The current transfer ratio is specified at 160% minimum to 256% maximum at a forward current of 10mA, giving a defined gain band for the output transistor that simplifies worst-case design for logic-level interfacing or driving a downstream load up to 50mA. ## Switching speed and output drive Rise and fall times are both 2µs typical, with turn-on time of 3µs and turn-off time of 2.3µs. That puts this part in the general-purpose optocoupler class — fine for 10-100 kHz switching signals, serial data isolation at lower baud rates, or DC level sensing. The output transistor is rated for 30V maximum and 50mA continuous per channel, with a Vce saturation of 400mV maximum. For a 5V logic rail, that saturation voltage leaves about 4.6V of swing, enough to drive a CMOS input directly. The 60mA absolute maximum forward current on the input side gives headroom for driving the LED at 10-20mA without stressing the part. ## Temperature range and package rework Operating temperature spans -55°C to 100°C, which covers industrial environments and most outdoor telecom cabinets. The 6-SMD gull-wing package is straightforward to hand-solder or rework — the leads are visible, easy to inspect, and the part is small enough that a hot-air station at 300°C with a fine nozzle lifts it cleanly without cooking the board. No exposed thermal pad, so no via-stitch requirement. The gull-wing leads also give a bit of compliance for thermal cycling on FR4.","metaTitle":"MOC8104-X019T Optocoupler, 5300Vrms, 160-256% CTR, 6-SMD","metaDescription":"MOC8104-X019T optocoupler: 5300Vrms isolation, DC input, transistor output, 160-256% CTR at 10mA, -55°C to 100°C, 6-SMD gull wing.
