BAT54S-HE3-18 Application Field and Working Principle

The BAT54S-HE3-18 is a type of dual Schottky rectifier which is suitable for a wide range of applications. The BAT54S-HE3-18 features a low forward voltage drop of 0.04V and a high maximum forward surge current of 3.2A.

The BAT54S-HE3-18 rectifier can be used in a range of applications, including power supplies, inverters, battery charging / discharging, polarity protection and switching applications. The quick switching speed of the device makes it an ideal choice for designs requiring high surge current, as well as low power loss.

Working Principle

The BAT54S-HE3-18 is a device consisting of two series-connected Schottky rectifiers. This type of rectifier works on the principle of a Schottky diode, which is a diode with a very thin metal layer (the Schottky barrier) between the two electrodes. The Schottky barrier height is much lower than that of a p-n junction, which helps to speed up the switching process. The Schottky diode also has a much lower forward voltage drop than a standard p-n junction diode, thus providing superior power efficiency.

The combination of two series-connected Schottky rectifiers in the BAT54S-HE3-18 device enables a higher current handling capability, as well as a lower forward voltage drop. This makes the device ideal for use in applications where both high surge current and low power loss are desired.

In operation, the BAT54S-HE3-18 acts as a two-way rectifier for AC voltage. When the positive voltage is applied, the positive Schottky rectifier conducts and the negative Schottky rectifier blocks. Conversely, when the negative voltage is applied, the negative Schottky rectifier conducts and the positive Schottky rectifier blocks. This allows for easy and efficient AC to DC conversion.

Advantages

The BAT54S-HE3-18 is a versatile and cost effective dual Schottky rectifier, offering a number of advantages over other rectifier devices. Its quick switching speed, low forward voltage drop, and high maximum surge current make it an ideal choice for low power loss designs.

The device is small in size and has a high power dissipation rating. In addition, the metal-oxide semiconductor (MOS) technology used to construct the device makes it environmentally friendly and free of harmful substances. This makes the BAT54S-HE3-18 an excellent choice for environmentally conscious designs.

Conclusion

In conclusion, the BAT54S-HE3-18 is an ideal device for a wide range of applications requiring high surge current, as well as low power loss. Its dual Schottky rectifier design offers a number of advantages over other rectifier technologies, such as a low forward voltage drop, quick switching speed and small size. In addition, the device is constructed using environmentally friendly MOS technology, making it safe to use in a range of applications.
