It combines a molded optical coupler and an integrated triac for direct interfacing with AC lines. The device offers a wide input-to-output transient immunity, with a minimum of 1500 Vrms for up to 2 minutes. It has excellent high temperature stability and repeatability as well as a high common mode transient immunity rating of up to 2,500 V/μs.Features
The MOC3081FR2VM has a wide range of advantages. It offers LED indicator protection from short circuit and transient conditions, making it very durable for use in harsh environments. It also offers a wide operating temperature range from -40 °C to 85 °C, which gives it great flexibility for a wide variety of applications. Additionally, it has a high common mode transient immunity rating up to 2,500 V/μs and excellent high temperature stability and repeatability. It is used in a variety of applications, such as power supplies, motor control, heating systems, and inverters.Applications
The MOC3081FR2VM is commonly used in a variety of applications, including power supplies, motor control, lighting systems, and inverters. In power supplies, it has a low-power bidirectional thyristor switch, allowing for both AC and DC control. In motor control, it is used to protect the circuit from transient and over-voltage conditions. It is also commonly used as a temperature controller in heating systems. In inverters, it combines its isolated input and output for high efficiency, as well as its high isolation voltage rating for surge protection.Working Principle
The MOC3081FR2VM works on the principle of opto-isolation when combined with a triac and SCR (silicon control rectifier) output. An LED emitter at the input side of the device emits a light pulse which is received by a photodiode at the output side of the device. This pulse, when received, triggers the gate of the output side device, which in turn triggers the triac or SCR. This activates the load to the desired effect. The opto-isolator also serves to protect the circuit from transient and over-voltage conditions.Conclusion
The MOC3081FR2VM is an opto-isolator that can be used for applications involving triac and SCR outputs. It offers excellent temperature stability and common mode transient immunity ratings as well as wide operating and input-to-output ranges. It is commonly used in a variety of applications, such as power supplies, motor control, heating systems, and inverters. Its working principle is based on the principle of opto-isolation, with an LED emitter sending a light pulse to a photodiode, which triggers the gate of the output side device, activating the load.
