It accepts DC input and provides a transistor output with a current transfer ratio (CTR) guaranteed between 100% and 200% at a forward current of 10mA. The 100% to 200% CTR range at 10mA forward current defines the gain margin for logic-level coupling. A CTR below 100% may not saturate the output transistor sufficiently for TTL/CMOS inputs, while a CTR above 200% can cause slow turn-off due to excess base charge. Typical rise and fall times are 2µs each, with turn-on at 3µs and turn-off at 2.3µs — adequate for 10-100 kbps isolated data links or low-frequency PWM feedback. The 400mV maximum Vce saturation at the rated output current ensures low voltage drop when the transistor is fully on. ## Package and mounting — 4-SMD Gull Wing The SFH6156-3X001T is supplied in a 4-SMD Gull Wing package, a standard surface-mount optocoupler footprint compatible with many Vishay, Broadcom, and Toshiba alternatives. The surface-mount Gull Wing leads are suitable for reflow soldering; observe standard MSL handling per the device's moisture sensitivity level. ## Lifecycle and compliance — active, ROHS3 It is ROHS3 compliant, covering the full RoHS exemption list.","metaTitle":"SFH6156-3X001T Optocoupler, 5300Vrms, 100-200% CTR, 4-SMD","metaDescription":"SFH6156-3X001T Vishay optocoupler: 5300Vrms isolation, 100-200% CTR at 10mA, transistor output, -55°C to 100°C, 4-SMD Gull Wing.
