Quality Control: Learn More
The onsemi HMA121CV is a high-isolation optocoupler featuring a transistor output. Designed for demanding applications, this component provides 3750Vrms of isolation between the input and output stages. It offers a single channel with a 4-SMD, Gull Wing package for efficient surface mounting. The device operates with a DC input and supports a forward current of up to 50 mA. The output transistor can handle up to 80 mA and features a saturation voltage of 400mV maximum. Current transfer ratios range from a minimum of 100% at 5 mA to a maximum of 200% at 5 mA. Typical rise and fall times are 3µs. This optoisolator is suitable for use in industrial automation, telecommunications, and power supply applications where robust electrical isolation is critical. It operates within a temperature range of -40°C to 100°C.
