HMHA281R4

The On Semiconductor HMHA281R4 is an optoisolator designed for signal isolation applications. This component is RoHS3 compliant, indicating adherence to environmental standards for hazardous substances. It features an MSL (Moisture Sensitivity Level) of 1 Unlimited, meaning it has a very low risk of moisture absorption during handling and assembly. The REACH status is listed as Unaffected, suggesting it does not contain substances of very high concern under REACH regulations.

As a transistor, photovoltaic output type optoisolator, the HMHA281R4 facilitates the transfer of signals between circuits while providing electrical isolation. Specific electrical characteristics such as isolation voltage, channels, and transfer ratios are not detailed in the available data but are critical for design considerations. The component's packaging and mounting type would also be important factors for integration into electronic systems.

This optoisolator is part of the broader category of isolators, specifically designed for applications requiring a high degree of electrical separation between input and output stages. Its compliance with RoHS3 and its MSL 1 rating make it a consideration for designs where environmental impact and assembly process sensitivity are important.
