Overview
The CDBA120LL-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It belongs to the Low VF series, offering a maximum average forward current of 1.0 Amp and a maximum repetitive peak reverse voltage of 20 Volts. The device utilizes a JEDEC DO-214AC (SMA) molded plastic case with built-in strain relief. Key electrical characteristics include a low instantaneous forward voltage drop and high surge current capability, designed for efficient power conversion in compact electronic assemblies.
Feature Summary
- Super low forward voltage drop for improved efficiency
- Ideal for automated surface mount pick-and-place processes
- Built-in mechanical strain relief within the package
- Plastic encapsulation meets UL flammability classification 94V-0
Applications
- Surface mount applications requiring compact rectification
- Power supply circuits utilizing Schottky diodes
- Consumer electronics protection against voltage transients
Procurement Notes
Verify the specific suffix 'LL' against the official datasheet to confirm it aligns with the documented CDBA120L-G specifications. Ensure the component matches the DO-214AC package dimensions and polarity markings. Confirm RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency. The 1.0 Amp rating suits moderate current applications. Verify that the 20 Volt reverse voltage rating exceeds the circuit's peak operating voltage. Consider the SMA package size for board space constraints and ensure thermal management supports the specified junction temperature limits.
Part Context
This part is part of Comchip Technology's Low VF SMD Schottky Barrier Rectifiers family. It shares the same physical package and general electrical ratings as the CDBA120L-G, differing potentially in internal processing or specific performance tolerances defined by the manufacturer. It serves as a surface-mount alternative to through-hole rectifiers in modern PCB designs.
Replacement Considerations
The CDBA120L-G is listed as a related part number within the same product family. Verify if the 'LL' suffix denotes a specific variant or if they are functionally interchangeable based on the manufacturer's cross-reference data.
