TIL194G

Overview

The TIL194G is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a transistor output and operates with AC input signals. The device provides an isolation voltage of 5300Vrms across one channel. It utilizes a 4-pin DIP package for through-hole mounting. Key electrical parameters include a maximum forward current of 50 mA, a typical rise time of 100 µs, and a typical fall time of 100 µs. The unit supports a wide operating temperature range from -55°C to 100°C.

Feature Summary

• Supports direct AC input signal processing without external rectification
• Provides high-voltage electrical isolation between input and output circuits
• Features a standard 4-pin dual in-line package for through-hole integration

Applications

• AC line voltage monitoring systems
• Solid-state relay driver circuits
• Industrial control interface isolation

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout configuration and packaging type. Ensure that the selected variant matches the required isolation voltage rating and thermal performance specifications for the intended application environment. Cross-reference part numbers with authorized distributors to confirm authenticity and availability status.

Selection Notes

Select this component when AC input detection is required within an isolated system. Consider the 100 µs switching speed limitations compared to faster logic-level optocouplers. Evaluate the 5300Vrms isolation barrier against system safety requirements. Confirm that the through-hole DIP footprint aligns with the target PCB layout constraints.

Part Context

The TIL194G belongs to the TIL197 series of optocouplers produced by Isocom Components. This family specializes in devices capable of handling AC inputs directly. The component serves as a bridge between low-voltage control logic and higher-voltage AC power stages, ensuring galvanic separation.
