TV04A191J-G Datasheet/PDFTV04A191J-G is a type of TVS – Diodes, which is an abbreviation used to represent transil and transient voltage suppressors. A TVS diode is a type of semiconductor which is designed to protect sensitive electronic components from voltage spikes which can cause electrical overstress (EOS). They are used in different applications such as automotive, industrial, and consumer electronics, and they provide surge protection and over-voltage protection.
The TV04A191J-G is specifically designed to provide strong surge protection and fast response time. It can be used in a variety of applications, including automotive, digital equipment, as well as consumer electronics. This type of TVS diode provides a breakdown voltage of 191 Volts with a clamping voltage of 250V. It has a current rating of 8A peak pulse, as well as an ESD protection of up to IEC-61000-4-2 (ESD) ±15kV (air) and ±8kV (contact).
The working principle of the TV04A191J-G involves clamping the overvoltage to a safe level and diverting the excess charge. This is achieved by the action of the semiconductor diode, which absorbs the excess voltage and redistributes it by discharging it to the ground or a voltage reference. The surge protection is provided by the device\'s voltage rating, which is the maximum voltage it can safely handle before it starts to break down.
When a TV04A191J-G is installed, it is connected between the power supply and the circuit it is protecting, so that it can monitor the voltage levels and act as a gatekeeper that prevents overvoltage from entering the protected circuit. When an overvoltage situation arises, the diode acts as a switch to divert the excess charge to the ground or a voltage reference.
The TV04A191J-G is ideal for automotive, digital equipment, and consumer Electronics applications that require strong surge protection and fast response time. It is an affordable and reliable device that provides protection against voltage spikes and can be used to protect sensitive and valuable electronic components and systems from electrical overstress.
