Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment requirements for the DO-213AA-2 footprint. Confirm moisture sensitivity level handling procedures prior to assembly to maintain component integrity during soldering processes.
Selection Notes
Select this component when a surface mount solution is required for high-voltage switching tasks. The 175 V rating provides headroom for transient protection scenarios. Compare performance metrics against through-hole alternatives if board space constraints dictate the use of compact SMD packages like DO-213AA-2.
Part Context
This part belongs to the 1N4938 series of general-purpose silicon switching diodes manufactured by Microchip Technology. The series offers robust performance for standard rectification and switching duties. The UR-1 designation typically indicates a specific surface mount variant within the broader product family.
Replacement Considerations
Cross-reference with other 1N4938 variants from different manufacturers ensuring identical DO-213AA-2 packaging and matching electrical parameters such as 175 V PIV and 100 mA IF.
