It is ideally suited for fastswitching driving of power IGBT and MOSFET used in motorcontrol inverter applications, and highperformance power systems. The FOD8 series utilizes stretched body package to achieve 8 mm creepage and clearance distances (FOD8T), and optimized IC design to achieve reliably highinsulation voltage and highnoise immunity. The FOD8 series consists of an Aluminum Gallium Arsenide (AlGaAs) LightEmitting Diode (LED) optically coupled to an integrated circuit with a highspeed driver for pushpull MOSFET output stage. The device is housed in a stretched body, pin, small outline, plastic package. Functional Schematic ANODE CATHODE Figure. Schematic V SS Figure. Package Outline FOD8, FOD8T Rev..0
