XL4N29-G Photo Darlington Optocoupler

Specifications

Product Overview

The XL4N29-G is a XINGLIGHT photo Darlington optocoupler in the XL4N29, XL4N33 series. Its datasheet identifies DIP6 and SMD6 mechanical case options, with a UL 94V-0 molding compound flammability rating and matte tin-plated leads with solderability per MIL-STD-202, Method 208.

Electrical ratings include 5000 Vrms isolation voltage, -55 to +100 °C operating temperature, and -55 to +125 °C storage temperature. For the XL4N29 condition of IF=10 mA and VCE=10 V, the datasheet gives a minimum current transfer ratio of 100%. Input-side parameters include 60 mA maximum forward current, 6 V maximum reverse voltage, and a forward voltage of typically 1.2 V and maximum 1.5 V at IF=10 mA.

Output-side limits include 100 mA maximum collector current, 30 V maximum collector-emitter voltage, and 150 mW maximum collector power dissipation. Assembly guidance includes 260 °C reflow peak temperature, 260 °C wave soldering peak temperature, and 360 °C +5 °C hand soldering iron temperature within 3 seconds for rework or sample testing.

Procurement Notes

When requesting a quote for XL4N29-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.
