Product Overview
The XLH11A4-G is documented as a XINGLIGHT LED-category phototransistor optocoupler. The extracted ordering data identifies XLH11A4 as the DIP6 package option, with SMD6 also available under XLH11A4S marking. The DIP6 shipping quantity is 65 pcs per tube, and the marking code is XLH11A4 for both DIP6 and SMD6 variants.
Electrical parameters center on isolated optocoupler signal transfer. The device has 5000 Vrms input-output isolation, a minimum current transfer ratio of 20% at IF=10 mA and VCE=10 V, and typical 3 us rise and fall response times under the specified VCE=10 V, IC=2 mA, RL=100 ohm condition. Input-side limits include 60 mA forward current, 6 V reverse voltage, and 100 mW input power dissipation.
Assembly guidance includes a 260 °C soldering temperature for 10 seconds, a 260 °C reflow peak, and a 260 °C wave soldering peak. The stated operating range is -55 to +100 °C, with storage from -55 to +125 °C.
