TIL198XG

Overview

The TIL198XG is a dual-channel photodarlington optocoupler manufactured by Isocom Components. It features an infrared LED input paired with NPN silicon Darlington transistor outputs in an 8-pin DIP package. The device provides high isolation voltage of 5300Vrms and supports a wide operating temperature range from -55°C to +100°C. Designed for through-hole mounting, it offers high current transfer ratios suitable for robust signal isolation applications.

Feature Summary

Dual-channel configuration with independent infrared LED inputs and NPN Darlington outputs
High isolation voltage rating of 5300Vrms for reliable circuit separation
Wide operational temperature range supporting extreme environmental conditions
High density 8-pin DIP packaging optimized for standard board layouts

Applications

Industrial control systems requiring galvanic isolation
Solid-state relay driver circuits
Power supply feedback loops
Microcontroller interface isolation

Procurement Notes

Verify the specific suffix XG against official manufacturer documentation to confirm pinout compatibility and lead frame material specifications. Ensure that the procurement channel sources components directly from authorized distributors or verified suppliers to guarantee authenticity. Cross-reference the manufacturing date code with current production status as component availability may vary over time.

Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. The Darlington output structure provides high gain, making it suitable for driving loads directly without additional amplification stages. Consider the thermal management requirements due to the high current transfer ratio and ensure the PCB layout accommodates the 8-pin DIP spacing constraints.

Part Context

This part belongs to the TIL198 series of high-density photodarlington optocouplers. It is designed to replace older discrete isolation solutions by integrating two channels into a single package. The series is characterized by its robust construction and ability to handle significant current loads while maintaining electrical safety standards.
