Overview
The 4N27SVM is a single-channel optocoupler manufactured by onsemi. It integrates an AlGaAs infrared LED emitter with an NPN phototransistor detector, providing electrical isolation between input and output circuits. The device is housed in a standard DIP-6 package, designed for robust signal transmission across isolated boundaries while maintaining high reliability and safety compliance for industrial applications.
Feature Summary
- Integrates an AlGaAs infrared LED with an NPN phototransistor for efficient optical coupling
- Provides galvanic isolation to protect sensitive control circuits from high-voltage noise
- Features a standard six-pin dual in-line package for easy integration into existing PCB layouts
Applications
- Industrial automation control systems
- Power supply feedback loops
- Signal isolation in microcontroller interfaces
Procurement Notes
Verify the specific suffix 'SVM' against official onsemi documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with required isolation voltage ratings for your specific application environment before finalizing procurement orders.
Selection Notes
Select this component when a cost-effective, general-purpose optocoupler is needed for basic digital signal isolation. Consider the CTR (Current Transfer Ratio) variations and propagation delay characteristics if precise timing or high-speed switching requirements exist within the target system design.
Part Context
This part belongs to the widely used 4N2x series of optocouplers, which are industry-standard components for isolation tasks. The 4N27 variant specifically offers a balance of speed and isolation performance, making it a common choice for legacy and modern designs requiring reliable signal transfer across isolated domains.
Replacement Considerations
Direct pin-compatible replacements include the 4N25 and 4N26, though their Current Transfer Ratio and bandwidth specifications differ. Verify that any substitute meets the minimum isolation voltage and operating temperature range required by the original design constraints.
