MSRTA300140D

Overview

The MSRTA300140D is a silicon standard recovery diode module manufactured by GeneSiC Semiconductor. It features a heavy three tower package with an electrically isolated base plate. The device supports a repetitive peak reverse voltage of 1400 V and a DC blocking voltage of 1400 V. Each leg provides an average forward current rating of 300 A at a case temperature of 125 °C. The maximum instantaneous forward voltage is 1.1 V per leg, while the maximum thermal resistance from junction to case is 0.28 °C/W. The operating temperature range spans from -55 °C to 150 °C.

Feature Summary

• Heavy three tower package design for high surge capability
• Electrically isolated base plate configuration
• Standard silicon recovery technology

Applications

• Industrial power conversion systems
• High voltage rectification circuits
• Motor drive applications

Procurement Notes

Verify the specific voltage rating suffix against official datasheets, as the MSRTA300 series includes variants ranging from 1200 V to 1600 V. Confirm the manufacturer designation, as some listings may reference Navitas Semiconductor due to corporate acquisitions. Ensure the component matches the required electrical isolation and thermal resistance specifications for your application.

Selection Notes

Select this module when high surge current handling and electrical isolation are required in a compact form factor. The 300 A current rating suits medium-to-high power industrial applications. Consider the 0.28 °C/W thermal resistance for heatsink design. Verify that the 1400 V reverse voltage meets the circuit's peak inverse voltage requirements.

Part Context

This component belongs to the MSRTA300XXXD series, which encompasses standard recovery diodes with ratings from 1200 V to 1600 V. The series utilizes a consistent heavy three tower package structure across all voltage variants. The 'D' suffix typically denotes the standard recovery type within this product family.

Replacement Considerations

Direct substitutes include other MSRTA300XXXD models with matching voltage ratings, such as MSRTA300120D or MSRTA300160D, provided the reverse voltage requirements align. Cross-brand replacements must match the 300 A current, 1400 V rating, and three tower package dimensions.
