Overview
The Vishay 4N26-X009 is a single-channel transistor output optocoupler featuring an NPN phototransistor. It operates with a maximum collector-emitter voltage of 70 V and a collector current of 50 mA. The device provides 5000 Vrms isolation voltage and maintains a minimum current transfer ratio (CTR) of 20%. Electrical characteristics include a forward voltage of 1.5 V at 60 mA forward current, with rise and fall times of 2 µs. It functions within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via double molding technology.
- Features an NPN phototransistor output configured for standard logic interfacing.
- Designed for reliable signal transmission in environments requiring noise rejection.
Applications
- AC mains detection circuits
- Switch mode power supply feedback loops
- Telephone ring detection systems
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required isolation voltage ratings and CTR ranges for the target application. Cross-reference datasheet revision dates to confirm compliance with current environmental directives.
Selection Notes
Select this component when a 70 V collector-emitter voltage rating is required, distinguishing it from lower-voltage family members like the 4N35. Consider the 2 µs switching speed for moderate frequency applications. Verify that the 5000 Vrms isolation meets safety standards for the intended equipment class.
Part Context
This part belongs to the Vishay 4N2x-X series of industry-standard single-channel phototransistor optocouplers. These devices utilize a gallium arsenide infrared LED coupled with a silicon NPN phototransistor. The series is designed for general-purpose isolation tasks in commercial and industrial electronics.
Replacement Considerations
Direct substitutes within the same Vishay lineup include the 4N25-X009 and 4N27-X009, which share similar pinouts but may differ in current transfer ratio or voltage ratings. Verify functional equivalence before substitution.
