Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the component was originally produced by Microsemi which was acquired by Microchip Technology. Confirm the presence of the JAN prefix if military-grade specifications are required. Ensure the package type matches the DO-204AL footprint on your PCB design. Check for lead-free compliance status if RoHS regulations apply to your assembly process.

Single Zener Diodes Selection Notes

Select this component when a precise 75 V regulation point is needed with minimal variance. The ±1% tolerance makes it suitable for precision analog circuits. Consider the 1.5 W power rating for thermal management requirements. The DO-41 package is appropriate for standard through-hole manufacturing processes. Evaluate the high-temperature rating against your system's operating environment.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family used for voltage regulation and clamping. Originally manufactured by Microsemi, production continues under Microchip Technology following their acquisition. The 1N4486D is part of a broader series of axial-leaded diodes designed for robust performance in industrial and defense applications.
