BTA208S-800B
3Q Hi-com Triac
11 October 2016 Product data sheet
1. General description
Planar passivated high commutation three quadrant triac in a SOT428 (DPAK) surface mountable
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.
2. 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
• Surface mountable package
• Triggering in three quadrants only
3. Applications
• Electronic thermostats
• General purpose motor controls
• Rectifier-fed DC inductive loads e.g. DC motors and solenoids
