Procurement Notes
Verify the specific suffix 'U/TR' against official Microchip documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure compatibility with required thermal management solutions given the wide operating temperature range. Confirm that the 440V reverse voltage rating aligns with the target circuit's peak inverse voltage requirements.
Selection Notes
Select this component when surface-mount installation is required alongside high-speed recovery needs. The 2 A forward current rating suits moderate power applications. Verify that the 45 ns recovery time meets the specific frequency constraints of the design. Consider the -65 °C to +150 °C range for harsh environment suitability.
Part Context
This part belongs to the 1N6621 series of ultra-fast recovery rectifiers manufactured by Microchip Technology. It serves as a semiconductor solution for converting alternating current to direct current in compact electronic assemblies. The device integrates robust junction capabilities to handle transient voltage spikes common in switching power supplies.
Replacement Considerations
Consult official Microchip substitution guides for verified equivalents. Cross-reference parameters such as 440 V reverse voltage, 2 A forward current, and 45 ns recovery time to ensure functional compatibility without altering circuit performance.
