Diodes Incorporated DSC04A065FP

Overview

DSC04A065FP from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 4 A average rectified output current, and 1.5 V maximum forward voltage at +25°C. It serves as a high-efficiency rectifier or freewheeling diode in power factor correction circuits, industrial motor drives, and SMPS topologies operating up to +175°C junction temperature.

For engineers reviewing the DSC04A065FP datasheet, DSC04A065FP pinout, DSC04A065FP application, or DSC04A065FP equivalent, key selection criteria include its low 1.4 µA typical reverse leakage at 650 V/25°C, 6 °C/W junction-to-case thermal resistance, fast reverse recovery, positive temperature coefficient on VF, and ITO220AC package compatibility with standard heatsinking footprints.

Technical Context

This SiC Schottky diode eliminates minority-carrier storage delay, enabling zero reverse recovery charge (Qrr ≈ 0) and near-ideal switching behavior. Its wide-bandgap material delivers stable reverse leakage (<117 µA at 650 V/175°C) and maintains forward conduction integrity across -55°C to +175°C ambient operation.

The device uses a planar junction structure with optimized anode metallization for low series resistance and uniform electric field distribution. Its 191 pF junction capacitance at 0.1 V reverse bias supports high-frequency snubberless operation in hard-switched converters above 100 kHz.

Key Specifications

Pinout & Package

Supplied in the industry-standard ITO220AC (Type WX-NC) package - a 3-terminal molded plastic power package with matte tin-plated copper leadframe, UL 94V-0 flammability rating, and 1.497 g mass. Designed for vertical mounting with case-isolated cathode connection and mechanical stability under thermal cycling.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SiC Schottky diode applications.

Compared with C3D04065E, DSC04A065FP offers lower VF (1.5 V vs. 1.7 V), reducing conduction loss in high-duty-cycle PFC stages; versus SS14HE3_A/H, it provides 16× higher voltage capability but requires careful thermal management due to higher VF and junction temperature sensitivity.

FAQ

Is DSC04A065FP suitable for automotive applications?

No - DSC04A065FP is not AEC-Q101 qualified. While it operates from -55°C to +175°C and meets RoHS 3 and halogen-free requirements, Diodes specifies that automotive-grade variants require explicit PPAP documentation and IATF 16949-certified manufacturing, which this part does not carry. Use only in industrial, computing, or telecom applications unless validated per customer-specific automotive change control processes.

What is the recommended heatsink interface for DSC04A065FP?

Mount the ITO220AC tab directly to a flat, oxidized-free copper heatsink using thermal interface material rated for >175°C continuous operation (e.g., ceramic-filled silicone grease or phase-change pads). Apply 0.5–0.7 N·m torque to M3 screws; avoid over-tightening to prevent package cracking. The 6 °C/W RθJC assumes a 50 mm × 50 mm × 1.6 mm copper heatsink per JESD-51 test conditions.

Does DSC04A065FP have a specified reverse recovery time (trr)?

No - as a majority-carrier SiC Schottky diode, DSC04A065FP exhibits no reverse recovery time or stored charge. Its switching behavior is governed solely by junction capacitance discharge; measured total capacitive charge (QC) is 12 nC at 400 V reverse bias, confirming absence of Qrr-related losses. This eliminates trr specification in datasheets per JEDEC standards for Schottky devices.

Can DSC04A065FP be paralleled for higher current handling?

Yes - its positive temperature coefficient on forward voltage enables natural current sharing. Parallel operation requires matched layout impedance (trace length, width, and via count), identical thermal mounting conditions, and individual current-sense verification. Derate total current by 15% versus sum of individual IO ratings to account for thermal coupling and manufacturing tolerances in VF (±0.12 V).
