Quality Control: Learn More
The onsemi CNY1743S is a single-channel optoisolator featuring a transistor output with a base connection. This device provides 5300Vrms of isolation and is housed in a 6-SMD gull-wing package suitable for surface mounting. It is designed for DC input and offers a maximum forward current of 100 mA with a typical forward voltage of 1.35V. The output transistor can handle up to 70V and delivers 50mA. Current transfer ratios range from a minimum of 160% to a maximum of 320% at 10mA forward current. Typical rise and fall times are 1µs and 2µs respectively, with turn-on and turn-off times of 2µs and 3µs. The CNY1743S operates within a temperature range of -55°C to 100°C and is supplied in tubes. This component finds application in industrial automation, power supplies, and telecommunications equipment.
