BAT43W-G3-18

Diodes are important electrical components in the electronics industry due to their ability to selectively pass current in one direction. Rectifiers are used to convert alternating current, or AC, to direct current, or DC. Single rectifiers are most commonly used as a full-wave rectifier, for low-power applications such as AC-DC power supplies. The BAT43W-G3-18 is a single rectifier element made by ON Semiconductor, a leading electronics distributor.

The BAT43W-G3-18 is a low-cost rectifier option and suitable for general-purpose rectification applications. It has a maximum forward voltage drop of 0.75 volts, with an compliant surge capability that can easily handle 5.0A continuous current. The device is considered an “ultra-fast” rectifier, and has a maximum reverse recovery time of 2 nano-seconds.

The BAT43W-G3-18 is available in TO-236AB, SC-59 and SMA packages. It can operate between -65°C and 150°C, and has a maximum reverse leakage current at 25°C of 100 nA. It is also RoHS-compliant, and provides improved ESD protection.

The working principle of the BAT43W-G3-18 is based on the function of a diode. Diodes act as a one-way conductor and block current from passing from the cathode to the anode. The BAT43W-G3-18 is designed to act as a rectifier, allowing only the positive portion of the AC signal to pass through the device. This results in a DC output with a voltage equal to the peak voltage of the AC input -- or twice that of the RMS voltage.

The BAT43W-G3-18 can be used in a variety of applications, such as in AC-DC rectification, motor driver circuits, and switch mode power supplies (SMPS). It is widely used in consumer devices, including TV sets, household appliances, and other electronic products. It is also commonly found in automotive electronics, air conditioner systems, and in communication equipment.

The BAT43W-G3-18 is an extremely versatile single-diode rectifier, and an ideal choice for a wide range of general-purpose rectification applications. It has a low forward voltage drop, robust surge capability and a fast switching time, making it a reliable and cost-effective solution for many projects.
