Quality Control: Learn More
The onsemi FODM121E is a single-channel optoisolator featuring a transistor output. This component provides 3750Vrms isolation, essential for applications requiring robust electrical separation. Designed for surface mounting in a 4-SMD gull wing package, it offers a DC input type with a typical forward voltage (Vf) of 1.3V and a maximum forward current (If) of 50mA. The output transistor can handle up to 80mA and a maximum output voltage of 80V, with a Vce saturation of 400mV. Current transfer ratios range from a minimum of 50% at 5mA to a maximum of 600% at 5mA. The device operates across a temperature range of -40°C to 110°C, with typical rise and fall times of 3µs. This optoisolator is commonly utilized in industrial control, power supplies, and medical equipment to ensure signal integrity and protect sensitive circuitry.
