CD0603-B00340

Overview

The Bourns CD0603-B00340 is a Schottky Barrier Chip Diode in a leadless 0603 package. It features a repetitive peak reverse voltage of 45 V and a maximum forward voltage of 0.37 V at 1 mA. The device supports an average forward current of 30 mA with a surge peak current of 500 mA. Key electrical parameters include a maximum reverse current of 1 µA at 40 V and a maximum capacitance of 1.5 pF at 1 V. Power dissipation is rated at 150 mW, operating within a junction temperature range of -40 to +125 °C.

Feature Summary

• Leadless molded plastic construction for PCB real estate savings
• Low stored charge and low forward voltage characteristics
• Compatible with standard pick and place equipment due to flat configuration

Applications

• Cellular phones
• PDAs
• Desktop PCs and notebooks
• Digital cameras
• MP3 players

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact electrical tolerances and termination plating specifications. Ensure the component meets RoHS compliance requirements for your manufacturing process. Confirm that the 0603 package dimensions align with your board layout constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring minimal footprint and fast switching speeds. The low forward voltage reduces conduction losses, while the high reverse voltage rating provides robust protection. Consider the 30 mA average current limit when designing power paths. Verify thermal management capabilities given the 150 mW power dissipation rating in confined spaces.

Part Context

This part belongs to the CD0603/1005 Schottky Barrier Chip Diode Series by Bourns. The series addresses miniaturization demands in portable communications and computing markets. Other variants in the family offer different current ratings and voltage thresholds, all sharing the same compact leadless design philosophy for efficient surface mount integration.

Replacement Considerations

Check datasheets for other CDxxxx-B00340 variants from different manufacturers offering identical 0603 footprints and matching 40V/30mA specifications. Verify pinout polarity and physical dimensions to ensure compatibility with existing pick-and-place programming and soldering profiles.
