Overview
The Microchip Technology 1N4248US/TR is a single rectifying diode designed for surface-mount applications. It features an Ultra Fast Recovery (UFR) and Fast Reverse Recovery (FRR) characteristic, making it suitable for high-speed switching circuits. The device is housed in a small outline (SQ) package and supplied in tape and reel format. Key electrical specifications include a maximum repetitive peak reverse voltage of 800V and an average forward rectified current rating of 1A.
Feature Summary
- Ultra fast and fast reverse recovery characteristics for efficient high-frequency operation
- Surface-mount SQ package design for automated assembly processes
- High voltage blocking capability suitable for demanding power applications
Applications
- High-speed switching power supplies
- Freewheeling diodes in inductive load circuits
- General purpose rectification in consumer electronics
Procurement Notes
Verify the specific datasheet revision to confirm exact thermal resistance values and absolute maximum ratings. Ensure the SQ package footprint matches the target PCB layout. Confirm RoHS compliance status as indicated in official documentation, noting that some listings may indicate non-compliance. Validate the tape and reel quantity against manufacturing requirements.
Selection Notes
Select this component when ultra-fast recovery times are critical to minimize switching losses. The 800V rating provides significant headroom for high-voltage AC line applications. Compare the SQ package dimensions against available board space constraints. Consider the 1A current rating relative to the expected thermal environment and heat dissipation capabilities of the final assembly.
Part Context
This part belongs to Microchip's discrete diode portfolio, specifically within the rectifier category. It complements through-hole variants like the 1N4248 by offering a compact surface-mount alternative. The US suffix typically denotes the specific plastic encapsulation type used for surface-mount technology integration.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source material. Verify pinout compatibility and electrical parameters before considering any generic equivalents.
