Optocoupler

I assume you know how to estimate driver impedance Vol/Iol=Zol 50 Ω typ +/-50%. Due to Early leakage effects in any transistor, a base shunt R is preferred, instead of your diode shunt resistor.. You must examine the source impedance and current then CTR of the whole device with common-mode RFI interference.
