MSC2X31SDA070J

Overview

The MSC2X31SDA070J is a dual parallel Silicon Carbide Schottky Barrier Diode (SBD) manufactured by Microchip Technology. It features a maximum DC reverse voltage of 700 V and a maximum DC forward current of 30 A at 90 °C case temperature. The device utilizes an isolated SOT-227 package with a junction-to-case thermal resistance of 0.95 °C/W typical. It supports an operating junction temperature range from -55 °C to 175 °C and provides isolation voltage up to 2500 V RMS.

Feature Summary

• Dual parallel configuration for high-current applications
• Zero reverse recovery charge for high-frequency efficiency
• Isolated package enabling direct heatsink mounting
• Rated for avalanche energy dissipation

Applications

• Power factor correction circuits
• Anti-parallel diodes in switch-mode power supplies, inverters, converters, and motor controllers
• Freewheeling diodes in switch-mode power supplies, inverters, and converters
• Snubber and clamp diode implementations

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm the exact internal configuration. The 'MSC2X31' designation indicates a parallel arrangement, whereas other suffixes may denote anti-parallel configurations. Ensure that procurement specifications align precisely with the required circuit topology before finalizing orders.

Selection Notes

Select this component for high-voltage, high-frequency power conversion systems requiring low switching losses. The SOT-227 package facilitates efficient thermal management through direct baseplate cooling. Consider the 700 V rating and 30 A current capacity when designing for industrial or automotive power electronics environments.

Part Context

This device belongs to the Microsemi silicon carbide power Schottky barrier diode product line, now part of Microchip Technology. These components are engineered to replace traditional silicon diodes in high-voltage applications, offering superior performance characteristics and reduced total cost of ownership for demanding power electronic designs.

Replacement Considerations

The datasheet identifies the MSC2X30SDA070J as a related variant featuring an anti-parallel configuration instead of the parallel setup found in the MSC2X31SDA070J. Verify electrical pinout compatibility and thermal requirements when considering alternative manufacturers or different package styles.
