Overview
The 4N28FR2VM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and provides high isolation capability with an insulation voltage of 7500 Vrms. The device is housed in a 6-SMD surface-mount package, designed for compact circuit layouts. This component serves as a reliable interface for signal transmission while maintaining electrical isolation between input and output circuits.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Features an NPN phototransistor output stage for signal switching
- Utilizes a compact 6-SMD surface-mount package design
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits requiring high voltage isolation
- Power supply feedback loops
Procurement Notes
Verify the current lifecycle status before procurement, as availability may be restricted. Confirm that the 6-SMD package variant matches the PCB footprint requirements. Ensure compliance with relevant material regulations such as RoHS standards for the specific manufacturing batch. Check for any regional sales restrictions or distribution limitations applicable to this part number.
Selection Notes
Select this component when a standard transistor output optocoupler with high isolation voltage is required in a surface-mount form factor. Consider the 7500 Vrms insulation rating for applications demanding robust electrical separation. Evaluate the NPN output configuration against system logic requirements. Verify that the physical dimensions of the 6-SMD package fit within the available board space constraints.
Part Context
This device belongs to the family of transistor output optocouplers from onsemi. These components are widely used for providing galvanic isolation in electronic circuits. The 4N28 series is a legacy designation often replaced by newer equivalents, but remains relevant for designs specifying this particular pinout and performance profile.
Replacement Considerations
Cross-reference with other 6-pin SMD transistor output optocouplers if direct substitution is needed. Verify pin compatibility and isolation voltage ratings against alternative manufacturers' offerings.
