TIL192B

Overview

The TIL192B is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It integrates an infrared emitting diode with an NPN silicon phototransistor to provide electrical isolation between input and output circuits. The device features a dual-channel configuration housed in an 8-pin DIP package, designed for compact mounting applications. Key electrical specifications include a maximum forward current of 50 mA and a rise time of 6 µs. The unit offers robust isolation capabilities with ratings of 5300 VRMS and 7500 VRMS, ensuring reliable signal transmission across isolated boundaries while maintaining low power consumption.

Feature Summary

• Dual-channel architecture for simultaneous signal isolation
• High-density packaging suitable for space-constrained designs
• Robust voltage isolation rating for safety compliance

Applications

• Industrial control systems requiring signal isolation
• Communication interfaces needing galvanic separation
• Power supply feedback loops for noise reduction

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as variations exist between through-hole DIP and surface-mount SMD configurations. Ensure the selected variant matches the required isolation voltage rating and channel count for the target application. Cross-reference the manufacturer's latest datasheet to confirm active status and availability before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required within a standard 8-pin footprint. Consider the 5300 VRMS rating for general industrial isolation needs. Evaluate the 6 µs rise time against system speed requirements. Compare against legacy equivalents if replacing discontinued parts from other manufacturers.
