Overview
The CDBA340-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface mount applications. It features a DO-214AC (SMA) package and utilizes silicon epitaxial planar chip technology with a metal-silicon junction. The device supports a maximum repetitive peak reverse voltage of 40 V and a DC blocking voltage of 40 V. It provides an average forward current rating of 3.0 A and can withstand a non-repetitive peak forward surge current of 70 A under JEDEC method conditions. The component operates within a temperature range of -50°C to +150°C.

Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package type. Ensure compliance with RoHS standards as indicated in the datasheet. Check for halogen-free status if required by project specifications. Confirm that the ordering suffix matches the intended voltage and current requirements before procurement.
Selection Notes
Select this component when a 40V reverse voltage rating and 3A forward current are required in a compact SMA package. Consider its low forward voltage drop characteristics for efficiency-critical designs. Evaluate thermal resistance parameters for heat dissipation needs in the target application environment.
Part Context
This component belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology. The series covers reverse voltages ranging from 40 to 100 Volts with a consistent 3.0 Amp forward current rating. These devices share common mechanical and electrical features tailored for surface mount technology.
Replacement Considerations
Compatible substitutes include other 40V 3A Schottky diodes in the DO-214AC package. Verify pinout compatibility and thermal performance metrics before substitution.
