non-zero-crossing silicon bilateral TRIAC and a main
output power TRIAC. These devices isolate low
voltage logic from 115/240 VAC lines to provide
random phase control of high current TRIACs or
thyristors. These devices feature greatly enhanced
static dv/dt capability to ensure stable switching
performance of inductive loads.
