Product Overview

The XL814(X)S-G is a XINGLIGHT phototransistor optocoupler in the LED category. The extracted package information covers DIP4, DIP4-M, and SMD4 outlines, with package outline dimensions referenced in millimeters but without numeric dimensions in the extracted text. Shipping configurations include 100 pcs/tube for XL814X DIP4, 100 pcs/tube for XL814MX DIP4-M, and 2000 pcs/tape & reel for XL814SX SMD4.

Electrical isolation and transfer behavior are defined by a 5000 Vrms input-to-output isolation voltage under 40-60% RH for 1 minute and a 20-300% current transfer ratio at IF=±1 mA and VCE=5 V. CTR rank options include A at 50-150%, B at 100-300%, and no-mark at 20-300% under the same test condition.

Ratings include -55 to +100 °C operating temperature in the maximum ratings table, -55 to +110 °C in the feature list, and -55 to +125 °C storage temperature.

Procurement Notes

When requesting a quote for XL814(X)S-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.
