OPTOISO 3.75KV TRANSISTOR 4SMD

Manufacturer: onsemi

Categories: Transistor, Photovoltaic Output Optoisolators

Quality Control: Learn More

The onsemi FODM121CR1 is a single-channel optoisolator featuring a transistor output. This component provides 3750Vrms of isolation and is housed in a 4-SMD, Gull Wing package suitable for surface mounting. It operates with a DC input and supports a maximum forward current of 50 mA, delivering an output current of up to 80 mA per channel. The current transfer ratio (CTR) ranges from a minimum of 100% at 5 mA to a maximum of 200% at 5 mA. With a typical forward voltage of 1.3V, the device exhibits a Vce saturation of 400mV (Max) and an output voltage capability of 80V (Max). The typical rise and fall times are 3µs. This optoisolator is designed for operation within an ambient temperature range of -40°C to 110°C and is supplied on tape and reel. Applications for this device are found in industrial automation, power supplies, and telecommunications equipment.
