EL213(TA)

Overview

The EL213(TA) is a transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode coupled to an NPN phototransistor in an 8-pin SOP package. Key electrical specifications include a collector-emitter breakdown voltage of 80 V, a maximum input forward current of 60 mA, and a collector current rating of 50 mA. The device provides an insulation voltage of 3750 Vrms and operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides electrical isolation between input and output circuits via optical coupling
• Integrates an infrared LED emitter with an NPN phototransistor detector
• Designed for surface mount assembly using standard reflow soldering processes

Applications

• Signal isolation in industrial control systems
• Power supply feedback loops
• Microcontroller interface circuits requiring galvanic isolation

Procurement Notes

Verify the specific suffix (e.g., TA, TA-V) against the manufacturer's official datasheet to confirm pinout configuration and packaging type. Ensure the component meets required insulation voltage ratings for the target application safety standards. Confirm availability status as product lifecycles may change.

Selection Notes

Select this component when high isolation voltage is required in a compact surface mount footprint. Compare the 80V collector-emitter breakdown voltage and 50mA collector current against circuit load requirements. Consider the 3750Vrms insulation rating for safety-critical applications involving mains or high-voltage separation.

Part Context

This part belongs to Everlight's family of transistor output optocouplers designed for general-purpose isolation. The 8-pin SOP format allows for automated placement and reduced board space compared to through-hole alternatives. These devices are commonly used where signal integrity must be maintained across electrically noisy environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative optocouplers based on CTR, isolation voltage, and package dimensions before substitution.
