EL357N(TB)-VG

Overview

The EL357N(TB)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features a 4-pin SOP (2mm) surface mount package with a 2.54mm pitch. The device provides 3750Vrms isolation voltage between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a DC forward current of 50mA, and a typical forward voltage of 1.2V. The output current per channel is rated at 50mA. Operating temperature range spans from -55°C to 110°C.

Feature Summary

Provides high-voltage electrical isolation via infrared LED and phototransistor coupling
Compact 4-pin SOP surface mount design for dense PCB layouts
Wide operating temperature range suitable for industrial environments

Applications

Industrial control systems signal isolation
Power supply feedback loop isolation
Digital logic interface circuits

Procurement Notes

Verify the specific suffix TB against official Everlight documentation to confirm pinout configuration and lead material specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm availability status as distribution channels may vary. Cross-reference datasheet revisions to ensure parameter consistency before integration into final designs.

Selection Notes

Select this component when compact size and high isolation voltage are required for single-channel applications. The 80V output rating suits low-to-medium voltage switching tasks. Verify that the 50mA output current capability meets load requirements. Consider the 2mm body height constraint for assembly clearance. Compare CTR ranges if precise gain control is necessary for the specific application circuit.

Part Context

This part belongs to the EL357N-G series of transistor output optocouplers. The series is designed for general-purpose isolation in space-constrained applications. Everlight utilizes advanced packaging techniques to achieve small form factors while maintaining robust electrical performance standards for industrial and consumer electronics markets.
