Overview
The CDBF0530-HF is a single Schottky barrier rectifier diode manufactured by Comchip Technology. It utilizes silicon technology and is housed in an SMD/SMT 1005 (2512 metric) package, also identified as Case 1005 or SOD-323F. The device features a maximum repetitive reverse voltage (Vrrm) of 100 V and a forward current (If) rating of 300 mA. Key electrical parameters include a forward voltage (Vf) of 750 mV, a forward surge current (Ifsm) of 3 A, and a reverse current (Ir) of 50 uA. The component operates within a minimum temperature range of -55°C.
Feature Summary
- Schottky barrier construction for majority carrier conduction
- Low forward voltage drop design
- Leadless surface-mount package suitable for small mounting areas
Applications
- Fast switching applications
- Power supply rectification
- Reverse polarity protection circuits
Procurement Notes
Verify the specific datasheet version to confirm exact electrical tolerances and marking codes. Confirm RoHS compliance status and halogen-free designation with the manufacturer prior to ordering. Check for end-of-life notices or obsolescence warnings, as availability may be limited. Ensure the 1005 package footprint matches the PCB layout requirements exactly.
Selection Notes
Select this component when a low-profile surface-mount Schottky diode is required for high-frequency switching. The 1005 package offers space efficiency compared to larger through-hole alternatives. Consider the 750 mV forward voltage drop for thermal management calculations. Verify that the 100 V reverse voltage rating provides sufficient margin for the target circuit's peak inverse voltage conditions.
Part Context
This part belongs to Comchip Technology's Schottky Diodes & Rectifiers product line. It is designed for general-purpose rectification where speed and low loss are prioritized. The CDBF series typically includes variants with different voltage and current ratings, sharing similar package styles and manufacturing technologies.
Replacement Considerations
Cross-reference with other 100V, 300mA Schottky diodes in the 1005/SOD-323F package. Verify pinout compatibility and thermal characteristics before substitution.
