Quality Control: Learn More
The onsemi HMHA2801AR4 is a single-channel, DC input optoisolator featuring a transistor output. This component offers an isolation voltage of 3750Vrms, making it suitable for applications requiring robust electrical separation. It supports a maximum forward DC current of 50mA and provides an output current of 50mA per channel. The current transfer ratio (CTR) ranges from a minimum of 80% at 5mA to a maximum of 160% at 5mA. The device operates with a typical forward voltage of 1.3V and a maximum collector-emitter saturation voltage of 300mV. Its 4-Mini-Flat package, specifically a 4-SOIC (0.173", 4.40mm Width), is designed for surface mounting. Typical rise and fall times are 3µs each. This optoisolator is commonly utilized in power supplies, industrial automation, and telecommunications equipment where reliable signal isolation is critical.
