Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm the exact package variant and reel packaging specifications. Ensure the requested quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the datasheet revision date to confirm compliance with current manufacturing standards and material declarations before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 6.2 V reference is required under significant thermal stress. The DO-213AA-2 package suits surface-mount designs needing compact footprints. Compare the 500 mW power dissipation limit against circuit load requirements. Verify that the 10 ohm impedance meets the noise and regulation sensitivity constraints of the target application design.

Single Zener Diodes Part Context

This part belongs to Microchip's specialized line of temperature-compensated Zener diodes.
