4N26W

Overview

The 4N26W is a photovoltaic output optoisolator manufactured by onsemi. It features a single channel with DC input and photovoltaic output type. The device provides an isolation voltage of 5300 Vrms. It is housed in a 6-DIP package with a width of 0.400 inches (10.16mm). The component supports through-hole mounting and operates within a temperature range of -40°C to 100°C.

Feature Summary

• Photovoltaic output architecture for galvanic isolation
• High insulation voltage rating for safety applications
• Single-channel configuration with base terminal access

Applications

• Industrial control systems requiring signal isolation
• Microcontroller interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet, as the 4N26 series has multiple variants. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) regarding assembly or material updates before finalizing procurement specifications.

Selection Notes

Select this component when high isolation voltage and photovoltaic output are required. Ensure the application can accommodate the open-collector nature of the photovoltaic output stage. Verify that the DIP-6 package dimensions fit the target PCB layout constraints and thermal requirements.

Part Context

The 4N26W belongs to the broader 4N26 family of optocouplers produced by onsemi. This family includes various output types such as transistor and photodarlington configurations. The 4N26W specifically utilizes a photovoltaic output structure, distinguishing it from other members like the 4N26TVM which uses a transistor output.
