TIL195A

Overview

The TIL195A is a high-density AC input phototransistor optically coupled isolator manufactured by Texas Instruments. It integrates an aluminum gallium arsenide (AlGaAs) light-emitting diode with a silicon planar phototransistor in an 8-pin DIP package. The device provides electrical isolation between circuits while transmitting signals via light. Key specifications include a minimum collector-emitter breakdown voltage of 35 V and a typical current transfer ratio of 50%. It operates within a temperature range of -40°C to +125°C and supports a maximum forward current of 50 mA.

Feature Summary

AC Input Compatibility: Designed specifically for direct connection to alternating current sources without requiring external rectification components.
High Density Packaging: Utilizes a compact 8-pin dual in-line package to maximize board space efficiency.
Optical Isolation: Provides galvanic isolation between input and output circuits using an AlGaAs LED and silicon phototransistor.

Applications

Solid-state relay driver circuits
AC mains monitoring systems
Industrial control logic interfaces

Procurement Notes

Verify the manufacturer designation carefully, as Isocom Components also produces the TIL195A under license. Confirm the specific suffix (e.g., 'A') matches the required pinout and isolation voltage ratings. Ensure the datasheet corresponds to Texas Instruments specifications if TI sourcing is mandatory, as parameter tolerances may differ between manufacturers.

Selection Notes

Select this component when direct AC drive capability is required to simplify circuit design. Consider the 35V collector-emitter breakdown voltage limit for load compatibility. Evaluate the 50% current transfer ratio against the required output signal strength. Verify thermal management requirements for operation up to 125°C.

Part Context

The TIL195A belongs to the family of high-density AC input optocouplers. It is functionally related to the TIL194A and TIL196A, which share similar packaging and isolation principles but may vary in current transfer ratio or switching speed characteristics. These devices are standard solutions for isolating low-voltage digital logic from AC power lines.

FAQ

Does the TIL195A require an external bridge rectifier for AC input?

No, the TIL195A is designed with an internal configuration that allows it to operate directly from AC input sources without additional rectification components.
