IL4118-X006

Overview

The Vishay IL4118-X006 is a phototriac output optocoupler featuring an integrated zero-crossing detection circuit. It provides electrical isolation between input and output circuits with a rated insulation voltage of 5300 Vrms. The device utilizes a six-pin DIP package and includes a high-sensitivity LED input driven by an emitter follower configuration. Key electrical parameters include a peak repetitive off-state voltage (VDRM) of 850 V, a maximum continuous output current of 300 mA, and a forward voltage of 1.3 V at 60 mA forward current.

Feature Summary

• Integrated zero-crossing detection circuit for reduced electromagnetic interference during switching
• High input sensitivity achieved through an internal emitter follower configuration
• Robust galvanic isolation capability suitable for AC power control applications

Applications

• Solid-state relays for AC load switching
• Motor speed control circuits
• Lighting dimmer controls

Procurement Notes

Verify the specific suffix X006 to confirm the six-pin DIP packaging variant. Confirm RoHS compliance status as required by regional regulations. Ensure the selected component matches the required insulation voltage rating for the target application safety standards. Cross-reference the manufacturer datasheet for exact mechanical dimensions and thermal characteristics before finalizing procurement.

Selection Notes

Select this component when zero-crossing switching is required to minimize inrush currents and noise in AC systems. The 850 V blocking voltage supports standard mains voltage applications. Consider the 300 mA output current limit for load sizing. The DIP-6 package facilitates through-hole mounting on printed circuit boards. Verify compatibility with the driving logic levels due to the specific input sensitivity characteristics.

Part Context

The IL4118 series belongs to Vishay's family of triac and SCR output optocouplers designed for AC power control. These devices integrate a phototriac detector with zero-crossing logic on a single monolithic chip. The series offers various package options, including surface mount and dual in-line configurations, to accommodate different assembly requirements while maintaining high isolation performance.

Replacement Considerations

IL4118-X001 is listed as a parametric equivalent substitute. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement part meets the same insulation voltage and current ratings.
