• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the manufacturer designation on the component marking, as the BZX85 series is produced by multiple vendors including ON Semiconductor and Vishay. Confirm that the specific part number matches the required 11 V Zener voltage and 5% tolerance specifications before integration into the design.

Single Zener Diodes Selection Notes

Select this component when a robust 11 V reference is needed in a standard axial package. Ensure the circuit design accounts for the 1.3 W power rating and derating requirements above 25°C. Verify compatibility with the DO-41 footprint and lead spacing during PCB layout.

Single Zener Diodes Part Context

This component belongs to the BZX85 series of power Zener diodes. The series offers various voltage options in the DO-41 package, designed for general-purpose regulation tasks. The 'C' suffix typically denotes a 5% voltage tolerance band.

Single Zener Diodes Replacement Considerations

Equivalent parts include BZX85C11 from other manufacturers such as ON Semiconductor or Vishay. Verify pinout compatibility and ensure the replacement meets the same 11 V nominal voltage and 1.3 W power dissipation ratings.
