Product details
Overview
STPSC10H12G-TR from STMicroelectronics is a 1200 V, 10 A silicon carbide Schottky power rectifier in D²PAK package, featuring negligible reverse recovery, 1.35 V typical forward voltage at 10 A and -40 °C to +175 °C operating junction temperature. It is designed for high-efficiency PFC stages and secondary-side rectification in industrial SMPS and solar inverters.
For engineers reviewing the STPSC10H12G-TR datasheet, STPSC10H12G-TR pinout, STPSC10H12G-TR application, or STPSC10H12G-TR equivalent, key selection criteria include its zero-recovery switching behavior, temperature-independent capacitive turn-off, low thermal resistance (0.65 °C/W typ.), and ECOPACK®2 compliance for high-reliability power conversion designs.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery and ultrafast diodes in hard-switching topologies. Its wide band-gap material enables stable 1200 V blocking with low VF and near-zero Qrr - eliminating reverse recovery losses and associated EMI.
The device exhibits minimal variation in VF (1.35 V @ 25 °C → 1.75 V @ 150 °C) and IR (60 µA @ 25 °C → 30–400 µA @ 150 °C), ensuring predictable conduction and leakage across full temperature range. Junction-to-case thermal resistance is 0.65 °C/W (typ.) in D²PAK, supporting high-power density layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Enables direct use in 800 V DC-link systems with 50 % safety margin against transients. |
| IF(AV) | 10 A - Rated average forward current at TC = 155 °C, defining continuous conduction capability in thermally managed designs. |
| VF (typ) | 1.35 V @ IF = 10 A, Tj = 25 °C - Low conduction loss reduces power dissipation by ~30 % vs. comparable Si FRD. |
| Tj (max) | +175 °C - Supports operation in high-ambient environments without derating, e.g., enclosed industrial enclosures. |
| Rth(j-c) | 0.65 °C/W (typ.) - Enables efficient heat transfer to heatsink; allows >15 W dissipation with ≤10 °C rise at case. |
| Qcj | 57 nC @ VR = 800 V - Low capacitive charge minimizes switching loss during hard-commutation events. |
| IR (max) | 400 µA @ Tj = 150 °C, VR = VRRM - Low leakage preserves efficiency in high-voltage standby and light-load conditions. |
Pinout & Package
STPSC10H12G-TR is housed in a surface-mount D²PAK (TO-263) package with two terminals: anode and cathode. The tab is electrically connected to the cathode and serves as the primary thermal path. Mounting requires solder reflow per JEDEC J-STD-020 profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Input current terminal | Connects to AC/switching node side; carries full forward current into device. |
| Cathode (tab + lead 2) | Output current terminal & thermal interface | Electrically and thermally ties to output rail; must be soldered to ≥6.85 mm × 7.25 mm copper area for rated Rth(j-c). |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery (Qrr ≈ 0) | Eliminates turn-off switching loss and associated voltage overshoot/ringing in boost PFC and LLC resonant converters. |
| Temperature-stable VF & Cj | Forward voltage increases only ~0.4 V from 25 °C to 150 °C; capacitance varies <20 % over full VR range - simplifies thermal design. |
| High surge robustness | IFSM = 60 A @ TC = 150 °C (10 ms sine) - withstands inrush and fault currents without degradation in motor drives and UPS systems. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free requirements - supports global environmental compliance without performance trade-offs. |
| Wide operating temperature | Rated from -40 °C to +175 °C - enables deployment in under-hood automotive auxiliary supplies and industrial outdoor power systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1200 V SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10120A-TR | Same 1200 V/10 A rating; TO-220-2L package; Rth(j-c) = 1.0 °C/W (higher than ST's 0.65 °C/W); VF = 1.5 V @ 10 A. | Requires larger heatsink area due to higher thermal resistance; less suitable for space-constrained D²PAK layouts. | Select when TO-220 mounting is preferred and board-level thermal management permits higher Rth. |
| SS12120A-TR | 1200 V/10 A; D²PAK package; VF = 1.45 V @ 10 A; Tj(max) = +175 °C; Rth(j-c) = 0.75 °C/W. | Marginally higher VF and thermal resistance reduce efficiency by ~0.3 % and require 15 % more copper area. | Consider for cost-sensitive programs where 0.1 V VF penalty and 0.1 °C/W Rth increase are acceptable. |
Compared with C3D10120A-TR and SS12120A-TR, STPSC10H12G-TR delivers the lowest VF (1.35 V) and best thermal performance (0.65 °C/W) in D²PAK, making it optimal for high-density, high-efficiency 1200 V rectification where thermal headroom and conduction loss are critical.

FAQ
What is the maximum recommended PCB copper area for thermal performance in D²PAK layout?
The datasheet specifies a minimum copper area of 6.85 mm × 7.25 mm (≈50 mm²) under the cathode tab to achieve the rated 0.65 °C/W junction-to-case thermal resistance. Using ≥105 mm² (e.g., 10.5 mm × 10 mm) with 2 oz copper improves Rth(j-a) to ~35 °C/W on FR4, enabling higher continuous current in convection-cooled designs.
Does STPSC10H12G-TR require gate drive or external control circuitry?
No - it is a passive two-terminal Schottky rectifier with no gate or control input. It operates solely based on forward bias polarity and current magnitude. Unlike MOSFET-based synchronous rectifiers, it needs no timing signals, drivers, or dead-time management, simplifying layout and reducing system component count.
Can this diode replace a 1200 V Si fast recovery diode in an existing design without layout changes?
Yes, if the original design uses a D²PAK footprint and thermal pad layout matching ST's mechanical drawing (Table 8). Electrical replacement is drop-in: same pinout, polarity, and voltage rating. However, reduced switching loss may lower MOSFET/IGBT stress - verify gate driver slew rate and snubber values are still appropriate given eliminated reverse recovery ringing.
Is STPSC10H12G-TR qualified for automotive applications per AEC-Q101?
No - STPSC10H12G-TR is not AEC-Q101 qualified. It is rated for industrial temperature range (-40 °C to +175 °C) and intended for industrial, solar, and EV charging applications. For automotive under-hood use, ST offers the AEC-Q101-qualified STPSC10H12GY-TR variant with identical electrical specs but additional qualification testing.
