TIL191B

Overview

The TIL191B is a single-channel optoisolator manufactured by Isocom Components 2004 LTD, featuring a transistor output configuration. It provides an isolation voltage of 5300Vrms and supports a maximum forward current of 50mA with a reverse voltage rating of 6V. The device operates within a total power dissipation limit of 200mW. Electrical parameters include a typical rise time of 2µs and a typical fall time of 11µs. The component utilizes a 4-pin DIP package and is designed for DC input applications.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits
Utilizes a standard transistor output structure for signal switching
Designed for reliable operation in general-purpose digital isolation tasks

Applications

General-purpose digital signal isolation
Interface circuits requiring galvanic separation
Microcontroller I/O protection

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required packaging formats, such as tape and reel options available for automated assembly processes. Confirm that the 4-pin DIP package variant matches the intended PCB footprint constraints. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a robust, single-channel isolation solution with a transistor output is required. Consider the 5300Vrms isolation rating for safety-critical applications. Evaluate the 50mA forward current capability against the driving source limitations. Ensure the 4-pin DIP form factor aligns with existing board space requirements and manual or semi-automated assembly workflows.
