Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the ordering suffix indicates RoHS compliance. Ensure storage conditions align with Moisture Sensitivity Level 1 requirements prior to soldering. Check datasheet specifications against application thermal constraints.

Single Zener Diodes Selection Notes

Select this component when a 36 V reference or clamp is required in space-constrained designs utilizing the SMB footprint. Consider the 3.0 W power dissipation capability and the specific dynamic impedance profile for precision requirements. Evaluate thermal resistance parameters for heat management in steady-state operations.

Single Zener Diodes Part Context

This part belongs to the 3SMBJ5918B through 3SMBJ5956B series, covering a voltage range from 5.1 V to 200 V. All devices in this series share the same SMB (DO-214AA) surface mount package and 3.0 W power rating, differing primarily in their specific Zener voltage breakdown points and associated electrical test parameters.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 36 V Zener diodes in the DO-214AA (SMB) package with equivalent 3 W power ratings. Verify pinout compatibility and ensure thermal resistance values meet or exceed the original design requirements.
