Product details

Overview

STPSC10H065DY from STMicroelectronics is an AEC-Q101-qualified 650 V, 10 A average forward current silicon carbide Schottky diode in TO-220AC package, featuring negligible reverse recovery, temperature-independent switching, and 90 A non-repetitive surge capability - deployed in automotive and industrial PFC stages operating up to 175 °C junction temperature.

For engineers reviewing the STPSC10H065DY datasheet, STPSC10H065DY pinout, STPSC10H065DY application, or STPSC10H065DY equivalent, key selection criteria include zero-recovery behavior under hard-switching, thermal robustness at T_j = 175 °C, low C_j (48 pF @ 400 V), high I_FSM (90 A), and ECOPACK®2 compliance for automotive-grade supply chains.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in continuous conduction mode (CCM) PFC boost converters, eliminating reverse recovery losses and associated EMI. Its wide bandgap enables stable VF drift (< 2.5 V @ 150 °C, 10 A) and minimal capacitive charge (Q_CJ = 28.5 nC @ 400 V).

The device operates with junction-to-case thermal resistance of 1.5 °C/W max and supports DC and sinusoidal surge waveforms (tp = 10 ms, 90 A @ T_c = 25 °C). Reverse leakage remains below 425 µA at 150 °C and V_RRM, enabling reliable operation in high-temperature automotive under-hood environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - blocks full-line transients in 400 V AC input PFC stages without derating
I_F(AV)	10 A @ T_c = 135 °C - defines continuous conduction capability with standard heatsink mounting
I_FSM	90 A @ tp = 10 ms, T_c = 25 °C - withstands inrush and overload surges without failure
V_F	1.75 V max @ 10 A, 25 °C - sets conduction loss baseline; rises to 2.5 V @ 150 °C, limiting thermal runaway risk
C_j	48 pF @ 400 V, 25 °C - determines high-frequency turn-off dv/dt immunity and snubber sizing
R_th(j-c)	1.5 °C/W max - enables thermal design with ≤15 °C rise per 10 W dissipation into TO-220AC heatsink
T_j(max)	175 °C - supports operation in engine control units and on-board chargers without active cooling

Pinout & Package

TO-220AC package: insulated case, single-drain tab, 3-pin vertical through-hole mounting. Thermal path optimized via metal tab soldered directly to PCB copper pour or external heatsink using 0.55 N·m torque.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Pin 1)	Forward current entry point	Connected to PFC boost inductor node; requires low-inductance layout to minimize ringing
Cathode (Pin 2)	Forward current exit / high-side return	Directly tied to output capacitor positive rail; serves as main power return path
Case / Tab (Pin 3)	Thermal interface & electrical ground reference	Internally connected to cathode; must be electrically isolated from chassis unless system grounding permits

Key Features

Feature	Design Value
No reverse recovery charge (Q_rr ≈ 0)	Eliminates switching loss and EMI spikes in 65–100 kHz PFC stages, reducing MOSFET stress and heatsink size
AEC-Q101 qualification	Validated for automotive powertrain and charging systems including temperature cycling, HTRB, and ESD testing
ECOPACK®2 compliance	Halogen-free, RoHS-compliant epoxy meets UL94 V0 flammability rating for safety-critical modules
High I_FSM (90 A)	Survives cold-start surges and line-dip recovery events without bond-wire fusing or parameter shift
Stable C_j vs. voltage	Capacitance drops only 10% from 0 V to 400 V, enabling predictable snubber design across full operating range

Equivalent & Alternatives

The following parts are listed as comparable options for similar SiC Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
C3D10065A (Wolfspeed)	Same 650 V/10 A rating; R_th(j-c) = 1.4 °C/W; higher V_F (1.85 V typ. @ 10 A, 25 °C)	Requires tighter thermal design due to higher conduction loss; not AEC-Q101 qualified	Preferred where cost sensitivity outweighs automotive qualification requirements
SS10P6 (ON Semiconductor)	Si-based PFC diode; V_RRM = 600 V; Q_rr = 45 nC; T_j(max) = 150 °C	Limited to lower-power, non-automotive designs due to recovery losses and lower temperature rating	Only suitable for legacy 1–3 kW designs where SiC cost premium is prohibitive

Compared with C3D10065A and SS10P6, STPSC10H065DY uniquely combines AEC-Q101 qualification, zero Q_rr, and 175 °C operation - making it the sole choice for thermally constrained automotive PFC where reliability and EMI compliance are mandatory.

FAQ

Is STPSC10H065DY pin-compatible with standard TO-220AC silicon diodes?

Yes - it uses identical TO-220AC mechanical footprint and pin assignment (Anode–Cathode–Tab), allowing direct replacement in existing layouts. However, its lower forward voltage and zero recovery require verification of gate drive timing margins and snubber values to avoid overvoltage stress on switching MOSFETs.

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies I_F(AV) = 10 A at T_c = 135 °C, with absolute maximum T_j = 175 °C. Using R_th(j-c) = 1.5 °C/W, sustained operation at T_c > 140 °C risks exceeding T_j(max) under full load; thermal design must maintain T_c ≤ 135 °C for rated current.

Does STPSC10H065DY require a negative bias to suppress leakage at high temperature?

No - unlike some SiC diodes, this part exhibits no significant leakage increase requiring active clamping. At T_j = 175 °C and V_R = 650 V, IR remains < 1000 µA (extrapolated from 425 µA @ 150 °C), well within typical PFC bus hold-up design margins.

Can STPSC10H065DY be used in parallel configurations?

Yes - its positive V_F temperature coefficient (VF increases with T_j) enables natural current sharing. Parallel operation requires matched layout impedance, identical heatsinking, and ≤5 % V_F unit-to-unit variation (guaranteed by ST's binning process per datasheet Section 4).
