FODM1009R2

FODM1009R2 Description

The FODM1009R2 from onsemi is a high-performance, single-channel phototransistor optoisolator designed for reliable signal isolation in demanding applications. It features a 5,000Vrms isolation voltage, making it suitable for high-voltage environments while ensuring safety and noise immunity. With a DC input type and transistor output, this optoisolator delivers a current transfer ratio (CTR) of 200% to 400% at 5mA, ensuring efficient signal transmission. The device operates with a forward voltage (Vf) of 1.4V (Typ) and supports an output current of 50mA per channel, making it ideal for low-power control circuits. Packaged in a surface-mount LSOP4 and available in Tape & Reel (TR), it is optimized for automated assembly.
