Thyristors - SCRs

The S6004VS2 is a silicon-controlled rectifier (SCR) that is typically used in AC applications to control motor speed, energy control, load and lamp dimming, heating control and AC motor startup and speed control. As a four terminal device composed of a PNPN element, SCRs are semiconductor switches that can be turned on and off with a single triggering circuit, and they remain in the "on" position until the current drops to zero.

The S6004VS2 is a 4-pin 600V 25A SCR with a zero current threshold and can handle a surge of up to 70A peak. It is built with an industrial-grade aluminum nitride base comprising two layers with a high dielectric strength, and is designed for extreme environments in which temperature and pressure are fluctuating. It\'s also IP67-rated and hermetically sealed for dust, moisture, and other environment contaminants.

Application Field

The S6004VS2 is designed for use in applications requiring high power with medium-voltage operation. It is used for soft start and speed control of motors, lighting circuits and dimmers, power factor correction and as an auxiliary switch in various AC switching/protection devices. It is also used in DC circuits for battery charging and other applications requiring high power control.

The S6004VS2 is well-suited to applications in any industry due to its high power capability, small size, and low power consumption. It is the perfect choice for applications including industrial equipment, elevators, agriculture equipment, motor speed control, packaging and food processing, HVAC systems, etc.

Working Principle

The S6004VS2SCR is triggered by a current pulse when VAK reaches the triggering voltage, thus turning on the SCR. The current pulse is converted to a voltage across the control electrode, which is usually monitored by a sensing circuit connected between the gate and cathode terminals. Once triggered, the SCR will remain in its non-conductive state until the current drops to zero, at which point it will be turned off. In addition, the S6004VS2 has a fast turn-on speed and a low gate current, making it well-suited for use in applications requiring high power operation with a small form factor.

Due to its low threshold voltage and fast turn-on time, the S6004VS2 can control heavy AC loads without the need for isolation devices. The SCR also offers superior thermal and electrical isolation, allowing it to be used in applications where noise and ground loops must be minimized.

The S6004VS2 is a highly reliable and efficient switching device, making it a great choice for applications requiring fast and reliable control of high-power AC loads. Its wide operating range and hermetic construction also ensure that it can stand up to any environmental conditions it may be exposed to.
