IL4116-X019T

Overview

The IL4116-X019T is a single-channel Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an SMD-6 surface mount package designed for high-voltage isolation applications. The device provides an insulation voltage of 5300 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a maximum continuous output current of 300 mA and a peak off-state voltage (VDRM) of 650 V. The component operates with a forward current of 60 mA and dissipates up to 500 mW of power. It supports a wide operating temperature range from -55°C to +100°C.

Feature Summary

• Integrated zero-crossing detection circuitry for reduced electromagnetic interference during switching
• High isolation voltage capability suitable for demanding industrial environments
• Surface-mount construction optimized for automated assembly processes

Applications

• Solid-state relay modules requiring precise AC load control
• Industrial motor control systems utilizing triac-based switching
• Power supply units with isolated gate drive requirements

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact binning or revision status. Confirm RoHS compliance details directly with the supplier as regulatory statuses may vary by production batch. Ensure that the SMD-6 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when high-voltage isolation combined with zero-crossing functionality is required for AC loads. Evaluate the 650 V peak off-state voltage against the maximum line voltage in the application. Consider the 300 mA continuous current rating to ensure adequate headroom for the intended load profile without exceeding thermal limits.

Part Context

This part belongs to the Vishay IL4116 series of optoisolators, which are engineered for controlling triacs and SCRs in isolated environments. The series emphasizes safety and reliability in power electronics. The X019T suffix typically denotes specific packaging or tape-and-reel configurations within the broader product family.

Replacement Considerations

Public records indicate that the IL4116-X019T variant is obsolete and no longer manufactured. Designers should consult Vishay's official obsolescence notices for recommended alternative parts that maintain compatible pinouts and electrical specifications.
