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.
