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 ...

Promising to simplify solid-state relay, ac-motor control, and lighting ballast designs, the FOD420 and FOD4208 random-phase, snubber-less triac drive optocouplers integrate active dv/dt clamps to ...

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 ...

Peter Green explains advantages of LED drivers based on the flyback power-supply topology: They're inexpensive; they provide an isolated output that complies with UL safety requirements; they make it ...

As with the age-old panic after realizing you have left an oven on, a cand le lit, and so on, a soldering tool left on is a potentially serious hazard. Hackaday.io user [Nick Sayer] had gotten used to ...
