Product details
Overview
DSC10A065D1 from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 10 A average rectified output current, and 1.5 V maximum forward voltage at +25°C. It serves as a high-efficiency rectifier or freewheeling diode in power conversion stages requiring low conduction loss and stable high-temperature operation, such as PFC circuits and industrial inverters.
For engineers reviewing the DSC10A065D1 datasheet, DSC10A065D1 pinout, DSC10A065D1 application, or DSC10A065D1 equivalent, key selection criteria include its 2.3 µA typical reverse leakage at 650 V/25°C, 3 °C/W junction-to-case thermal resistance, TO252 (Type WX) package mounting compatibility, and verified performance up to +175°C junction temperature.
Technical Context
This SiC Schottky diode eliminates minority-carrier storage delay, enabling zero reverse recovery charge (Qrr ≈ 0) and eliminating switching tail current. Its positive temperature coefficient on VF ensures inherent current sharing in parallel configurations.
Designed for hard-switched topologies, it delivers 23 nC total capacitive charge (Qc) at 400 V reverse bias and 10 A forward current, with junction capacitance ranging from 88 pF (VR = 40 V) to 434 pF (VR = 0.1 V), supporting high-frequency operation in SMPS and UPS systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Wolfspeed C4D10065A | Same 650 V/10 A rating; VF = 1.55 V (max) at 10 A/25°C; RθJC = 2.5 °C/W. | Slightly lower thermal resistance enables higher power density; requires tighter layout for gate-drive isolation. | Preferred where board space is constrained and thermal interface material optimization is feasible. |
| ON Semiconductor NS10A65S | 650 V/10 A; VF = 1.65 V (max); IR = 3.5 µA @ 650 V/25°C; RθJC = 3.5 °C/W. | Higher leakage and thermal resistance limit use in high-ambient industrial environments. | Suitable for cost-sensitive designs where 175°C operation is not required and heatsinking is less aggressive. |
Compared with C4D10065A and NS10A65S, the DSC10A065D1 offers the lowest IR at 25°C (2.3 µA), best balance of VF and thermal resistance for TO252 mounting, and documented suitability for PFC and motor drive derating curves per Figure 1.

FAQ
What is the maximum junction temperature rating for DSC10A065D1?
The DSC10A065D1 is rated for continuous operation from –55°C to +175°C junction temperature. Its thermal resistance (RθJC = 3 °C/W) and low IR drift up to 175°C make it suitable for enclosed industrial enclosures and under-hood automotive auxiliary systems where ambient temperatures exceed 100°C.
Can DSC10A065D1 replace a silicon fast recovery diode in an existing PFC design?
Yes-its zero Qrr and 1.5 V VF enable direct substitution in boost PFC stages, but layout must accommodate the TO252 cathode pad thermal connection and verify snubber adjustments due to reduced switching loss and faster voltage transitions.
Is DSC10A065D1 qualified for automotive applications?
No-the device is not AEC-Q101 qualified. While it operates reliably up to +175°C, Diodes specifies that automotive-grade variants require explicit PPAP documentation and IATF 16949 manufacturing; contact Diodes directly for AEC-compliant alternatives like the DSC10A065D1Q.
What is the recommended PCB pad layout for optimal thermal performance?
Per Diodes' outline drawing, use a minimum 1 in² (25.4 mm²) 2 oz copper pad connected via ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch) to internal ground planes. The pad must match the TO252 (Type WX) exposed cathode dimensions: 5.33 mm × 6.10 mm, with solder mask defined for full wetting.
