Оптопара с симисторным выходом MOC3063 - Mini-Tech
The is a 6-pin optocoupler (opto-triac) that allows low-voltage logic systems, such as microcontrollers, to safely control high-voltage AC loads. Its defining feature is Zero-Crossing detection , which ensures the triac only switches on when the AC voltage is near zero, significantly reducing electrical noise and electromagnetic interference. Typical Application Circuits shemy na moc3063
: The output pins (4 and 6) are connected to the Gate and Main Terminal 2 (MT2) of a larger triac, such as the BT139. : To protect against sudden voltage spikes and
: To protect against sudden voltage spikes and false triggering, a snubber network (usually a 39 Ωcap omega resistor and a 0.01 F capacitor) is often placed across the main triac. such as microcontrollers
The most common use of the MOC3063 is as a driver for a powerful external triac.
: A typical circuit connects a microcontroller output (through a current-limiting resistor) to the internal LED of the MOC3063 (pins 1 and 2).
