Each channel accepts a DC input and drives a phototransistor output with a minimum current transfer ratio of 40% at 10 mA forward current. The 2500Vrms isolation rating provides basic functional separation between input and output circuits — enough for many industrial and consumer applications where reinforced isolation is not mandated. ## Switching speed and drive capability Typical rise and fall times of 3.2 µs and 4.7 µs limit the usable data rate to roughly 100 kHz — fine for GPIO, relay drive, and slow sensor interfaces, but not for high-speed serial buses like SPI or I2C. Each output can sink up to 150 mA continuously with a maximum Vce saturation of 400 mV, making it suitable for driving small relays, LEDs, or logic inputs directly. ## Temperature range and environment fit Rated for -40°C to 100°C operation, the MOCD208R2M covers factory-floor, outdoor telecom, and HVAC control enclosures. ## Lifecycle and sourcing reality onsemi lists the MOCD208R2M as Active with ROHS3 compliance. Available in Tape & Reel (TR) or Cut Tape (CT).","metaTitle":"MOCD208R2M onsemi Dual-Channel Optoisolator, 8-SOIC","metaDescription":"onsemi MOCD208R2M dual-channel transistor-output optocoupler. 2500Vrms isolation, 40-125% CTR at 10mA, -40°C to 100°C.
