BTA412Y-800B

Planar passivated high commutation three quadrant triac in a SOT78D (TO-220AB) internally insulated 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 RMS current at the maximum rated junction temperature without the aid of a snubber. This device has high Tj] operating capability and an internally isolated mounting base.

Features and Benefits
  • 3Q technology for improved noise immunity
  • High commutation capability with maximum false trigger immunity
  • High surge capability
  • High Tj(max)
  • Isolated mounting base with 2500 V (RMS) isolation
  • Least sensitive gate for highest noise immunity
  • Planar passivated for voltage ruggedness and reliability
  • Triggering in three quadrants only
  • Very high immunity to false turn-on by dV/dt
Applications
  • Electronic thermostats (heating and cooling)
  • High power motor controls
  • Rectifier-fed DC inductive loads e.g. DC motors and solenoids
