TIL197

Overview

The TIL197 is a single-channel Darlington output optocoupler manufactured by Isocom Components 2004 LTD. It features a 4-pin DIP plastic package with through-hole mounting. The device provides 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward current of 50mA, a typical rise time of 100μs, and a typical fall time of 100μs. The minimum current transfer ratio is 500%, with a maximum of 7500%. It is UL recognized and compliant with RoHS standards.

Feature Summary

Darlington transistor output configuration for high gain
AC input capability with integrated rectification
High isolation voltage rating for safety applications

Applications

Solid-state relay driver circuits
Mains voltage switching interfaces
Industrial control system isolation

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD on official datasheets. Confirm the package type is DIP-4 and the output stage is Darlington. Ensure compliance requirements such as UL recognition and RoHS status match project specifications before procurement.

Selection Notes

Select this component when AC line sensing or high-gain DC coupling is required. The Darlington output offers superior sensitivity compared to standard phototransistor variants. Verify that the 100μs switching speed meets the application timing constraints. Ensure the 5300Vrms isolation rating satisfies the circuit's safety clearance requirements.

Part Context

The TIL197 belongs to the TIL197 series of optocouplers from Isocom Components 2004 LTD. It is designed for general-purpose isolation where high current transfer ratios are beneficial. The device utilizes infrared technology to transmit signals across the isolation barrier.
