Overview
The CDBA140-G is a single-phase Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 1.0 A. The device exhibits a maximum instantaneous forward voltage of 0.75 V at 1.0 A and a maximum instantaneous reverse current of 10 mA at its rated DC blocking voltage. It operates within a junction temperature range of -65°C to +150°C and utilizes a DO-214AC (SMA) surface-mount package.
Feature Summary
- Low forward voltage drop for improved efficiency
- Built-in strain relief for mechanical stability
- Ideal for automated pick-and-place surface mount applications
Applications
- Surface mount rectification circuits
- Polarity protection in low voltage systems
- Free wheeling diode applications in high frequency inverters
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package type. Ensure compliance with RoHS standards and UL flammability classification 94V-0 requirements for your application. Confirm that the SMA (DO-214AC) footprint matches your PCB layout design before procurement.
Selection Notes
Select this component when a 1.0 A current rating and 40 V reverse voltage capability are required in a compact surface-mount form factor. Consider the thermal resistance characteristics and operating temperature range relative to your system's heat dissipation capabilities. Verify compatibility with automated assembly processes due to the standard SMA package design.
Part Context
This component belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology, covering voltage ratings from 20 to 100 Volts. The series is designed for surface mount applications, offering easy pick-and-place functionality and plastic packages with Underwriters Lab flammability classification 94V-0. The CDBA140-G specifically provides a 40 V reverse voltage rating within this lineup.
Replacement Considerations
Compatible substitutes include other SMA-packaged Schottky rectifiers with matching 1.0 A forward current and 40 V reverse voltage ratings. Verify pinout polarity and physical dimensions to ensure board compatibility. Check datasheets for equivalent forward voltage drop and thermal resistance values.
