Categories: Transistor, Photovoltaic Output Optoisolators
Quality Control: Learn More
The onsemi HMHA281R3V is a single-channel optoisolator featuring a transistor output. This component provides 3750Vrms isolation and is housed in a 4-SMD (4-Mini-Flat) package suitable for surface mounting. It operates with a DC input and offers a maximum output current of 50mA with a typical forward voltage of 1.3V. The current transfer ratio ranges from a minimum of 50% at 5mA to a maximum of 600% at 5mA. Key performance characteristics include a Vce(sat) of 400mV (max) and rise/fall times of 3µs. The HMHA281R3V is designed for applications requiring robust electrical isolation, such as in industrial control systems, power supplies, and telecommunications equipment. It is supplied on tape and reel.
