Overview
The CDBA340LL-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in a DO-214AC (SMA) package. The device is rated for a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 3 A. Key electrical characteristics include a low forward voltage drop of 0.4 V at the rated current and a maximum non-repetitive peak forward surge current of 125 A. It operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Low forward voltage drop for enhanced efficiency
- High thermal stability with extended operating temperature range
- Surge current capability for robust protection
Applications
- Power supply circuits
- Free-wheeling diodes
- Polarity protection
Procurement Notes
Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the component meets required RoHS compliance standards for your target market. Cross-reference the part number with authorized distributors to confirm authenticity and traceability before procurement.
Selection Notes
Select this component when a low-loss rectification solution is required in space-constrained designs. The SMA package offers a balance between current handling and board area. Consider the 40 V rating relative to the circuit's peak inverse voltage to ensure adequate safety margins under all operating conditions.
Part Context
This part belongs to Comchip Technology's SMD Schottky Barrier Rectifier series, specifically designed for low-voltage, high-efficiency applications. The 'LL' suffix typically denotes Low Voltage Drop characteristics, distinguishing it from standard variants within the same physical package family.
Replacement Considerations
Direct substitutes include CDBA340L-HF and CDBA340LR-HF from the same manufacturer. Verify pinout compatibility and thermal resistance values when considering cross-brand alternatives.
