TIL111TM

Overview

The onsemi TIL111TM is a single-channel, through-hole optocoupler featuring an infrared LED input and a phototransistor output with a base terminal. It utilizes a 6-pin MDIP package for standard mounting. Key electrical specifications include a maximum forward voltage of 1.4V, a typical rise time of 2μs, and a maximum input current of 60mA. The device provides an isolation voltage of 7500Vrms, ensuring robust signal transmission between isolated circuits while maintaining high reliability in industrial applications.

Feature Summary

• Integrates an infrared emitter with a phototransistor output including a base pin for enhanced control capabilities
• Provides high-voltage isolation to protect sensitive circuitry from noise and potential differences
• Designed for direct coupling with logic families such as TTL and CMOS interfaces

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission between microcontrollers and peripheral devices
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix (e.g., M) against the manufacturer's official datasheet to confirm package type and tape/reel configuration. Ensure the procurement order matches the exact part number variant to avoid discrepancies in lead times or packaging quantities. Cross-reference the isolation voltage rating with system requirements before finalizing the purchase order.

Selection Notes

Select this component when a phototransistor output with a base terminal is required for improved switching speed or gain control. Compare the 7500Vrms isolation rating against the system's safety standards. Consider the 60mA maximum input current limit when designing the driving circuit to ensure optimal LED performance without exceeding absolute maximum ratings.

Part Context

This component belongs to the general category of transistor-output optocouplers manufactured by onsemi. It serves as a standard solution for digital signal isolation in environments where electrical noise immunity is critical. The device replaces older equivalents in legacy designs while offering consistent performance characteristics for modern electronic assemblies.

Replacement Considerations

Check for compatible substitutes within the same family that share identical pinouts and electrical parameters. Verify that any alternative component maintains the 7500Vrms isolation rating and similar rise time specifications to ensure circuit compatibility.
