Diodes Incorporated DSC08065

Overview

DSC08065 from Diodes Incorporated is an 8A, 650V silicon carbide Schottky diode in TO220AC (Type WX) package, designed for high-efficiency rectification with VF ≤ 1.7 V at 8 A and 25°C, IR ≤ 0.51 µA at 650 V and 25°C, and RθJC = 3°C/W - used as a freewheel or blocking diode in industrial motor drivers and power inverters.

For engineers reviewing the DSC08065 datasheet, DSC08065 pinout, DSC08065 application, or DSC08065 equivalent, key selection criteria include its low conduction loss at high temperature, fast reverse recovery (QC = 17 nC), stable leakage up to +175°C, and compatibility with fin-type heatsinks per JESD-51 test conditions.

Technical Context

This SiC Schottky diode operates without minority-carrier storage, delivering zero reverse recovery charge in ideal conditions and minimal switching loss in hard-switched topologies. Its positive temperature coefficient on VF ensures current sharing stability in parallel configurations.

Rated for continuous operation from –55°C to +175°C junction temperature, it maintains <230 µA leakage at 650 V and +175°C, and withstands non-repetitive 48 A surge (8.3 ms half-sine) - enabling use in high-reliability industrial power stages where thermal margin and surge robustness are critical.

Key Specifications

Pinout & Package

Package: TO220AC (Type WX), 3-terminal through-hole package with isolated tab (cathode-connected tab). Mounting requires insulating washer when tab is not used as cathode return path.

FAQ

Is DSC08065 suitable for automotive applications?

No - DSC08065 is not qualified to AEC-Q101 and lacks PPAP documentation or IATF 16949 manufacturing certification. Diodes explicitly states that automotive-grade variants require direct contact with their representatives for change-controlled parts meeting AEC-Q100/101/200 standards.

What is the maximum allowable case temperature for continuous operation?

The DSC08065 supports continuous operation up to +175°C case temperature, as confirmed by its TJ, TSTG rating of –55°C to +175°C and derating curve (Fig.1), which shows usable current down to ~2.5 A at TC = 150°C with appropriate heatsinking.

Does DSC08065 have a built-in thermal protection feature?

No - DSC08065 is a passive two-terminal device with no integrated thermal shutdown or sensing circuitry. Thermal management relies entirely on external heatsinking, PCB copper area, and system-level monitoring; its RθJC = 3°C/W enables accurate junction temperature estimation using case temperature measurement.

Can DSC08065 be paralleled for higher current handling?

Yes - its positive temperature coefficient on VF enables stable current sharing without external ballast resistors. Parallel operation requires matched layout symmetry, identical thermal paths, and verification of <±5% VF mismatch at operating current and temperature per Diodes' application guidance.
