Vishay Medium Power Phase Control Thyristor 1200 V 40 A 60 mA 440 A 1.7 V VS-25RIA120M

Vishay VS-25RIA120M is a medium power phase control Thyristor designed for applications requiring reliable and controlled rectification at voltages up to 1200 volts and currents of 40 amperes. This device is encapsulated in a TO-48 stud mount package, facilitating easy installation and efficient heat transfer in industrial circuits.

This silicon-controlled rectifier (SCR) features a low peak on-state voltage of 1.7 V, which minimizes conduction power losses during operation, and a surge current rating of 440 A that provides robustness to electrical stresses typical in power regulation systems such as battery chargers, welders, and controlled power supplies.

The maximum gate trigger current of 60 mA and maximum holding current of 130 mA ensure stable and precise control of the conduction phase angle, vital for speed and temperature control circuits. Its operating temperature range from -65°C to 125°C allows deployment in demanding ambient conditions.

Compliant with RoHS standards, the device supports environmentally conscious designs. Typical applications include motor speed regulation, temperature control in industrial equipment, and power conditioning systems requiring phase control for efficient power delivery.

Silicon Controlled Rectifier with four-layer alternating N and P-type materials for bistable switching. Encapsulated in TO-48 package for stud mounting and mechanical robustness. Capable of handling repetitive peak off-state currents of 10 mA for noise immunity.

Maximum gate trigger voltage rated at 2 V for effective triggering control. Suitable for use in battery chargers, welders, plating equipment, regulated power supplies, and motor speed controllers.

This product is essential for industrial automation, power electronics, and semiconductor markets requiring medium power SCR components with proven reliability. Explore Vishay semiconductor products for your phase control and power regulation needs at EnvMart.
