Product Overview
XL6N139S-G is a XINGLIGHT photo Darlington optocoupler in the LED category. The ordering information identifies the S suffix as the SMD8 package type, with 1000 pieces supplied on tape and reel. The marking code is XL6N13X, where X denotes product series 8 or 9.
The input side is rated for 20 mA average forward current, 40 mA peak forward current under 50% duty cycle with 1 ms pulse width, and 1.0 A peak transient input current for pulses below 1 us at 300 pps. Recommended operating input drive is 0.5 to 12.0 mA, and the recommended off input voltage is 0 to 0.8 V.
On the output side, the 6N139 conditions specify an 18 V maximum supply and output voltage, 60 mA output current, and low-level output voltages from 0.05 V typical to 0.4 V maximum depending on IF, IO, and VCC. Isolation is rated at 5000 Vrms for 1 minute at TA=25 °C and RH<50%.
Assembly data includes a 150 to 200 °C reflow preheat range for 60 to 120 s, 217 °C liquidus temperature, and 260 °C peak reflow temperature recommended no more than three times.

Procurement Notes
When requesting a quote for XL6N139S-G, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
