IL4117

Overview

The IL4117 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a phototriac output. It provides an isolation voltage of 5300Vrms and is housed in a 6-DIP package. Key electrical parameters include a maximum off-state voltage of 700V and a minimum static dV/dt rating of 10kV/µs. The device supports a maximum LED trigger current (Ift) of 1.3mA.

Feature Summary

• High isolation voltage capability for robust circuit protection
• Fast switching speed with high static dV/dt immunity
• Low input current requirement for efficient drive

Applications

• Solid-state relay interfaces
• Motor control circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix code to ensure correct packaging and variant selection. Confirm that the 5300Vrms isolation rating meets system safety standards. Check RoHS compliance status for environmental regulations. Ensure the 6-DIP package dimensions fit the target PCB layout constraints before ordering.

Selection Notes

Select this component when high voltage isolation and fast triac triggering are required. The low Ift specification allows for direct interfacing with microcontrollers or logic gates without excessive current draw. Consider the 700V off-state voltage for mains-level applications. Evaluate thermal management requirements based on the operating temperature range specified in the datasheet.

Part Context

This part belongs to Vishay's IL series of phototriac output optocouplers. These devices are designed for general-purpose AC load switching applications. The series offers various isolation voltages and package options to suit different industrial and consumer electronics needs.

Replacement Considerations

Check for equivalent parts with similar 5300Vrms isolation and 700V Vdrm ratings. Verify pinout compatibility for DIP-6 packages. Ensure replacement devices meet the same static dV/dt and Ift specifications to maintain circuit performance.
