CD1005-S0180R

Overview

The CD1005-S0180R is a high-speed switching chip diode from Bourns Inc., housed in a compact 0603 (1608 metric) surface-mount package. It features an average forward current rating of 100 mA and a repetitive peak reverse voltage of 90 V, with a maximum reverse voltage of 80 V. The 'R' suffix designates a low leakage reverse current option, limited to a maximum of 0.05 µA at 75 V reverse bias. Electrical performance includes a maximum forward voltage of 1.00 V at 100 mA, a maximum terminal capacitance of 4 pF at 100 MHz, and a maximum reverse recovery time of 4 ns. Power dissipation is rated at 150 mW for the 0603 case size.

Feature Summary

• High-speed switching capability optimized for digital signal applications
• Low leakage reverse current configuration for enhanced efficiency
• Leadless construction with Cu/Ni/Au plated terminations for lead-free manufacturing compatibility
• JEDEC standard compliance ensuring reliability in portable electronics

Applications

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

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's official datasheet specifications against the supplied documentation. Confirm that the part marking corresponds to the S2 code designated for the CDxxxx-S0180R series. Ensure that the ordering information matches the specific electrical parameters required for the application, particularly the low leakage current rating associated with the R suffix.

Selection Notes

Select this component when space constraints require a 0603 footprint while maintaining high-speed switching performance. The low leakage characteristic makes it suitable for sensitive analog or RF circuits where minimal reverse current is critical. Consider the 150 mW power dissipation limit and ensure adequate thermal management on the PCB. Verify that the 80 V reverse voltage rating meets the circuit's peak inverse voltage requirements.

Part Context

This device belongs to Bourns' Switching Chip Diode Series, which also includes variants like the CD1005-S01575 and the non-low-leakage CDxxxx-S0180. The series was designed to address the industry demand for smaller components in portable communications and computing equipment. While offering significant PCB real estate savings compared to competitive parts, the datasheet notes that this series is currently available but not recommended for new designs.
