Rectifier diodes typically convert alternating currents (AC) into direct currents (DC) for use in electrical systems. Rectifier arrays are integrated circuits which contain multiple rectifier diodes in one package. The FST8380SM is a rectifier array integrated circuit manufactured by Fairchild Semiconductor. It is used in a range of applications from motor control to power management, and can help to reduce the complexity of a system by operating as a single chip style solution.

The FST8380SM is an eight-pin surface mount package with a thermal resistance of 8 °C/W. It consists of two integrated rectifier diodes and an open drain output pin. The FST8380SM features a low forward voltage drop, high surge current capability, and fast switching speeds. The two integrated rectifier diodes within the FST8380SM have a maximum reverse voltage of 400 volts, and a maximum forward voltage drop of 0.95 volts at 1 ampere. The open drain output pin provides a high-level logic signal for light load operations, and can be used in conjunction with the rectifier diodes for more complex operations.

The FST8380SM operates at up to 420 volts peak, and has a power input capable of handling up to 3 watts. Due to its relatively low power output, it is suitable for various low voltage applications such as motor control, power management, and portable electronics. Moreover, the FST8380SM offers improved ESD protection over traditional Schottky diodes which provides additional protection against electrostatic discharges. Consequently, the FST8380SM is ideal for use in applications where ESD protection is important.

The FST8380SM has a working principle similar to a diode rectifier array, with the two internal rectifier diodes working independently. The input signal is applied to the diode array and the output signal forms at the common ground point. The output signal is a rectified version of the input signal which is used to drive electronic circuits such as relays and solenoids. As the FST8380SM is an integrated circuit, all the components are integrated onto a single silicon chip which reduces the space, cost and complexity of the system compared to the use of multiple discrete diodes.

The FST8380SM is a feature-rich integrated rectifier array, suitable for a variety of low power applications. Its low forward voltage drop, high surge current capability, as well as its ESD protection capabilities make it an appealing choice for a variety of design scenarios. Additionally, its small form factor and integrated nature helps reduce complexity and cost, making the FST8380SM an attractive solution for small sized, low power projects.
