Single Zener Diodes Procurement Notes

Verify the specific suffix E3 for RoHS compliance and TR13 for tape-and-reel packaging configuration. Confirm availability status as discontinuation notices may apply to this family. Ensure the 91 V rating matches the target circuit requirements before integration. Cross-reference the DO-214AA footprint dimensions with PCB design libraries.

Single Zener Diodes Selection Notes

Select this component when a 91 V Zener voltage is required in a compact SMB package. Consider the 2 W power rating for thermal management in the application environment. Verify that the ±10% tolerance aligns with the precision needs of the voltage regulation task. Check compatibility with automated pick-and-place processes due to the reel packaging.
