1N3263R

Single Diodes Overview

The 1N3263R is a general-purpose stud-mounted silicon rectifier diode manufactured by Microchip Technology (formerly Powerex). It features a glass passivated die and glass-to-metal seal construction for robust performance. The device is rated for a maximum repetitive peak reverse voltage of 200V and an average rectified forward current of 160A. It exhibits soft recovery characteristics and high surge current capability, making it suitable for industrial power applications requiring reliable unidirectional current flow.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Soft recovery characteristic to minimize switching noise
• High surge current capability for transient protection
• Stud mount package design for efficient thermal management

Single Diodes Applications

• Industrial power conversion systems
• General purpose rectification in AC-DC converters
• Inverter and chopper circuits
• Welding equipment power stages

Single Diodes Procurement Notes

Verify the manufacturer origin, as the 1N3263R designation is used by multiple entities including Powerex, Microsemi, and others. Confirm RoHS compliance status with the specific supplier, as historical versions may differ. Ensure the stud mounting interface matches your heatsink requirements. Request official datasheets from the specific vendor to confirm electrical tolerances and pinout configurations before integration.

Single Diodes Selection Notes

Select this component when a high-current, low-voltage rectifier with stud mounting is required. The 200V rating limits its use to low-voltage AC lines or secondary sides of transformers. Consider thermal resistance and mounting torque specifications for proper heat dissipation. Compare surge current ratings against expected load transients to ensure adequate safety margins during startup or fault conditions.

Single Diodes Part Context

This part belongs to the standard rectifier diode family, historically associated with GE and later Powerex/Microsemi. It is a through-hole stud-mount device designed for high-power discrete semiconductor applications. The 1N3263R serves as a legacy replacement for older GE-specified components in industrial control and power supply designs.

Single Diodes Replacement Considerations

Direct substitutes include parts from the same 1N3263 series such as 1N3263AR or 1N3263RA, provided voltage and current ratings match. Verify that alternative stud diodes offer comparable thermal resistance and mechanical mounting dimensions to ensure compatibility with existing heatsink infrastructure.
