Diodes - Bridge Rectifiers

The SCBK4F is a bridge rectifier diode in the Small Signal Rectifier series from STMicroelectronics. It is composed of four independent plastic-encapsulated diodes which are available in the DO-204AL axial-lead package.This diode has been designed for use in low-voltage applications, with peak repetitive reverse voltage up to 200V and average forward current of 4A. The features of this diode, such as its low forward voltage drop, fast switching and low stored charge, make it suitable for use in line regulation, free-wheeling, and wave shaping circuits.

The SCBK4F is a standard four-pin diode, with the anode terminals A and B connected to the positive side of the circuit and the cathode terminals C and D connected to the negative side of the circuit. The maximum reverse voltage rating of the SCBK4F is 200V peak and its maximum forward current rating is 4A. In addition, the device offers reverse current leakage of up to 2mA and reverse recovery time of up to 60ns.

The SCBK4F is primarily designed for use in applications such as converting AC power to DC power and protecting against reverse currents. In the case of using it for AC to DC conversion, it has the advantage of providing full-wave rectification, which allows for a greater level of current flow than with one-way rectification. In addition, it can also be used for surge protection in forward mode, thus protecting against excessive current levels from entering the circuit from transistors and ICs.

The SCBK4F operates on the principle of rectification, which refers to the ability of a diode to pass only those signals in one direction while blocking signals in the opposite direction. This is achieved by allowing current to flow in one direction (i.e., the anode side) while blocking current in the opposite direction (i.e., the cathode side). This one-way behavior occurs because of the constructed junction of the SCBK4F which is composed of P-type and N-type semiconductor materials.

The construction of the junction of the SCBK4F is what enables its working principle of rectification. When the anode is biased to a positive voltage and the cathode to a negative voltage, the junction is reversed biased. As a result, electrons flow from the anode side to the cathode side and holes flow from the cathode side to the anode side, thus allowing current flow in only one direction. When the junction is forward biased (i.e., the anode is biased to a negative voltage and the cathode to a positive voltage), the opposite occurs and current is allowed to flow in both directions. It is this behavior which allows the SCBK4F to be used as a bridge rectifier diode.

The SCBK4F is typically used in a variety of applications, such as converting AC power to DC power, protecting against reverse currents, and surge protection in forward mode. Its features, such as its low forward voltage drop, fast switching and low stored charge, make it suitable for use in these applications. Additionally, its one-way rectification principle allows for greater levels of current flow than with one-way rectification. With its wide range of features and application fields, the SCBK4F is a popular choice for many electronics projects.
