EL3H7(J)-VG

Overview

The EL3H7(J)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. 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 +110°C. Key electrical parameters include a maximum collector-emitter voltage of 80V, a maximum DC forward current of 50mA, and a typical forward voltage of 1.2V. The unit is housed in a compact 4-SSOP surface-mount package.

Feature Summary

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

Applications

• Industrial control systems requiring signal isolation
• Consumer electronics with safety isolation requirements
• Computer peripheral interface circuits

Procurement Notes

Verify the specific Current Transfer Ratio (CTR) bin associated with the suffix J, as performance varies across the EL3H7 family. Confirm RoHS compliance status and packaging options such as tape and reel or cut tape directly with the manufacturer or authorized distributors before ordering.

Selection Notes

Select this component when a small form factor is required alongside standard transistor output characteristics. Ensure the application voltage does not exceed the 80V collector-emitter rating. Consider the operating temperature range if deployed in extreme environmental conditions.

Part Context

This part belongs to the EL3H7 series of ultra-small SSOP optocouplers from Everlight. The series offers various CTR bins to accommodate different sensitivity requirements while maintaining a consistent physical footprint and isolation voltage specification across all variants.

Replacement Considerations

Direct substitutes may include other parts from the EL3H7 family with compatible CTR ranges, such as EL3H7(B)(TA)-VG or EL3H7(C)(TB)-VG, provided the specific gain requirements are met.
