Diodes Incorporated DSC10065

Overview

DSC10065 from Diodes Incorporated is a 650 V, 10 A silicon carbide Schottky diode in TO220AC (Type WX) package, designed for high-efficiency power conversion where low conduction loss and fast switching are critical. It delivers VF ≤ 1.7 V at 10 A and +25°C, IR ≤ 1.8 µA at 650 V and +25°C, and exhibits positive temperature coefficient on VF-enabling stable parallel operation in industrial motor drivers and UPS systems.

For engineers reviewing the DSC10065 datasheet, DSC10065 pinout, DSC10065 application, or DSC10065 equivalent, key selection criteria include its 60 A non-repetitive surge rating, 2 °C/W junction-to-case thermal resistance, 23 nC total capacitive charge at 400 V, and verified performance up to +175°C junction temperature in PFC and inverter rectification roles.

Technical Context

The DSC10065 employs a planar SiC Schottky barrier structure optimized for zero reverse recovery charge (Qrr ≈ 0), eliminating minority-carrier storage and enabling high-frequency operation without tail current. Its VF increases with temperature (positive TC), improving current sharing in paralleled configurations.

Thermal design is enabled by direct-mount capability to copper heatsinks (50 mm × 50 mm × 1.6 mm), supported by low RθJC = 2 °C/W and RθJL = 2 °C/W. The device sustains full 10 A average forward current up to +125°C case temperature per derating curve.

FAQ

Is DSC10065 suitable for automotive applications?

No-DSC10065 is not qualified to AEC-Q101 and lacks PPAP documentation or IATF 16949 manufacturing certification. Diodes explicitly states that automotive-grade variants require direct consultation and custom qualification; this part is intended for industrial and computing power systems only.

What is the thermal interface requirement for DSC10065?

The device requires mounting to a copper heatsink measuring 50 mm × 50 mm × 1.6 mm to achieve the specified RθJC = 2 °C/W. Thermal interface material (TIM) with ≤ 0.2 °C·in²/W resistance is recommended; mechanical clamping force must ensure uniform contact across the isolated tab surface.

Does DSC10065 have reverse recovery time (trr) specification?

No-DSC10065 is a majority-carrier SiC Schottky diode with no minority-carrier storage; therefore, it has no measurable trr. Its switching behavior is governed by junction capacitance discharge, quantified as total capacitive charge (QC = 23 nC), not reverse recovery charge (Qrr ≈ 0).

Can DSC10065 be paralleled for higher current handling?

Yes-its positive temperature coefficient on VF enables inherent current balancing. Parallel operation requires matched layout symmetry, identical thermal paths, and shared heatsinking. Derate total current by 15% for two devices and 25% for three or more to account for thermal coupling and trace impedance mismatch.
