EL3H7 SMD IC Opto couplers Everlight 3H7 SOP4 EL3H7(C)(TA)-G

Product Overview:

A surface-mount, 4-pin small outline phototransistor photocoupler integrated circuit designed for compact, reliable signal isolation and transmission. Fabricated using an infrared emitting diode optically coupled to a phototransistor detector and encapsulated in a specialized green compound, it isolates different circuit potentials and impedances while maintaining a very low profile.

Core Specifications:

Features

• Compact Low-Profile Packaging: Encapsulated in a 4-pin SSOP layout with a slim 2.0 mm thickness, making it ideal for space-constrained circuit layouts.

• High Electrical Isolation: Provides a substantial high isolation voltage threshold reaching up to 3750 Vrms between the input and output circuits.

• High Current Transfer Ratio: Features broad current transfer ratio options ranging from 50 percent up to 600 percent under specified testing biases.

• Halogen and Lead-Free Design: Fully compliant with EU REACH, lead-free, RoHS, and strict green manufacturing halogen standards.

• Comprehensive International Approvals: Officially certified under safety standards including UL, cUL, VDE, SEMKO, NEMKO, DEMKO, FIMKO, and CQC.

Applications

• DC-to-DC Converters: Provides isolated voltage feedback loops to regulate switching power conversion structures safely.

• Programmable Logic Controllers (PLCs): Interfaces low-voltage microprocessor circuits with high-voltage industrial field inputs and outputs.

• Telecommunication Equipment: Isolates phone, data transmission, and network routing hardware from high-voltage line surges.

• Inter-Potential Signal Transmission: Executes noise-free data coupling between separate electronic subsystems possessing completely different voltage potentials or ground references.
