shTVS – DiodesTVS (Transient Voltage Suppressor) diodes are semiconductor devices designed to protect electronic circuits from high voltage transients, which can be caused by electrostatic discharge, inductive load switching, or any other reason. They are typically used in automotive, industrial, medical, and telecommunications fields. The TV02W190-G is one such device.This TVS diode is a unidirectional device with an emphasis of surge specifications for the 18V / 400W rating. It is also designed to provide low clamping voltage protection with minimal capacitance. The TV02W190-G has a continuously operating rating of 5 amps, an on-state voltage of 2.1V, a peak forward current of 8 amps, and a peak pulse rating of 400 watts.The TV02W190-G’s design and function is based on its dynamic compression characteristics, which makes it attractive for applications that require high reliability and meet industry standard surge requirements. Its silicon diode structure has two parts; an anode and a cathode. When an over voltage event occurs, the anode will attract the electrons, while the cathode will supply them. This action causes the current to flow from the anode to the cathode, through the TVS diode, reducing the effect of the transient voltage spike.The TV02W190-G is capable of clamping voltage to very low levels. The low clamping voltage of this device increases the safety margin of the ICs in the system by preventing the overvoltage from damaging them. It also helps in suppressing its own voltage, which is valuable in surge and noise reduction. The low capacitance feature of this device makes it easier to use in high speed applications, such as USB, as it does not slow down the data transfer rate or cause any glitches.The working principle of the TV02W190-G follows the general characteristics of a TVS diode, which consists of a junction diode and a control device, which together protect from severe over voltage transients. When an over voltage event occurs, the clamping voltage of the diode increases, increasing the resistance of the diode and reducing the current flow. The control device is triggered by the over voltage event and cuts off the current once a maximum voltage is reached.The TV02W190-G is suitable for a number of applications including automotive, industrial, medical, and telecommunications. The device’s surge and noise protection make it a great choice for these environments, offering superior performance and reliability. It is also a good option for high speed applications, as its low capacitance helps to maintain data transfer rates.
