Product Overview
The XINGLIGHT XL452 is a photo Darlington optocoupler in the LED category, using an SOP4 case and XL452 marking code. Its input-output isolation rating is 3750 Vrms, specified both between input and output and under 40 to 60% RH AC test conditions for 1 minute.
Electrical characteristics include a minimum current transfer ratio of 1000% at IF=1 mA and VCE=2 V, a typical 1.2 V and maximum 1.4 V forward voltage at IF=10 mA, and a maximum input reverse current of 10 μA at VR=4 V. Output ratings include 150 mA collector current, 350 V collector-emitter voltage, and 150 mW collector power dissipation.
The SOP4 package uses matte tin-plated leads with solderability per MIL-STD-202, Method 208, and UL 94V-0 molding compound flammability. Assembly data covers reflow, wave, and hand soldering profiles, including a 260 °C reflow peak temperature and no more than three recommended reflow cycles.

Procurement Notes
When requesting a quote for XL452, 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.
