Vishay General Semiconductor - Diodes Division presents the IRKH91-08A, a high-performance SCR module designed for demanding power control applications. This module features a series connection of an SCR and a diode, operating at an off-state voltage of 800V. With an average on-state current of 95A and an RMS on-state current of 210A, it is suitable for power factor correction, motor control, and high-power switching systems. The device exhibits a gate trigger current (Igt) of 150mA and a hold current (Ih) of 250mA. It boasts a non-repetitive surge current (Itsm) of up to 1870A. The IRKH91-08A utilizes the ADD-A-PAK (3 + 2) package for chassis mounting, facilitating efficient thermal management. Operating temperature ranges from -40°C to 125°C. This component is widely employed in industrial power supplies, welding equipment, and renewable energy systems.
