TIL117VM

Overview

The TIL117VM is a single-channel transistor-output optocoupler from onsemi, housed in a 6-pin MDIP package. It features a GaAs infrared LED input and an NPN phototransistor output with a base lead for enhanced switching performance. Key electrical parameters include a 7500Vrms isolation voltage, a minimum current transfer ratio (CTR) of 50% at 10mA forward current across the -40°C to 100°C temperature range, and a typical rise/fall time of 2µs. The device supports a maximum forward current of 60mA and offers a collector-emitter saturation voltage of 400mV.

Feature Summary

• Integrated base lead on the phototransistor output to improve switching speed and reduce storage time.
• High isolation capability with 7500Vrms dielectric strength between input and output circuits.
• Guaranteed current transfer ratio maintained across the full industrial operating temperature range.

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Signal isolation in microprocessor-based interfaces

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as suffixes may indicate tape-and-reel or tube packaging options. Confirm RoHS compliance status through official manufacturer declarations. Cross-reference the datasheet revision date to ensure alignment with current design specifications. Validate that the selected component meets all thermal and electrical requirements for the target application environment before finalizing procurement.

Selection Notes

Select the TIL117VM when high-speed switching is required compared to standard phototransistor outputs, due to its base lead configuration. Ensure the circuit design accommodates the 60mA maximum forward current limit. Verify that the 7500Vrms isolation rating exceeds the system's working voltage requirements. Consider the 6-DIP package dimensions for PCB layout constraints and verify compatibility with automated assembly processes if applicable.

Part Context

The TIL117VM belongs to onsemi's TIL series of optocouplers, designed for general-purpose isolation applications. It complements other devices in the family by offering improved switching characteristics through its base-driven output structure. This component serves as a reliable solution for bridging low-voltage digital logic with higher-voltage analog or power circuits in industrial environments.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should consult the manufacturer's official replacement guide or contact technical support for validated cross-reference data. Ensure any alternative component matches the pinout, isolation voltage, and CTR specifications to maintain circuit functionality.

FAQ
