1N4437T

Overview

The 1N4437T is a single-phase bridge rectifier manufactured by Microchip Technology. It features a silicon construction with a maximum repetitive peak reverse voltage of 400 V and an average rectified output current of 10 A. The device supports a non-repetitive peak forward surge current of 100 A and exhibits a maximum forward voltage of 1.2 V at 10 A. It operates within a temperature range of -65°C to +160°C and utilizes a press-fit package configuration.

Feature Summary

• Single-phase bridge rectifier configuration
• Hermetic sealed package design
• High thermal stability operation

Applications

• Industrial power supply systems
• Military electronic equipment
• Aerospace power conversion units

Procurement Notes

Verify the specific datasheet version for the 1N4437T to confirm exact mechanical dimensions and electrical tolerances. Ensure compatibility with high-temperature environments due to the specified operating range. Confirm that the press-fit mounting method aligns with the target PCB or chassis design requirements before finalizing procurement.

Selection Notes

Select this component when a hermetically sealed, high-reliability bridge rectifier is required for harsh environments. The 10 A current rating and 400 V reverse voltage suit moderate-power applications. Consider the press-fit package for vibration-resistant installations where traditional soldering may be insufficient.
