Overview
The CDBQR0230R-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features a single silicon junction housed in an extremely thin, leadless 0402 (SOD-923F) package. The device is designed for high-efficiency rectification with low forward voltage and minimal reverse leakage current. Key electrical ratings include a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 100 mA. It supports a peak forward surge current of 3 A and operates within a junction temperature range up to 150 °C.
Feature Summary
- Extremely thin and leadless package design optimized for small surface mounting
- Low forward voltage characteristic for improved power efficiency
- Minimal reverse leakage current due to majority carrier conduction
Applications
- Power supply circuits requiring compact form factors
- High-frequency rectification in portable electronic devices
- DC-DC converter input/output stages
Procurement Notes
Verify the specific suffix 'HF' indicates halogen-free compliance as per manufacturer standards. Confirm the package designation matches the SOD-923F footprint requirements for your PCB layout. Ensure thermal management aligns with the specified junction temperature limits during operation.
Selection Notes
Select this component when space constraints necessitate a 0402 footprint while maintaining Schottky performance. Compare against standard packages if higher current capacity is required. Validate that the 30 V reverse voltage rating exceeds the maximum circuit voltage spikes.
Part Context
This part belongs to Comchip's CDBQR series of low-profile SMD Schottky diodes. The series emphasizes miniaturization through leadless packaging technologies suitable for automated assembly processes. It complements other variants in the lineup offering different voltage and current ratings within the same physical envelope.
Replacement Considerations
Check for direct substitutes from Comchip such as the CDBQR0130R or CDBQR0140R which share similar package dimensions but differ in voltage ratings. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers.
