TYN30Y-800T Silicon Controlled Rectifier WeEn Semiconductors TYN30Y-800T Silicon Controlled Rectifier (SCR) is a planar passivated rectifier with high blocking voltage capability, available in an IITO220 package. This SCR features high inrush current, high thermal cycling performance, and high junction temperature. The TYN30Y-800T SCR includes AC power control, high immunity to false turn-on, and internally isolated mounting base. This SCR offers 19A average on-state current, 800V repetitive peak reverse voltage, and 20W peak gate power. The TYN30Y-800T SCR operates at -40°C to 150°C temperature range and 150°C maximum junction temperature. This SCR is ideal for use in Capacitive Discharge Ignition (CDI), crowbar protection, inrush protection, motor control, and voltage regulation.
