Product details

Overview

STPSC10H12G2-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 compliant with IEC-60664-1.

For engineers reviewing the STPSC10H12G2-TR datasheet, STPSC10H12G2-TR pinout, STPSC10H12G2-TR application in OBC or PFC stages, or STPSC10H12G2-TR equivalent SiC diodes, this page provides verified electrical specs, thermal performance, package dimensions, and real-world design implications for hard-switching EV power systems.

Technical Context

This SiC Schottky diode eliminates minority-carrier storage and reverse recovery charge (Q_r ≈ 0), enabling clean turn-off with negligible ringing under hard-switching conditions. Its capacitive turn-off behavior-characterized by C_j = 725 pF at 0 V and Q_Cj = 57 nC at 800 V-is stable across -40 °C to 175 °C junction temperature.

The device leverages wide-bandgap SiC material to sustain 1200 V blocking while maintaining low conduction loss (V_F = 1.35 V typ. @ 10 A, 25 °C) and high surge robustness (I_FSM = 71 A @ 10 ms, T_c = 25 °C). Its D²PAK HV package ensures 0.65 °C/W typical junction-to-case thermal resistance and meets ECOPACK2 environmental compliance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1200 V - Enables direct use in 800 V EV battery systems with >50% voltage margin for transients and derating.
I_F(AV)	10 A - Rated average forward current at T_c = 155 °C, supporting continuous conduction mode in high-power PFC stages.
V_F (typ.)	1.35 V @ 10 A, 25 °C - Low conduction loss reduces thermal stress and improves system efficiency vs. silicon fast recovery diodes.
R_th(j-c)	0.65 °C/W (typ.) - Enables compact heatsink design; 10 A operation yields ~6.5 °C junction rise above case at steady state.
C_j	725 pF @ 0 V - Low junction capacitance minimizes capacitive turn-on loss and EMI generation in MHz-range switching.
Creepage (A–K)	5.38 mm min. - Meets reinforced insulation requirements per IEC-60664-1 for 1200 V systems without additional PCB spacing.
T_j (max)	175 °C - Supports operation in high-ambient automotive environments (e.g., under-hood OBC) without derating.

Pinout & Package

Housed in D²PAK HV (TO-263-2HV) package: single-die, 2-terminal construction with isolated tab (anode-connected), epoxy body meeting UL94 V0, and enhanced creepage geometry. Dimensions per DS13404: L = 15.3–15.8 mm, W = 10.0–10.4 mm, H = 4.3–4.7 mm, creepage ≥5.38 mm (anode to cathode).

Pin/Terminal	Circuit Role	Design Meaning
Anode (Tab)	High-side power terminal / thermal path	Electrically and thermally connected to metal tab; requires insulated mounting in most topologies; carries full forward current.
Cathode (Lead)	Low-side power terminal	Standard gull-wing lead; connects to output rail or switching node; must be routed with low-inductance layout for minimal voltage overshoot.

Key Features

Feature	Design Value
No reverse recovery (Q_r ≈ 0)	Eliminates recovery-related switching losses and EMI, enabling higher-frequency PFC designs without snubbers.
Temperature-stable V_F and C_j	V_F increases only ~0.4 V from 25 °C to 150 °C; C_j variation <±15% - simplifies thermal design and control loop stability.
D²PAK HV creepage ≥5.38 mm	Permits direct use in 1200 V isolation barriers without conformal coating or slotting, reducing BOM and assembly cost.
I_FSM = 71 A (10 ms)	Withstands inrush and fault currents in OBC startup and short-circuit events without degradation.
ECOPACK2 compliance	Meets RoHS, halogen-free, and REACH requirements for automotive and industrial end equipment.

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; 1.55 V V_F (typ.) at 10 A; R_th(j-c) = 0.75 °C/W; TO-247-2L package.	Higher thermal resistance and larger footprint; less suitable for space-constrained OBC modules.	Prefer when higher surge rating (I_FSM = 80 A) or through-hole mounting is required.
SS12120	1200 V / 10 A; V_F = 1.45 V (typ.); R_th(j-c) = 0.85 °C/W; D²PAK package but standard (not HV) creepage (3.2 mm).	Lacks IEC-60664-1 compliance at 1200 V due to lower creepage; requires PCB slotting or coating.	Select only for non-safety-critical 800 V systems where creepage margin is relaxed.

Compared with C3D10120H and SS12120, STPSC10H12G2-TR offers the lowest V_F, best thermal resistance, and certified high-voltage creepage-making it optimal for compact, high-efficiency, safety-compliant EV power stages.

FAQ

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies I_F(AV) = 10 A at T_c = 155 °C, with absolute maximum T_j = 175 °C. Using R_th(j-c) = 0.65 °C/W (typ.), sustained 10 A conduction yields ~6.5 °C junction-to-case rise, allowing safe operation up to T_c = 168.5 °C before reaching T_j limit-provided heatsink design maintains that case temperature.

Does this diode require a gate resistor or snubber network?

No. As a Schottky diode with no reverse recovery charge (Q_r ≈ 0), STPSC10H12G2-TR does not generate turn-off voltage spikes or ringing. Snubbers are unnecessary in properly laid-out layouts; gate resistors apply only to MOSFETs/IGBTs-not to this passive diode.

How does its leakage current compare to silicon diodes at 150 °C?

At T_j = 150 °C and V_R = 1200 V, I_R ≤ 400 µA (max). This is 10–100× higher than silicon fast recovery diodes at same conditions-but remains manageable in PFC/OBC due to SiC's superior thermal conductivity and stable V_F offsetting conduction loss impact.

Can it replace a 1200 V silicon diode in an existing design without layout changes?

Yes-if the original uses a D²PAK-2 package. Pin-compatible replacement is possible, but verify thermal interface (tab mounting), PCB creepage (5.38 mm required), and reduced V_F (lower conduction loss may shift thermal balance). Layout changes are not needed, but thermal validation is recommended.
