EL1013(TB)

Overview

The EL1013(TB) is a single-channel phototransistor optocoupler manufactured by Everlight Electronics. It features a surface-mount SOP-4 package with long creepage distance, providing 5000 Vrms isolation voltage between input and output. The device utilizes an NPN phototransistor output capable of handling up to 80V collector-emitter voltage and 50mA collector current. Key electrical characteristics include a forward voltage of approximately 1.45V at 10mA forward current and a power dissipation rating of 250mW. It operates within a temperature range of -55°C to +110°C.

Feature Summary

• High isolation voltage capability of 5000 Vrms for safe signal transmission across potential differences
• Long creepage distance design in SOP-4 package enhances safety and reliability
• NPN phototransistor output configuration suitable for digital switching applications

Applications

• Signal isolation in industrial control systems
• Interface circuits between microcontrollers and high-voltage loads
• Power supply feedback loops for noise immunity

Procurement Notes

Verify the specific suffix (TB) against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compliance with RoHS directives if required by your application standards. Cross-reference the part number with official Everlight documentation to distinguish it from similar variants like EL1013(TA) or EL1013(D). Confirm availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when high isolation voltage and compact surface-mount packaging are required. The NPN output type is ideal for sinking current in logic interfaces. Consider the 50mA output current limit and 80V voltage rating to ensure compatibility with downstream circuitry requirements. Evaluate thermal management needs given the 250mW power dissipation rating in enclosed spaces.

Part Context

This part belongs to Everlight's EL101x series of general-purpose phototransistor optocouplers. The series offers various package options including DIP and SOP formats. The TB suffix typically denotes a specific tape-and-reel packaging variant or creepage specification within the SOP-4 family, designed for automated assembly processes.

Replacement Considerations

Direct replacements may include other 5kV isolated SOP-4 phototransistor optocouplers from manufacturers such as Vishay or Broadcom, provided they match the pinout and electrical ratings. Verify that substitute parts maintain equivalent isolation voltage and current transfer ratio specifications.
