MOC3011VM is a normally open and zero voltage turn on Optoisolators - Triac, SCR Output, which are often used for triggering, phase control and many other applications. It is a very reliable device that offers low operating current and is designed specifically for applications in high voltage and current.

Application Field

MOC3011VM is typically used for applications in high voltage and high current. This includes motor control applications, phase control, AC/DC conversion switching, and other related applications. It can also be used for making pulse generation circuits, in which it can be used as a series switch.

The device is widely used for applications like solar panels, motor drivers, flyback converters, motor controllers, latching relays, linear and switching power supplies, rectifiers, voltage regulators, LED lighting, and electro-mechanical switches. It offers very good AC voltage and current handling, so it is suitable for many applications.

Working Principle

MOC3011VM works based on the principle of optically isolated triac. It consists of an LED light source, a photocoupler, and a triac. The photocoupler has an isolated input and a triac output. The LED is used to transmit light. The coupling element transfers the input voltage to the triac.

When the input voltage is greater than the forward voltage of the LED, it will turn on the LED, which will then emit light and turn on the triac. The output current of the triac will then be equal to the input current, multiplied by the current gain of the optical coupler. This can be used to control the speed of the motor, as well as switching on and off the AC power.

MOC3011VM is also capable of generating a short-duration pulse, which can be used to trigger other devices. This feature is useful in applications like pulse start and pulse width modulation (PWM). It also provides a low leakage current and low capacitance, which is beneficial when used in high frequency applications.
