Procurement Notes

Verify the specific suffix and revision level against the official Comchip Technology datasheet before ordering. Confirm that the requested quantity aligns with current manufacturing availability, as lifecycle status may affect supply continuity. Ensure packaging specifications match the intended automated assembly requirements.

Selection Notes

Select this component when a low-profile surface mount Schottky rectifier is required for high-frequency switching applications. The 120 V rating provides adequate headroom for standard 12 V or 24 V bus systems. Consider the thermal resistance characteristics and the 1 A continuous current limit during circuit design to ensure reliable operation under peak load conditions.

Part Context

This part belongs to the CDBN series of low-profile Schottky barrier rectifiers from Comchip Technology. These devices utilize silicon epitaxial planar chip technology with a metal-silicon junction. The series is designed to offer superior power dissipation and lower reverse leakage compared to standard packages, making them suitable for space-constrained modern electronic designs.
