Procurement Notes

Verify the specific manufacturer source, as CDI-DIODE datasheets reference this part number under Microchip branding. Confirm RoHS compliance status, as some distributor listings indicate non-compliance. Check for active production status versus obsolete or discontinued classifications from official Microchip channels before procurement planning.

Selection Notes

Select this component when a hermetically sealed surface mount Schottky rectifier is required for high-reliability designs. Ensure the 30 V reverse voltage rating meets circuit requirements. Verify that the SQ-MELF footprint matches the PCB layout constraints. Consider thermal derating guidelines for operation above 55°C ambient conditions.

Part Context

This part belongs to the 1N582x series of Schottky barrier rectifiers manufactured by Microchip Technology. The series includes variants such as 1N5820US and 1N5822US, differentiated primarily by their peak reverse voltage ratings.
