BTA425X-800B

Planar passivated high commutation three quadrant triac in a SOT186A (TO-220F) "full pack" plastic package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This "series B" triac will commutate the full rated RMS current at the maximum rated junction temperature without the aid of a snubber.

Features and Benefits
  • 3Q technology for improved noise immunity
  • High immunity to false turn-on by dV/dt
  • High minimum IGT for guaranteed immunity to gate noise
  • High voltage capability
  • Isolated mounting base package
  • Least sensitive gate for highest noise immunity
  • Planar passivated for voltage ruggedness and reliability
  • Triggering in three quadrants only
  • Very high commutation capability with maximum false trigger immunity
Applications
  • Electronic thermostats
  • Heating control
  • High power motor control
  • High power switching
