What is the forward current (If) range through the OC-100 LED? What about current through the OC025?
For the OC-100 family, each LED is rated at 100mA.
For the OC025 (2.5kV opto-coupler), the rated If of 50mA, is for a single LED. VMI recommends that all four LEDs are connected in series so each LED sees the same amount of current.
