ONSEMI FOD817BS High-Temperature Optocoupler

The FOD817 Series consists of high-temperature 4-pin optocouplers with gallium arsenide infrared emitting diodes driving silicon phototransistors in compact dual in-line packages. These optocouplers feature high input-output isolation voltages of 5000Vrms, making them ideal for digital logic interfaces, power supply regulation, and microprocessor inputs. Their broad current transfer ratios (50-600%) and high collector-emitter voltage (70V) ensure reliable performance in various industrial and communication applications, with excellent thermal characteristics and UID approvals supporting Pb-free reflow soldering.
