The BAT47 is a very popular single diode and rectifier in the world of electronics. It has been used in a variety of applications including power supplies, regulated DC voltage sources, converter circuits, and more. This article will discuss the BAT47 application field, working principle, and other important characteristics of the device.

The BAT47 belongs to the Schottky barrier diodes family and has excellent characteristics like fast switching, low forward voltage drop, low reverse leakage current, and high frequency operation. The device has a maximum reverse voltage of 47 volts and a forward current of 100mA. Moreover, its temperature coefficient and reverse current leakage are relatively low.

The BAT47 can be used in various applications including DC/DC converters, AC/DC converters, power rectification, and switch mode power supplies. Due to its low forward voltage drop, the device can reduce conduction losses and consequently improve circuit efficiency. In addition, it can be used as a signal clamping device in order to limit the amplitude of input/output signal levels. Moreover, it is also suitable as an anti-parallel diode.

In terms of working principle, the main function of the BAT47 is to conduct current in one direction only and to block the current in the reverse direction. This operation principle can be understood by considering the electrical field inside the device. When a forward bias is applied, the electrical field breakdown the potential barrier between the two metal contacts thus allowing current flow. When the bias is reversed, the electrical field is destroyed and no current can flow.

The last important characteristic of the BAT47 is its temperature coefficient. The device has a temperature coefficient of 15ppm/°C which is relatively low compared to other single rectifier diodes. This low coefficient ensures that the device will work reliably across a wide temperature range, thus making it ideal for applications that operate in extreme environments.

In conclusion, the BAT47 is a very popular single diode rectifier with excellent characteristics and wide application field. Its low forward voltage drop and temperature coefficient make it an ideal choice for power conversion applications like DC/DC converters and switch mode power supplies. The device operates on the principle of electrical field breakdown allowing current conduction in one direction only.
