TIL197SMT&R

Overview

The TIL197SMT&R is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output and provides an isolation voltage of 5300Vrms. The device operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward current of 50 mA, a typical current transfer ratio of 500%, and a maximum dark current of 100 nA. The component is housed in a surface-mount DIP-4 package.

Feature Summary

• Utilizes a Darlington transistor output configuration for high gain applications
• Provides robust electrical isolation with a 5300Vrms rating
• Operates reliably across an extended industrial temperature range

Applications

• Industrial control systems requiring high-gain signal isolation
• Power supply feedback loops
• Microprocessor interface circuits

Procurement Notes

Verify the specific suffix 'SMT&R' to confirm the surface-mount tape-and-reel packaging format. Ensure compatibility with existing PCB footprints designed for the 4-pin SOP/DIP variant. Confirm that the Darlington output characteristics align with the required load driving capabilities for the target application circuit design.

Selection Notes

Select this component when high current transfer ratio is necessary to drive loads directly without additional amplification stages. The wide operating temperature range supports deployment in harsh environments. Verify that the 5300Vrms isolation rating meets the safety requirements of the system architecture being designed.

Part Context

This part belongs to the TIL197 series of optocouplers. It is functionally similar to other Darlington output isolators but is distinguished by its specific surface-mount packaging and manufacturer specifications. It serves as a compact solution for galvanic isolation in space-constrained electronic designs.
