TIL197ASMT&R

Overview

The TIL197ASMT&R is a single-channel optocoupler manufactured by Isocom Components 2004 LTD, featuring a Darlington output configuration. It is housed in a surface-mount PDIP package with four pins. The device provides an isolation voltage of 5.3 kVrms and supports a collector-emitter voltage (V(br)ceo) of 35V. It offers a current transfer ratio of 1000% and can handle up to 50 mA of output current.

Feature Summary

Utilizes a Darlington phototransistor output structure for high gain amplification
Provides robust electrical isolation between input and output circuits
Designed for surface-mount assembly using a compact four-pin package

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops
Solid-state relay driver circuits

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD against official component documentation. Confirm the specific suffix 'SMT&R' corresponds to the required surface-mount packaging and tape-and-reel delivery format. Ensure the part number matches the single-channel Darlington specification rather than other variants within the same series.

Selection Notes

Select this component when high current transfer efficiency is required due to the Darlington output stage. Consider the 5.3 kVrms isolation rating for applications demanding significant voltage separation. Evaluate the surface-mount footprint compatibility with the target PCB design. Verify that the 35V collector-emitter voltage meets the load requirements of the driven circuit.

Part Context

This component belongs to the family of optocouplers produced by Isocom Components 2004 LTD. It shares the general isolation architecture with other models like the TIL199ASMT&R but differs in channel count and specific electrical characteristics. The TIL197ASMT&R is distinct from through-hole DIP versions and different output types such as standard phototransistors found in CNY17 series parts.
