Overview
The CDBA1150-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in the DO-214AC (SMA) package. Key electrical parameters include a repetitive reverse voltage of 150 V and a forward current rating of 1 A. The device exhibits a maximum forward voltage drop of 0.92 V at 1 A and supports a forward surge current of 50 A. It operates within a temperature range of -55°C to +150°C.
Feature Summary
- Schottky barrier construction for ultra-high-speed switching and low power loss
- Low forward voltage drop to enhance overall circuit efficiency
- High surge current capability for robust overvoltage protection
- Lead-free composition compliant with environmental standards
Applications
- DC-DC converter circuits
- Power supply freewheeling applications
- Reverse polarity protection in electronic systems
Procurement Notes
Verify the specific datasheet version from Comchip Technology to confirm exact thermal resistance values and mechanical dimensions. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, as these affect handling procedures. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a low-profile SMA package is required for high-frequency rectification. The 150 V rating suits intermediate voltage levels, while the 1 A current capacity fits moderate power applications. Consider the 150°C junction temperature limit for high-thermal environments compared to standard silicon rectifiers.
Part Context
This component belongs to the Comchip Technology SMD Schottky Barrier Rectifier series. It utilizes silicon epitaxial planar chip technology with a metal-silicon junction. The series is designed to offer excellent power dissipation and better reverse leakage current characteristics compared to standard rectifiers.
Replacement Considerations
The SS115H is listed as a similar alternative in distributor catalogs. Verify that the substitute maintains compatible voltage, current, and package specifications before implementation.
