The CNY17F4SM is a 6-pin surface-mount phototransistor optocoupler featuring a gallium arsenide infrared LED coupled with an NPN phototransistor. It is designed for signal isolation in power supply regulators, microprocessor interfaces, and industrial control systems. The device has a minimum collector-emitter breakdown voltage of 70 V, a maximum continuous collector current of 50 mA, and a current transfer ratio between 160% and 320% at 10 mA forward current and 5 V collector-emitter voltage. It meets UL1577 (4,170 VAC RMS for 1 minute) and DIN EN/IEC60747-5-5 (850 Vpeak working insulation voltage) safety standards. The package is a 6-pin SMD with lead bend, dimensions conforming to PDIP6 case style 8.51 x 6.35 mm with 2.54 mm pitch. The device operates from -40°C to +100°C ambient temperature and complies with RoHS standards.
