CD1408-FF1800

Overview

The Bourns CD1408-FF1800 is a surface-mount Schottky barrier rectifier diode designed for high-efficiency power conversion applications. It utilizes the compact CD1408 package format, which provides minimal packaging overhead to support circuit miniaturization. The device features a forward current rating of 1 A and offers repetitive peak reverse voltage options ranging from 20 V to 40 V. Constructed with lead-free Cu/Ni/Au plated terminations, it ensures compatibility with lead-free manufacturing processes and adheres to JEDEC standards. The flat configuration minimizes rollaway during automated assembly.

Feature Summary

• Schottky barrier technology for low forward voltage drop and fast switching
• Compact leadless CD1408 package for PCB real estate savings
• Lead-free construction with Cu/Ni/Au terminations
• Flat profile compatible with standard pick-and-place equipment

Applications

• High-frequency DC-DC converters
• Power supply rectification circuits
• Reverse polarity protection in compact electronics

Procurement Notes

Verify the specific suffix code on the ordering part number to confirm the exact repetitive peak reverse voltage rating (20 V, 30 V, or 40 V), as this parameter varies within the series. Confirm RoHS compliance status and ensure the component meets the required JEDEC moisture sensitivity level for the intended assembly process. Cross-reference the terminal plating specification to guarantee compatibility with soldering requirements.

Selection Notes

Select this component when space constraints require a leadless SMD form factor without sacrificing current handling capability. The 1 A forward current rating suits moderate power applications where efficiency is critical. Ensure the chosen voltage variant aligns with the maximum reverse voltage present in the circuit. Consider the thermal management requirements associated with the small footprint during high-current operation.

Part Context

This model belongs to the Bourns Chip Diode product line, engineered to replace larger through-hole or standard SMD packages like SOD80. The series emphasizes miniaturization while maintaining robust electrical performance. It is distinct from general-purpose silicon rectifiers by utilizing Schottky technology for superior speed and lower power loss in high-frequency environments.

Replacement Considerations

Direct substitutes must match the 1 A forward current, CD1408 package dimensions, and identical voltage rating. Verify that alternative Schottky diodes maintain comparable reverse leakage characteristics and thermal resistance values to ensure equivalent circuit performance.
