| (R) T2550H-600T HIGH TEMPERATURE TRIAC FOR HOT APPLIANCES MAIN FEATURES : HIGH JUNCTION TEMPERATURE: Tj (MAX) = 150C IT(RMS) = 25 A VDRM/VRRM = 600 V SENSITIVITY : IGT (MAX) = 50mA DESCRIPTION Specifically developed for use in high temperature and harsh environments, the T2550H-600T triac is perfectly suited to driving heating elements found in hot appliances such as ovens, electric ranges or halogen ranges. The T2550H-600T, which is specified for use in temperature up to Tj = 150 C, offers the additional benefit of improved thermal resistance (1 C/W). Thanks to this feature, heatsink dimensionning can be optimized to suit typical conditions in such applications. The devices surge features, which have proven to be highly performing, ensure safe operation under peak inrush current conditions for example, in halogen ranges.
