Bridge rectifiers are types of diodes which are used to rectify alternating current (AC) to direct current (DC). The DB107S-G bridge rectifier is a full wave bridge rectifier with automatic temperature and overload protection. It is designed for use in a wide range of applications which include LED, LED display, switching power supply, charger, motor driver, automotive lighting and more.

The DB107S-G bridge rectifier is a 4-terminal package rectifier with a high peak inverse voltage of 1000V, a reverse surge current of 1A, and a non-repetitive peak pulse current of 16.7A. In order to protect the rectifier from damage caused by excessive temperature or load, the rectifier is designed with an automatic temperature and overload protection system. This system acts as a self-regulating fuse, meaning it is able to automatically adjust the amount of current that passes through the rectifier to prevent overloads or overheating.

The DB107S-G bridge rectifier is a four-layer bridge rectifier. Its working principle is simple and is based on the principle of a forward bias p-n junction diode. Each of the four diodes within the bridge rectifier acts as a switch, which allows the circuit to switch between forward and reverse biasing.

When an alternating current (AC) voltage is applied to the diode bridge, the device is forward biasing each diode in turn. This allows the current to flow from the positive side of the AC supply though the diode and through the resistor. The resistor is placed in the circuit in order to limit the current. The voltage across the resistor and the current in the current are in phase and are used to convert the AC input to a DC output.

When the current polarity reverses, the forward biasing of the diode switches to a reverse bias, which prevents current flow. The diode then acts as a switch, blocking current flow in the opposite direction. This process is repeated each half-cycle of the AC input, resulting in DC pulses which flow in one direction across the load.

The DB107S-G bridge rectifier is a versatile device suitable for a wide range of applications. Its temperature and overload protection system ensures safe operation, and its automatic sensing of voltage allows it to maintain a steady DC output. Furthermore, its four-layer construction and small size make it ideal for use in high power, compact applications. This makes it an ideal choice for AC to DC conversion in numerous applications.
