Additional Details:

The PS9313L-E3 typically comes in a SO (Small Outline) package. Key electrical specifications include the LED forward current (IF), the collector-emitter voltage (VCEO) of the output transistor, and the isolation voltage (BV). Switching characteristics are defined by the turn-on time (ton) and turn-off time (toff). The "E3" likely refers to Pb-free (RoHS compliant) packaging. It is crucial to refer to the manufacturer's datasheet for specific values and recommended operating conditions. This part offers a good balance of speed, isolation, and low power consumption.
