EL3H4(A)(EB)-G

Overview

The EL3H4(A)(EB)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides an isolation voltage of 3750 Vrms. The device operates within a temperature range of -55°C to +100°C. It utilizes a surface-mount 4-SSOP package with dimensions of 4.40 x 2.70 mm and a height of 2.00 mm. Key electrical parameters include a maximum collector-emitter voltage of 80V, a forward current of 50mA, and a typical forward voltage of 1.2V.

Feature Summary

Provides high-voltage isolation capability for signal transmission between isolated circuits
Features a compact surface-mount design suitable for automated assembly processes
Utilizes an NPN phototransistor output configuration for standard switching applications

Applications

Industrial control systems requiring galvanic isolation
Communication equipment interface circuits
Power supply feedback loops

Procurement Notes

Verify the specific suffix (EB) against the manufacturer's latest documentation to confirm package type and availability status. Check for RoHS compliance details and moisture sensitivity level requirements before integration into production lines. Ensure the component meets all environmental operating specifications for the intended application environment.

Selection Notes

Select this component when a single-channel isolation solution with a 3750 Vrms rating is required. Consider the NPN output type and SSOP package constraints. Evaluate the operating temperature range and electrical characteristics against circuit requirements to ensure compatibility with the system design.

Part Context

This part belongs to the EL3H4 series of transistor output optocouplers from Everlight Electronics. The series is designed for general-purpose isolation applications. Variations in suffixes typically denote differences in packaging or specific manufacturing batches, while maintaining core electrical performance characteristics defined by the base model number.
