TIL191A

Overview

The TIL191A is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It integrates an infrared light-emitting diode with an NPN silicon phototransistor in a 4-pin DIP package. The device provides electrical isolation with a rated voltage of 5300Vrms. 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 supports a maximum input current of 50mA and operates within a temperature range of -55°C to 100°C.

Feature Summary

Integrates an infrared LED with an NPN silicon phototransistor for signal transmission
Provides high-voltage electrical isolation between input and output circuits
Designed for through-hole mounting in a standard 4-pin dual in-line package

Applications

General-purpose signal isolation in electronic circuits
Industrial control systems requiring galvanic separation
Power supply feedback loops

Procurement Notes

Verify the specific manufacturer designation and datasheet version before procurement. Confirm that the component meets all required environmental specifications for the intended operating temperature range. Ensure compatibility with existing PCB footprint dimensions and soldering profiles. Cross-reference part numbers carefully to distinguish between similar variants within the TIL197 series or other Isocom product lines.

Selection Notes

Select this component when high isolation voltage and robust NPN transistor output are required. Consider the relatively slow switching speeds compared to faster logic-output optocouplers. Evaluate the thermal management requirements given the wide operating temperature range. Ensure the application does not demand AC input characteristics found in other series members.

Part Context

The TIL191A belongs to the TIL197 series of optocouplers from Isocom Components 2004 LTD. This series focuses on providing reliable optical isolation using standard NPN phototransistor outputs. The company specializes in infrared optoelectronic devices, offering various packages and configurations for different industrial applications.
