CD123D-B140LR Description

Short technical summary and product information.

The Bourns CD123D-B140LR is a Schottky barrier diode designed for high-efficiency rectification and switching applications. It offers a maximum reverse voltage of 40V and an average forward current of 1A at 55°C ambient temperature. The diode features a low forward voltage of 0.37V typical at 1A, reducing power dissipation and improving system efficiency. With fast recovery time (≤500ns) and low junction capacitance of 115pF at 4V, it is suitable for high-frequency circuits.

 

This diode is housed in a compact surface mount 123D chip package with concave terminals, compatible with SOD-123 footprint. It operates over a temperature range of -55°C to 125°C and can withstand non-repetitive surge currents up to 20A. The component is RoHS3 compliant and halogen free per Bourns definition, making it suitable for environmentally conscious designs.

 

Typical applications include portable communications, computing, and video equipment where space and power efficiency are critical. The low forward voltage and fast switching characteristics make it ideal for DC-DC converters, polarity protection, and freewheeling diodes in power management circuits.
