EL1017(TA)-VG(DGK)

Overview

The EL1017(TA)-VG(DGK) is a single-channel optoisolator manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output and provides 5000Vrms isolation voltage. The device utilizes a 4-SOP package with a 2.54mm pitch. Key electrical parameters include a minimum Current Transfer Ratio of 80% and a maximum of 160%, both measured at a forward current of 5mA.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for signal transmission
• Designed for surface-mount assembly in compact layouts

Applications

• General-purpose digital signal isolation
• Microcontroller interface circuits
• Switching power supply feedback loops

Procurement Notes

Verify the specific suffix (DGK) against the manufacturer's official documentation to confirm packaging details and compliance certifications. Ensure the ordering part number matches the required tape-and-reel specifications. Cross-reference the datasheet revision date to guarantee parameter accuracy during procurement.

Selection Notes

Select this component when a standard transistor output optocoupler with 5000Vrms isolation is required. The 4-SOP package suits applications needing a small footprint. Verify that the CTR range of 80-160% meets the circuit drive requirements at the intended operating current.

Part Context

This part belongs to the EL1017 family of long creepage SOP phototransistor photocouplers. The DGK suffix typically denotes specific packaging or regulatory compliance variations within the Everlight product line. It serves as a general-purpose isolator for industrial and consumer electronics.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Generic replacements must match the 4-SOP package, NPN output type, and 5000Vrms isolation rating. Verify pinout compatibility before implementation.
