Introduction

The S2K-13-F (silicon controlled rectifier bridge) is a single diode rectifier suitable for use in medium power applications. It is a low cost and efficient way to regulate power in electrical circuits. The S2K-13-F is part of a family of rectifiers which includes the more common S2K-08-F and S2K-11-F.

Application Field

The S2K-13-F is designed for use in low power applications, typically those requiring a maximum current (mA) rating of 500mA or less. Typical applications include cell phone chargers, low-power UPS systems, small motor control circuits, and automotive and industrial motor DC to AC inverters.

Working Principle

The S2K-13-F operates on the principle of resistive switching. This is a technology where an inverse voltage is applied to the input of the bridge circuit in order to switch it on or off. This allows the power in the circuit to be regulated.The resistor in the circuit controls the current through the bridge. When the resistance is high, the current will reduce and the circuit will be in an ‘off’ state. Conversely, when the resistance is low, the current will increase and the circuit will be in an ‘on’ state. On a simple level, the resistor in the bridge controls the current ‘switching’ on and off, which in turn controls the power in the circuit.

Component Design and Physical Structure

The S2K-13-F is constructed using Silicon, a more robust and reliable material than the leaded counterparts. The S2K-13-F features four terminals and two terminals for the power input. It has an internal heat sink to dissipate unwanted heat from the bridge’s operation. The bridge has an operating temperature range of -40 to 105°C, a storage temperature range of -40 to 120°C and its peak reverse voltage is 150V.

Conclusion

The S2K-13-F is a versatile, low cost, and efficient rectifier. It is a suitable option for low power applications with a maximum current (mA) rating of 500mA orless. The S2K-13-F enables resistive switching which results in robust and reliable power regulation. With its four terminal connections, internal heat sink and operating temperature range, it is the ideal rectifier for a wide range of applications.
