EL1113(TB)

Overview

The EL1113(TB) is a high-reliability optocoupler manufactured by Everlight Electronics Co., Ltd. It features a single channel with an NPN phototransistor output and includes a base terminal for enhanced performance control. The device utilizes a 5-pin long creepage SOP package designed for industrial control applications. Key electrical specifications include a maximum isolation voltage of 5000 Vrms and a maximum collector-emitter saturation voltage of 400mV. The input type is DC, ensuring stable signal transmission across the isolation barrier.

Feature Summary

• High-reliability design suitable for demanding industrial control environments
• Integrated base terminal on the NPN phototransistor output for improved switching characteristics
• 5-pin long creepage SOP package providing robust electrical isolation
• DC input configuration compatible with standard digital logic interfaces

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission between isolated circuits in automation equipment
• Power supply feedback loops for safety isolation

Procurement Notes

Verify the specific suffix (TB) against the manufacturer's current datasheet to confirm pinout and package dimensions. Ensure the component meets required isolation voltage ratings for your specific application safety standards. Check RoHS compliance status if environmental regulations apply. Confirm availability of the exact part number from authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a transistor output optocoupler with a base terminal is required for faster switching or linear operation capabilities. The 5000 Vrms isolation rating makes it suitable for high-voltage noise environments. Consider the 5-pin SOP package constraints for PCB layout space. Compare with similar models like EL1113-VG if different creepage distances are needed.

Part Context

The EL1113 series consists of phototransistor output optocouplers designed for general-purpose isolation. The EL1113(TB) variant specifically denotes the TB suffix which may relate to tape-and-reel packaging or specific manufacturing batch codes. These devices are part of Everlight's portfolio of high-reliability optoelectronic components used in various electronic systems.

Replacement Considerations

The EL1113(TB)-V is a documented substitute within the same family, offering identical functional characteristics. Verify that the replacement maintains the 5-pin long creepage SOP package and 5000 Vrms isolation rating. Ensure the base terminal functionality remains compatible with the existing circuit design.
