Procurement Notes
Verify the specific ordering suffix against official Comchip Technology documentation to confirm compliance status and marking codes. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revision B specifications before finalizing orders.
Selection Notes
Select this component for designs requiring a 100 V reverse voltage rating and 3.0 A continuous forward current in a compact SMA package. Consider the thermal resistance characteristics and derating curves for capacitive loads when determining heat dissipation requirements. Evaluate the forward voltage drop and reverse leakage current specifications against system efficiency targets.
Part Context
This component belongs to the CDBA series of SMD Schottky Barrier Rectifiers manufactured by Comchip Technology. The series encompasses devices with reverse voltages ranging from 40 V to 100 V and a consistent 3.0 A forward current rating. All variants share the DO-214AC package form factor and utilize silicon epitaxial planar chip technology.
Replacement Considerations
Direct substitutes include other 100 V, 3 A Schottky rectifiers in the DO-214AC package such as the CDBA3100-G. Verify pinout compatibility and electrical parameter margins before substitution.
