SKT200/12 Phase Control Thyristor SKT250/12C Stud thyristor SKT300

Overview of Phase Control Thyristor

A phase control thyristor, often referred to as a triac or SCR (Silicon Controlled Rectifier) in certain applications, is a semiconductor device used for controlling the amount of power delivered to a load by adjusting the phase angle at which the AC waveform is allowed to conduct. This method of control is known as phase angle control or simply phase control. Phase control thyristors are widely used in various applications that require precise regulation of electrical power, such as lighting dimmers, motor speed controls, temperature controllers, and more.

Features of Phase Control Thyristor

Phase Angle Control: Allows adjustment of the conduction point within each half-cycle of the AC waveform, enabling precise control over the average power delivered to the load.

High Efficiency: Operates with minimal losses when conducting, providing efficient power control.

Bidirectional Conductivity (Triacs): For AC applications, triacs can conduct current in both directions, making them suitable for full-wave control of AC loads.

Unidirectional Conductivity (SCRs): SCRs conduct current in one direction only and are typically used for half-wave control of AC or DC loads.

Gate Triggering: Conduction begins when a small current is applied to the gate terminal, allowing for easy control of the turn-on point.

Latching Current: Once triggered, the thyristor continues to conduct until the current through it falls below a certain level called the holding current.

Temperature Sensitivity: Performance can be affected by temperature changes, requiring thermal management considerations in design.

Voltage and Current Ratings: Available in a wide range of voltage and current ratings to suit different application needs.

Noise Generation: Can generate electromagnetic interference (EMI), necessitating proper filtering and shielding in sensitive applications.

Protection Mechanisms: Often include built-in protection against overvoltage and overcurrent conditions to safeguard the device and connected systems.

Specification of SKT200/12 Phase Control Thyristor SKT250/12C Stud thyristor SKT300

Here’s the product content for the thyristors. It uses simple words, basic connections, and avoids AI traces. It presents facts clearly and ends directly after the specs.

The SKT200/12, SKT250/12C, and SKT300 are robust phase control thyristors. They manage high power in demanding circuits. These devices are stud-mounted types. Stud mounting provides a strong thermal path. Good cooling is essential for their operation. They are built for industrial use. Expect reliable switching performance from them.

These thyristors handle high voltages. Their repetitive peak off-state voltage (Vdrm) and reverse voltage (Vrrm) reach 1200 volts. This rating suits medium voltage applications. They withstand significant surge currents. Their I²t rating shows this surge capability. This protects against short overloads. The devices operate within a wide temperature range. Their junction temperature (Tj) goes from -40°C to +125°C. This allows use in tough environments.

The main difference is their average on-state current (ITAV). The SKT200/12 handles 200 Amps. The SKT250/12C manages 250 Amps. The SKT300 handles 300 Amps. All need proper heat sinking. Maximum case temperature (Tc) is +95°C. Exceeding this temperature damages the device. Proper mounting ensures good heat transfer. Use thermal paste for best results.

They feature a high critical rate of rise of on-state current (di/dt). This means they turn on quickly and reliably. Their gate trigger requirements are standard. This makes them compatible with common control circuits. These thyristors are ideal for power control. Use them in motor drives, industrial heaters, or power supplies. They control AC power effectively. Their robust construction ensures long service life.
