1N2458

Single Diodes Overview

The 1N2458 is a silicon power rectifier manufactured by Microchip Technology. It features a stud mount configuration within the DO-5 (DO-203AB) package. The device is designed for high-current applications, offering a surge rating of 1050 Amps and a maximum repetitive reverse voltage (VRRM) up to 1600V. Key electrical characteristics include low forward voltage drop and glass passivated die construction with glass-to-metal voltage isolation.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Stud mount design suitable for high-power thermal management
• Low forward voltage characteristic for efficiency
• High surge current capability

Single Diodes Applications

• Industrial power supplies
• Motor drive rectification
• High-voltage DC conversion systems

Single Diodes Procurement Notes

Verify the manufacturer origin, as the component was originally associated with Microsemi Corporation before its acquisition by Microchip Technology. Confirm the specific VRRM rating required for your application, as datasheets indicate a range up to 1600V. Ensure the DO-5 stud mount package matches your thermal and mechanical constraints. Request the official datasheet from Microchip or authorized distributors to validate exact electrical parameters for the specific voltage variant being procured.

Single Diodes Selection Notes

Select this component when high surge current handling and robust packaging are required. The stud mount option facilitates direct heatsinking, making it suitable for environments where standard leaded packages may fail thermally. Consider the specific reverse voltage rating needed, as the 1N2458 designation covers a range up to 1600V. Evaluate the low forward voltage benefit against system efficiency requirements compared to other rectifier technologies.

Single Diodes Part Context

The 1N2458 belongs to the family of general-purpose silicon power rectifiers produced by Microchip Technology. Historically, these parts were distributed under the Microsemi brand prior to corporate integration. The series is characterized by rugged construction and high current capabilities, serving as a bridge between standard signal diodes and specialized high-power modules in industrial electronics.

Single Diodes Replacement Considerations

Check for equivalent stud-mount rectifiers from other manufacturers if Microchip stock is unavailable. Verify that any substitute matches the DO-5 package dimensions and thermal resistance characteristics. Ensure the replacement part meets or exceeds the 1050A surge rating and the specific reverse voltage requirement of the original circuit design.
