1N2281

Single Diodes Overview

The Microchip Technology 1N2281 is a high-voltage, high-current standard recovery rectifier designed for demanding power conversion applications. It features a reverse voltage rating of 600 V and supports an average forward current of 12 A within the DO-203AA-2 (TO-5) stud mount package. The device exhibits a maximum forward voltage drop of 1.2 V at rated current and withstands surge currents up to 250 A. Operating reliably across a temperature range from -65 °C to +200 °C junction temperature, it ensures robust performance in harsh environments with low leakage current specifications.

Single Diodes Feature Summary

• Engineered for high-temperature stability with a maximum operating junction temperature of 200 °C
• Capable of handling significant electrical stress through a 250 A non-repetitive peak forward surge current rating
• Provides reliable high-voltage isolation with a 600 V repetitive peak reverse voltage capability

Single Diodes Applications

• High-power industrial motor drives
• Heavy-duty welding equipment

Single Diodes Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact thermal and mechanical tolerances. Confirm stud mounting requirements and torque specifications prior to integration. Ensure compatibility with existing heat sink interfaces and verify that the DO-203AA-2 footprint matches the target PCB or chassis design constraints.

Single Diodes Selection Notes

Select this component when applications require extreme thermal resilience exceeding standard silicon limits. The 12 A continuous current rating suits medium-to-high power density designs. Evaluate the 1.2 V forward voltage drop against system efficiency targets. Consider the stud mount configuration for effective thermal dissipation in enclosed or high-load scenarios.
