BTA208-800B

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 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 commutation capability with maximum false trigger immunity
  • High immunity to false turn-on by dV/dt
  • High voltage capability
  • Less sensitive gate for very high noise immunity
  • Planar passivated for voltage ruggedness and reliability
  • Triggering in three quadrants only
Applications
  • Electronic thermostats
  • General purpose motor controls
  • Rectifier-fed DC inductive loads e.g. DC motors and solenoids
