The CDBA140-G is a Schottky barrier rectifier diode manufactured by Comchip Technology. It is designed for surface mount applications and offers a maximum reverse voltage of 40V and an average rectified current of 1A. The diode features a low forward voltage drop of 0.5V typical (0.55V maximum) at 1A, which enhances efficiency in low-voltage circuits.
Key electrical characteristics include a maximum peak forward surge current of 30A (8.3ms single half sine-wave) and a maximum reverse current of 0.5mA at rated DC blocking voltage. The device has a fast reverse recovery time of 500ns maximum, suitable for high-frequency switching applications. Thermal resistance is 88°C/W junction-to-ambient and 28°C/W junction-to-lead, allowing for effective heat dissipation.
The CDBA140-G is housed in a DO-214AC (SMA) surface mount package with solderable terminals per MIL-STD-750. Polarity is indicated by a color band on the cathode end. The operating temperature range is -65°C to 125°C, and storage temperature range is -65°C to 150°C. The package is UL 94V-0 rated for flammability.
This diode is ideal for use in power supply rectification, freewheeling diodes, and polarity protection circuits. Its low forward voltage and fast switching make it suitable for DC-DC converters and battery-powered devices.
