Overview
The EL357NE(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and a phototransistor detector within a compact SOP-4 surface-mount package. The device provides electrical isolation with a rated RMS voltage of 3750V. Key electrical parameters include a maximum collector-emitter voltage of 80V, a forward current of 50mA, and a total power dissipation of 200mW. The unit operates across a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared light transmission.
- Features a compact four-pin small outline package designed for dense printed circuit board layouts.
- Delivers fast switching response times suitable for signal transmission in control applications.
Applications
- Industrial control systems requiring signal isolation
- Communication equipment interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact performance grades and compliance status. Ensure the ordering information matches the required isolation voltage and package type specifications for your design. Confirm RoHS compliance details directly from the source documentation before finalizing procurement decisions.
Selection Notes
Select this component when a single-channel transistor output isolator is required for low-to-medium speed signal transfer. The SOP-4 form factor is appropriate for space-constrained designs. Verify that the 80V collector-emitter voltage rating meets the load requirements and that the 3750Vrms isolation level satisfies safety standards for the intended application environment.
Part Context
This part belongs to the EL357N series of optocouplers produced by Everlight Electronics. The series utilizes a standard phototransistor output architecture housed in a surface-mount format. The specific model variant denotes the packaging tape configuration and compliance markings defined by the manufacturer's internal coding system.
Replacement Considerations
Consult official substitution lists for compatible equivalents. Cross-reference pinouts and electrical ratings carefully when considering alternative manufacturers or different suffix variants within the same product family.
