Product Overview

TLP293-4 is a 4-channel transistor output optocoupler available in DIP-16/SOP-16 packages, designed for high-density signal isolation. Each channel offers 3750Vrms isolation voltage and supports -55°C to +125°C wide-temperature operation, suitable for industrial control, power management, and smart home applications. The device balances low input current (5mA typical) with high CTR (100%-600%), certified by UL, VDE, and CQC for safety and reliability.

Key Features

• 4-Channel Integrated Design: Single-chip integration of 4 independent isolated channels saves over 50% PCB space, enhancing system density.
• High-Grade Electrical Isolation: 3750Vrms isolation voltage per channel protects against EMI, ensuring safe multi-channel signal transmission.
• Wide-Temperature Adaptability: -55°C to +125°C operating range supports harsh industrial and automotive high-temperature environments.
• Low-Power High Efficiency: 5mA typical input current combined with 100%-600% high CTR reduces energy consumption while maintaining signal accuracy.
• Multiple Safety Certifications: Certified by UL 1577, VDE 0884-10, CQC, and compliant with RoHS, meeting global market access standards.
