Thyristors have been used in the electronics industry for many years in the form of Solid State Relay (SSR). These solid state devices have been gaining popularity due to their reliability and low power consumption as compared to their mechanical counterparts. The SCR (Silicon-Controlled Rectifier) is a three-terminal device, whose voltage drop across it can be adjusted by the application of bias voltage to the gate. SCRs are commonly used for controlling large electric currents. The VS-2N688 is a popular Thyristor which has been designed for usage in the industrial, telecom and automotive sectors. This article will discuss the application fields and working principle of VS-2N688.

The VS-2N688 is an SCR with a Repetitive Peak Off-state Voltage of 600V and Repetitive Peak On-state Current of 8A. This Thyristor is used in control applications such as motor control, relay, lamp, HVAC control, air conditioner and electric welding. As the SCR remains in an OFF-state until bias voltage is applied to the gate terminal, it is ideal for systems that require precise timing and control. This Thyristor is also often used in applications which require several SCRs to be gated in sequence in order to control the switching of current.

The working principle of the VS-2N688 depends on the basic properties of the SCR. The three terminals (Anode, Cathode and Gate) of the SCR can be thought of as two diodes connected in opposite directions. When the anode is connected to the cathode and forward bias is applied, the SCR remains in an OFF-state. In this state, current does not flow through the SCR until bias voltage is applied to the gate. When a positive voltage is applied to the gate terminal, the SCR switches to the ON-state, allowing current to flow through the device. The SCR will remain in the ON-state until the gate voltage is removed, or until the current through the SCR falls below a certain threshold. This property makes SCRs ideal for controlling large electric currents.

The VS-2N688 can be used in a variety of control applications due to its low power consumption and its ability to control large electric currents. Its ability to remain in an OFF-state until gate voltage is applied makes it ideal for precise timing and control. Its two diodes connected in opposite directions make it resistant to high voltage and electrical noise, making it suitable for use in industrial, telecom and automotive sectors. This Thyristor is a popular choice due to its reliability and its ability to be gated in sequence in order to control the switching of current.

In conclusion, the VS-2N688 is a popular Thyristor which has been designed for usage in the industrial, telecom and automotive sectors due to its low power consumption and reliability. It\'s Repetitive Peak On-state Current of 8A and its ability to remain in an OFF-state until bias voltage is applied to the gate terminal make it ideal for precise timing and control. The two-diode design of the SCR also makes it resistant to high voltage and electrical noise. This makes it a popular choice for applications which require several SCRs to be gated in sequence in order to control the switching of current.
