This universal triac controller circuit with optocoupler solves the problem that triacs have when functioning at low temperatures (triac needs higher gate current) by adding a transistor at the output ...

The zero-crossing FOD410 triac-driver optocoupler series eliminates the RC-snubber network when driving a snubberless discrete power triac, reducing the board space and energy required to power the ...

Würth Elektronik has created a range of opto-isilated triacs for controlling light AC loads and larger triacs. They are called WL-OCTR, and come in a choice of packages: through hole DIP-4 or DIP-6, ...

Vishay has introduced DIP-6 and SMD-6 opto-triacs rated at 800V 100mA for home appliances and industrial equipment. Applications include controlling small loads and triggering large triacs – in ...

The flyback converter topology includes an electromagentic interference filter and rectifier, a MOSFET switch, a rectifier diode, and an opto-isolator. They provide an inexpensive, efficient, and safe ...
