TIL197AX

Overview

The TIL197AX is a single-channel Darlington output optocoupler manufactured by Isocom Components. It features a plastic DIP-4 package with through-hole mounting. Key electrical parameters include a maximum isolation voltage of 5300Vrms, a typical rise time of 100μs, and a typical fall time of 100μs. The device supports a maximum forward current of 50mA and has a maximum forward voltage of 1.4V. Operating temperatures range from -55°C to 100°C.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits using a Darlington phototransistor configuration.

Applications

AC mains detection circuits
Solid-state relay driver interfaces
Microcontroller isolation for AC loads

Procurement Notes

Verify the specific suffix AX against the manufacturer's datasheet to confirm pinout and packaging variations. Ensure compliance with UL recognition requirements if used in certified equipment. Confirm lead times and availability directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when high current transfer ratio is required for driving relays or TRIACs directly. The Darlington output offers higher gain than standard phototransistors but exhibits slower switching speeds suitable for low-frequency AC applications.

Part Context

This part belongs to the TIL197 series of optocouplers designed for general-purpose isolation. It utilizes infrared technology to transmit signals across an insulating barrier. The DIP-4 form factor allows for easy integration into standard printed circuit board layouts.
