TIL197SM

Overview

The TIL197SM is a single-channel optocoupler from the TIL197 series manufactured by Isocom Components. It features an AC input and a Darlington transistor output, housed in a 4-pin DIP package. The device provides high isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 100μs, and a typical fall time of 100μs. It operates within a temperature range of -55°C to 100°C and carries UL recognition certification.

Feature Summary

Provides galvanic isolation for signal transmission between separate electrical circuits
Utilizes a Darlington output configuration for high current transfer capability
Designed for through-hole mounting in standard DIP-4 packages

Applications

General purpose electrical isolation applications
AC signal interfacing and detection
Industrial control systems requiring high isolation voltage

Procurement Notes

Verify the specific suffix SM indicates surface mount or specific packaging variant compared to the standard TIL197, as datasheets may list both DIP and SMD variants under similar numbering. Confirm lead times and availability directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS and REACH regulations if required for your specific manufacturing process.

Selection Notes

Select this component when high current transfer ratio is needed due to the Darlington output stage. It is suitable for applications requiring AC input compatibility without additional rectification circuitry on the input side. Consider the 100μs switching speed limitations for high-frequency applications; slower speeds are acceptable for low-frequency signaling or power supply feedback loops.

Part Context

The TIL197SM belongs to the TIL197 family of optocouplers produced by Isocom Components. This series is characterized by its robust isolation capabilities and compatibility with standard industrial interfaces. The SM suffix typically denotes a specific package style or tape-and-reel option within the manufacturer's catalog, distinguishing it from the standard tube-packaged DIP version.
