Diodes Incorporated DSC06C065

Overview

DSC06C065 from Diodes Incorporated is a 650 V, 6 A silicon carbide Schottky diode in TO220AC (Type WX) package, designed for high-efficiency power conversion. It delivers low forward voltage (1.7 V max at 6 A, 25°C), ultra-low reverse leakage (2.2 µA typ at 650 V, 25°C), and fast reverse recovery-enabling use as a rectifier or freewheel diode in PFC stages of industrial SMPS.

For engineers reviewing the DSC06C065 datasheet, DSC06C065 pinout, DSC06C065 application, or DSC06C065 equivalent, key selection criteria include thermal resistance (RθJC = 4 °C/W), surge capability (IFSM = 29 A), junction temperature range (–55 to +175 °C), and SiC-specific benefits like positive VF temperature coefficient and stable leakage at elevated temperatures.

Technical Context

This SiC Schottky diode replaces silicon fast recovery diodes in high-frequency, high-temperature switching applications. Its zero reverse recovery charge (Qrr ≈ 0) eliminates switching losses associated with minority-carrier storage, while its 650 V blocking rating supports 400 V AC input PFC and 800 V DC bus architectures.

The device operates reliably up to +175 °C junction temperature, with leakage current remaining below 170 µA at 650 V and 175 °C. Its TO220AC (Type WX) package features a 3-terminal configuration-Anode, Cathode, and electrically isolated tab-optimized for heatsink mounting and thermal management in compact power modules.

FAQ

Is the DSC06C065 pin-compatible with standard silicon TO220AC rectifiers?

Yes-the DSC06C065 uses the industry-standard TO220AC (Type WX) outline with identical mounting hole spacing and lead pitch. Its tab is cathode-connected and electrically isolated, matching mechanical and thermal interface requirements of legacy Si rectifiers like MUR460 or BYV26E, enabling drop-in replacement in most layouts.

What is the maximum recommended case temperature for continuous operation?

The DSC06C065 supports continuous operation up to +150 °C case temperature, as confirmed by its derating curve (Figure 1). At this temperature, average forward current must be reduced to ~3.5 A to maintain junction temperature ≤ +175 °C, assuming RθJC = 4 °C/W and no additional ambient thermal resistance.

Does the DSC06C065 require a gate driver or external control signal?

No-it is a passive two-terminal device with no gate or control input. The DSC06C065 conducts when forward-biased and blocks when reverse-biased, operating autonomously like any Schottky diode. No driver, biasing, or timing circuitry is needed for basic rectification or freewheeling functions.

Can the DSC06C065 be used in automotive applications?

The DSC06C065 is not AEC-Q101 qualified. While its –55 to +175 °C rating meets automotive temperature requirements, Diodes Incorporated explicitly states that automotive-grade versions require separate qualification, PPAP capability, and IATF 16949 manufacturing-available only upon special request and not in the standard DSC06C065 orderable part number.
