1N3292A

Single Diodes Overview

The Powerex Inc. 1N3292A is a high-power rectifier diode designed for demanding industrial applications. It features a single element configuration with a maximum average forward rectified current of 150 A and a repetitive peak reverse voltage rating of 500 V. The device supports a non-repetitive peak forward surge current of 2500 A, ensuring robust performance under transient conditions. It exhibits a maximum forward voltage drop of 1.1 V at rated current and operates reliably up to a junction temperature of 200 °C. This component utilizes a stud mount package for efficient thermal dissipation in high-current circuits.

Single Diodes Feature Summary

• High thermal stability enabling operation at elevated junction temperatures up to 200 °C
• Robust surge current handling capability for protection against transient overloads
• Low forward voltage drop characteristics for improved energy efficiency
• Durable stud mount construction optimized for effective heat sinking

Single Diodes Applications

• Industrial motor drives and variable frequency drive rectification
• DC power supply input stages requiring high current capacity
• Welding equipment power conversion systems
• Battery charging systems for heavy-duty machinery

Single Diodes Procurement Notes

Verify the specific suffix code on the component marking to confirm exact electrical tolerances and terminal plating specifications. Confirm that the mounting hardware matches the stud dimensions and thread pitch required by your heatsink assembly. Ensure the operating environment allows for adequate airflow or liquid cooling to maintain the junction temperature within the specified 200 °C limit during continuous load cycles.

Single Diodes Selection Notes

Select this component when circuit designs demand high current handling exceeding standard discrete diode capabilities. Evaluate the thermal resistance of the proposed mounting interface to ensure the 200 °C junction limit is not exceeded under worst-case ambient conditions. Consider the 500 V reverse voltage rating relative to the system's peak line voltages and transient spikes to guarantee long-term reliability without breakdown.

Single Diodes Part Context

This part belongs to the general category of high-power silicon rectifiers manufactured by Powerex Inc., now part of IXYS Corporation. These devices are engineered for rugged environments where standard surface-mount components cannot dissipate heat effectively. The 1N3292A represents a legacy numbering convention often used in industrial power electronics for standardized replacement across various equipment generations.

Single Diodes Replacement Considerations

Consult official cross-reference lists from IXYS/Powerex for direct replacements. Verify that any substitute maintains the 150 A current rating, 500 V blocking voltage, and compatible stud mounting dimensions to fit existing mechanical assemblies without modification.
