TVS – Diodes

Transient Voltage Suppression (TVS) diodes are a form of semiconductor component specifically designed to protect semiconductors from voltage transients induced by lightning and electrostatic discharge (ESD). TVS diodes are designed to protect voltage-sensitive circuits from destructive high-voltage surges. They are used in many different applications across the world.

CD214B-T22ALF Application Field and Working Principle

The CD214B-T22ALF is a stand-alone transient voltage suppressor designed to protect against high-volume surges due to lightning and other power events. It is recommended for use in sensitive electrical components such as communication connections, AC/DC power lines, and sensitive analog circuits as an inexpensive component that can be quickly installed in any circuit. This device operates by using a junction breakdown voltage breakdown effect to suppress the transient voltage through a controlled flow of current. The CD214B-T22ALF is rated for a breakdown voltage of 12V, peak pulse current of 480A, and a clamping voltage of 15V.

The CD214B-T22ALF TVS device features a fast response time of 1µs to limit the overvoltage transient to a safe level. It also helps protect components from high-frequency noise such as switching surges. The device has a maximum breakdown voltage of 12V, and is capable of protecting a wide range of circuit loads. The device is designed to block reverse currents while allowing forward currents to pass uninterrupted, thus ensuring that sensitive equipment and components remain safe even in the event of a voltage surge.

The device also features an internal zener diode which provides additional protection. This diode is designed to reduce the turn-off time of the device in the event of an overvoltage condition. The device also has an internal series inductor and a bidirectional ESD protection which ensures that it is capable of suppressing lightning surges up to 25A while limiting the ESD current to a safe level.
