VSKT250-14

The VSKT250-14 is a Silicon Controlled Rectifier (SCR) module intended for use in a wide range of applications. It is designed to provide the optimal combination of voltage and current ratings, device size, and operating temperature ranges for the most commonly used applications.

The VSKT250-14 is a four-pin, single-phase thyristor module consisting of four individual SCRs in a single package. The SCRs are connected in series and the four leads are connected to each of the SCRs. The VSKT250-14 SCRs are designed to switch a large amount of current, up to 250A, with low on-state voltage drops, making them suitable for switching power supplies in a range of applications.

The VSKT250-14 is a turn-off (or latching) thyristor module, meaning that it stays in an on state until a voltage is applied to the gate terminal, at which point the thyristor turns off. This makes the VSKT250-14 suitable for a range of applications, including battery chargers, renewable energy systems, and uninterruptible power supplies.

The key features of the VSKT250-14 include a maximum voltage rating of 1400VAC, a maximum intermittent current of 250A, a low on-state voltage drop of 1.2 V, and a junction temperature of -40°C to 135°C. The device can be used in a wide range of applications and the operating temperature range ensures reliable operation in demanding environments.

The working principle of the VSKT250-14 is based on the four individual SCRs that are internal to the device. The SCRs are connected in series and can provide control for up to 250A of current. When a voltage is applied to the gate terminal, the SCR turns off and no current is conducted through the device. This is the turn-off, or latching, operation of the VSKT250-14.

The VSKT250-14 can be used in a range of applications, including those requiring high levels of current switching. In particular, the device is well suited for battery chargers, renewable energy systems, and uninterruptible power supplies, due to its ability to provide control for up to 250A of current with a low on-state voltage drop. The device is also suitable for a range of industrial applications, such as welding, due to its capability to operate in demanding temperature ranges.
