Quality Control: Learn More
The onsemi HMHA281R1 is a single-channel optoisolator featuring a transistor output. This component provides 3750Vrms of isolation and is housed in a 4-SMD package. It supports a DC input type with a maximum forward current of 50mA and an output current capability of 50mA per channel. The current transfer ratio ranges from a minimum of 50% at 5mA input to a maximum of 600% at 5mA input. With a forward voltage of 1.3V typical, the device exhibits a Vce saturation of 400mV maximum. Typical rise and fall times are 3µs. This optoisolator is suitable for surface mounting and operates across a temperature range of -55°C to 100°C. The HMHA281R1 is commonly utilized in industrial automation, power supplies, and telecommunications equipment.
