Overview
The onsemi 4N30SR2M is a single-channel, surface-mount transistor output optocoupler featuring an NPN phototransistor with base lead. It provides high isolation voltage of 4170 Vrms and supports a maximum forward current of 80 mA. The device operates within a temperature range of -40°C to +100°C and offers a typical current transfer ratio of 100%. Packaged in a 6-pin SMD configuration, it is designed for general-purpose signal isolation applications requiring robust electrical separation.
Feature Summary
- Integrates an infrared emitting diode with an NPN phototransistor having a base terminal for enhanced switching control
- Provides high-voltage electrical isolation between input and output circuits
- Designed for surface-mount technology (SMT) assembly processes
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microprocessors and logic devices
- Switching power supply feedback loops
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and packaging variations. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from onsemi before finalizing procurement plans.
Selection Notes
Select this component when surface-mount isolation is required with base-controlled output switching. Ensure the isolation voltage rating meets system safety requirements. Verify thermal management capabilities for the intended operating environment and current load conditions.
Part Context
This part belongs to the 4N3x series of optocouplers, widely used for basic isolation tasks. The SR2M suffix typically denotes a specific tape-and-reel packaging format suitable for automated assembly lines, distinguishing it from DIP variants.
Replacement Considerations
Direct substitutes include other 4N30 series variants such as 4N30 or 4N35 if package compatibility allows. Verify pinout alignment and isolation voltage ratings when considering alternative manufacturers' equivalents.
