Alternistor triacs operate at up to 150°C
With a maximum junction temperature of 150°C, the 16A QJxx16xHx series and 25A QJxx25xHx series are designed for use as AC switches, helping circuit designers address overheating challenges in AC power control applications with limited or no heat sinking. Their high peak, single cycle AC current pulse ratings allow them to tolerate higher in-rush currents in heater or motor control applications. The devices come with 200A/250A ITSM ratings, allowing designers to tolerate higher inrush currents in heater or motor control applications. The devices are offered in mechanically and thermally robust TO-220/263 (16A and 25A) packages and a TO-218 (25A) clip-attach assembly for higher field reliability than wire-bond packages. Internally isolated TO-220 and TO-218 packages provide better heat dissipation and higher isolation voltage.
