TIL193

Overview

The TIL193 is a high-density phototransistor optically coupled isolator manufactured by Isocom Components 2004 LTD. It integrates an infrared LED with an NPN silicon phototransistor to provide electrical isolation. The device features four independent channels within a single package, offering 5300Vrms isolation voltage. It supports a maximum DC forward current of 60 mA and delivers up to 50 mA output current per channel. The unit operates across a temperature range of -55°C to 100°C and utilizes a 16-pin DIP configuration for through-hole mounting.

Feature Summary

• Integrates four independent optical channels within a compact high-density package
• Provides robust electrical isolation between input and output circuits
• Utilizes an NPN silicon phototransistor for reliable signal transmission

Applications

• High-density multi-channel data communication interfaces
• Industrial control systems requiring multiple isolated signals
• Power supply feedback loops in multi-rail designs

Procurement Notes

Verify the specific suffix variant against official documentation, as packaging formats such as tube or tape-and-reel may differ. Confirm that the required isolation voltage and channel count align with system specifications. Ensure compatibility with through-hole assembly processes given the DIP package type. Cross-reference regulatory compliance status if operating in restricted environments.

Selection Notes

Select this component when multiple isolated channels are required in a single footprint. The high isolation rating suits applications involving significant potential differences. Consider the rise and fall times for signal integrity requirements. Evaluate thermal management needs based on the specified operating temperature range and power dissipation characteristics.
