IRKT91/06A

Overview

The IRKT91/06A is a silicon rectifier diode module manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration housed in the ADD-A-PAK (TO-240AA) flange mount package. The device supports a maximum repetitive peak reverse voltage of 600 V and a continuous forward current of 100 A. It withstands a non-repetitive peak forward surge current of 2115 A. The module operates within a junction temperature range of -40 °C to +150 °C.

Feature Summary

• Dual common anode configuration for bridge rectifier applications
• Isolated flange mount design for efficient heat dissipation
• High surge current capability for robust power handling

Applications

• Industrial power supplies
• Inverter circuits
• Motor drive systems

Procurement Notes

Verify the specific suffix 'A' against official Vishay documentation to confirm exact electrical tolerances and marking variations, as suffixes often denote specific manufacturing revisions or testing criteria. Ensure the procurement channel provides original manufacturer packaging to prevent counterfeit components. Cross-reference the datasheet revision date with the production batch to ensure compliance with current RoHS directives and material declarations.

Selection Notes

Select this component for high-current rectification tasks requiring a common anode topology. The TO-240AA package facilitates direct mounting to heatsinks via the isolated base plate. Compare the 600 V rating against system transient voltages to ensure adequate safety margins. Evaluate thermal resistance requirements based on the 100 A continuous current rating and expected ambient operating conditions.

Part Context

This part belongs to the Vishay IRKT series of power diode modules. These modules are designed for general-purpose rectification in industrial environments. The ADD-A-PAK family offers standardized dimensions for easy integration into existing power electronics designs. The series typically includes variants with different voltage ratings to suit various DC link and AC input specifications.

Replacement Considerations

Consult official Vishay substitution guides for verified equivalents. Generic replacements must match the 100 A current rating, 600 V blocking voltage, and TO-240AA mechanical footprint. Verify that alternative parts maintain identical pinout configurations and thermal characteristics to ensure compatibility with existing cooling solutions.
