Product Overview

The TLP290-4(GB-TP,E(T) is a high-performance optocoupler with four independent channels, designed using GaAs infrared LEDs and phototransistors for excellent electrical isolation and signal transmission. Its compact SO16 surface-mount package enables high-density PCB layouts, while the wide operating temperature range (-55℃~110℃) makes it suitable for harsh environments in industrial control and power systems, effectively isolating input/output signals and suppressing noise interference.

Key Features

• Quad Independent Channels: Integrates four separate optocoupler channels in a single package, supporting multi-channel signal isolation to save PCB space and simplify design.
• High Electrical Isolation: Provides a 2500Vrms minimum isolation voltage to block high-voltage interference and surges, meeting industrial safety standards.
• Wide Temperature Operation: Supports an operating temperature range of -55℃~110℃, eliminating the need for additional temperature control in extreme conditions.
• High Current Transfer Ratio: Achieves a 100% minimum CTR (GB rank), ensuring consistent and reliable signal transmission.
• Multiple Safety Certifications: Certified by UL1577, cUL, VDE, and compliant with EN 60747-5-5, ensuring safety and regulatory compliance globally.

Technical Specifications

Typical Applications

• Industrial Automation: Isolates multiple control signals and sensor inputs in PLCs and industrial robots, preventing ground loop interference and enhancing system noise immunity.
• Switching Power Supplies: Used for multi-channel signal isolation in power feedback loops, achieving input-output electrical isolation to optimize efficiency and protect downstream circuits.
• Data Communication Systems: Isolates transmit/receive signals in serial ports and CAN buses, reducing EMI in long-line transmission to ensure data accuracy.
• Measurement Equipment: Suitable for multi-channel signal acquisition and isolation in measuring devices, protecting weak signals from noise and improving measurement precision.
