How to Determine Optocoupler Operation Saturation or Linear

There are several ways on how to determine Optocoupler operation. The old school method is to build an actual circuit and measure the collector-emitter voltage. If the reading is low enough (equal to the saturation voltage of the device) or ideally zero, the Optocoupler is operating at saturation. If the reading is higher than the specified saturation voltage but lower than the collector supply level, the device is operating at linear mode. Another method on how to determine Optocoupler operation is thro
