Overview
The CD1607-B140LF is a Schottky Barrier Rectifier Chip Diode manufactured by Bourns Inc. It features an average forward current of 1 A and a repetitive peak reverse voltage of 40 V. The device utilizes a Mini-SMA (1607) surface mount package with lead-free terminations compliant with RoHS standards. Key electrical parameters include a maximum forward voltage of 0.5 V at 1 A, a typical junction capacitance of 110 pF, and a maximum reverse current of 0.5 mA at rated voltage. The component supports a junction temperature range from -55°C to +125°C.
Feature Summary
- Low profile surface mount configuration in a compact Mini-SMA package for PCB real estate savings
- Very low forward voltage drop characteristic for efficient rectification
- Lead-free construction ensuring compliance with environmental directives
Applications
- Cellular phones
- PDAs
- Desktop PCs and notebooks
- Digital cameras
- MP3 players
Procurement Notes
Verify the specific suffix 'LF' indicates 100% tin terminations as defined in the ordering guide. Confirm that the 'B140' designation corresponds to the 40 V reverse voltage rating. Ensure the procurement documentation references the correct JEDEC standard package dimensions for the 1607 case style to guarantee compatibility with automated pick-and-place equipment.
Selection Notes
Select this component when a 1 A average forward current and 40 V blocking capability are required in a small form factor. Consider the 'L' suffix variants if a lower forward voltage drop is necessary for the application. Evaluate the thermal resistance characteristics against the expected ambient temperatures to ensure reliable operation within the specified junction temperature limits.
Part Context
This part belongs to the Bourns CD1607 series of Schottky Barrier Rectifiers designed for portable electronics. The series offers various voltage ratings including 20 V and 40 V options. The components are engineered to replace larger through-hole diodes, providing significant size reduction while maintaining performance suitable for high-frequency switching applications in consumer devices.
Replacement Considerations
Cross-reference with other manufacturers offering Mini-SMA packaged Schottky diodes with matching 1 A and 40 V specifications. Verify pinout polarity and physical dimensions to ensure mechanical fit. Check datasheets for equivalent forward voltage and reverse leakage current values to confirm functional interchangeability.
