TVS - Diodes are special components designed to protect a circuit from overvoltage conditions. It primarily works by inversely biasing a Zener diode with a low power rating to prevent voltage disturbance on the input port. These components are often referred to as Transient Volute Suppressors, as by design they are meant to protect sensitive components from stray voltage by clamping a voltage spike before it reaches them.

The 1.5SMC39AHR7G is a Transient Voltage Suppressor (TVS) diode designed to protect a circuit from ESD attacks, electrostatic discharges, and other surges up to a peak power of 39A. With a maximum working voltage of 1000V, the product is designed to protect high value components against large surges. As a Pb (lead) free device, it is ideal for consumer and office applications such as computers, modems, and laser printers.

The device is designed to have a low forward voltage drop, meaning it does not consume much energy, and is meant to protect electrical circuits from lightning strikes, power surges, electrical discharges, and other disturbance that may cause electrical breakdown. It works by allowing current to flow through its symmetry while the device is in a normal operating mode. When the voltage or current of its input exceeds its breakdown voltage, the structure of the TVS diode will become triggered and reverse the biasing direction of the diode, in turn creating a protection voltage within the circuit and protecting critical components.

The 1.5SMC39AHR7G is able to reduce noise to a range of 800mV (8V peak) and trap voltage up to 1000V. The product can also operate at a wide -40°C and +125°C temperature range and comes with a maximum capacitance of 10pF. The product provides both ESD and surge protection once activated, and has the capability to absorb power dissipation up to 200W.

Overall, the 1.5SMC39AHR7G is an ideal product for protecting electrical circuits from ESD and transient voltage surges due to its ability to reduce noise and absorb power. Its low forward voltage drop ensures that the device does not consume much energy and the wide-temperature range allows for the product to be employed in multi-application scenarios. The product is an effective solution for providing surge protection to consumer and office equipment, such as computers, modems, and laser printers.
