Product details
Overview
STPSC12065DY from STMicroelectronics is a 650 V, 12 A silicon carbide (SiC) Schottky power diode in TO-220AC package, designed for high-efficiency PFC stages in on-board chargers and industrial AC/DC converters. It delivers zero reverse recovery, 1.30 V typical forward voltage at 12 A, 650 V guaranteed repetitive peak reverse voltage across -40 °C to +175 °C, and 50 A non-repetitive surge current (10 ms, Tc = 25 °C).
For engineers reviewing the STPSC12065DY datasheet, STPSC12065DY pinout, STPSC12065DY application, or STPSC12065DY equivalent, key selection criteria include temperature-independent switching behavior, high surge robustness, AEC-Q101 qualification, creepage-compliant packaging, and SiC-specific thermal performance metrics under hard-switching PFC conditions.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical PFC boost stages where reverse recovery losses dominate efficiency. Its wide bandgap enables full 650 V blocking with low VF and negligible Qrr-eliminating turn-off ringing and reducing EMI generation without snubbers.
The device operates reliably up to 175 °C junction temperature, with Rth(j-c) of 0.85 °C/W (typ.) and 1.25 °C/W (max.), enabling compact heatsink designs. Reverse leakage remains below 1000 µA at 150 °C and VR = VRRM, supporting stable operation in automotive OBC thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Guaranteed blocking voltage over full -40 °C to +175 °C junction range, enabling single-stage 400 V DC bus PFC designs without derating. |
| IF(AV) | 12 A - Average forward current rating at Tc = 145 °C, defining continuous conduction mode (CCM) PFC output capability. |
| VF (typ.) | 1.30 V @ 12 A, 25 °C - Low conduction loss enabling >98% PFC efficiency at rated load; increases only to 1.50 V at 175 °C. |
| IR (max) | 1000 µA @ 150 °C, VR = VRRM - Minimal leakage preserves efficiency at elevated temperatures, critical for sealed OBC enclosures. |
| QCj | 36 nC @ VR = 400 V - Low capacitive charge reduces switching loss and dv/dt-induced gate stress in GaN/SiC half-bridges. |
| Rth(j-c) | 0.85 °C/W (typ.) - Enables direct mounting to heatsink with minimal thermal interface resistance for compact 3.3–22 kW OBC modules. |
| IFSM | 50 A @ 10 ms sinusoidal, Tc = 25 °C - Withstands inrush and line-dip transients in uncontrolled rectifier front-ends feeding PFC stages. |
Pinout & Package
TO-220AC package: 3-pin through-hole outline with isolated tab (anode), cathode lead, and cathode tab connection. Mounting torque: 0.55 N·m recommended (max 0.70 N·m). Creepage distance not applicable (single-side isolation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Anode) | Anode connection / thermal path | Electrically active anode terminal; requires insulating washer when mounted to grounded heatsink; primary thermal conduction path to heatsink. |
| Lead 1 (Cathode) | Cathode connection | Primary cathode current path; used for PCB trace routing in low-inductance PFC layouts; must be kept short to minimize parasitic inductance. |
| Lead 2 (Cathode) | Cathode connection (redundant) | Secondary cathode lead for enhanced current sharing and mechanical stability; electrically parallel to Lead 1; improves solder joint reliability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and humidity testing-enabling use in production OBCs without additional qualification. |
| No reverse recovery (Qrr ≈ 0) | Eliminates reverse recovery loss and associated EMI, allowing elimination of RC snubbers and reducing MOSFET/GaN FET stress in interleaved PFC topologies. |
| Switching behavior independent of temperature | VF, Cj, and QCj exhibit minimal drift from -40 °C to +175 °C-ensuring consistent PFC timing and efficiency across ambient and junction temperature ranges. |
| High forward surge capability (50 A, 10 ms) | Withstands cold-start inrush and grid transient surges without degradation-critical for unattended EV charging in variable grid conditions. |
| D²PAK HV variant available (STPSC12065G2Y-TR) | 5.38 mm min. anode-to-cathode creepage with top coating meets IEC 60664-1 reinforced insulation requirements for 600 V AC mains isolation in OBC designs. |
Applications
| On-Board Charger (OBC) Boost Stage | Industrial AC/DC Front-End |
|---|---|
Use Scenario: High-frequency (65–150 kHz) interleaved boost PFC in 11 kW EV on-board charger operating from 90–264 V AC input. IC Role / Device Role / Timing Role: SiC Schottky freewheeling diode in boost rectification stage; handles bidirectional current during switching transitions with zero recovery delay.

