Overview
The onsemi 4N25SR2M is a high-reliability optoisolator designed to provide robust galvanic isolation between electronic circuits. Its primary function is to transfer signals via light, preventing ground loops and protecting sensitive downstream components from voltage transients. A critical design consideration is the trade-off between input forward current and output current transfer ratio (CTR); achieving the specified 20% minimum CTR necessitates careful selection of the input drive current, balancing power consumption with signal integrity, especially in noise-sensitive applications.
Key Features
- Isolation Voltage: 4170Vrms
- Channels: 1
- Output Type: Transistor with Base
- CTR (Min): 20% @ 10mA
- Switching Speed (Typ): 2µs, 2µs
- Package: 6-SMD, Gull Wing (Surface Mount)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Interfacing low-voltage microcontrollers with high-voltage AC line circuits.
- Signal isolation in industrial automation control systems.
- Noise suppression in sensitive analog measurement equipment.
- Providing safe coupling for power supply control loops.
