1N3663R

Single Diodes Overview

The Microchip Technology 1N3663R is a silicon rectifier diode designed for high-current applications. It features a press-fit termination style, formerly designated as DO-21, and is housed in the DO-208AA package. The device supports a repetitive peak reverse voltage of 400V and an average forward current rating of 30A to 35A depending on the specific datasheet source. It includes a maximum non-repetitive surge current capability of 78A at 100°C test conditions.

Single Diodes Feature Summary

• Utilizes press-fit termination technology for secure mechanical mounting without soldering
• Constructed from silicon material for robust rectification performance
• Designed for single-phase, one-element power conversion applications

Single Diodes Applications

• Industrial power supply rectification
• High-current DC power distribution systems
• Heavy-duty electronic equipment requiring press-fit assembly

Single Diodes Procurement Notes

Verify the manufacturer origin, as sources indicate both Microchip Technology and Motorola Inc. production history. Confirm RoHS compliance status, as some listings specify Yes while others note non-rohs. Ensure the package designation matches requirements, noting the transition from DO-21 to DO-208AA descriptions across different distributor catalogs.

Single Diodes Selection Notes

Select this component when press-fit mounting is required for vibration resistance. Compare the 30A versus 35A current ratings against thermal management capabilities. Verify the 400V reverse voltage requirement aligns with circuit peak inverse voltage limits. Consider the physical dimensions of 0.50 x 0.50 x 0.55 inches for board space planning.

Single Diodes Part Context

This part belongs to the standard rectifier diode category within Microchip's discrete semiconductor portfolio. It serves as a replacement for legacy components like the 1N3663R from other manufacturers. The device represents a bridge between traditional through-hole specifications and modern press-fit industrial standards.

Single Diodes Replacement Considerations

The AW1000 item from Aftermarket IR Industrial Controls is listed as a replacement for 1N3663R. Verify electrical equivalence before substitution.
