IRKD166/12

Diode Arrays Overview

The IRKD166/12 is a high-voltage power diode module manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the INT-A-PAK package and features a common anode configuration with two silicon elements. The device supports a maximum repetitive reverse voltage of 1200 V and an average rectified forward current of 165 A per diode. It operates within a junction temperature range of -40°C to +150°C and includes an electrically isolated base plate for simplified thermal management.

Diode Arrays Feature Summary

• Electrically isolated metal base plate allows for direct mounting to common heatsinks without additional insulators.
• High surge capability designed to withstand non-repetitive peak forward currents up to 3500 A.
• Industrial standard INT-A-PAK package facilitates rapid assembly and simplified mechanical design.

Diode Arrays Applications

• High voltage power conversion systems
• Freewheeling applications in industrial inverters
• Construction of single-phase or three-phase bridge rectifiers

Diode Arrays Procurement Notes

Verify the specific voltage suffix (e.g., /08, /12, /16) against the required circuit voltage rating, as the IRKD166 series offers multiple variants with identical current ratings but different blocking voltages. Confirm RoHS compliance status and packaging type directly with the manufacturer or authorized distributors, as availability and lead times vary by region and production batch.

Diode Arrays Selection Notes

Select this component when designing circuits requiring high voltage isolation and robust surge handling capabilities. Ensure the heatsink interface matches the INT-A-PAK footprint and that the thermal resistance calculations account for the isolated base plate characteristics. Verify that the operating frequency aligns with the standard recovery time specifications to minimize switching losses.

Diode Arrays Part Context

This module belongs to the IRKJ/IRKD series of INT-A-PAK power diodes from Vishay. These modules are engineered for high-power industrial applications where electrical isolation between the semiconductor junction and the cooling system is critical. The series provides reliable performance in demanding environments through standardized packaging and high surge ratings.

Diode Arrays Replacement Considerations

Cross-reference with Vishay part numbers such as VS-VSKJ166/12PBF or International Rectifier equivalents like IRKJ166-12PBF. Ensure any substitute maintains the same 1200 V rating, 165 A current capacity, and INT-A-PAK mechanical dimensions for direct compatibility.
