Overview
The onsemi 4N263S is a single-channel transistor output optocoupler featuring an NPN phototransistor. It provides high isolation with an insulation voltage of 5300 Vrms. The device operates within a temperature range of -55°C to +100°C and supports a maximum collector-emitter saturation voltage of 500 mV. It is available in SMD-DIP-6 packages, including Reel and Cut Tape configurations.
Feature Summary
- Provides electrical isolation between input and output circuits via optical transmission
- Features an NPN phototransistor output for signal switching applications
- Offers high dielectric strength for safe operation in high-voltage environments
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix (e.g., SD) against the datasheet to confirm package type and tape/reel specifications. Confirm end-of-life status as availability may be limited. Ensure RoHS compliance details match current manufacturing standards before integration into production designs.
Selection Notes
Select this component when high isolation voltage is required in a surface-mount form factor. Compare the 5300 Vrms rating against system safety requirements. Consider the NPN output configuration compatibility with downstream logic levels. Verify thermal management needs given the operating temperature range limits.
Part Context
This part belongs to the standard transistor output optocoupler family from onsemi. It serves as a legacy or alternative option to other models in the series, offering similar functionality in different packaging formats. The product line focuses on reliable signal transfer across isolated boundaries.
Replacement Considerations
Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify that any replacement maintains the 5300 Vrms isolation rating and NPN output type. Cross-reference datasheets for CTR and propagation delay differences.
