In many areas of electricity and electronics, diodes, rectifiers, and arrays serve a wide range of applications. The FST8335SM is one such device, offering the exceptional features of low drop voltage, high current, and fast switching speeds. This article will go over the applications of the FST8335SM device and its working principle.

Application Field:

The FST8335SM is a switch-mode power supply rectifier array with reverse blocking capabilities. It can operate from input voltage levels from 4 V up to 40 V. The internal fault protection characteristic helps prevent the passage of current from input to output during an overload or short circuit condition. The device can also be “hot-swapped”, meaning that it can be quickly removed from the system and replaced with a new unit without having to power down the circuit. As such, the FST8335SM is used in several applications, including but not limited to consumer electronics, automotive, and telecom applications.

In consumer electronics, the FST8335SM is used in high current applications such as laptop power supplies and PDAs. Due to its low drop voltage, it can help reduce the power consumption of the system. In automotive applications, the FST8335SM can help protect against overvoltage, short circuit and reverse-voltage conditions. In telecom applications, it’s most commonly used to power WIC cards, routers, and other telecom-related equipment.

Working Principle:

The FST8335SM is a multiple-diode rectifier array that works by using two center-tapped diodes to shunt excess current away from the output stage. When the device is connected to an external power supply, a small amount of current flows through the diodes to create two voltage dividers on the output. One of the voltage dividers is used to regulate the current and the other is used to regulate the voltage.

When the AC input voltage is applied to the FST8335SM, the internal diodes start to conduct. This creates a closed loop with the external power supply and the FST8335SM. The current that flows through this loop is then regulated by the voltage dividers. The voltage at the output is also regulated by the voltage dividers. When the voltage at the output reaches the correct level, the internal diodes stop conducting and the device is ready for operation.

In summary, the FST8335SM is a rectifier array with exceptional features and can be used in various applications. It works by using two center-tapped diodes to regulate both the current and the voltage at the output, which helps protect against overvoltage, short circuit and reverse-voltage conditions. The FST8335SM is a great choice when dealing with high current, low drop voltage and fast switching speeds.
