Single Zener Diodes Procurement Notes

Verify the specific suffix DUR-1/TR against official Microchip documentation to confirm the exact reel packaging configuration and manufacturing lot details. Ensure that the DO-213AA-2 footprint matches the target PCB design constraints. Confirm compliance requirements such as MIL-PRF-19500 standards if applicable to the end-use system. Cross-reference the date code and traceability documents upon receipt to maintain quality assurance protocols.

Single Zener Diodes Selection Notes

Select this component when a 20 V regulation point is required with strict tolerance limits in a surface-mount form factor. The wide temperature capability makes it suitable for military or industrial systems where standard commercial parts would fail. Consider the 150 Ohm impedance value for dynamic load regulation needs. Evaluate the 500 mW power rating against the expected thermal environment to ensure adequate heat dissipation without derating.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JAN designation indicates a military-grade qualification level, ensuring higher reliability and stricter screening compared to commercial variants. The series is widely used in critical systems where component failure is not an option, leveraging established semiconductor processes for long-term availability and performance consistency.
