Single Zener Diodes Procurement Notes

Verify the specific suffix CUS/TR against official Microchip documentation to confirm the exact package type and tape-and-reel packaging configuration. Ensure the component meets MIL-PRF-19500 qualification requirements for your intended application. Cross-reference datasheet parameters such as Zener impedance and leakage current with your design specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 75 V regulation point is required in a surface-mount form factor. The ±2% tolerance offers higher precision than standard commercial variants. Consider the 5 W power dissipation capability and wide temperature range for harsh environment deployments. Verify that the D-5B-2 footprint matches your PCB layout constraints.

Single Zener Diodes Part Context
