Categories: Transistor, Photovoltaic Output Optoisolators
Quality Control: Learn More
The onsemi HMHA2801AR3 is a single-channel optoisolator featuring a transistor output. This device provides 3750Vrms of isolation and is housed in a 4-Mini-Flat (4-SOIC) package suitable for surface mounting. It operates with a DC input and supports a forward current of up to 50mA. The current transfer ratio (CTR) ranges from a minimum of 80% at 5mA to a maximum of 160% at 5mA. The output current capability is 50mA, with a Vce saturation of 300mV (Max). Typical rise and fall times are 3µs each. This component is designed for applications requiring robust galvanic isolation, such as in power supplies, industrial automation, and medical equipment. The operating temperature range is -55°C to 100°C.
