The BAT42W-7 is used as a bridge rectifier in power supplies, lighting applications, and general rectification purposes. The device is also suitable for use in applications where a high forward current is required.

Construction

The BAT42W-7 is a small plastic package with a two-terminal separable copper-clad stainless steel enclosure. The two terminals are identified as the anode (positive) and cathode (negative). The package is hermetically sealed to protect from any physical and environmental damage.

Working Principle

The BAT42W-7 operates as a full-wave bridge rectifier, converting AC power to DC power. In an AC power circuit, the BAT42W-7 is connected across the AC load. As the AC voltage changes polarity, the device conducts current across the load. In this operating mode, the two terminals of the BAT42W-7 rectify current alternately. When the positive terminal of the device is connected to the positive terminal of the AC source, the current is conducted from the positive to the negative terminal of the device; when the positive terminal of the device is connected to the negative terminal of the AC source, the current is conducted from the negative to the positive terminal of the device.

Functional Characteristics

The BAT42W-7 has a high reverse blocking voltage of 500V and a forward current rating of 30A. The device is capable of handling highreverse voltage and high forward current, making it suitable for use in AC/DC converter circuits, DC/DC converters, and in power circuits where high power dissipation may be encountered. The device also offers excellent heat transfer characteristics, making it suitable for use in applications with high power levels. Additionally, the device has a low profile, making it easy to install in tight locations.
