Product Overview
XL452S-G is a XINGLIGHT photo Darlington optocoupler supplied in an SOP4 case. The extracted datasheet facts specify a minimum current transfer ratio of 1000% at IF=1 mA and VCE=2 V, with 3750 Vrms input-to-output isolation. These parameters support use where an optical input-to-output isolation barrier and high CTR are required.
The input side is rated for 60 mA forward current, 1 A peak forward current under the stated pulse condition, 6 V reverse voltage, and 100 mW input power dissipation. Output-side limits include 150 mA collector current, 350 V collector-emitter voltage, and 150 mW collector power dissipation.
Assembly and handling facts include matte tin-plated leads, copper leadframe, UL 94V-0 molding compound flammability, and solderability per MIL-STD-202 Method 208. Reflow, wave soldering, and hand soldering profiles are defined, with 260 °C peak values for reflow and wave soldering.

Procurement Notes
When requesting a quote for XL452S-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 optocoupler and isolation sourcing, isolation voltage, CTR or output type, package, creepage distance, temperature grade, agency approvals and soldering conditions should be verified before approval.
