Manufactured by ON Semiconductor, this 6-pin DIP IC contains a gallium arsenide infrared emitting diode optically coupled to a non-zero-crossing silicon bilateral voltage switch (triac driver).\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, the MOC3052 is specifically designed to drive larger power TRIACs (like the BT136 or BTA16) to control 110V\/220V AC loads. Because it is a \"random-phase\" (non-zero crossing) driver, it allows you to trigger the AC waveform at any point in its cycle. This makes it the perfect choice for building custom AC light dimmers, motor speed controllers, and phase-control circuits using microcontrollers like Arduino or ESP32, while ensuring your delicate logic boards are completely electrically isolated from deadly AC voltages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDatasheet:\u003c\/strong\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/MOC3052M-D.PDF?v=1784185623\" target=\"_blank\" rel=\"noopener\"\u003eClick here to view\/download the MOC3052 Datasheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e moc3052 ic, random phase optocoupler, triac driver ic, ac dimmer optoisolator, on semi moc3052, dip-6 optocoupler.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIC Number:\u003c\/strong\u003e MOC3052\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e ON Semiconductor (ON)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e 6-Pin DIP (Through-Hole)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Type:\u003c\/strong\u003e Photo-Triac (Random Phase \/ Non-Zero Crossing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak Blocking Voltage:\u003c\/strong\u003e 600V (Suitable for 110V and 220V AC mains)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED Trigger Current (Ift):\u003c\/strong\u003e 10mA (Typical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation Voltage:\u003c\/strong\u003e 4170V AC (RMS)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Light Dimmers:\u003c\/strong\u003e Building custom phase-cutting dimmer circuits for incandescent bulbs or AC LED fixtures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Speed Control:\u003c\/strong\u003e Adjusting the speed of AC fans, drills, or pumps by chopping the AC waveform.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid State Relays (SSR):\u003c\/strong\u003e Designing custom DIY solid-state relays for switching high-power AC loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Controls:\u003c\/strong\u003e Safely interfacing low-voltage PLCs and microcontrollers with high-voltage solenoid valves and contactors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the MOC3052 drive an AC appliance directly?\u003c\/strong\u003e\u003cbr\u003eA: No. The MOC3052 is only a triac \u003cem\u003edriver\u003c\/em\u003e. It is designed to safely trigger a much larger, high-power TRIAC (such as a BTA16). Attempting to run a heavy AC load directly through the MOC3052 will instantly burn it out.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the MOC3052 and the MOC3041?\u003c\/strong\u003e\u003cbr\u003eA: The MOC3052 is a \"random-phase\" driver, meaning it can trigger at any point in the AC wave, which is required for dimming and speed control. The MOC3041 is a \"zero-crossing\" driver, which only switches ON when the AC wave hits zero volts. Zero-crossing is better for simple ON\/OFF switching (like a relay) because it produces less electrical noise, but it cannot be used for dimming.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a resistor on the input side?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The input side of the MOC3052 is essentially just an infrared LED. If you are driving it from a 5V Arduino pin, you must use a current-limiting resistor (typically around 220Ω to 330Ω) to prevent burning out the internal LED.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × MOC3052 Random-Phase Triac Driver Optocoupler IC (ON Semi)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ON Semiconductor","offers":[{"title":"Default Title","offer_id":48327897088238,"sku":"INC-01438","price":21.24,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/moc3052.jpg?v=1784185534","url":"https:\/\/www.tomsonelectronics.com\/products\/moc3052-random-phase-triac-driver-optocoupler-ic","provider":"Tomson Electronics ","version":"1.0","type":"link"}
