Thyristors – SCRs are solid state switches used in high power applications. Thyristors are commonly used in electric motor drives, heating systems and various industrial processes. The S2010LS3 is a part of the popular Small Body Silicon Controlled Rectifier (SCR) family from Vishay Semiconductor. This SCR is capable of blocking up to 1,400 Volts, with a surge capability of up to 8,000 Volts. It is commonly used in low inductance and high inrush current AC switching applications.

The S2010LS3 is a very fast switching device with a typical commutating time of 60 ns maximum. It can be triggered by either gate current or gate voltage. The gate triggering requirements are very low, with a gate current of only 5 mA and gate voltage of 4.0 V or less required for switching. The typical gate triggering power is about 5 to 6 mW. The maximum gate triggering voltage for the S2010LS3 is +20 V. It is an open type SCR, which means that the gate lead is not connected to the cathode and must be driven with an external supply.

The S2010LS3 is used in AC line current sensing applications where very fast response is required. The low firing current and low triggering power requirements of the S2010LS3 make it well suited for these applications. It is also suitable for low frequency applications such as lamp dimmers and speed control circuits. The high surge capability and low switching loss make it very suitable for power conversion applications. The S2010LS3 is also very suitable for applications such as lighting control and AC supervisory circuits, as well as welding and certain DC applications.

The working principle of the S2010LS3 is based on the four layer thyristor structure. It consists of three anodes, one cathode and a gate. When the anode current is applied, the thyristor will conduct in the forward direction, allowing the current to flow from the anode to the cathode. When the gate is triggered, the thyristor will be turned on. The gate current, or voltage, is used to control the on-off state of the thyristor. When the gate pulse is removed, the thyristor will turn off automatically after a predetermined time.

The S2010LS3 is a very versatile thyristor with a wide range of applications in various industrial and commercial applications. The low gate triggering power and short switching time make it an ideal solution for fast switching applications. The high blocking voltage and surge capability make it suitable for high power applications. It is also suitable for AC control applications such as lamp dimmers and AC supervisory circuits. The low power losses and low firing current requirements make it very suitable for power conversion applications.
