Working Principle of GBJ2001TB

GBJ2001TB is designed to regulate large amounts of direct current (DC) and provides short-circuit protection. It is a bridge rectifier that converts alternating current (AC) into DC power. Its two main components are two thyristors, also known as silicon controlled rectifiers (SCRs).

The two SCRs form a bridge of four diodes, which is responsible for blocking current. These diodes act as switches and allow current to flow in one direction only. The SCRs act as switches as well, functioning as a single pole, double throw (SPDT) switch. When the current reaches the predetermined levels, the SCRs switch the current in the opposite direction, which prevents overloading the power supply and more importantly, protect the circuit from being damaged.

Moreover, GBJ2001TB also features robust overcurrent protection and variable threshold options, allowing the circuit to handle large unpredictable current load and protect itself from overload.

Conclusion

GBJ2001TB is an ultra-fast bridge rectifier developed by Infineon. It is designed for applications involving direct current power supply and voltage regulation and is available in different packages to suit various applications. The two SCRs forming the bridge of four diodes allow current to flow in one direction only and provide excellent short-circuit protection up to 15A in typical applications.
