The working principle of a CDBM140LR-HF is fairly simple. It is a three-terminal device with two power diodes connected in parallel for full-wave rectification. When a source is connected to its input terminals, the bridge rectifier will allow current to flow only when the supply reaches its minimum threshold voltage. Once this threshold has been reached, alternating current will be converted into direct current through the rectifier, with current flowing either forward or reversed depending on the voltage polarity.

The CDBM140LR-HF offers full-wave rectification with low reverse current losses, low surge voltage and low power loss. It has high EMI immunity and excellent thermal stability. The device has built-in protection circuits such as overvoltage and short-circuit protection to ensure safe and reliable operation. It also has excellent surge current capability and a wide operating temperature range, making it an ideal choice for a variety of applications.
