Single Zener Diodes Procurement Notes

Verify the authenticity of the component through authorized MCC distributors or direct procurement channels to ensure traceability and quality. Confirm that the ordering suffix matches the required tape and reel packaging specifications. Ensure the application environment remains within the specified operating junction temperature limits to maintain performance integrity.

Single Zener Diodes Selection Notes

Select this component when a 22V reference is required in a compact SMB footprint. Consider the 2W power dissipation capability and the specific dynamic impedance characteristics for precision regulation needs. Verify compatibility with automated surface mount assembly processes given the DO-214AA form factor.

Single Zener Diodes Part Context

This part belongs to the SMB2EZ series of 2W Zener diodes from Micro Commercial Components. The series covers nominal voltages from 10V to 75V, all sharing identical physical dimensions and thermal characteristics. The HE3 designation indicates lead-free finish and RoHS compliance, while the TP suffix specifies tape and reel packaging.

Single Zener Diodes Replacement Considerations

Substitute only with other SMB2EZ22D5HE3-TP units from MCC. Cross-brand replacements require verification of matching voltage tolerance, package dimensions, and thermal ratings.
