Quality Control: Learn More
The onsemi HMHAA280R4 is a high-performance optoisolator featuring a transistor output. This single-channel device provides 3750Vrms isolation and is housed in a compact 4-SMD package, specifically a 4-Mini-Flat. It supports both AC and DC input signals, with a typical forward voltage of 1.4V and a maximum forward current of 50mA. The output current capability is also 50mA, with a maximum Vce saturation of 400mV. Current transfer ratios range from a minimum of 50% at 5mA to a maximum of 600% at 5mA, ensuring robust signal transfer. Typical rise and fall times are 3µs. This component is suitable for applications requiring reliable signal isolation in industrial automation, power supplies, and control systems. It is supplied on tape and reel.
