Thyristors, commonly referred to as SCRs (silicon-controlled rectifier), are electronically activated switches, and these devices are widely used in the industrial and domestic market. The VS-ST103S04PFL0P is an SCR from a renowned supplier of semiconductor products, and is a great choice for applications requiring a low-voltage and high temperature rating.
An SCR is four-layer semiconductor device, made of three P-N junction layers and a gate, also known as the control electrode. The pn junction layers are formed by mixing n-type and p-type semiconductor material. In the closed, or on, state of the device, current can pass through the device, and the voltage across it remains steady. Depending upon the type of SCR selected, current ratings may range from tens of milliamperes to hundreds of amperes throughout its intended operating temperature.
The practical working principles of the VS-ST103S04PFL0P can further be understood by examining its electric circuit symbol:
The electric circuit symbol of an SCR can be divided into three parts clearly: Anode (A), Cathode (K) and Gate (G). Only when VAK is positive with respect to VGK and VAK is larger than or equal to VAK(hold). then SCR can be conducting. Otherwise, SCR will turn to be non-conducting.For VS-ST103S04PFL0P, VAK(hold) is 7Vmin.
The VS-ST103S04PFL0P has a trigger current of 30mA and an overload current of 350mA. Using a variable power supply source a steady voltage of 7V can be maintained across VAK and VGK. If a current source of 30mA is applied to the Gate G, a voltage drop of 7V can be observed across the load at the anode (A). The SCR can be triggered on and conduction of the current becomes possible in a single direction from Cathode (K) to Anode (A).
Transient responses of the VS-ST103S04PFL0P can be tested by applying alternating current to its gate with a given frequency. This can help evaluate better its on-state characteristics with respect to different firing angles in various applications, such as induction heating, furnace controllers, rectifiers, phase control, etc.
The breakdown voltage rating of the VS-ST103S04PFL0P is 600V and it can also operate automatically in high power AC loads. Furthermore, its temperature coefficients are quite low, it has low leakage current, and it can be used in pulse control of AC and DC. Beyond this range, it can also be thought of for motor control, over-voltage protection, lighting control and toggling AC and DC switches for electronic design.
To summarize, the VS-ST103S04PFL0P is an ideal SCR for low-voltage and high temperature applications. It has a wide range of applications, from motor control and lighting control, to over-voltage protection and pulsed control. Its breakdown rating and temperature coefficients make it suitable for use in both AC and DC circuits. The gate voltage and current ratings of the VS-ST103S04PFL0P are also suitable for various industrial and domestic applications.
