TVS (Transient Voltage Suppressor) devices, MOVs (metal oxide varistors) and V140LT20CPX340 are all components used in protecting sensitive circuits from surges and other voltage fluctuations. These components are among the most widely used in the electronics industry.

TVS devices are diodes that act as a fast-acting, bidirectional circuit protectors that can carry up to a certain amount of energy before breaking down. MOVs are capacitive components that generally have high resistance to steady DC voltages as well as transient voltages, such as spikes, surges, sags, voltage drops, and other abrupt fluctuations in voltage.

V140LT20CPX340 is a TTL (Transistor-to-Transistor Logic) over-voltage protector device that is designed to protect sensitive electronic circuitry from extreme voltage events. The device is a bidirectional, 3-terminal uni-directional over-voltage protector with a clamping voltage of 400 volts. It is designed to protect both +5v and -12v lines from high surge events while allowing low level signals to pass with minimal attenuation and no false triggering.

The working principle of the V140LT20CPX340 device is based on its unique v-shape design. When the voltage of the sensitive circuitry exceeds the designated threshold, the device will act like a crowbar and will conduct current through its two terminals, diverting the excess voltage away from the protected circuit. This diverting of the excess voltage is referred to as “clamping” and is what makes the device an effective protector. The device also features a soft-start function which allows the device to discharge the stored energy over time, minimizing the stress on the protected circuit.

V140LT20CPX340 devices have a wide variety of applications due to their exceptional performance. They have been used successfully in various audio and music equipment, automotive, communication, consumer electronics, industrial automation, medical, and military/aerospace applications. More specifically, these devices protect sensitive circuitry from ESD (electrostatic discharge) events, lightning-induced over-voltages, and voltage transients. They are likely to be found in audio systems, automotive ECUs, power supplies, PCs, industrial control systems, and many more.

V140LT20CPX340 devices are ideal for protecting sensitive circuitry from sudden extreme voltage events while still allowing low level signals to pass through. In addition, the unique v-shape design of the device and its soft-start function provides advanced protection against both ESD events and lightning-induced over-voltages with minimal or no false triggering. Its wide variety of applications and its performance make it an ideal choice for many different kinds of electronic circuits.
