BTA420-800BT

Planar passivated high commutation three quadrant triac in a SOT78 (TO-220AB) plastic 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
  • 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
  • High voltage capability
  • Least sensitive gate for highest noise immunity
  • Planar passivated for voltage ruggedness and reliability
  • Triggering in three quadrants only
Applications
  • Applications subject to high temperature
  • Heating controls
  • High power motor control
  • High power switching
