EL1018(TB)-V

Overview

The EL1018(TB)-V is a single-channel optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode coupled to a phototransistor output, housed in a 4-pin SOP package with long creepage distance. The device provides electrical isolation with a rated isolation voltage of 5000 Vrms. Key electrical parameters include a maximum forward current of 60 mA and a collector-emitter voltage of 80 V. The component operates within a temperature range of -55 °C to 110 °C and has a power dissipation rating of 250 mW.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a phototransistor output configuration for signal transmission
• Designed with a long creepage distance in the SOP-4 package

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Switching applications requiring galvanic isolation

Procurement Notes

Verify the specific suffix (TB) indicates tape and reel packaging when ordering. Confirm the VDE certification status if required for safety compliance in your application. Ensure the supplier source matches the manufacturer's official distribution channels to guarantee authenticity. Check for any recent product change notifications regarding pinout or material composition updates from Everlight Electronics.

Selection Notes

Select this component when a standard NPN phototransistor output is needed with high isolation voltage requirements. The long creepage SOP package is suitable for PCBs requiring enhanced clearance distances. Consider the switching speed characteristics, which are typical for general-purpose isolation rather than high-speed data transmission. Verify that the 60 mA forward current limit meets the drive requirements of the connected LED circuit.

Part Context

This part belongs to the EL1018 family of optocouplers, which are widely used for basic isolation tasks. The TB suffix typically denotes tape and reel packaging, while VG may indicate specific environmental or regulatory compliance attributes defined by the manufacturer. This series is distinct from high-speed variants like the EL1019 or digital isolators.

Replacement Considerations

Direct replacements must match the 4-pin SOP footprint and phototransistor output type. Verify compatibility with the 5000 Vrms isolation rating. Cross-reference with other manufacturers' equivalents such as PC123 or H11L1 only after confirming pinout and electrical parameter alignment.
