TV04A100JB-G Circuit Protection

TV04A100JB-G is a kind of transient voltage suppressor diode (TVS), an electronic device that can protect against overvoltage, including power inductive kick due to inductive load switching, lightning, and power grid voltage spikes. This type of diode is used extensively in the automotive and industrial sectors, and in many consumer electronics applications. It is designed to protect against both positive and negative voltages and is suitable for use in the DC, AC, and signal line protection circuit.

Overview

The TV04A100JB-G has a stand-off voltage of 15V, a peak pulse power (PPP) of 500 watts (W), and a clamping voltage of 25V. It offers fast response time and is rated to protect voltage up to 22.5V. It has an insulation coating and excellent flexibility which makes it suitable for use in a variety of environments. Its electrical rating is 12A in 8/20 μs current waveform and 120W Ipp. It also offers satisfactory electrical stability. It is available in a variety of packages, including the 0402, 0603, 0805, 1206, and 1210.

Working Principle

The operation of the TV04A100JB-G is based on the principle of reverse breakdown voltage which is the voltage at which the transistor\'s breakdown occurs due to an increase in the current flowing through it. When a voltage difference exceeding the breakdown voltage is applied, the current flow will be limited by the clamping voltage of the diode. This clamps on the voltage, allowing the voltage to stay within the predetermined limits. This prevents voltage spikes from occurring due to either lightning, power grid switching, or other sources.

The TV04A100JB-G is a bilateral device, meaning it can be used to protect against both positive and negative voltages. When the TV04A100JB-G is connected to the input and output of an electronic device, it acts as a buffer between them, providing protection from electrical transients. This protection is achieved by the internal resistance of the device, which absorbs and distributes the current generated by the voltage spike.

Application Field

The TV04A100JB-G is suitable for applications that require protection from transient overvoltages and power inductive kicks due to inductive load switching, such as automotive electronics, industrial systems, and consumer electronics applications. It can be used in reverse current protection circuits and various power application protection circuits. It is widely used in the automotive and industrial sector, such as in connection with engine control units, air bags, ignition coils, power train control systems, and antenna systems. It is also suitable for use in consumer electronics products such as mobile phones, portable computers, home electronics, and other consumer products.

Conclusion

The TV04A100JB-G is a type of transient voltage suppressor diode (TVS) and is designed to protect against both positive and negative voltages. It offers fast response time, good electrical stability and insulation coating which makes it suitable for use in a variety of environments.
