Overview
The CDBA140LL-HF is a single-phase Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 40 V and an average rectified forward current of 1 A. The device exhibits a maximum forward voltage drop of 350 mV at 1 A and a maximum reverse leakage current of 1 mA. It supports a forward surge current of 50 A and operates within a junction temperature range of -65°C to +175°C. The component utilizes a DO-214AC (SMA) surface-mount package.
Feature Summary
- Ultra-high-speed switching capability with low power loss for high efficiency
- Guardring structure provides enhanced overvoltage protection
- Low profile surface mount design optimizes printed circuit board space
Applications
- Low voltage DC-DC converters
- Power supply circuits requiring high efficiency
- Free-wheeling diodes in inductive load applications
Procurement Notes
Verify the specific suffix designation, as variations such as -G or -HF indicate compliance attributes like halogen-free status which may affect material specifications. Confirm the package type matches the required footprint, typically DO-214AC for this series. Ensure thermal management aligns with the specified operating temperature range during integration.
Selection Notes
Select this component when a fast-recovery rectifier with low forward voltage drop is required for 40 V applications. The SMA package suits automated surface-mount assembly processes. Consider the 1 A current rating against peak load requirements and derating factors for capacitive loads to ensure reliable operation under all expected conditions.
Part Context
This part belongs to Comchip's SMD Schottky Barrier Rectifier series designed for low-profile applications. The family includes variants with different voltage ratings and current capacities, sharing common features like silicon epitaxial planar chips and metal-silicon junctions. The CDBA140LL-HF specifically targets compact designs needing efficient rectification at moderate voltages.
Replacement Considerations
Cross-reference with other 1 A, 40 V Schottky diodes in the SMA package from manufacturers such as Vishay or Diodes Inc. Verify pinout compatibility and thermal characteristics before substitution. Ensure the alternative device meets the same reverse voltage and forward current specifications for direct replacement.
