Diacs are bidirectional diodes that switch AC voltages and trigger silicon controlled rectifiers (SCRs) and triacs. SCRs are four-layer (PNPN) thyristors with an input terminal (gate), an output ...

Description: Teccor brand Quadrac devices are triacs that include a diac trigger mounted inside the same package. This device, developed by Littelfuse, saves the user the expense and assembly time of ...

Diacs and triacs are often used for control of ac lines and are seeing increasing use in Internet-enabled line switches. However, the traditional approach of modeling them using bipolar transistors ...

This SCR phase control works much like the common TRIAC dimmer, but has numerous advantages including increased current capability, robustness and absence of minimum voltage “snap-on.” A complementary ...
