Forward current led
WebOct 6, 2024 · Max Forward voltage of the LED is 1.4V, with 1k resistor and 3V3 GPIO that gives a minimum 1.9mA LED current. Check "current transfer ratio" in datasheet: Minimum is 300% (ie, 3) and this means with 1.9mA LED current, the phototransistor will pass at least 5.7mA. At this current it will not be fully saturated, so 1K value for R8 is too low. WebThe Peak Forward Current, I F (peak), specification of an LED serves to tell you the maximum current that an LED can be fed without being damaged or destroyed. An LED …
