Quick Sourcing Note

XL4N33S-G from XINGLIGHT is an LED-category Photo Darlington optocoupler supplied in an SMD6 package. The SMD6 version is specified for 1000 pcs per tape-and-reel and uses marking code XL4NXX. Key limits include 60 mA forward current, 1 A forward peak current, 6 V reverse voltage, 100 mA collector current, and 5000 Vrms isolation voltage. Electrical data includes 1.3 V typical forward voltage at IF=10 mA, minimum 500% current transfer ratio for 4N32/4N33 conditions, and maximum 5 us turn-on time. Application fit centers on isolated input-output signal transfer, transistor-output interfaces, and circuits requiring defined isolation resistance and capacitance.
