Product details

Overview

STPSC10H12GY-TR from STMicroelectronics is an AEC-Q101-qualified 1200 V, 10 A automotive-grade silicon carbide Schottky rectifier in D²PAK package. It delivers negligible reverse recovery, temperature-independent switching, and 1.35 V typical forward voltage at 10 A and 25 °C. Designed for high-efficiency PFC and secondary-side rectification in EV chargers and industrial SMPS.

For engineers reviewing the STPSC10H12GY-TR datasheet, STPSC10H12GY-TR pinout, STPSC10H12GY-TR application, or STPSC10H12GY-TR equivalent, key selection criteria include its 1200 V V_RRM, 175 °C T_j(max), 0.65 °C/W R_th(j-c), 57 nC Q_Cj, and AEC-Q101 qualification for automotive power systems.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in hard-switching topologies by eliminating reverse recovery charge (Q_rr ≈ 0) and minimizing capacitive turn-off ringing. Its wide band-gap material enables stable VF and leakage behavior across -40 °C to +175 °C junction temperature range.

The device operates with zero minority-carrier storage, resulting in no temperature-dependent recovery tail. Its 725 pF junction capacitance at 0 V and 47 pF at 800 V supports predictable snubber design and EMI control in high-frequency PFC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1200 V - Withstands repetitive reverse voltage up to 1200 V without breakdown in PFC boost stages.
I_F(AV)	10 A - Average forward current rating at T_C = 155 °C, defining continuous conduction capability.
V_F(typ)	1.35 V @ 10 A, 25 °C - Low conduction loss enabling >98% efficiency in high-voltage rectification.
R_th(j-c)	0.65 °C/W - Enables thermal management with ≤65 K rise at 100 W dissipation under case cooling.
Q_Cj	57 nC @ 800 V - Total capacitive charge governing turn-off energy and snubber sizing in 100–300 kHz designs.
T_j(max)	175 °C - Supports operation in under-hood automotive environments and sealed industrial enclosures.
I_FSM	60 A @ 10 ms, T_C = 150 °C - Robust surge handling during inrush or overload transients in AC/DC front-ends.

Pinout & Package

STPSC10H12GY-TR uses the surface-mount D²PAK (TO-263) package with three terminals: Anode (pin 1), Cathode (pin 2), and exposed metal tab (pin 3, electrically connected to cathode). The tab serves as primary thermal path and must be soldered to a ≥8 cm² copper area per Figure 11 in the datasheet.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Pin 1)	AC input / switch node connection	Connects to PFC inductor output or LLC resonant tank; carries full load current during conduction.
Cathode (Pin 2)	DC output / bus connection	Routes rectified current to bulk capacitor; electrically tied to exposed tab for low-inductance return path.
Exposed tab (Pin 3)	Cathode thermal & electrical node	Provides primary heat conduction path; requires minimum 8 cm² 35 µm copper pour for R_th(j-a) ≤ 40 °C/W.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and charging systems per stress test requirements including HTGB, TC, and HTRB.
No reverse recovery	Eliminates Q_rr-related switching losses and EMI spikes, enabling clean turn-off in 100+ kHz PFC controllers.
175 °C operating T_j	Permits compact heatsinking and eliminates derating in high-ambient industrial or traction battery applications.
ECOPACK®2 compliant	Halogen-free, RoHS-compliant molding compound meeting automotive environmental standards without performance trade-offs.
0.65 °C/W R_th(j-c)	Enables direct mounting to aluminum baseplate or copper-clad PCB for thermal resistance <1.0 °C/W in production assemblies.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage SiC Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
C3D10120A	1200 V, 10 A; 1.55 V VF @ 10 A, 25 °C; 0.75 °C/W R_th(j-c); TO-247 package	Requires through-hole assembly and larger heatsink footprint; higher VF increases conduction loss by ~15%	Select when legacy TO-247 layout exists and board re-spin is not feasible.
SS12120	1200 V, 10 A; 1.45 V VF @ 10 A, 25 °C; 0.85 °C/W R_th(j-c); D²PAK package; no AEC-Q101	Lacks automotive qualification; junction temp limited to 150 °C; higher thermal resistance limits power density	Acceptable for industrial SMPS where AEC-Q101 and 175 °C operation are not required.

Compared with C3D10120A and SS12120, STPSC10H12GY-TR offers the lowest VF and best thermal performance in D²PAK, with AEC-Q101 validation essential for automotive OBC and traction systems-making it the preferred choice where reliability, efficiency, and package compatibility are jointly critical.

FAQ

Is STPSC10H12GY-TR pin-compatible with standard D²PAK silicon diodes?

No. While the D²PAK outline matches mechanical footprints, STPSC10H12GY-TR has cathode-connected tab and anode/cathode pin assignments aligned to SiC rectifier convention-not legacy Si FRD layouts. Verify PCB pad stack and thermal land against Figure 11 in DocID029346 Rev 2 before layout reuse.

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies I_F(AV) = 10 A at T_C = 155 °C. For reliable long-term operation, ST recommends limiting T_C to ≤145 °C to maintain margin on R_th(j-c) degradation and ensure 175 °C T_j is not exceeded under worst-case load and ambient conditions.

Does this diode require a gate resistor or driver circuit?

No. STPSC10H12GY-TR is a passive two-terminal Schottky rectifier with no gate terminal. It requires no drive circuitry, biasing, or timing control-unlike MOSFETs or IGBTs. Only proper thermal interface and layout for low-inductance current paths are needed.

Can STPSC10H12GY-TR replace a 1200 V Si fast recovery diode in an existing design?

Yes-with layout verification. Its zero Q_rr eliminates snubber dependency, but reduced junction capacitance (725 pF vs. ~2000 pF for Si FRD) may alter voltage overshoot dynamics. Recalculate RC snubbers and validate EMI performance; thermal design improves due to lower VF and better R_th(j-c).
