1N3290A

Single Diodes Overview

The Powerex Inc. 1N3290A is a single-element silicon rectifier diode designed for general-purpose applications. It features a maximum repetitive peak reverse voltage of 300 V and an average forward current rating of 100 A. The device utilizes a DO-205AA (DO-8) package with chassis stud mounting, where the case serves as the anode connection. Key electrical specifications include a maximum non-repetitive peak forward surge current of 2300 A and a typical forward voltage drop of 1.5 V at 100 A. The component operates within a junction temperature range of -65°C to 175°C.

Single Diodes Feature Summary

• High-current capability with a 100 A average forward current rating
• Robust surge handling with a 2300 A non-repetitive peak forward current capacity
• Chassis stud mount configuration with case-connected anode for efficient thermal management

Single Diodes Applications

• General-purpose rectification in industrial power supplies
• AC to DC conversion circuits requiring high current handling
• Battery charging systems and motor drive rectifiers

Single Diodes Procurement Notes

Verify that the specific order matches the 1N3290A designation, as suffixes may indicate variations. Confirm mechanical compatibility with existing heatsink or mounting hardware due to the DO-205AA stud format. Ensure thermal interface materials are suitable for the specified operating temperature range. Cross-reference datasheets from authorized distributors to confirm RoHS compliance status and lead times before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when a standard silicon rectifier with 300 V blocking capability and 100 A continuous current is required. The DO-205AA package is suitable for chassis-mounted designs where direct thermal conduction is necessary. Consider the 1.5 V forward voltage drop for efficiency calculations in low-voltage, high-current output stages. Verify that the application does not exceed the 2300 A surge limit during transient events.

Single Diodes Part Context

The 1N3290A belongs to the 1N32xx series of high-power rectifier diodes manufactured by Powerex Inc. This series typically includes variants with different voltage ratings while maintaining similar current capabilities and package styles. These components are engineered for rugged industrial environments, offering reliable performance in demanding power electronics applications where durability and thermal stability are critical.

Single Diodes Replacement Considerations

Direct substitutes must match the 300 V reverse voltage, 100 A current rating, and DO-205AA package. Verify pinout compatibility, noting the case-anode configuration. Check forward voltage characteristics to ensure equivalent thermal performance. Consult manufacturer cross-reference lists for approved equivalents.
