ONSEMI 4N38SR2M High Voltage Phototransistor Optocoupler

The ONSEMI 4N38SR2M, along with the H11D1M, H11D3M, and MOC8204M, are phototransistor-type optically coupled optoisolators. These devices utilize a gallium arsenide infrared emitting diode paired with a high-voltage NPN silicon phototransistor, housed in a standard plastic six-pin dual-in-line package. They are commonly employed in power supply regulators, digital logic inputs, appliance sensor systems, microprocessor inputs, and industrial controls, providing robust electrical isolation and signal transmission. The device offers high voltage capabilities and safety regulatory approvals, making it suitable for a wide range of industrial applications.
