MSC2X30SDA170J

Overview

The MSC2X30SDA170J is a dual Silicon Carbide Schottky Barrier Diode (SBD) manufactured by Microchip Technology. It features two anti-parallel diodes housed in an isolated SOT-227 package. The device supports a maximum DC reverse voltage of 1700 V and a maximum DC forward current of 30 A at 100 °C. Static characteristics include a typical forward voltage of 1.5 V at 30 A and 25 °C, with a maximum reverse leakage current of 200 μA at 1700 V. Thermal performance specifies a junction-to-case thermal resistance of 0.45 °C/W typical.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm pin configuration and internal topology. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors prior to procurement. Ensure application requirements align with the absolute maximum ratings provided in the datasheet.

Selection Notes

Select this component for high-voltage applications requiring low switching losses and high thermal efficiency. The isolated SOT-227 package facilitates direct mounting to heatsinks, reducing system complexity. Evaluate thermal management needs based on the specified junction-to-case thermal resistance and operating temperature range up to 175 °C.

Part Context

This device belongs to the Microsemi silicon carbide power Schottky barrier diode product line, now part of Microchip Technology. The series offers performance improvements over traditional silicon diodes while lowering total cost of ownership for high-voltage systems. The dual configuration allows for versatile circuit topologies within a single compact package.

Replacement Considerations

The MSC2X31SDA170J serves as a functional substitute within the same datasheet family, differing only in internal parallel versus anti-parallel diode configuration. Verify that the replacement matches the required circuit topology before implementation.
