Quality Control: Learn More
The onsemi HMA121A is a single-channel optoisolator featuring a transistor output. This device provides 3750Vrms of isolation and is housed in a 4-SMD, Gull Wing package suitable for surface mounting. It operates with a DC input type and offers an output current of 80mA. The current transfer ratio (CTR) ranges from a minimum of 100% at 5mA input to a maximum of 300% at 5mA input. The forward voltage (Vf) is typically 1.3V, with a maximum forward current (If) of 50mA. The output transistor exhibits a saturation voltage (Vce Sat) of 400mV and can handle up to 80V. Rise and fall times are approximately 3µs. This component is utilized in various industrial applications including power supplies, motor control, and telecommunications equipment. The operating temperature range is -40°C to 100°C.
