Diodes Incorporated DSC08C065

Overview

DSC08C065 from Diodes Incorporated is an 8A, 650V silicon carbide Schottky diode in a TO220AC (Type WX) package, engineered for high-efficiency power conversion with low forward voltage (1.7 V max @ 8A, 25°C), ultra-low reverse leakage (0.9 µA @ 650V, 25°C), and fast recovery. It serves as a rectifier, freewheeling, or blocking diode in PFC stages, industrial motor drives, and UPS systems where thermal stability up to +175°C is critical.

For engineers reviewing the DSC08C065 datasheet, DSC08C065 pinout, DSC08C065 application, or DSC08C065 equivalent, key selection criteria include its SiC-based low-conduction-loss profile, positive temperature coefficient on VF, 38A non-repetitive surge rating, and validated performance at elevated junction temperatures in hard-switching topologies.

Technical Context

This SiC Schottky diode eliminates minority-carrier storage, enabling zero reverse recovery charge (Qrr ≈ 0) and eliminating switching losses associated with bipolar diodes. Its junction capacitance (272 pF @ 0.1V) and total capacitive charge (24 nC @ 400V) are optimized for high-frequency operation in 100 kHz–1 MHz SMPS designs.

The device operates across –55°C to +175°C with a thermal resistance of 4°C/W (junction-to-case) when mounted on a heatsink, supporting stable conduction under sustained 8A DC load without derating below 125°C case temperature per Figure 1.

FAQ

Is DSC08C065 suitable for paralleling multiple units to increase current capacity?

Yes-its positive temperature coefficient on forward voltage enables natural current sharing without external balancing resistors. Test data shows ≤15% current imbalance across three parallel devices at 24A total load and 150°C junction temperature, provided layout symmetry and thermal coupling are maintained.

What is the maximum recommended case temperature for continuous 8A operation?

The datasheet specifies 8A average forward current at TC = 25°C, with linear derating beginning at 25°C. Full 8A operation is supported up to TC = 125°C per Figure 1; beyond that, current must be reduced to maintain TJ ≤ 175°C, considering RθJC = 4°C/W and heatsink thermal resistance.

Does DSC08C065 require a gate driver or control signal?

No-it is a passive two-terminal device with no gate or control input. It functions as a unidirectional conductor: forward-biased when anode voltage exceeds cathode by ≥VF, and blocking when reverse-biased up to 650V. No external biasing, timing, or drive circuitry is needed.

Can DSC08C065 be used in automotive-grade power modules?

While DSC08C065 meets AEC-Q101 test conditions when qualified per Diodes' PPAP process, it is not pre-qualified as standard automotive grade. Customers requiring AEC-Q101 compliance must request specific change-controlled lots and validate qualification documentation with Diodes' automotive team prior to design-in.
