650V TRENCHSTOP™ IGBT6 and field-stop IGBTs Infineon Technologies 650V TRENCHSTOP™ IGBT6 and field-stop IGBTs are designed to meet specific requirements of motor drives in-home appliance fans, compressors, commercial sewing machines, and pumps. The 650V IGBTs have been optimized for the lowest switching losses, especially in systems with higher switching frequencies up to 30kHz. The IGBTs are co-packed with the soft, fast recovery Rapid 1 anti-parallel diode for the lowest total losses.
