Procurement Notes

Verify the specific ordering suffix and manufacturer lot codes against official Microchip documentation to ensure authenticity. Confirm that the component meets required environmental standards such as RoHS or REACH compliance before integration into final assemblies. Cross-reference datasheet revisions to account for any recent manufacturing changes.

Selection Notes

Select this component when a fixed low-current regulation value near 1.65mA is required. Ensure the circuit design accommodates the 100V peak voltage limit and 475mW power dissipation constraints. Verify that the axial through-hole package fits the available PCB real estate and thermal management requirements of the target application.

Part Context

The 1N5302 belongs to the 1N5283-1N5314 series of current regulator diodes manufactured by Microchip Technology. This series offers various regulated current values to suit different circuit needs while maintaining similar voltage and power characteristics.
