Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm it denotes the ±1% tolerance variant rather than standard commercial grade. Confirm RoHS compliance status as historical data indicates non-compliance for some variants in this series. Ensure the DO-35 package matches your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when strict voltage stability over temperature is required compared to standard Zener diodes. The ±1% tolerance offers higher precision than typical 5% or 10% devices. Consider the DO-35 package size constraints and the need for through-hole mounting technology during circuit board layout planning.
