MURTA30040R

Overview

The MURTA30040R is a silicon super fast recovery diode module manufactured by GeneSiC Semiconductor. It features a common anode configuration with two elements and supports a repetitive peak reverse voltage of 400 V. The device provides an average forward current of 300 A per package, with a maximum instantaneous forward voltage of 1.3 V at 150 A. It withstands a peak forward surge current of 2750 A per leg and exhibits a maximum reverse recovery time of 130 ns. The module operates within a junction temperature range of -55 to 150 °C.

Feature Summary

• Heavy three tower package design for high surge capability
• Electrically isolated base plate construction
• Common anode dual element configuration

Applications

• General purpose rectification in power electronics
• High frequency switching applications requiring fast recovery
• Industrial power conversion systems

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm terminal orientation, as the 'R' designation indicates reversed leads compared to standard variants. Confirm thermal interface requirements and mounting torque specifications prior to installation. Ensure compatibility with existing heatsink designs due to the heavy three tower package dimensions.

Selection Notes

Select this component for applications requiring high current handling and fast reverse recovery characteristics. The 400 V rating suits medium voltage DC circuits. Consider the 130 ns reverse recovery time for efficiency in high-frequency converters. Verify that the 300 A average current rating meets the continuous load requirements of the target circuit design.

Part Context

This module belongs to the MURTA300 series of silicon super fast recovery diodes from GeneSiC Semiconductor. The series spans voltage ratings from 200 V to 400 V, sharing identical current and thermal characteristics. The MURTA30040R represents the highest voltage variant in this specific package family, maintaining consistent performance metrics across the lineup.

Replacement Considerations

Direct substitutes include other MURTA300 series modules with matching electrical ratings. Verify lead orientation differences when replacing non-R variants with R-designated parts. Cross-reference thermal resistance values to ensure adequate cooling solutions are maintained during substitution.
