Product Overview

The TLP185(GB-TPL,SE) is a cost-effective general-purpose optocoupler designed for electrical isolation and signal transmission. With a 2500Vrms isolation voltage, 1μs typical propagation delay, and a wide operating temperature range of -55℃ to +110℃, it ensures reliable input-output isolation in industrial, consumer electronics, and power systems, effectively suppressing noise interference and safeguarding circuit stability.

Key Features

• Stable Electrical Isolation: Provides 2500Vrms isolation voltage to block grid noise and surge voltage, protecting downstream circuits from high-voltage impacts.
• Low-Delay Signal Transmission: Features a typical propagation delay of 1μs and a 100kbps data rate, meeting real-time transmission needs for medium-speed signals.
• Wide Temperature Operation: Supports an operating temperature range of -55℃ to +110℃, eliminating the need for additional temperature control in harsh environments.
• Low Power & Compact Package: Available in DIP-4 (through-hole) or SOP-4 (surface-mount) packages, with a typical input current of only 10mA to save energy and PCB space.
• Multiple Safety Certifications: Certified by UL1577, VDE, TÜV, and other international standards, ensuring industrial-grade reliability for long-term use.
