Overview
The CDBFN140-G is a single Schottky barrier rectifier from Comchip Technology, housed in an SOD-323 surface-mount package. It features a repetitive reverse voltage of 40 V and an average forward current of 1 A. The device exhibits a maximum forward voltage drop of 550 mV and a reverse leakage current of 500 uA. It supports a forward surge current of 30 A and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Ultra-low forward voltage drop for high efficiency
- Guarding against overvoltage protection
- Ultra-high-speed switching capability
- Lead-free construction meeting environmental standards
Applications
- Low voltage, high frequency inverters
- Free wheeling diode applications
- Polarity protection circuits
Procurement Notes
Verify the specific suffix 'G' indicates lead-free compliance and RoHS adherence as per manufacturer documentation. Confirm the SOD-323 package dimensions match design constraints. Ensure the 40V rating aligns with circuit peak inverse voltage requirements. Check operating temperature limits against thermal management plans.
Selection Notes
Select this component for applications requiring low profile surface mount solutions with fast switching speeds. The 40V rating suits low-voltage DC-DC converters and power supplies. Consider the 1A current capacity for moderate load applications. Evaluate thermal performance at elevated ambient temperatures near the 125°C limit.
Part Context
This part belongs to the Comchip Technology Schottky Diodes series, designed for general-purpose rectification. It utilizes silicon epitaxial planar chip technology. The product line emphasizes low power loss and high efficiency. It serves as a compact alternative to larger through-hole rectifiers in modern electronics.
Replacement Considerations
Cross-reference with other SOD-323 Schottky diodes rated at 40V and 1A. Verify matching forward voltage and reverse leakage specifications. Ensure equivalent surge current handling capabilities. Confirm package compatibility for PCB footprint substitution.
