1N4248/TR

Overview

The Microchip Technology 1N4248/TR is a military-qualified standard recovery rectifier diode designed for high-reliability applications. It features an 800V maximum repetitive peak reverse voltage and a 1A average forward rectified current rating. The device supports a surge current of 25A and exhibits a maximum forward voltage drop of 1.3V at rated current. Packaged in the A-Axial through-hole format, this component is supplied in tape and reel packaging to facilitate automated assembly processes.

Feature Summary

Military qualification compliant with MIL-PRF-19500/286 standards
Standard recovery characteristics suitable for general-purpose rectification
Through-hole axial package configuration for robust mounting

Applications

High-reliability aerospace systems
Military electronic equipment
Critical power supply rectification circuits

Procurement Notes

Verify that the specific part number includes the /TR suffix to confirm tape and reel packaging, as the base 1N4248 may be obsolete or available in bulk. Confirm military qualification requirements against the latest manufacturer datasheet. Ensure compatibility with automated placement equipment specifications for the axial lead form factor.

Selection Notes

Select this component when military-grade reliability and standard recovery speed are required for high-voltage rectification. The 800V rating distinguishes it from lower-voltage general-purpose diodes. Consider the axial package constraints for board layout and thermal management compared to surface-mount alternatives.

Part Context

This part belongs to the 1N4248 series of standard recovery rectifiers manufactured by Microchip Technology. The series is historically significant for its use in critical defense and aerospace electronics. The /TR designation specifically indicates the reel packaging variant, differing from the standard bulk-packaged 1N4248 which is noted as obsolete.
