1N3290AR

Single Diodes Overview

The Microchip Technology 1N3290AR is a silicon power rectifier diode housed in the DO-205AA (DO-8) metal stud package. It features a maximum average forward current of 100 A and a repetitive peak reverse voltage rating of 300 V. The device supports a non-repetitive peak forward surge current of 2300 A. Designed for high-power applications, it utilizes a single-element configuration with an anode-connected case for efficient heat dissipation.

Single Diodes Feature Summary

• High-current capability with 100 A average forward current rating
• Robust surge handling with 2300 A non-repetitive peak forward surge capacity
• Metal stud mounting design for effective thermal management
• Anode-connected case structure for simplified circuit integration

Single Diodes Applications

• Industrial power supplies
• Motor drive rectification
• General purpose high-power rectification

Single Diodes Procurement Notes

Verify the manufacturer source carefully, as this component is produced by multiple vendors including Microchip, Powerex, and Digitron under the same part number. Confirm the specific datasheet version and electrical tolerances match your design requirements. Ensure the DO-205AA package dimensions are compatible with your thermal interface and mounting hardware specifications before procurement.

Single Diodes Selection Notes

Select this component when a standard recovery silicon rectifier is required for circuits operating at 300 V reverse bias and up to 100 A continuous current. The DO-205AA package is suitable for board-level or chassis-mount applications where stud mounting facilitates heat sinking. Consider the 2300 A surge rating for systems with high inrush currents.

Single Diodes Part Context

The 1N3290 series represents a family of high-power silicon rectifiers widely used in industrial electronics. The 'R' suffix typically denotes a specific variant within the series, often associated with manufacturers like Microchip or Powerex. These devices are standardized under JEDEC DO-205AA packaging, ensuring interchangeability across different suppliers for general-purpose rectification tasks.

Single Diodes Replacement Considerations

Direct substitutes include the 1N3290A and 1N3290 from various manufacturers such as Digitron and Infineon. Verify that replacement parts maintain the 100 A current and 300 V voltage ratings. Ensure the alternative component uses the same DO-205AA metal stud package for mechanical compatibility.
