Product Overview
XLM4401-G is a XINGLIGHT photo relay listed in the LED category and supplied in an SOP4 package. The relay contact form is normally opened SPST, with output ratings of 60 V peak AC load voltage, 0.5 A peak AC continuous load current, and 1.5 A peak load current at Ta=25°C unless otherwise specified.
Input-side limits include 50 mA forward current, 1 A peak forward current under pulse conditions, 5 V reverse voltage, and 75 mW input power dissipation. The device specifies 3750 Vrms isolation voltage for 1 minute at 40 to 60% RH, with initial I/O isolation resistance of at least 1000 Mohm at 500 VDC.
Electrical characteristics at Ta=25°C include 0.4 mA typical LED turn-on current, 0.3 mA typical LED turn-off current, 1.3 V typical LED dropout voltage, 0.9 ohm typical on resistance, and 1000 nA maximum off-state leakage current. Assembly data includes matte tin-plated leads, UL 94V-0 molding compound, and a reflow profile with 260°C peak temperature.

Procurement Notes
When requesting a quote for XLM4401-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.
