Founded: 1983 · HQ: New Taipei City, Taiwan
Everlight Electronics Co., Ltd. is one of the world's largest optoelectronic component manufacturers, founded in 1983 and headquartered in New Taipei City, Taiwan, listed on the Taiwan Stock Exchange (ticker 2395). Everlight's portfolio spans LEDs (it was for years the world's largest LED packaging house), infrared components, and photocouplers/photointerrupters used in power supplies, industrial I/O, appliance isolation and automotive signals. In the optocoupler catalog the EL357N is the SOP-4 gull-wing surface-mount transistor photocoupler — the SMD sibling of the EL817/PC817 industry-standard family — combining an infrared LED with a phototransistor at 80 V collector-emitter rating and CTR grades selected at order time. It is the workhorse isolation part for SMPS feedback loops, MCU I/O isolation and signal coupling in space-constrained SMT assemblies, cross-referencing directly to Sharp's PC357N series. Our Shenzhen warehouse stocks the EL357N from Everlight authorized distribution, with CTR-bin sample verification on every lot to reject remarked and out-of-bin photocouplers.

Sourcing from Everlight Electronics – FAQ
Is the EL357N counterfeit-prone?
Photocouplers are a known remarking target — frauds include out-of-bin parts relabeled with higher CTR grades, aged stock with degraded LED output, and pulls from e-waste boards. The failure mode is subtle: CTR below grade means feedback loops run out of regulation margin years early. We sample-verify CTR against the marked bin (measuring IC/IF at spec conditions), check LED forward voltage consistency, and inspect package/laser marking under magnification. All EL357N ships from Everlight authorized distribution in original tape-and-reel with lot codes.
What does the EL357N cross-reference to?
The EL357N (Everlight, SOP-4 gull-wing) is functionally and footprint compatible with Sharp's PC357N series, and is the SMT sibling of the EL817/PC817/LTV-817 DIP-4 family — same internal architecture (IR LED + phototransistor, 80 V CEO, 5000 Vrms-class isolation), different package. If your layout is DIP, use EL817; if it is SMT, EL357N. Specify the CTR grade on your RFQ — Everlight bins grades (A/B/C/D etc.) let you match feedback-loop gain requirements exactly.
Is Everlight a legitimate manufacturer?
Yes — Everlight Electronics was founded in 1983, is listed on the Taiwan Stock Exchange (ticker 2395), and has been among the world's top LED and optoelectronic component makers for decades, with fabs in Taiwan and Asia and supply into automotive, consumer and industrial OEMs worldwide. EL-series photocouplers and LEDs are original Everlight products; we source exclusively through Everlight authorized distribution and provide C-of-C with lot traceability.
What is the lead time for EL357N?
Everlight authorized channel quotes 6-12 weeks for optocouplers. Our Shenzhen warehouse holds EL357N stock across the common CTR grades for 1-2 day shipment on quantities under 20,000 pcs, and we can cross-quote Sharp PC357N or Lite-On equivalents on the same RFQ for landed-cost and availability comparison.
