Single Zener Diodes Procurement Notes

Verify the authenticity of the component by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeits. Confirm that the ordering suffix indicates tape and reel packaging containing 3,000 pieces per reel. Ensure compliance with specific project requirements regarding moisture sensitivity and halogen-free status before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 15V Zener reference is required in space-constrained surface mount designs. The SMB package offers higher power dissipation capabilities compared to smaller packages like SMA or SOD-123. Consider the thermal resistance characteristics and operating temperature range to ensure suitability for the intended environmental conditions.

Single Zener Diodes Part Context

This part belongs to the 3SMBJ5918B through 3SMBJ5956B series, covering a voltage range from 5.1V to 200V. These diodes are designed for general-purpose voltage regulation and protection tasks. The series utilizes standard SMB surface mount packaging to balance power handling with board space efficiency.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 3W Zener diodes in the SMB package with a 15V nominal voltage and ±5% tolerance. Verify that alternative components match the thermal resistance, maximum forward voltage, and reverse leakage current specifications to maintain circuit performance.
