​TVS-Diodes, also known as Transient Voltage Suppression Diodes, are a type of diode that are designed to protect elements in electrical circuits from voltage spikes, transients, and noise on power lines. The 3KP120C is a TVS-Diode in a passivated flat two-lead configuration manufactured by Littelfuse. This diode is designed to protect sensitive components in a circuit from voltage transients, overload voltage, transient overvoltage, and electrostatic discharge (ESD).

The 3KP120C has a wide range of applications, mainly in automotive electronics, industrial control, telecommunications, consumer electronics, and audio/video systems. This diode can be used in applications where high speed tolerance and low capacitance are critical. It is also ideal for use in applications where it is necessary to protect radio frequencies in systems like GSM, EDGE, HSDPA, and LTE.

The 3KP120C is a bidirectional diode, meaning it can handle voltage spikes in either direction. It has a low on-state voltage of 0.7 V and a high-speed response time of 10 ns. In addition, the device can hold up to 150 V, with a pulse power rating of 1200 Watts. This makes it an excellent choice for protection against ESD strikes and other transient surges.

The 3KP120C has a working principle that is fairly simple. The voltage of the circuit is constantly monitored, and if a surge occurs, then the diode conducts the surge to the ground, thus diverting current from other components in the circuit. This prevents those components from being damaged by a high Voltage transient.

The 3KP120C is an important device for any circuit where protection against voltage surges is needed. It is an ideal solution for the protection of sensitive components in the automotive, industrial control, telecommunications, consumer electronics, and audio/video electronics fields.
