• Overvoltage protection in low-power electronic systems
• Clamping applications in signal conditioning paths

Single Zener Diodes Procurement Notes

Verify the specific suffix E3-08 to confirm RoHS compliance and tape-and-reel packaging configuration. Ensure the ordering part number matches the required SOT-23-3 footprint and thermal characteristics. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 47 V Zener voltage is required in a small surface-mount form factor. The 225 mW power rating suits low-current regulation tasks. Consider the SOT-23-3 package constraints for PCB layout and thermal management requirements compared to larger axial or DO-214AA alternatives.

Single Zener Diodes Part Context

This part belongs to the MMBZ5261B series of single Zener diodes from Vishay. It shares the core 47 V specification with other variants but differs in packaging and power handling. The E3 designation indicates lead-free construction, aligning with modern environmental standards for semiconductor components.

Single Zener Diodes Replacement Considerations

Direct substitutes include MMBZ5261B-E3-18, which shares identical electrical parameters but may differ in packaging quantity or reel specifications. Verify pinout compatibility and thermal resistance values when substituting.
