| Optocoupler parameters |
* Answer
| Forward voltage drop VF: The voltage drop generated between the positive and negative electrodes when the forward current through the diode is a specified value.Forward current IF: The current flowing through the diode when a certain forward voltage is applied across the tube to be tested.Reverse current IR: The current flowing through the diode when a specified reverse operating voltage VR is applied across the tube under test.Output saturation voltage drop VCE(sat): When the LED operating current IF and the collector current IC are specified, and the IC/IF ≤ CTRmin is maintained (CTRmin is specified in the test tube technical conditions) between the collector and the emitterThe voltage drop.Output saturation voltage drop VCE(sat): When the LED operating current IF and the collector current IC are specified, and the IC/IF ≤ CTRmin is maintained (CTRmin is specified in the test tube technical conditions) between the collector and the emitterThe voltage drop.Output saturation voltage drop VCE(sat): When the LED operating current IF and the collector current IC are specified, and the IC/IF ≤ CTRmin is maintained (CTRmin is specified in the test tube technical conditions) between the collector and the emitterThe voltage drop.Insulation isolation voltage VIO: insulation withstand voltage between the optocoupler input and output. |
