SE20PAG-M3/I

Single Diodes Overview

The SE20PAG-M3/I is a high-speed silicon rectifier diode from Vishay General Semiconductor, designed for general-purpose applications. It features an axial-leaded DO-201AD (DO-15) package and offers a repetitive peak reverse voltage of 200 V with a maximum average forward rectified current of 20 A at 50°C. The device exhibits a low forward voltage drop of 1.1 V max at rated current and supports a non-repetitive surge current of 300 A. Operating temperatures range from -65°C to +175°C junction temperature.

Single Diodes Feature Summary

• High thermal stability with extended operating junction temperature up to 175°C
• Low forward voltage drop for improved efficiency
• Robust construction in standard axial leaded package

Single Diodes Applications

• General purpose rectification in power supplies
• Freewheeling diodes in inductive load circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the specific suffix 'M3' indicates halogen-free and RoHS compliance status per current Vishay documentation. Confirm 'I' denotes tape-and-reel packaging if bulk supply is required. Cross-reference datasheet revision dates to ensure parameter consistency. Check for any updated environmental declarations or material composition statements before final procurement approval.

Single Diodes Selection Notes

Select this component when 20 A continuous current handling is required alongside 200 V blocking capability. Ensure thermal management strategies account for the 1.1 V forward drop at full load. Verify that the DO-201AD footprint matches the PCB layout constraints. Consider the 175°C junction rating for high-temperature environments where standard 150°C devices may fail.

Single Diodes Part Context

This part belongs to Vishay's SE series of high-current silicon rectifiers. The M3 suffix typically signifies compliance with modern environmental directives. The I suffix often indicates reel packaging for automated assembly. This series is widely used in industrial and consumer electronics requiring reliable high-current rectification.

Single Diodes Replacement Considerations

Direct substitutes include other 20A/200V axial rectifiers from manufacturers like Littelfuse or Diodes Inc., provided pinout and thermal characteristics match. Verify equivalent forward voltage and surge current ratings. Ensure replacement parts meet the same RoHS and halogen-free requirements if specified.
