CD0603-Z3

Overview

The CD0603-Z is a surface mount Zener diode from the CD0603/1005-Z series, manufactured by Bourns Inc. It is available in compact 0603 (1608) and 1005 (2512) molded plastic packages with gold-plated terminals. The device provides nominal Zener voltages ranging from 2.0 V to 39 V. Key electrical parameters include a power dissipation of 0.5 W at 25°C, an operating temperature range of -55°C to +125°C, and a peak forward surge current of 0.2 A. The component conforms to JEDEC standards and RoHS directives.

Feature Summary

• Compact chip package design for PCB real estate savings
• Flat configuration minimizes roll away during handling
• Gold plated terminals ensure solderability per MIL-STD-750
• Conforms to JEDEC standards for standard pick and place equipment

Applications

• DC-DC converters
• Portable electronics
• Industrial controllers
• Desktop PCs and notebooks

Procurement Notes

Verify the specific voltage suffix (e.g., -Z3V3) as it defines the nominal Zener voltage. Confirm package size availability (0603 or 1005). Check datasheet revision dates as specifications are subject to change without notice. Ensure compatibility with RoHS Directive 2002/95/EC and Recast 2011/65/EU requirements for your manufacturing process.

Selection Notes

Select based on required nominal Zener voltage within the 2.0 V to 39 V range. Choose between 0603 and 1005 packages depending on board space constraints. Verify that the operating temperature range of -55°C to +125°C meets application thermal conditions. Consider dynamic impedance and reverse current characteristics for precision voltage reference needs.

Part Context

This component belongs to the CD0603/1005-Z Surface Mount Zener Diode Series. It is designed to address the industry challenge for increasingly smaller electronic components in portable communications and computing markets. The series offers general-purpose voltage regulation in ultra-compact formats compared to competitive parts.

Replacement Considerations

The datasheet states this series is currently available but not recommended for new designs. Evaluate alternative Bourns Zener diode series for new projects. Cross-reference pinout and package dimensions when substituting with other manufacturers' SOD323 or SOD523 compatible devices.
