Diodes - Rectifiers - Single

The BAT42WS-G3-08 is a type of rectifying diode commonly used in single forward-voltage configuration. It is manufactured by NXP Semiconductors, a company specializing in a wide range of semiconductor components for industrial, aerospace, and consumer applications. The device is used in many types of applications, such as power supply circuits and rectification circuits.

Overview

The BAT42WS-G3-08 is a small plastic surface-mount rectifying diode, which is ideally suited for use in portable, consumer, building control, and automotive applications. It features a high reverse-voltage rating of 600 W, a low forward voltage drop of 0.56V and a maximum operating temperature of up to 175°C. Furthermore, the device has an efficient power dissipation of 0.5W and a low junction capacitance of 35pF. Additionally, it is available in an industry-standard SOD-323 package.

Functionality

The device is designed to provide rectification, or the conversion of alternating current (AC) to direct current (DC). It can be used to prevent over-voltage injury of other components, as well as for general power conversion applications. Because it is a diode, electricity will only flow in one direction; in the case of the BAT42WS-G3-08, the electricity will flow through the diode in the forward direction. The device also provides protection against noise, since the voltage drop in the forward direction limits the current flow.

Applications

The BAT42WS-G3-08 is a popular choice for many applications because of its robust nature and reliable performance. It is often used as a protection diode in power supplies and lighting circuits. Its low forward voltage drop makes it suitable for use in high-efficiency switching mode power supplies. Additionally, it can be used in voltage swap circuits, automotive systems, and signal transmission applications.

Working Principle

The BAT42WS-G3-08 works on the principle of PN junction diode, which can allow current to flow in one direction only. The current is limited by a diode\'s threshold voltage, which is determined by the applied voltage. The device works on the principle of negative temperature coefficient, which means that the threshold voltage tends to decrease with increasing temperature. This means that the current capacity of the diode changes with temperature, allowing it to produce a negative temperature coefficient.

Advantages

The BAT42WS-G3-08 is a reliable and efficient rectifying diode with numerous advantages. It has low forward voltage with a high reverse-voltage rating, allowing it to handle more than 600 W of reverse voltage. Additionally, its small size, wide industry-acceptance, and robust nature make it an ideal choice for a variety of applications. Finally, its low forward voltage drop and negative temperature coefficient make it particularly suitable for use in efficient, high-power applications.
