The TSH346IDT is a member of STMicroelectronics’ power fast-transistors family. It has achieved a well-deserved reputation for providing reliable and efficient video performance for a wide range of applications. These devices are typically used in amplifiers, DC-DC converters, power conditioning circuits, and output stages in video equipment. The TSH346IDT is a self-biased device featuring a 95A high-side FET, a high-speed short-circuit protection circuit, a complimentary low-side FET, and an embedded current-protection circuit.

The device offers an ultra-low on-resistance at 6.5 mOhms, which offers a significant power saving in various applications. The very fast switching behavior (<10ns) makes it suitable for use in high-frequency switching and AC-DC conversion. The low output capacitance between the gate and source of the device (6pF) ensures fast and safe operation of the device under switching stress condition. The TSH346IDT has a superior power capability of up to 500W and robust thermal characteristics with a thermal resistance of just 12°C/W.

The TSH346IDT video clip level amplifier is an ideal electric circuit for driving all kinds of video frames that are widely used in modern video and PC based systems. It offers an output current range from 1A to 5A and a peak power rating up to 50W. The device supports excellent linearity, along with a high input impedance, low distortion, and low total harmonic distortion (THD). The low input-offset voltage (max. 250mV) and wide bandwidth (270MHz) provides good signal integrity and excellent performance.

The TSH346IDT provides additional protection features to ensure reliable operation, such as the thermal shutdown that helps protect against over temperature conditions, and the current limit and soft start feature which helps protect against short circuit and inrush current. Additionally, the short-circuit protection feature eliminates noise and eliminates the need for additional external components.

The TSH346IDT also offers an integrated active compensation circuit which results in better stability and power efficiency in high-speed operation. This active compensation helps to reduce noise in the output and reduce current consumption, resulting in improved overall performance. The device also offers a wide input voltage range from 5V to 45V, making it ideal for low-voltage operations and high-current applications.

The TSH346IDT provides the flexibility to easily customize the working parameters such as the threshold voltage, the current limit, and the turn-on/turn-off delay. This makes it suitable for a wide range of applications including industrial, automotive, appliance, AV/IT, test and measurement, and medical equipment.

In summary, the TSH346IDT is an excellent choice for a wide range of linear and switch-mode power conditioning circuits and output stages in video equipment. It offers excellent performance, high power output, a low on-resistance, high input impedance, and extensive protection features, making it an ideal solution for any video system application.
