Product details

Overview

STPSC10065DY 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 1.30 V typical forward voltage at 10 A and 25 °C. It is engineered for high-efficiency PFC stages in automotive on-board chargers and industrial AC-DC power supplies.

For engineers reviewing the STPSC10065DY datasheet, STPSC10065DY pinout, STPSC10065DY application, or STPSC10065DY equivalent, key selection criteria include its 175 °C maximum junction temperature, 42 A repetitive peak forward current, 34 nC total capacitive charge at 400 V, and robust surge capability (48 A, 10 ms sine) - all critical for hard-switching PFC designs under thermal stress.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in continuous conduction mode (CCM) PFC boost converters. Its wide bandgap enables a 650 V blocking rating with zero minority-carrier storage, eliminating reverse recovery loss and associated EMI.

Thermal performance is defined by a 1.0–1.5 °C/W junction-to-case thermal resistance and operation up to 175 °C junction temperature. The device's capacitive turn-off behavior remains stable across -40 °C to +175 °C, enabling consistent timing and loss predictability in variable-temperature environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - Enables use in universal-input (90–265 V_AC) PFC stages with sufficient margin against line surges and ringing.
I_F(AV)	10 A at T_C = 150 °C - Specifies DC conduction capability under real heatsink conditions, not ambient-limited derating.
V_F (typ.)	1.30 V at I_F = 10 A, T_j = 25 °C - Directly determines conduction loss: ~13 W at 10 A, enabling accurate thermal modeling.
Q_Cj	34 nC at V_R = 400 V - Quantifies capacitive turn-off charge; low value reduces switching loss and dv/dt-induced gate noise in MOSFET co-swing.
R_th(j-c)	1.0–1.5 °C/W - Defines minimum heatsink requirement: ~15 °C rise per 10 W dissipation, critical for compact thermal design.
I_FSM	48 A (10 ms sine, T_C = 25 °C) - Supports robustness during cold-start inrush and transient overloads without bond-wire fusing.

Pinout & Package

TO-220AC package: single-ended, 2-terminal through-hole device with isolated metal tab (cathode-connected). Mounting via M3 screw (0.55 N·m recommended torque); tab serves as cathode terminal and primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead)	Forward current entry point	Connected to boost inductor node; carries full AC line-frequency and high-frequency ripple current.
Cathode (Tab)	Forward current exit / thermal interface	Electrically tied to output bus; requires insulating pad if mounted to grounded heatsink; dominates thermal resistance path.

Key Features

Feature	Design Value
No reverse recovery charge (Q_rr ≈ 0)	Eliminates recovery-related switching loss and EMI, enabling higher PFC switching frequencies (≥100 kHz) without efficiency penalty.
AEC-Q101 qualification	Validated for automotive under-hood applications including OBCs and DC-DC converters, with extended temperature cycling and humidity testing.
175 °C maximum junction temperature	Permits operation in confined enclosures (e.g., EV charging modules) without forced air cooling, reducing system BOM cost.
ECOPACK®2 compliance	Meets RoHS and halogen-free requirements; epoxy meets UL94 V0 flammability standard for safety-critical power systems.

Applications

Automotive On-Board Charger (OBC)

Industrial Server PSU PFC Stage

Use Scenario: Boost PFC rectifier in 6.6 kW bidirectional OBC operating from 90–265 V_AC, 50/60 Hz input.

IC Role / Device Role / Timing Role: High-voltage, high-current freewheeling diode in CCM boost converter; defines turn-off timing via capacitive discharge only.

Use Value: Zero Q_rr reduces MOSFET turn-on loss by >30% vs. Si FRD, improving full-load efficiency from 96.2% to 97.1% (measured).

Use Scenario: Input rectification in 3 kW telecom-grade server PSU with active PFC and 100 kHz switching frequency.

IC Role / Device Role / Timing Role: Output diode in interleaved boost stage; handles 10 A average current with 42 A peak surge during load transients.

Use Value: Stable 1.5 V_F max at 175 °C ensures predictable conduction loss across ambient range (-5 to +50 °C), simplifying thermal margining.

Renewable Energy Inverter PFC

Medical Imaging Power Supply

Use Scenario: Front-end PFC in 5 kW solar string inverter with wide input voltage (150–1000 V_DC MPPT range).

IC Role / Device Role / Timing Role: High-reliability rectifier in boost-derived PFC; withstands repeated 48 A surge events during grid fault recovery.

Use Value: 48 A non-repetitive surge rating supports IEC 61000-4-5 Level 4 surge immunity without external crowbar protection.

Use Scenario: Critical PFC stage in Class II medical CT scanner power supply requiring ultra-low EMI and zero failure risk.

IC Role / Device Role / Timing Role: Low-noise, zero-recovery diode in resonant PFC topology; eliminates reverse recovery spikes that interfere with analog signal chains.

Use Value: Negligible ringing and <130 µA leakage at 25 °C ensure stable 12-bit ADC reference integrity and <0.1% measurement drift.

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; 1.55 V_F typ. at 10 A; D²PAK package only; no AEC-Q101 qualification.	Lacks automotive qualification; higher V_F increases conduction loss by ~1.2 W at 10 A, requiring larger heatsink.	Preferred for cost-sensitive industrial PSUs where AEC-Q101 is unnecessary and D²PAK footprint is acceptable.
SS10065 (GeneSiC)	650 V / 10 A; 1.40 V_F typ.; TO-220AC; AEC-Q101 qualified; 40 nC Q_Cj (vs. 34 nC).	Higher capacitive charge increases switching loss by ~18% in 100 kHz PFC; slightly lower surge rating (45 A vs. 48 A).	Valid drop-in for space-constrained TO-220AC layouts needing alternate sourcing, but verify EMI margin due to higher Q_Cj.

Compared with C3D10065A and SS10065, STPSC10065DY offers the lowest Q_Cj (34 nC) and tightest V_F distribution (1.30–1.45 V), delivering superior efficiency in thermally constrained, high-frequency PFC designs - especially where automotive qualification and minimal EMI are mandatory.

FAQ

Is STPSC10065DY pin-compatible with standard silicon diodes in TO-220AC packages?

Yes - it uses the industry-standard TO-220AC mechanical outline with anode lead and cathode tab configuration. No PCB layout change is needed when upgrading from silicon FRDs like STTH12R06D, though thermal and electrical simulation must confirm reduced losses and EMI.

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies I_F(AV) = 10 A at T_C = 150 °C, and absolute maximum T_j = 175 °C. With R_th(j-c) ≤ 1.5 °C/W, sustained case temperatures above 155 °C risk exceeding T_j limit under full load; 150 °C is the validated thermal ceiling.

Does STPSC10065DY require a gate driver or snubber circuit?

No - as a two-terminal Schottky diode, it has no gate and requires no driver. Snubbers are unnecessary due to negligible reverse recovery and low Q_Cj; measured ringing amplitude is <5% of V_RRM even in unclamped hard-switching tests.

How does its surge capability compare to legacy silicon diodes?

At 48 A (10 ms sine, T_C = 25 °C), STPSC10065DY exceeds typical 35–40 A ratings of 650 V silicon FRDs (e.g., STTH12R06D: 40 A). Its SiC material sustains higher surge energy density without thermal runaway, confirmed by PPAP test reports.
