Overview
The CDBQC0140R-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration in an SOD-923F-2 package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 40 V and an average forward current (If) of 100 mA. The device exhibits a low forward voltage drop (Vf) of 250 mV at rated current and a maximum reverse leakage current (Ir) of 10 uA. It supports a forward surge current (Ifsm) of 3 A and operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Low forward voltage drop for improved efficiency
- Majority carrier conduction for fast switching
- Extremely thin package suitable for small surface mounting
Applications
- DC/DC converters
- Power supply circuits
- Reverse polarity protection
Procurement Notes
Verify the specific suffix against official Comchip Technology documentation to confirm exact electrical tolerances and packaging details. Ensure the selected variant matches the required thermal and voltage ratings for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when space constraints require an extremely thin SMD package like SOD-923F-2. It is appropriate for low-current applications requiring 40 V blocking capability and minimal forward voltage loss. Confirm that the 100 mA average current rating meets the circuit's continuous load requirements.
Part Context
This part belongs to Comchip Technology's CDBQC series of automotive-grade Schottky diodes. The series emphasizes low profile and high reliability for compact electronic designs. The 'L' or 'R' suffix typically denotes specific tape and reel packaging configurations rather than functional differences.
Replacement Considerations
Consult official substitution guides for verified equivalents. Generic replacements must match the 40 V reverse voltage, 100 mA current rating, and SOD-923F-2 footprint to ensure compatibility.
