Vishay General Semiconductor - Diodes Division IRKT71-12A is a high-performance SCR module featuring a series connection of one SCR and one diode. This component offers a blocking voltage of 1.2 kV and a continuous on-state current rating of 75 A (average) and 165 A (RMS). The device supports a non-repetitive surge current of up to 1740 A at 60 Hz. With a gate trigger current (Igt) of 150 mA and a gate trigger voltage (Vgt) of 2.5 V, it is designed for efficient triggering. The hold current (Ih) is rated at 200 mA. The IRKT71-12A utilizes the ADD-A-PAK (3 + 4) package for chassis mounting, facilitating effective thermal management. Operating across a temperature range of -40°C to 125°C, this module finds application in industrial power control systems, motor drives, and welding equipment.
