Assume a mistaken desire to use a "1458 optocoupler" – instead, we select the . 1458 optocoupler datasheet
CTR=(ICIF)×100%CTR equals open paren the fraction with numerator cap I sub cap C and denominator cap I sub cap F end-fraction close paren cross 100 % It functions similarly to the DC current gain
The Current Transfer Ratio is the most critical parameter when designing with the 1458 optocoupler. It functions similarly to the DC current gain ( hFEh sub cap F cap E end-sub ) of a standard bipolar transistor. If you share with third parties, their policies apply

The Current Transfer Ratio is the ratio of output collector current ( ICcap I sub cap C ) to input forward current ( IFcap I sub cap F ), expressed as a percentage:
Provides a high insulation voltage of 5000 Vrms (or 3750 Vrms for certain packages like the standard 8-pin DIP).
