Diodes Incorporated DSC10C065

Overview

DSC10C065 from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 10 A average forward current, and maximum 1.7 V forward voltage at 10 A and +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 industrial motor drives and UPS systems.

For engineers reviewing the DSC10C065 datasheet, DSC10C065 pinout, DSC10C065 application, or DSC10C065 equivalent, key selection criteria include its 4 °C/W junction-to-case thermal resistance, 1.2 µA typical reverse leakage at 650 V and +25°C, fast reverse recovery behavior, positive temperature coefficient of VF, and TO220AC (Type WX) package compatibility with standard heatsink mounting.

Technical Context

This SiC Schottky diode eliminates minority-carrier storage delay, enabling zero reverse recovery charge (QRR ≈ 0) and near-ideal switching behavior. Its unipolar conduction mechanism delivers low forward voltage drift over temperature and minimal capacitive charge (QC = 27 nC at VR = 400 V).

Designed for high-frequency, high-efficiency topologies, it operates reliably up to +175°C junction temperature with a 132 µA typical IR at +175°C and 650 V reverse bias. The device exhibits a predictable, linear increase in VF with temperature-critical for thermal stability in tightly regulated power stages.

FAQ

Is the DSC10C065 pin-compatible with standard TO220AC rectifiers?

Yes-the DSC10C065 uses the industry-standard TO220AC (Type WX) outline with identical mechanical dimensions, lead spacing, and mounting hole location as legacy Si rectifiers. The tab is cathode-connected, matching conventional TO220AC diode orientation, enabling drop-in replacement without PCB redesign.

What is the maximum recommended case temperature for continuous operation?

The absolute maximum case temperature is +175°C, but continuous operation above +135°C requires derating per Figure 1. At +125°C case temperature, the average forward current must be reduced to approximately 7.2 A to maintain safe junction temperature, assuming R_θJC = 4 °C/W and no additional thermal interface resistance.

Does the DSC10C065 require a gate resistor or snubber network?

No-unlike SiC MOSFETs or IGBTs, this Schottky diode has no gate terminal and exhibits no reverse recovery charge. Snubbers are unnecessary in most applications; however, a small RC network (e.g., 100 Ω + 100 pF) may be added across the diode in ultra-high-di/dt (>500 A/µs) inverter legs to suppress parasitic oscillation from layout inductance.

Can the DSC10C065 be used in automotive under-hood applications?

While not AEC-Q101 qualified out-of-box, Diodes Incorporated offers automotive-grade variants (e.g., DSC10C065Q) with PPAP documentation, IATF 16949 manufacturing, and extended test coverage. Standard DSC10C065 is rated for −55°C to +175°C operation and may be used in non-safety-critical automotive auxiliary systems pending customer qualification.
