TV15C140J-HF represents a device class in the TVS diode family. This class of TVS diode is used to protect circuits and devices from over-voltage transients. It provides a low capacitance, high-speed switching protection against transient voltages caused by surges, voltage spikes, ESD (electrostatic discharge) or lightning.

The TV15C140J-HF contains a zener diode and an avalanche diode in a single package. The zener diode clamps the voltage to a safe level while the avalanche diode provides a rapid path to ground for the surge current. The device has a working voltage of 15V with a maximum working current of 140A, a peak surge current of 40.8A and a maximum peak pulse power of 630W. The TV15C140J-HF also provides excellent clamping performance with a typical breakdown voltage of 18V and a capacitance of 28pF under 5V.

TV15C140J-HF is widely used in various application fields, such as lightning protection of electronic control panels, data lines, communication lines, and automotive electronics. The device is also suitable for data bus protection in computers and industrial automation systems.

The working principle of TV15C140J-HF is simple. When a transient voltage exceeds its clamping voltage, the avalanche diode triggers and conducts the current to ground. This quickly limits the voltage, thereby protecting the connected circuits or devices from voltage transients. The zener diode clamps the voltage to a safe level, ensuring that the transient voltage does not overshoot or damage the connected components.

The TV15C140J-HF is designed to provide reliable, cost-effective protection for audio video equipment, data lines, and other sensitive components. It provides excellent surge handling capability and a low power dissipation. The device can be used in various application fields, and offers a reliable solution for both high-speed and low-capacitance transient protection.
