Desktop PCs and notebooks

Procurement Notes

Verify component authenticity by cross-referencing the part number against official Bourns documentation. Confirm that the specific suffix matches the required voltage tolerance and package dimensions. Ensure compliance with RoHS directives if environmental regulations apply to your assembly process. Check for any design-in restrictions as this series may not be recommended for new designs.

Selection Notes

Select this component when space constraints require a 1005 footprint while maintaining precise voltage regulation. Evaluate the thermal derating curve to ensure power dissipation limits are respected under operating conditions. Consider the dynamic impedance and reverse leakage specifications to verify suitability for the target circuit's noise and stability requirements.

Part Context

This device belongs to the Bourns CD0603/1005-Z Surface Mount Zener Diode Series. The series offers Zener voltages ranging from 2.0 V to 39 V in both 0603 and 1005 package sizes. These components are engineered for portable communications, computing, and video equipment markets where miniaturization is critical.
