- Constructed in an axial leaded package to facilitate automated through-hole insertion manufacturing
Applications
- Signal processing in computer systems
- General-purpose rectification in electronic circuits
- Low-power switching applications
Procurement Notes
Verify that the specific suffix /TR indicates tape-and-reel packaging rather than bulk supply when reviewing distributor listings. Confirm the manufacturer part number matches exactly to ensure correct component identification. Check datasheets for RoHS compliance status as specifications may vary by production batch. Validate that the ordering quantity aligns with the manufacturer's minimum reel requirements before finalizing procurement orders.
Selection Notes
Select this component when a small-signal diode with 180 V reverse voltage capability is required for through-hole assemblies. Ensure the application current does not exceed the specified limits for optimal reliability. Consider the axial package dimensions for adequate spacing on the printed circuit board layout. Verify compatibility with existing circuit designs requiring similar switching characteristics and thermal management profiles.
Part Context
This component belongs to the 1N485 series of general-purpose switching diodes manufactured by Microchip Technology. The series offers standardized electrical characteristics for common digital and analog signal applications. The /TR suffix denotes the specific reel packaging configuration used for high-volume automated assembly lines.
Replacement Considerations
Consult official Microchip documentation for verified substitute part numbers. Cross-reference electrical parameters such as peak inverse voltage and forward current when evaluating alternative components from other manufacturers.
