VS-2N692

Thyristors - SCRs

SCRs are solid-state devices made from silicon compounds and are used in a variety of applications. A silicon-controlled rectifier (SCR), or thyristor, is a four-layer, semiconductor device that consists of a gate, an anode, a cathode, and a junction. SCRs work using a controlling gate current or voltage, allowing or inhibiting the passage of current from anode to cathode. The current or voltage applied to the gate determines whether the SCR is in an conducting mode or a non-conducting mode.

VS-2N692 Application Field

The VS-2N692 is a subminiature high current SCR, designed for use in a variety of applications. It has a low trigger current and a high gate sensitivity. It has a maximum ratings of 300V @ 150A, with a nominal on-state current of 10A. The VS-2N692 is used in alternating and direct current control applications, including motor control and power conversion.

VS-2N692 Working Principle

As explained earlier, SCRs are solid-state devices that are controlled by a current or voltage applied to the gate. When the gate current or voltage is applied, the current flowing from the anode to the cathode is allowed to pass through the SCR, effectively turning it on. When the gate current or voltage is removed, the SCR returns to its OFF state and the current flow is stopped. The SCR is said to be in a “holding state” when it is not conducting any current. The VS-2N692 SCR uses a low gate current and a high gate sensitivity to achieve a fast and efficient switching of the device.

The VS-2N692 can be used in a variety of applications, from motor control to power conversion. It is ideal for applications where a fast and efficient response is required, as it has a low trigger current and a high gate sensitivity. Its small size makes it easy to integrate into tight spaces and its high current rating makes it suitable for high power applications. The VS-2N692 is also designed to be resistant to surges and has built-in thermal, over-voltage and over-current protection.
