Overview
The CDBQC0240LR-HF is a Schottky barrier diode manufactured by Comchip Technology. It features a maximum repetitive reverse voltage (Vrrm) of 40 V and an average forward rectified current (Io) of 200 mA. The device utilizes silicon technology and is housed in a compact SOD-923F-2 surface-mount package, also identified as 0402C. Key electrical specifications include a maximum forward voltage (Vf) of 580 mV at 200 mA and a maximum reverse leakage current (Ir) of 1 µA. The component supports a peak forward surge current (Ifsm) of 3 A and operates within a junction temperature range from -55 °C to +150 °C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Compact SMD footprint suitable for space-constrained designs
- High thermal stability with extended operating temperature range
Applications
- DC-DC converter output rectification
- Low voltage power supply circuits
- Portable electronic devices requiring small form factors
Procurement Notes
Verify the specific suffix 'LR' against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure the ordering part number matches the exact voltage and current ratings required for the target application circuit design.
Selection Notes
Select this component when a low-profile surface-mount Schottky diode is required for 40V applications. The SOD-923F-2 package offers a smaller footprint compared to standard SOD-123 variants. Confirm that the 200 mA current rating meets the load requirements and that the 580 mV forward voltage is acceptable for the system efficiency targets.
Part Context
This part belongs to Comchip Technology's line of small-signal Schottky rectifiers. It is designed for general-purpose rectification in consumer electronics and industrial control systems where size and switching speed are critical factors. The series provides reliable performance in low-voltage, high-frequency environments.
Replacement Considerations
Consult official substitution guides for equivalent 40V 200mA Schottky diodes in SOD-923F packages. Verify pinout compatibility and thermal characteristics before replacing.
