TVS - Diodes are widely used in many industries and often revered for their performance in surge protection. One type of TVS diode, the 3KP90C, is particularly useful in protecting against electrical surges. This article outlines the application field and working principle of the 3KP90C TVS diode.

The 3KP90C is a surface-mount type TVS diode. This bi-directional device is designed to provide protection against surges with up to a 90 volt peak pulse voltage (3KW surge power). This diode has a flat, symmetrical response curve, meaning it is ideal for applications with repetitive high-voltage surge events. This device features excellent clamping capability and can dissipate large amounts of surge current safely.

The 3KP90C is commonly used in applications such as medical electronics, communication devices, automobile parts, industrial equipment, and consumer electronics. Additionally, this device is also capable of being used as an overvoltage protection device in non-surge events, due to its flat response curve.

The working principle of the 3KP90C TVS diode is actually quite simple. The diode has two unmatched diodes connected in series to form a full-wave junction. Each diode is capable of conducting current in both the forward and reverse directions and will clamp any voltage on either side that exceeds the breakdown voltage of the TVS diode. Typically, this breakdown voltage is between 60 and 90 volts depending on the device being used. When a surge occurs, the current will flow through the diode out into the circuit. Once the voltage drops below the breakdown voltage, the diode will stop conducting any current. Therefore, the TVS diode will absorb the energy from the surge, protecting the circuit from further damage.

In summary, the 3KP90C is a type of TVS diode designed for surge protection. This device features flat, symmetrical clamping capability, enabling it to handle repetitive surges. Additionally, this device can also be used to provide overvoltage protection. The working principle of this device involves two unmatched diodes connected in series to form a full wave junction that clamps any voltage that exceeds the breakdown voltage of the diode. With its wide range of applications and capabilities, the 3KP90C is an excellent choice for surge protection.
