Procurement Notes
Verify the specific suffix /TR indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct electrical characteristics and physical dimensions. Check for any recent product change notices regarding assembly sites or labeling updates before finalizing procurement plans.
Selection Notes
Select this component when a fixed current source is required without complex circuitry. Ensure the load voltage does not exceed the 100V maximum limit. Verify that the 475mW power dissipation capability is sufficient for the operating conditions and ambient temperature constraints of the target application.
Part Context
This part belongs to the 1N5283-1N5314 series of current regulator diodes manufactured by Microchip Technology. These devices are widely used for their simplicity and stability in providing reference currents. The 1N5299 variant specifically offers a 1.32mA output, fitting into the standardized numbering system for these regulators.
Replacement Considerations
Cross-reference with other 1.32mA current regulator diodes from different manufacturers if supply is constrained. Ensure equivalent voltage ratings, power dissipation, and package compatibility. Verify that alternative parts meet the same temperature range requirements for seamless integration.
