Product Overview
The XL4N29S-G is a XINGLIGHT photo Darlington optocoupler in the LED category. The device uses an SMD6 package and is specified for 5000 Vrms input-output isolation, including an AC 1 minute isolation rating with pins 1/2/3 shorted and pins 4/5/6 shorted under 40 to 60% RH conditions.
Input-side ratings include 60 mA forward current, 1 A forward peak current for pulse width <=1 us at 0.001 duty ratio, 6 V reverse voltage, and 100 mW input power dissipation. Output-side ratings include 150 mW collector power dissipation, 100 mA collector current, 50 V collector-base voltage, 30 V collector-emitter voltage, and 5 V emitter-collector voltage.
Assembly data includes a 260 °C soldering temperature for 10 seconds, a reflow preheat range of 150 to 200 °C for 60 to 120 seconds, 260 °C reflow peak temperature, and 60 to 150 seconds above 217 °C liquidus. These facts support use in isolated signal coupling and board-level SMD assemblies requiring photo Darlington optocoupler behavior.
