Single Zener Diodes Procurement Notes

Verify the specific suffix TR against official Microchip documentation to confirm tape-and-reel packaging configuration. Ensure the DO-213AB footprint matches your PCB design constraints. Cross-reference the 16 V Zener voltage and 500 mW power rating with your circuit requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 16 V regulation point is required in a surface-mount layout. The DO-213AB form factor suits space-constrained designs. Confirm that the 21 ohm impedance and 500 nA leakage meet your noise and efficiency specifications. Validate thermal management capabilities for the 500 mW dissipation limit in your enclosure.
