MSRTA30080AD

Overview

The MSRTA30080AD is a silicon standard recovery diode module from the MSRTA300 series, rated for a repetitive peak reverse voltage of 800 V and an average forward current of 300 A per leg. It features a heavy three tower package with an electrically isolated base plate. The maximum instantaneous forward voltage is 1.1 V at Tj = 25 °C, while the maximum thermal resistance from junction to case is 0.28 °C/W. The device operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Heavy three tower package design providing high surge capability
• Electrically isolated base plate construction
• Standard silicon recovery characteristics

Applications

• Industrial power supplies
• Inverter circuits
• DC-DC conversion systems

Procurement Notes

Verify the specific voltage rating suffix against the datasheet table, as the MSRTA300 series spans multiple ratings. Confirm the package type matches the required isolation specifications. Check for any obsolescence notices or lifecycle status updates prior to finalizing procurement plans.

Selection Notes

Select this component when an electrically isolated base plate is required for high-current applications. Ensure the thermal management system can handle the specified junction-to-case thermal resistance. Verify that the 800 V blocking voltage aligns with the circuit's peak reverse voltage requirements.

Part Context

This module belongs to the MSRTA300 family of silicon rectifier modules. The series includes variants ranging from 600 V to 1000 V, all sharing the same 300 A current rating and heavy three tower package structure. The 'AD' suffix typically denotes specific terminal configurations or packaging variations within this product line.

Replacement Considerations

Direct replacements include other MSRTA300XXD models with matching voltage ratings. Cross-reference pinouts and thermal resistance values when substituting with modules from different manufacturers.
