1N1201A

Single Diodes Overview

The Microchip Technology 1N1201A is a single standard recovery silicon rectifier diode housed in the DO-203AA (DO-4) stud mount package. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current rating of 12 A at 85°C. The device exhibits a maximum DC forward voltage drop of 1.35 V at 12 A and a non-repetitive peak forward surge current capability of 240 A. Operating temperatures range from -60°C to +200°C junction temperature, with a maximum reverse leakage current of 2.25 mA.

Single Diodes Feature Summary

• Robust surge current handling capability for power circuit protection
• Extended high-temperature operation up to 200°C junction temperature

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the manufacturer source carefully, as the 1N1201A designation is historically associated with multiple vendors including Vishay and International Rectifier. Ensure the specific datasheet provided matches the Microchip Technology part number requirements. Confirm package integrity and marking accuracy upon receipt to distinguish between original and potential substitute components.

Single Diodes Selection Notes

Select this component when a robust, stud-mountable rectifier is required for medium-power applications. The 12 A current rating and 150 V blocking voltage define its operational limits. Consider the thermal management requirements inherent to the DO-203AA package style for proper heat dissipation in the final assembly.

Single Diodes Part Context

The 1N1201A belongs to the legacy 1N series of general-purpose silicon rectifiers. Originally standardized by JEDEC, these parts are widely used in industrial and automotive electronics. Microchip Technology continues to support this form factor for compatibility with existing designs requiring stud-mounted configurations.

Single Diodes Replacement Considerations

Direct substitutes include Vishay VS-1N1201A and International Rectifier equivalents sharing identical electrical ratings and DO-203AA packaging. Verify pinout compatibility and thermal resistance specifications before substitution.
