Product details

Overview

STPSC10H065DI from STMicroelectronics is a 10 A, 650 V silicon carbide (SiC) Schottky power diode in an insulated TO-220AC package. It delivers zero reverse recovery charge, temperature-independent switching, and 90 A non-repetitive surge capability (tp = 10 ms, Tc = 25 °C), enabling high-efficiency PFC stages in industrial SMPS.

For engineers reviewing the STPSC10H065DI datasheet, STPSC10H065DI pinout, STPSC10H065DI application, or STPSC10H065DI equivalent, key selection criteria include its 2500 VRMS insulation rating, 7 pF typical package capacitance, 2.1 °C/W typical junction-to-case thermal resistance, and suitability for hard-switching LLC and boost topologies requiring robust transient handling.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-efficiency power conversion. Its wide bandgap enables a 650 V blocking voltage with low forward voltage (1.56 V typ. at 10 A, 25 °C) and negligible turn-off ringing due to absence of minority-carrier storage.

Thermal performance is defined by Rth(j-c) = 2.1 °C/W (typ.) and Tj(max.) = 175 °C, supporting operation under high ambient conditions when mounted on heatsinks. The insulated TO-220AC package provides galvanic isolation critical for floating-ground topologies like bridgeless PFC.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - Maximum repetitive reverse voltage; sets system-level DC bus rating for 400–450 V PFC outputs.
I_F(AV)	10 A - Average forward current at T_C = 85 °C (insulated package); defines continuous conduction capability in boost inductors.
I_FSM	90 A - Non-repetitive surge current (10 ms sine, T_C = 25 °C); ensures robustness during line transients and startup surges.
V_F	1.56 V (typ., 10 A, 25 °C) - Low forward drop reduces conduction losses vs. Si FRDs; increases efficiency in >100 kHz designs.
R_th(j-c)	2.1 °C/W (typ.) - Junction-to-case thermal resistance; determines heatsink sizing for 175 °C max junction operation.
C_j	48 pF (at V_R = 400 V) - Low reverse-biased junction capacitance minimizes capacitive turn-off loss and EMI in hard-switched converters.
Q_CJ	28.5 nC - Total capacitive charge; directly impacts switching loss in resonant and quasi-resonant topologies.

Pinout & Package

The STPSC10H065DI uses an insulated TO-220AC package with creepage/clearance enhanced for 2500 VRMS isolation. Mounting tab is electrically isolated from the cathode terminal.

Pin/Terminal	Circuit Role	Design Meaning
Tab (isolated)	Mounting surface / heatsink interface	Electrically isolated per UL/IEC standards; enables direct mounting to grounded chassis without additional insulation.
Anode (lead 1)	Current entry point	Connected to input side of boost inductor or AC rectifier output; carries full load current during conduction phase.
Cathode (lead 2)	Current exit point	Connected to switching node (e.g., MOSFET drain); sustains 650 V reverse bias during off-state with <100 µA leakage at 25 °C.

Key Features

Feature	Design Value
No reverse recovery charge	Eliminates reverse recovery loss and associated EMI; enables clean hard-switching up to 500 kHz in PFC.
Temperature-independent switching	Capacitive turn-off behavior stable from –40 °C to +175 °C; avoids timing drift in thermally varying environments.
High forward surge capability	90 A I_FSM (10 ms) supports inrush current handling in offline SMPS without derating or external fusing.
Insulated TO-220AC package	2500 VRMS isolation withstand and 7 pF package capacitance reduce common-mode noise and simplify safety-compliant layout.
ECOPACK®2 compliance	Meets RoHS, halogen-free, and lead-free requirements; qualified for industrial and energy infrastructure applications.

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 10 A / 650 V rating; D²PAK package (R_th(j-c) = 1.5 °C/W); no insulation; higher C_j (60 pF @ 400 V).	Requires external insulator for chassis-mount; better thermal performance but unsuitable for direct-insulated mounting.	Select when heatsink isolation is handled externally and lower thermal resistance is prioritized over integrated insulation.
SS10065 (GeneSiC)	10 A / 650 V; TO-220AC non-insulated; V_F = 1.7 V (typ.); I_FSM = 85 A; R_th(j-c) = 1.8 °C/W.	Lacks 2500 VRMS isolation; higher forward drop increases conduction loss by ~9% at 10 A.	Choose where isolation is implemented at board level and cost sensitivity outweighs efficiency gain from lower V_F.

Compared with C3D10065A and SS10065, STPSC10H065DI uniquely integrates 2500 VRMS insulation into the TO-220AC form factor-enabling simplified mechanical design and reduced BOM count in safety-critical PFC modules-while maintaining competitive V_F, Q_CJ, and surge robustness.

FAQ

What is the maximum recommended case temperature for continuous operation?

The STPSC10H065DI is rated for I_F(AV) = 10 A at T_C = 85 °C when used in the insulated TO-220AC package. Exceeding this case temperature requires derating per the I_F vs. T_C curve in Figure 5 of DS9226, with absolute maximum junction temperature limited to 175 °C.

Does the insulated package affect thermal performance compared to standard TO-220AC?

Yes-the insulated TO-220AC variant has higher thermal resistance: R_th(j-c) = 2.1 °C/W (typ.) versus 1.25 °C/W for non-insulated TO-220AC. This reflects added dielectric layers; heatsink interface must be optimized using thermal paste and flatness control to maintain T_j ≤ 175 °C.

Can STPSC10H065DI replace silicon fast recovery diodes in existing designs?

Yes, with layout and gate-drive adjustments. Its zero Q_rr eliminates snubber circuits but may increase dv/dt stress on adjacent MOSFETs; verify voltage overshoot with oscilloscope measurements and consider minor gate resistor tuning to manage switching edge rates.

Is the device suitable for bidirectional operation such as in totem-pole PFC?

No-it is a unidirectional Schottky diode. In totem-pole PFC, it functions only in the boost rectification path (AC-to-DC direction). Bidirectional current flow requires complementary active switches (e.g., SiC MOSFETs) controlled by dedicated gate drivers; STPSC10H065DI does not conduct in reverse bias beyond V_RRM.
