EL1013(TA)-G

Overview

The EL1013(TA)-G is a transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a continuous output current of 50mA per channel. The device provides electrical isolation with a rated RMS voltage of 5000Vrms across one channel. Key performance metrics include a minimum current transfer ratio of 100% and a maximum of 200% at a forward current of 10mA. The saturation voltage is specified at a maximum of 300mV. The component operates within a temperature range of -55°C to 110°C and utilizes a 4-pin SOP package with a 2.54mm pitch.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using infrared LED and NPN phototransistor technology.
• Offers reliable signal transmission with defined current transfer ratios for consistent logic level interfacing.
• Designed for surface mount assembly in compact electronic systems requiring galvanic separation.

Applications

• Industrial control system signal isolation
• Power supply feedback loop monitoring
• Microcontroller interface protection

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation, as variations such as VG exist with potential physical differences like lead frame thickness. Confirm availability status through authorized distributors, as supply constraints may apply. Ensure compliance with RoHS3 standards if required by the end product specifications. Check moisture sensitivity levels for proper handling during storage and reflow processes.

Selection Notes

Select this component when a single-channel transistor output optocoupler with 5000Vrms isolation is required. Consider the 50mA output current capability and 80V collector-emitter voltage limits for circuit design. Evaluate the 100-200% current transfer ratio range to ensure adequate signal coupling efficiency. Verify that the 4-SOP package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to Everlight's family of SMD/SMT photocouplers designed for surface mount applications. It shares functional similarities with other models like the EL1013-G but includes specific suffixes indicating packaging or material variations. The TA suffix typically denotes specific tape and reel packaging configurations used in automated assembly lines.

Replacement Considerations

The EL1013(TA)-VG is noted as a variant with no change in function but increased lead frame thickness. Direct substitution requires verifying package compatibility and ensuring the thicker leads do not interfere with existing board clearance requirements.
