Diodes - Rectifiers - Single

The CD214A-B140LR is a voltage controlled rectifier device that is categorized under single diodes. This component acts as both a rectifier, device that allows electric current to flow in one direction only, and a voltage-controlled device, device whose output voltage is regulated by the input voltage. The CD214A-B140LR is capable of blocking and rectifying AC mains safely and comes along with a reverse power supply protection.

Application Field

The CD214A-B140LR is used in several different applications and is limited to only a few, making it ideal for multiple applications. One of the primary uses of the CD214A-B140LR is protection against reverse polarity damage. This component is also used in communication equipment and display devices. This component is ideal for use in power supplies, signal amplifiers, switchmode power supplies, switching circuits, and voltage regulators.

Working Principle

The CD214A-B140LR works as a rectifier, device that allows electric current to flow in one direction only, by blocking the negative current coming in from either side of the input AC source. This is done by limit the voltage drop across the component to a few mV, depending on the AC voltage level. Once blocked, the desired DC voltage is set by a voltage regulator.

As a voltage-controlled device, the CD214A-B140LR can regulate the output voltage to remain within a set range. This is done by controlling the current between the anode and cathode connection of the device. The output voltage is then regulated as required and the current flow is maintained within a set range.

Conclusion

The CD214A-B140LR is an ideal component for single diode rectification. This component provides protection against reverse power damage and can regulate the output voltage to a set range. This component is ideal for use in several applications including communication equipment and display devices, power supplies, signal amplifiers, switchmode power supplies, switching circuits, and voltage regulators.