Use Scenario: 3-phase 400 V AC input PFC module for server PSUs and telecom rectifiers requiring >97% efficiency at full load. IC Role / Device Role / Timing Role: Output rectifier in Vienna rectifier topology; sustains high dv/dt edge rates without oscillation due to absence of minority carrier storage. Use Value: Enables 100 kHz+ operation without snubber networks, cutting EMI filter size by 50% and improving power density to >25 W/in³. |
| Solar Microinverter DC Link | EV Fast-Charging Station Pre-Regulator |
Use Scenario: Single-phase 600 V DC link clamping in string-level microinverters exposed to desert ambient temperatures up to 70 °C. IC Role / Device Role / Timing Role: Clamping diode protecting IGBTs during inductive kickback; conducts only during fault or transient overvoltage 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 |
|---|---|---|---|
| C3D12065A (Wolfspeed) | Same 650 V / 12 A rating; VF = 1.5 V (typ.) at 12 A; Rth(j-c) = 1.0 °C/W (typ.); TO-247-2L package. | Higher VF increases conduction loss by ~15%; TO-247 footprint incompatible with TO-220AC PCB layout; requires rework of thermal pad and mounting hole pattern. | Select when higher surge rating (60 A IFSM) is prioritized over board space and thermal resistance; verify heatsink interface compatibility. |
| SS12065A (UnitedSiC) | 650 V / 12 A; VF = 1.45 V (typ.) at 12 A; Rth(j-c) = 0.95 °C/W; D²PAK-7L package; no AEC-Q101 qualification. | Lacks automotive qualification; D²PAK-7L has different pinout and thermal pad geometry; lower creepage (3.48 mm) limits use in reinforced insulation designs. | Acceptable for industrial AC/DC where AEC-Q101 is not required; avoid in OBCs requiring PPAP documentation or IEC 60664-1 creepage compliance. |
Compared with C3D12065A and SS12065A, STPSC12065DY offers the lowest VF (1.30 V), best thermal resistance (0.85 °C/W), and only TO-220AC option qualified to AEC-Q101 with PPAP support-making it the preferred choice for automotive OBCs where thermal density, efficiency, and qualification rigor are jointly constrained.

FAQ
Is STPSC12065DY pin-compatible with standard silicon fast recovery diodes in TO-220AC packages?
No. While the TO-220AC outline matches mechanically, STPSC12065DY uses an anode-tab configuration (tab = anode), whereas most silicon FRDs use cathode-tab. Swapping without PCB revision risks reverse polarity and catastrophic failure. Verify tab polarity before replacement.
What is the maximum allowable case temperature for continuous 12 A operation?
Per datasheet Table 1, IF(AV) = 12 A is rated at Tc = 145 °C. Exceeding this case temperature reduces safe operating current linearly per the derating curve in Figure 3. At Tc = 160 °C, max IF(AV) drops to ~9.5 A to maintain Tj ≤ 175 °C.
Does STPSC12065DY require a gate driver or external control circuitry?
No. As a passive Schottky diode, it requires no gate drive, biasing, or control signals. It operates solely based on applied voltage polarity and magnitude-conducting when anode voltage exceeds cathode by >VF, blocking otherwise. No auxiliary circuitry is needed.
Can STPSC12065DY be used in synchronous rectification topologies?
No. Synchronous rectification requires actively controlled MOSFETs with precise gate timing. STPSC12065DY is a unidirectional, passive rectifier. Its zero-recovery behavior makes it ideal as a freewheeling or boost diode-but it cannot replace SR MOSFETs in LLC or flyback secondary-side regulation.
