Single Zener Diodes Procurement Notes

Verify that the ordering suffix HE3 confirms AEC-Q101 qualification and RoHS compliance as specified in the datasheet. Ensure the base quantity matches the required delivery mode for the specific suffix variant. Confirm the component meets JESD 201 class 2 whisker test requirements before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when an AEC-Q101 qualified Zener diode is required for automotive or high-reliability circuits. The 12 V nominal rating and 1.5 W power dissipation capability make it suitable for robust voltage regulation tasks. Verify that the SMBG package dimensions align with the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the SMZG3788B through SMZG3809B series of surface-mount power voltage-regulating diodes. The series covers a wide Zener voltage range from 9.1 V to 68 V. All variants share the same SMBG (DO-215AA) package profile and utilize glass passivation for the chip junction to ensure reliability.
