IRKU91/16A

Overview

The IRKU91/16A is a thyristor/thyristor module from the IRKU/V71, 91 series manufactured by Vishay. It features an average on-state current of 95 A at 85°C and supports repetitive peak reverse voltages up to 1600 V. The device utilizes an ADD-A-pak Gen V package with a thick copper baseplate for thermal management. Key electrical ratings include a maximum RMS on-state current of 150 A and a non-repetitive peak surge current of 1785 A at 50 Hz. The junction temperature range spans from -40°C to 125°C.

Feature Summary

High voltage industrial standard package with up to 1600V capability
Thick copper baseplate combined with Al2O3 DBC insulator for superior thermal performance
UL E78996 approved with 3500 VRMS isolating voltage
Mechanically rugged design without hard mold to eliminate stress on leads

Applications

High voltage regulated power supplies
Lighting circuits
Temperature control circuits
Motor speed control circuits
UPS systems and battery chargers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's bulletin I27135. Confirm that the dv/dt rating matches the application requirements, as standard versions operate at 500 V/µs while S90 variants provide 1000 V/µs. Ensure the selected part number corresponds to the correct circuit configuration and current code within the IRKU/V71, 91 series specifications.

Selection Notes

Select this component based on the required average on-state current and blocking voltage levels. Consider the thermal resistance characteristics and mounting torque specifications for proper heatsink integration. Evaluate the surge current capabilities relative to the expected fault conditions in the circuit design.

Part Context

This module belongs to the IRK.71 and IRK.91 series of thyristor/thyristor power modules. These devices are designed for general purpose high voltage applications requiring robust mechanical construction and efficient heat dissipation through a grounded heatsink interface.

Replacement Considerations

Consult official documentation for direct substitutes. Verify compatibility regarding package dimensions, pinout configurations, and electrical ratings before implementation.

FAQ

What is the maximum repetitive peak off-state voltage?

The maximum repetitive peak off-state voltage (VRRM) ranges from 400 V to 1600 V depending on the specific voltage code.

How does the package design improve thermal performance?

The Generation V Add-A-pak module uses a Direct Bonded Copper substrate and a solid copper baseplate to enhance thermal spread and mounting tolerance.
