Overview
The CDBQR0130R is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum DC reverse voltage (Vr) of 30 V and an average forward rectified current (Io) of 100 mA. The device utilizes a 0402 (SOD-923F) package, suitable for compact circuit designs. Forward voltage (Vf) is specified at 450 mV when tested at a forward current (If) of 10 mA. Reverse leakage current is limited to 500 nA at a reverse voltage (Vr) of 10 V. The component supports a maximum operating junction temperature of 125°C and is classified as a small-signal diode with arbitrary speed characteristics.
Feature Summary
- Schottky barrier technology ensures low forward voltage drop and high switching efficiency.
- Compact 0402 surface-mount footprint enables dense PCB layout optimization.
- High thermal stability supports operation up to a 125°C junction temperature.
Applications
- Polarity protection circuits
- Low voltage rectification in portable devices
- Free-wheeling diodes in small signal applications
Procurement Notes
Verify the specific suffix 'R' against official manufacturer documentation to confirm packaging details, such as tape and reel specifications. Ensure compatibility with RoHS3 standards if required by the target assembly process. Cross-reference the exact part number with authorized distributors to validate current availability and lead times. Confirm that the 0402/SOD-923F package dimensions align with the intended PCB footprints before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a compact Schottky diode with a 30 V reverse voltage rating and 100 mA current capacity. The low forward voltage characteristic makes it suitable for low-voltage power paths where efficiency is critical. Consider the 0402 package size for space-constrained designs. Evaluate the 500 nA reverse leakage specification to ensure it meets the requirements for low-power standby modes or sensitive analog sections within the system.
Part Context
This component belongs to the CDBQR series of surface-mount Schottky diodes from Comchip Technology. The series is designed for general-purpose rectification and switching applications in consumer electronics and industrial control systems. The 0402 form factor represents a miniaturized option compared to larger packages like SOD-323, catering to the trend toward smaller electronic devices. It shares the fundamental Schottky characteristics of fast recovery and low loss typical of the brand's discrete semiconductor lineup.
Replacement Considerations
The CDBQC0130L-HF is listed as a manufacturer-recommended alternative. Verify electrical parameter equivalence, specifically the 30 V reverse voltage and 100 mA current ratings, before substitution. Check for any differences in forward voltage or package tolerance that might impact circuit performance.
