TIL117M

Overview

The onsemi TIL117M is a general-purpose phototransistor optocoupler featuring a single channel in a 6-pin MDIP package. It utilizes a gallium arsenide infrared emitting diode coupled to an NPN phototransistor output. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise/fall time of 2μs, and a minimum current transfer ratio of 50%. The device supports a maximum collector-emitter voltage of 30V and offers high isolation with ratings up to 7500V AC or 4170 Vrms. Operating temperatures range from -40°C to +100°C.

Feature Summary

• High-speed response suitable for digital signal transmission
• Robust insulation barrier for safety isolation
• Wide operating temperature range for industrial environments

Applications

• General purpose signal isolation
• Digital communication interface circuits
• Switching power supply feedback loops

Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct packaging and compliance status. Confirm that the procurement source provides valid traceability documentation. Check for RoHS compliance markers as indicated in manufacturer specifications. Ensure storage conditions align with moisture sensitivity levels defined in the handling guidelines. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for DC input applications. The 6-pin MDIP package facilitates through-hole mounting for robust mechanical connections. Consider the 50% minimum CTR for logic level interfacing requirements. Evaluate thermal management needs given the 100°C maximum junction temperature limit. Ensure input current limits are respected within the specified 60mA forward current rating.

Part Context

The TIL117M belongs to the TIL series of optocouplers from onsemi, designed for general-purpose isolation tasks. This series emphasizes reliability and standard pin configurations for easy integration into existing designs. The device serves as a bridge between low-voltage control circuits and higher-voltage load sides, ensuring electrical safety while maintaining signal integrity across the isolation barrier.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameter equivalence before substitution.
