TVS diodes are used to protect sensitive circuitry from high voltage and high-energy electrical transients. The TV15C180J-G is a transient voltage suppressor (TVS) device designed to protect sensitive and high voltage electronic devices from overvoltage and power surge events. This TVS diode is designed for high-energy transient protection, and it can also be used for reverse-bias protection of CMOS devices such as microprocessors, memory chips and other integrated circuits. It is capable of withstandingsurges up to 15kV (impulse).

The primary function of the TV15C180J-G is to suppress electrical transient peaks, which are very fast rise time-voltage overshoots, by providing a low resistance conduction path for the current to flow. It\'s also capable of clamping very high peak surge currents, providing protective action for sensitive components.

The TV15C180J-G is constructed from two series-connected chips. These chips are designed to handle high energy transients up to 15kV (impulse). When the voltage exceeds the device\'s rated maximum voltage (Vmax), the internal diodes will be driven into avalanche breakdown, allowing current to pass through the device. The device will then enter what is referred to as the "secondary breakdown" region, where the current is limited and the device will dissipate much of the energy in the form of heat.

The TV15C180J-G is designed to operate in temperatures ranging from -55°C to +125°C. The device is rated for a maximum peak pulse current of 180A and a standwith resistence of 45mΩ. The device also has an operating voltage range of 8-22V and a leakage current of 5uA at 25°C. The device is designed for application in automotive, professional audio-video, consumer, telecommunications, computer and industrial equipment.

The TV15C180J-G has a wide range of applications, such as providing protection against overvoltage due to power surges, electrostatic discharge (ESD), or other transient events. In automotive and consumer applications, it can provide reverse-polarity and reverse-bias protection for sensitive devices such as microprocessors, memory chips and other integrated circuits. In professional audio-video applications, it can provide surge protection for audio and video systems and protect other sensitive components from overvoltage or power surge events. In telecommunications applications, it is capable of withstanding high peak surge current up to 180A, providing protection against power surges that may occur on the line.

The TV15C180J-G can also be used in conjunction with metal-oxide varistors (MOVs) for surge protection in computer and industrial equipment. In these applications, the TV15C180J-G will provide primary protection against high peak surge current, while the MOV will provide secondary protection against overvoltage conditions.

Overall, the TV15C180J-G offers an effective transient voltage suppressor protection solution for a variety of applications. It is designed for maximum surge suppression and energy dissipation, providing robust protection for sensitive components and systems. It is easy to install, reliable and cost effective, making it an ideal choice for protecting electronic devices against transient voltage and power surge events.
