Diodes Incorporated DSC06C065D1-13

Overview

DSC06C065D1 from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 6 A average rectified output current, and 1.7 V maximum forward voltage at +25°C with 6 A forward current. It serves as a high-efficiency, high-temperature rectifier or freewheeling diode in switched-mode power supplies and industrial inverters.

For engineers reviewing the DSC06C065D1 datasheet, DSC06C065D1 pinout, DSC06C065D1 application, or DSC06C065D1 equivalent, key selection criteria include its 2 °C/W junction-to-case thermal resistance, 4.2 µA typical reverse leakage at 650 V and +25°C, fast reverse recovery behavior, TO252 (Type WX) package compatibility, and stable VF temperature coefficient.

Technical Context

This SiC Schottky diode operates without minority-carrier storage, enabling near-zero reverse recovery charge (QC = 15 nC) and eliminating switching tail current. Its positive temperature coefficient of forward voltage ensures inherent current sharing in parallel configurations.

Rated for continuous operation from –55°C to +175°C, it maintains low leakage (<228 µA at 650 V and +175°C) and stable capacitance (125–184 pF across 0.1–40 V reverse bias), supporting high-frequency hard-switching topologies in PFC and UPS systems.

FAQ

What is the maximum allowable case temperature for continuous operation?

The DSC06C065D1 supports continuous operation up to +175°C case temperature, verified per JESD-51 thermal testing with a 75 mm × 75 mm × 2.0 mm copper heatsink. Derating begins above +125°C per Figure 1, where average forward current drops linearly to 3.5 A at +175°C.

Does this diode require a gate driver or external control circuitry?

No - the DSC06C065D1 is an uncontrolled two-terminal device with no gate terminal. It conducts when anode voltage exceeds cathode voltage by >1.5 V and blocks when reverse biased. No driver, biasing, or timing circuitry is needed, simplifying layout in rectifier and clamp roles.

Can DSC06C065D1 be used in parallel for higher current handling?

Yes - its positive temperature coefficient of forward voltage enables natural current sharing. Parallel operation requires matched trace lengths, symmetric thermal mounting, and shared cathode copper pour. Derate total current by 15% versus sum of individual ratings to account for thermal coupling effects.

Is the TO252 (Type WX) package thermally enhanced compared to standard TO252?

Yes - the Type WX variant features an enlarged exposed drain pad and optimized internal leadframe geometry, achieving R_θJC = 2 °C/W (vs. ~3.5 °C/W for standard TO252 Si diodes). This is validated with 75 mm² copper heatsink per JESD-51-14, enabling higher power density in motor drive and UPS designs.
