4N26-X001

Overview

The Vishay Semiconductor Opto Division 4N26-X001 is a single-channel phototransistor optocoupler housed in a 6-DIP package. It provides 5000Vrms isolation voltage between input and output circuits. The device features a typical forward voltage of 1.36V and a maximum DC forward current of 60mA. Output characteristics include a collector-emitter saturation voltage of 500mV and an output current capability of 50mA per channel.

Feature Summary

• Single-channel optical isolation using a phototransistor output
• High isolation voltage rating for circuit separation
• Standard through-hole DIP packaging for easy integration

Applications

• General-purpose signal isolation
• Logic level shifting
• Switching applications requiring galvanic isolation

Procurement Notes

Verify the specific suffix -X001 to ensure correct packaging and variant alignment with design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference datasheet electrical limits against system operating conditions to ensure reliability under thermal and electrical stress.

Selection Notes

Select this component when single-channel isolation with a phototransistor output is required. Consider the 5000Vrms isolation rating and 6-DIP form factor for compatibility with existing board layouts. Evaluate switching speed and current transfer ratio against application timing constraints before finalizing the choice.

Part Context

The 4N26 belongs to the industry-standard 4N25 family of single-channel phototransistor couplers, which also includes variants like the 4N25, 4N27, and 4N28. This family is widely recognized for general-purpose isolation tasks. The 4N26-X001 specifically denotes the version packaged in a 6-DIP configuration.

Replacement Considerations

Compatible substitutes within the same family include the 4N25, 4N27, and 4N28. Verify pinout compatibility and electrical parameter equivalence when substituting these parts.
