Quality Control: Learn More
The onsemi HMHAA280R3 is a single-channel optoisolator featuring a transistor output. This device provides 3750Vrms of isolation, making it suitable for applications requiring robust electrical separation. It supports both AC and DC input signals and delivers an output current of up to 50mA. The current transfer ratio (CTR) ranges from a minimum of 50% at 5mA to a maximum of 600% at 5mA. Rise and fall times are typically 3µs. The HMHAA280R3 is housed in a 4-SMD package (4-Mini-Flat) for surface mounting, with a Vce saturation of 400mV maximum and a forward voltage of 1.4V typical maximum. Operating temperature ranges from -55°C to 100°C. This component is commonly utilized in industrial automation, power supply control, and telecommunications systems.
