Transient Voltage Suppressors (TVSs) are one of the most common protection elements used in numerous applications. They help protect against spike and surge-currents that may be induced in an electronic system from a power or signal-line. The ATV15C200J-HF is designed to protect sensitive electronic components connected to the power supplies, digital lines and communication buses. This device is a silicon-avalanche Diode and belongs to the family of TV Signal Suppressors.

The ATV15C200J-HF is an unidirectional Transient Voltage Suppressor designed for suppressing surge impulses such as electrostatic discharges (ESD) and transients. The device has excellent ESD protection capability due to its high surge current withstand capability and low leakage clamping. It has a compact form-factor making the device suitable for applications that require space-saving protection.

The ATV15C200J-HF TVS is designed with an integrated circuit technology to provide low operating voltage, high reliability and fast reacting protection. The device is constructed of an integrated silicon avalanche diode and resistive components. The diode is used to clamp the voltage and the resistive components are used to reduce the voltage. The integrated circuit technology allows for the device to be constructed in a small size and in a cost-effective way.

The ATV15C200J-HF has a clamping voltage of 200 V and can handle surge currents up to 15 A. It has an ultra-low leakage current typically 0.1 µA. The device can operate with a junction temperature range from - 55°C to + 150°C. It is designed with an epoxy case style which makes it compatible with many application requirements.

The most common application field of the ATV15C200J-HF is in automotive applications. It is used to protect micro-control units and ECU from the transients caused by electrostatic discharges and voltage spikes. This device also widely used in various communication, consumer electronics, and other applications where it is important to protect the sensitive circuits from transients.

The working principle of ATV15C200J-HF TVS is based on the avalanche breakdown of its integrated diode. When a current surge with a voltage greater than the rated clamping voltage is applied to the ATV15C200J-HF TVS device, its diode begins to break down the voltage and clamps it to the rated value. The resistive components present in the circuit helps in limiting the surge current and reducing the voltage.

In conclusion, the ATV15C200J-HF is designed with a combination of integrated diode and resistive components which helps it to provide excellent protection against surge and transient currents. The device is suitable for a wide range of applications including automotive, communication, consumer electronics, and other applications requiring protection from transients.
