Overview
The CD1408-FF1400 is a surface-mount fast recovery rectifier diode manufactured by Bourns Inc. It features a single configuration within the SOD-87 package. The device supports a maximum repetitive peak reverse voltage of 400 V and a continuous forward current of 1 A. Key electrical characteristics include a forward voltage of 1.05 V, a maximum surge current of 30 A, and a reverse leakage current of 5 uA. The component exhibits a fast recovery time of 35 ns and operates reliably across a temperature range from -65 C to +175 C.
Feature Summary
- Fast recovery performance with a 35 ns switching time for efficient power conversion
- High thermal stability allowing operation up to +175 C junction temperature
- Leadless SMD design in a compact footprint to minimize PCB real estate usage
Applications
- General purpose rectification in high-frequency power supplies
- Free-wheeling diodes in DC-DC converter circuits
- Protection against voltage spikes in industrial control systems
Procurement Notes
Verify the specific suffix FF against official Bourns documentation to confirm tape and reel packaging requirements. Ensure the ordering quantity aligns with standard manufacturing reel sizes. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when a 400 V rating and 1 A current capacity are required in a small surface-mount form factor. The fast recovery characteristic makes it suitable for applications demanding low switching losses. Compare thermal resistance values against alternative packages if space constraints allow for larger footprints.
Part Context
This part belongs to the Bourns CD1408 series of chip diodes designed for lead-free manufacturing processes. The series utilizes a leadless package structure that facilitates automated assembly using standard pick-and-place equipment. The flat configuration helps prevent rollaway during production handling.
Replacement Considerations
Consult official substitution guides for equivalent fast recovery rectifiers in the SOD-87 package. Verify pin compatibility and thermal performance before replacing.
