It provides 2500 Vrms of galvanic isolation between input and output, which is the baseline for industrial signal isolation, PLC digital inputs, and motor-drive feedback interfaces. What sets this part apart is its high current transfer ratio — 500% minimum at only 1 mA forward current. That means the input LED can be driven by a 3.3 V or 5 V logic output with a simple series resistor, and the output side still delivers enough base drive to saturate the Darlington at its full 150 mA output current rating. ## Output drive and switching speed — what the numbers mean With a maximum Vce(sat) of 1 V at 150 mA, the MOC223R2M can directly drive a small relay coil, a solenoid, or an indicator LED without an external transistor. The 150 mA continuous output current is enough for most 24 V industrial loads, but the Darlington's turn-on time (10 µs typ) and turn-off time (125 µs typ) mean this is not a high-speed isolator — it suits DC-level or low-frequency switching, not PWM above a few kilohertz. The rise and fall times (8 µs and 110 µs typical) are consistent with a Darlington output stage, which trades speed for gain. If you need faster switching, look at a phototransistor opto (like the MOC8101) or a digital isolator, but the MOC223R2M wins on input sensitivity. ## Package, temperature grade, and production status Housed in an 8-SOIC package (3.90 mm width, 0.154-inch body), the MOC223R2M is a surface-mount part that saves board area compared to the DIP-8 version. The -40°C to 100°C operating temperature range covers industrial and outdoor telecom enclosures without derating.
