Procurement Notes
Verify the specific suffix designation against official datasheets to confirm package type and tape-and-reel specifications. Ensure the component meets required RoHS compliance status for the target assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a 70 V reverse voltage rating and 100 mA continuous current capacity are required. Consider the DO-35-2 package dimensions for spatial constraints. Evaluate the 1 V forward voltage drop against efficiency requirements. Confirm that the 2 A surge current capability aligns with expected transient loads in the circuit design.
Part Context
This diode belongs to the 1N483 series of small-signal rectifiers manufactured by Microchip Technology. The series offers various voltage ratings within the same physical footprint. It serves as a fundamental discrete semiconductor component for low-power electronic systems. The product line emphasizes reliability for industrial and computing environments.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching electrical parameters. Verify pinout compatibility and package dimensions before implementing any alternative components.
