CDBA140-HF Description

Short technical summary and product information.

The CDBA140-HF is a Schottky barrier rectifier diode from Comchip Technology, designed for low power loss and high efficiency in surface-mount applications. It has a maximum reverse voltage (VRRM) of 40V and a forward current rating of 1A. The forward voltage drop is typically 0.5V at 1A, contributing to reduced power dissipation. The device can handle a forward surge current of 30A (8.3ms half sine wave) and exhibits a low reverse leakage current of 0.5mA at 25°C. The junction capacitance is 88pF at 1MHz and 4V reverse bias. The operating junction temperature range is -50°C to 150°C. The diode is housed in a molded plastic DO-214AC (SMA) package with solderable terminals per MIL-STD-750, method 2026. It is RoHS3 compliant and halogen free. The part is suitable for high-speed switching, polarity protection, and DC-DC converter applications.
