Planar passivated four quadrant triac in a SOT1292 (IITO3P) package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This triac will commutate the full RMS current at the maximum rated junction temperature (Tj(max) = 150 °C). It is used in applications where "high junction operating temperature capability" is required.

Features and Benefits
• High current TRIAC
• Low thermal resistance
• High junction operating temperature capability (Tj(max) = 150 °C)
• High voltage capability
• Planar passivated for voltage ruggedness and reliability
• Insulated tab rated at 2500 V rms
• High current / high surge applications
• High power / industrial controls -- e.g. heating, motors, lighting
