Planar passivated high commutation three 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 "series BT" triac will commutate the full RMS current at the maximum rated junction temperature (Tj(max) = 150 °C) without the aid of a snubber. It is used in applications where "high junction operating temperature capability" is required.

Features and Benefits
  • High current TRIAC
  • 3Q technology for improved noise immunity
  • High commutation capability with maximum false trigger immunity
  • High immunity to false turn-on by dV/dt
  • High junction operating temperature capability (Tj(max) = 150 °C)
  • High voltage capability
  • Least sensitive gate for highest noise immunity
  • Low thermal resistance
  • Planar passivated for voltage ruggedness and reliability
  • Triggering in three quadrants only
  • Insulated tab rated at 2500 V rms
  • Applications subject to high temperature (Tj(max) = 150 °C)
  • High current / high surge applications
  • High power / industrial controls - e.g. heating, motors, lighting
