4N27G

Overview

The 4N27G is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a photovoltaic output device housed in a surface-mount package with six pins. The component supports DC input current with a maximum rating of 60 mA. Key electrical parameters include a saturation voltage (Vce) of up to 500 mV and an isolation voltage of 5300 Vrms.

Feature Summary

• Photovoltaic output configuration for signal isolation
• Surface-mount installation type for automated assembly
• High isolation voltage capability for safety separation

Applications

• Signal isolation in electronic circuits
• DC input interface applications
• General purpose optocoupler tasks

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD against official datasheets. Confirm the part status is active before procurement. Ensure the photovoltaic output type matches system requirements, as it differs from transistor outputs. Check pin count and package dimensions for PCB compatibility.

Selection Notes

Select this component when a photovoltaic output is required rather than a standard transistor or Darlington pair. Consider the 5300 Vrms isolation rating for high-voltage separation needs. Verify that the 60 mA maximum forward current meets the drive requirements of the specific application circuit.
