EL354-V

Overview

The EL354-V is a single-channel optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared LED input and an NPN phototransistor output housed in a 4-pin SOP package. The device provides 3750 Vrms isolation voltage between input and output circuits. It supports both AC and DC input signals with a typical forward voltage of 1.2V and a maximum DC forward current of 50 mA. The phototransistor output can withstand a maximum voltage of 80V. The component operates within a temperature range of -55°C to 100°C.

Feature Summary

Provides electrical insulation and impedance transformation between circuits using electro-optical conversion
Supports transmission and switching for digital logic applications
Ensures safety through fixed distance isolation between input and output

Applications

Digital logic signal transmission and conversion
Power supply control and switching circuits
Electrical isolation between circuit stages and systems

Procurement Notes

Verify the specific suffix designation, such as (TB) or (TA), against the manufacturer datasheet to confirm packaging and reel specifications. Ensure the part number matches the required isolation voltage rating of 3750 Vrms. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Cross-reference the pinout configuration to ensure compatibility with the target PCB footprint.

Selection Notes

Select this component when high isolation voltage is required for AC or DC input signals driving transistor outputs. The wide operating temperature range suits industrial environments. Verify that the 80V output voltage rating meets the load requirements. Consider the SOP-4 package dimensions for space-constrained designs requiring galvanic isolation.

Part Context

The EL354-V belongs to the EL354 series of transistor output optocouplers from Everlight Electronics. This series is designed for general-purpose isolation applications where reliable signal transfer across isolated barriers is necessary. The family includes variants with different packaging options and suffixes, all sharing the core phototransistor output architecture and high isolation capabilities.
