EL357N(C)(TA)-VG

Overview

The EL357N(C)(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features a 4-SOP surface mount package with a 2.54mm pin pitch. The device provides an isolation voltage of 3750Vrms and supports a collector-emitter voltage of 80V. Key electrical parameters include a maximum DC forward current of 50mA, a typical forward voltage of 1.2V, and a saturation voltage of 200mV. The current transfer ratio ranges from 200% to 400% at 5mA input. Switching characteristics consist of typical rise and fall times of 3µs and 4µs respectively. It operates within a temperature range of -55°C to 110°C.

Feature Summary

Procurement Notes

Verify the specific suffix (C)(TA)-VG against the manufacturer datasheet to ensure correct packaging and compliance status. Confirm RoHS3 compliance requirements match project specifications. Check for active status as some variants may be obsolete. Ensure the supplier provides original manufacturer documentation for quality assurance.

Selection Notes

Select this component when a single channel with 3750Vrms isolation is required in a small footprint. Consider the 50mA collector current limit and 80V breakdown voltage for load compatibility. The NPN phototransistor output suits standard logic interface designs. Verify thermal performance within the specified operating temperature range for the target environment.

Part Context

This part belongs to the EL357N series of transistor output optocouplers from Everlight. The series is designed for general-purpose isolation tasks. Variants differ primarily in packaging format and tape/reel specifications. The base EL357N model establishes the core electrical characteristics shared across the family.

Replacement Considerations

Direct substitutes include other single-channel transistor optocouplers with similar 3750Vrms isolation and SOP-4 packages. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with manufacturer replacement guides for confirmed equivalents.
