Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the part number suffix indicates RoHS compliance. Check datasheet revisions for potential updates to specifications or packaging details before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 12V Zener reference in an SMA package. Ensure the application stays within the 3.0W steady-state power dissipation limit. Consider the thermal resistance values for heat management. Verify that the operating environment falls within the specified -55°C to +150°C junction temperature range for optimal performance.

Single Zener Diodes Part Context

This part belongs to the 3SMAJ5918B through 3SMAJ5956B series, covering a voltage range from 5.1V to 200V. All devices in this family share the same DO-214AC surface mount package and 3.0W power rating. The series provides various voltage options for general-purpose Zener diode applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 3W SMA Zener diodes with a 12V nominal voltage and ±5% tolerance. Ensure equivalent thermal resistance and package dimensions match the design constraints. Verify that alternative components meet the same moisture sensitivity and flammability ratings.
