Additional Details

The ISP321-2SMT-R optocoupler consists of an infrared emitting diode (IRED) and a phototransistor. When current flows through the IRED, it emits infrared light, which activates the phototransistor. This provides electrical isolation between the input (IRED) and output (phototransistor) circuits. Key specifications include the isolation voltage (typically several kilovolts), current transfer ratio (CTR), input forward current, and output collector-emitter voltage. The CTR indicates the ratio of output current to input current. The surface mount package allows for automated assembly using standard SMT equipment. Consult the Isocom Components 2004 LTD datasheet for detailed electrical characteristics, package dimensions, and recommended operating conditions. The tape and reel packaging facilitates efficient pick-and-place assembly processes.
