Single Zener Diodes Procurement Notes

Verify that the ordering suffix HE3 confirms AEC-Q101 qualification and RoHS compliance. Confirm the delivery mode matches the required reel diameter and base quantity. Ensure the component meets the specific environmental requirements for the target application before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when an AEC-Q101 qualified Zener diode is required in the SMBG package. The 15 V nominal voltage and 1500 mW power rating define its operational limits. Verify that the 9 Ω maximum impedance fits the circuit's regulation requirements.

Single Zener Diodes Part Context

This part belongs to the SMZG3788B thru SMZG3809B series of surface-mount power voltage-regulating diodes. The HE3 suffix indicates it is halogen-free, RoHS compliant, and qualified to AEC-Q101 standards. The standard industrial grade version uses the E3 suffix without automotive qualification.
