Diodes Incorporated AH3781-SA-7 is a Hall Effect latching digital switch designed for surface mount applications. This component features an open-drain output and is optimized for sensing the south pole of a magnetic field with typical trip and release points of 4mT. The device operates from a wide 3V to 28V supply voltage range, drawing a maximum of 5.8mA, and can provide an output current up to 60mA. Built with temperature compensation, the AH3781-SA-7 maintains reliable performance across an operating temperature range of -40°C to 125°C. Packaged in a compact SOT-23-3 (TO-236-3, SC-59) configuration, it is supplied on tape and reel. This Hall Effect switch is suitable for applications in automotive, industrial, and consumer electronics requiring non-contact position sensing and latching functionality.
