Diodes Incorporated DSC06A065D1-13

Overview

DSC06A065D1 from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 6 A average rectified output current, and 1.5 V maximum forward voltage at +25°C. It serves as a high-efficiency rectifier or freewheeling diode in high-frequency, high-temperature power conversion stages including PFC circuits and industrial inverters.

For engineers reviewing the DSC06A065D1 datasheet, DSC06A065D1 pinout, DSC06A065D1 application, or DSC06A065D1 equivalent, key selection criteria include its low 0.5 µA typical reverse leakage at 650 V/25°C, 4 °C/W junction-to-case thermal resistance, fast reverse recovery, and TO252 (Type WX) package compatibility with high-power PCB layouts.

Technical Context

This SiC Schottky diode eliminates minority-carrier storage delay, enabling zero reverse recovery charge (Qrr ≈ 0) and minimal switching loss in hard-switched topologies. Its positive temperature coefficient on VF ensures inherent current sharing stability in parallel configurations.

Designed for continuous operation up to +175°C junction temperature, it maintains <200 µA IR at 650 V and +175°C, supported by a 2 °C/W junction-to-lead thermal path and robust 38 A non-repetitive surge rating (10 ms half-sine).

FAQ

What is the maximum allowable junction temperature for continuous operation?

The DSC06A065D1 supports continuous operation up to +175°C junction temperature, verified per JESD-51 thermal testing. Derating curves show usable average forward current down to ~3.5 A at +125°C case temperature, confirming robust high-temperature capability in enclosed or convection-limited environments.

Does this diode require a heatsink in standard TO252 PCB layouts?

Yes - the exposed cathode pad must be soldered to ≥1 in² (645 mm²) of 2 oz copper for RθJC = 4 °C/W performance. Without thermal copper, junction temperature rise exceeds safe limits at 6 A; recommended layout includes thermal vias under the pad and connection to internal ground or power planes.

How does its reverse leakage compare to silicon diodes at elevated temperatures?

At 650 V and +175°C, DSC06A065D1 exhibits ≤200 µA typical IR - over 100× lower than equivalent 650 V Si fast recovery diodes (>20 mA). This enables stable operation in high-temperature UPS and solar inverter DC-link stages where Si devices would thermally runaway.

Is the TO252 (Type WX) package compatible with standard reflow profiles?

Yes - the device is qualified to J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C, 20–40 sec). The matte tin finish on copper leadframe ensures reliable solderability per MIL-STD-202, Method 208, with no pre-bake required for dry storage conditions.
