ON Semiconductor MOC3032SM Optoisolator

The MOC3032SM is a high-performance optically-coupled isolator produced by ON Semiconductor. It incorporates an infrared light-emitting diode (LED) and a silicon bilateral switch, which acts as a zero-crossing triac driver. This device is designed to facilitate the interfacing of electronic controls and power triacs to control resistive and inductive loads for 115 VAC operations.

Key Features

• Optical Isolation: The MOC3032SM offers an exceptional electrical isolation between input and output with an isolation voltage of 7500 V peak. This feature ensures safety and signal integrity, which is vital in high-voltage applications.
• Zero-Crossing Circuit: Its built-in zero-crossing circuitry guarantees that the triac is triggered only at the point of the AC wave where the voltage is near zero, reducing electrical noise and stress on the triac.
• High dv/dt Rating: The device can withstand high rates of voltage change, making it suitable for tough electrical environments.
• Compact 6-Pin DIP Package: The MOC3032SM comes in a small 6-pin DIP (Dual In-line Package) configuration, which is both space-efficient and easy to integrate into a variety of designs.

Applications

The MOC3032SM is ideal for controlling a wide range of loads such as motors, solenoids, high-current thyristors, and relays. It is commonly used in applications that require direct control by microprocessors or other low-voltage logic circuits, including:

• Industrial controls
• Office machines
• Motor controls
• Domestic appliances
• Vending machines

Technical Specifications

The MOC3032SM has a forward current of 60 mA, with a maximum trigger current of 15 mA for the triac driver output. The operating temperature range is from -40°C to +85°C, which allows it to function reliably in a wide range of environmental conditions.

ON Semiconductor's commitment to quality ensures that the MOC3032SM meets the stringent requirements of electronic control applications, providing designers with a robust, reliable, and efficient solution for isolating and controlling AC loads.
