APT20DC120HJ

Diodes - Bridge Rectifiers

The APT20DC120HJ is a diode bridge rectifier with an operating temperature range from -40°C up to +125°C. It is a bridge-based device most commonly used in a wide variety of electrical and electronic circuits, including low-voltage AC-to-DC rectification, as well as power management and control applications.

Bridge rectifiers are composed of two or more diodes used in a ‘bridge’ configuration to provide full-wave rectification. They are relatively simple devices but are incredibly versatile, providing a vital link in circuit engineering that has been extended and adapted to new technologies while remaining largely unchanged in its working principle.

The APT20DC120HJ bridge rectifier is designed with a peak inverse class voltage of 1200 volts and a current rating of 20 amps. It is also designed to have an extremely low forward voltage drop and a very rugged construction with an insulation grade of UL94V-0. This helps make it a suitable device for a wide range of applications, including power supplies and switching regulators, as it can handle higher input voltages, long inrush currents, and can provide better efficiency than other bridge rectifiers.

The way it works is fairly straightforward. As shown in the diagram below, the four diodes are arranged in a bridge configuration, so that when an AC voltage is applied to the A and C terminals, the current flows through two diodes and forms a rectified output at the B and D terminals.

The APT20DC120HJ Bridge Rectifier has several significant advantages over other bridge rectifiers. First, it is able to withstand overloads and reverse voltages much better than conventional Bridge Rectifiers. Also, it is able to handle longer inrush currents than standard Bridge Rectifiers, so it is suitable for high power applications. Additionally, it also delivers high reliability as it is highly efficient and has a low thermal resistance. Finally, it is designed with an excellent thermal stability and boasts very low reverse leakage current.

In conclusion, the APT20DC120HJ Bridge Rectifier is an essential component for a variety of electrical and electronic circuits. It is an extremely versatile device that can handle higher input voltages, long inrush currents, and it has a very rugged construction and insulation grade. Furthermore, it delivers reliable performance and offers several significant advantages over other bridge rectifiers.
