CD1005-Z33

Single Zener Diodes Overview

The Bourns CD1005-Z33 is a surface mount Zener diode from the CD0603/1005-Z series, housed in a compact 1005 (2512 metric) package. It provides a nominal Zener voltage of 33 V with a tolerance range of 31.35 V to 34.65 V at a test current of 5 mA. The device features a maximum dynamic impedance of 80 Ohms and a reverse leakage current of 0.1 mA. Rated for operation between -55 °C and +125 °C, it offers 0.2 W power dissipation and supports peak forward surge currents of 0.2 A.

Single Zener Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm exact electrical tolerances and marking codes. Confirm RoHS compliance status as required by project specifications. Ensure the component matches the intended 1005 package dimensions for proper pad layout compatibility. Validate that the operating temperature range meets environmental requirements.

Single Zener Diodes Selection Notes

Select this component when space-constrained designs require a 33 V reference or protection level. The 1005 package size is suitable for applications needing smaller footprints than standard SOD packages. Verify that the 80 Ohm dynamic impedance aligns with circuit stability requirements. Consider the -55 °C to +125 °C range for broad environmental applicability.

Single Zener Diodes Part Context

This part belongs to the Bourns CD0603/1005-Z Surface Mount Zener Diode Series. The series covers Zener voltages from 2.0 V to 39 V in both 0603 and 1005 formats. These devices are engineered for voltage reference applications in portable communications, computing, and video equipment markets where miniaturization is critical.

Single Zener Diodes Replacement Considerations

Check datasheets for other manufacturers offering 1005 package Zener diodes with similar 33 V nominal ratings. Verify pinout polarity and physical dimensions match the existing pad layout. Ensure thermal characteristics and impedance values are comparable for direct substitution.
