Overview
The CD1408-FU1400 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 an average forward current of 1 A. Key electrical parameters include a forward voltage of 1.05 V, a maximum surge current of 30 A, and a reverse current of 5 uA. The component exhibits a recovery time of 35 ns and operates within a temperature range of -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 chip design in SOD-87 package to minimize PCB footprint and prevent rollaway during assembly
Applications
- General purpose rectification in compact electronic systems
- Power supply circuits requiring high-speed switching
- Consumer electronics and telecommunications equipment
Procurement Notes
Verify the specific suffix FU against the official Bourns datasheet to confirm the 400V rating and 35ns recovery time specifications. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Confirm RoHS compliance status through the latest product change notifications or datasheet documentation before finalizing procurement.
Selection Notes
Select this component when a small form factor is required alongside high-temperature resilience. The SOD-87 package offers space savings compared to traditional leaded packages. Consider the 35 ns recovery time for applications demanding faster switching speeds than standard rectifiers provide. Verify that the 400V reverse voltage rating meets the circuit's peak inverse voltage requirements.
Part Context
This part belongs to the Bourns CD1408 series of chip diodes, which are designed for miniaturization in modern electronics. The series utilizes leadless terminations to facilitate automated pick-and-place manufacturing. These components conform to JEDEC standards and are compatible with lead-free manufacturing processes, addressing space constraints in dense PCB layouts.
Replacement Considerations
Cross-reference the CD1408-F1600 for higher voltage ratings (600V) if the application requires increased reverse voltage tolerance. Verify pinout compatibility and thermal characteristics when substituting with other SOD-87 fast recovery diodes from different manufacturers.
