and blocks reverse voltage up to 650 V. Bidirectional current flow in vehicle-to-grid (V2G) requires actively controlled switches (e.g., SiC MOSFETs) or back-to-back diode configurations - not supported by this single-diode device.
