1N1201AR

Single Diodes Overview

The Microchip Technology 1N1201AR is a single standard recovery rectifier diode designed for stud mount applications. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 12 A. The device utilizes a DO-203AA (DO-4) metal case package with one pin. Key electrical characteristics include a maximum forward voltage of 1.2 V at 30 A, a non-repetitive peak forward surge current of 250 A, and a maximum reverse leakage current of 10 µA at 150 V. The junction temperature range spans from -65 °C to +200 °C.

Single Diodes Procurement Notes

Verify the specific suffix 'AR' against official Microchip documentation to confirm exact packaging or material specifications, as generic part numbers may vary. Confirm RoHS compliance status, as historical data indicates some variants are not compliant. Ensure the supplier provides valid traceability documents for the DO-203AA package type.

Single Diodes Selection Notes

Select this component when a 150 V rating and 12 A continuous current capacity are required in a stud-mount configuration. Compare against the 1N1202 series if higher voltage ratings are needed. Verify that the mounting surface and torque specifications align with the DO-4 package requirements for reliable thermal performance.

Single Diodes Part Context

This component belongs to the 1N120x series of high-power rectifiers manufactured by Microchip Technology. These devices are characterized by robust construction suitable for demanding environments. The series typically includes variants with different reverse voltage ratings while maintaining similar current handling capabilities in the same physical package.

Single Diodes Replacement Considerations

Direct substitutes within the same family include the 1N1201 and 1N1201B, provided the voltage and current ratings match the application requirements. Cross-brand replacements must be verified for identical package dimensions and thermal characteristics.
