BTA316-800CT
3Q Triac
Rev.01 - 26 September 2017 Product data sheet
1. General description
Planar passivated high commutation three quadrant triac in a SOT78 plastic package intended for
use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This "series CT" triac
will commutate the full RMS current at the maximum rated junction temperature (T
j(max)
= 150 °C)
without the aid of a snubber. It is used in applications where "high junction operating temperature
capability" is required.
2. Features and benets
• 3Q technology for improved noise immunity
• High commutation capability with maximum false trigger immunity
• High junction operating temperature capability (T
j(max)
= 150 °C)
• 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
3. Applications
• Applications subject to high temperature (T
j(max)
= 150 °C)
• Electronic thermostats (heating and cooling)
• High power motor controls e.g. washing machines and vacuum cleaners
• Rectier-fed DC inductive loads e.g. DC motors and solenoids
