Overview
The CDBQR0130R-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a maximum repetitive reverse voltage of 30 V and an average forward rectified current of 100 mA. The device utilizes a compact SOD-923F (0402) package, suitable for space-constrained PCB layouts. Key electrical characteristics include a forward voltage of 450 mV at 10 mA and a low reverse leakage current of 500 nA at 10 V. It operates within a junction temperature range up to 125°C and is supplied in tape and reel packaging.
Feature Summary
- Schottky barrier construction enables fast switching speeds with minimal reverse recovery time.
- Low forward voltage drop reduces power dissipation and improves overall circuit efficiency.
- Compact SOD-923F footprint supports high-density surface-mount assembly processes.
Applications
- DC-DC converter output rectification
- Power supply freewheeling diodes
- Reverse polarity protection circuits
Procurement Notes
Verify the specific suffix 'HF' confirms RoHS compliance and halogen-free status as per manufacturer specifications. Confirm the package designation matches SOD-923F dimensions for PCB footprint compatibility. Ensure the ordering quantity aligns with standard tape and reel quantities provided by authorized distributors to maintain component integrity during handling.
Selection Notes
Select this component when a small form factor is required alongside moderate current handling capabilities. The 30 V rating suits low-voltage logic and battery-powered systems. Consider the thermal performance limits if operating near the maximum junction temperature. Compare forward voltage specifications against alternative Schottky devices to ensure optimal efficiency for the specific load conditions.
Part Context
This part belongs to Comchip Technology's general-purpose Schottky diode lineup, characterized by silicon planar construction. The series targets consumer electronics and portable devices where size and speed are critical. It complements higher-current variants in the same family, offering a solution for signal-level or low-power rectification tasks requiring reliable performance.
Replacement Considerations
Cross-reference with other 30 V, 100 mA Schottky diodes in the SOD-923F package. Verify pinout compatibility and thermal resistance values before substitution. Ensure the alternative device meets the same reverse leakage and forward voltage requirements for equivalent circuit behavior.
