FST8345SM is a 3-terminal Positive Voltage Surge Suppressor Array specially designed for high-reliability automotive, industrial and commercial applications. It can protect against voltage transients caused by inductive switching, ESD and other fast rise transients. The device consists of a low capacitance N-channel MOSFET and a Schottky diode in a SMD (Surface Mount Device) package that can dissipate up to one watt of power over a wide range of temperatures.

The working principle of the FST8345SM is based on its two core components, a N-channel MOSFET and a Schottky diode. The MOSFET acts as a high-speed switch in response to a fast-rising transient or ESD strike. The MOSFET quickly clamps the voltage to a safe level, preventing it from exceeding the maximum rated value. During this clamping process, the Schottky diode also plays a role. It helps dissipate the energy generated by the voltage transients and prevents the voltage from reaching dangerous levels.

The FST8345SM has a wide range of applications and can be used in a variety of systems. It can be used in automotive systems to protect automotive components and modules from excessive voltage transients and ESD strikes. It can also be used in industrial applications such as PLCs, Stepper Motors and Power Supplies, etc. It can also be used in consumer electronics, including cell phones, cameras and computers.

The FST8345SM is an excellent choice for high-reliability, high-temperature applications. It is manufactured using advanced fabrication techniques that enable it to maintain its performance over a wide temperature range. The device can also handle high surge currents, making it suitable for use in harsh environments.

The FST8345SM is a reliable and effective solution for protecting sensitive electronic systems against voltage transients. It is easy to install and can be used in various systems. It is also cost-effective, making it a great choice for designers who need reliable and efficient voltage transients protection.
