A TVS (transient voltage suppressor) is a type of electrical component designed to protect vulnerable components from high voltage transients. The VE1812K801R014 is a type of TVS specifically designed to protect Hybrid Electric Vehicles (HEV) and Electric Vehicle (EV) power electronics circuits against destructive electrical transients such as those caused by load dump and ESD (Electro-Static Discharge).

This TVS device features a low stand-off voltage and a low leakage, allowing it to minimize power dissipation and energy losses. It also possesses a high surge current capability, making it suitable for a wide range of high power applications. The device is also designed with a low capacitance to keep noise levels low in high frequency applications.

The working principle of the VE1812K801R014 hinges on the principle of voltage clamping. This is a method of limiting the instantaneous peak voltage developed on a circuit node by clamping the voltage to a maximum value. This is achieved by connecting a TVS to an appropriate location in the circuit to function as a voltage-limiting device. Under normal conditions, the circuit does not draw any current through the TVS and remains in an off condition. However, once an excessive voltage is detected, the TVS conducts the electrical current away from the vulnerable components while keeping the voltage level within the specified limits.

When it comes to its application field, the VE1812K801R014 is primarily used to protect the power electronic circuits of HEVs and EVs. The device is also capable of protecting high power switching devices, low voltage motors, safety systems, battery protection circuits, and other high power applications that could be damaged by high voltage events. Furthermore, it has a high surge current capability and is suitable for a variety of high power applications.

The VE1812K801R014 is an excellent choice for protecting consumer’s vehicles from excessive voltages. Its low stand-off voltage and low leakage ensure that the device is minimally power dissipating and energy wasting, while its low capacitance ensures that noise levels remain low in high frequency applications. And lastly, its high surge current capability allows it to be used for a variety of different high power applications.
