Onsemi 4N25SR2M

The Onsemi4N25SR2M is an optoisolator, also known as an optocoupler, which is used to transfer electrical signals between two isolated circuits while keeping them electrically isolated. It consists of a light-emitting diode (LED) and a phototransistor enclosed in a single package. Functions: The main function of the Onsemi4N25SR2M is to provide isolation between input and output circuits, preventing any direct electrical connection. The LED emits light when current flows through it, which is then detected by the phototransistor, causing it to conduct. This action enables electrical signals to be transmitted across the isolation barrier. Applications: The Onsemi4N25SR2M is commonly used in applications where electrical isolation is required, such as: 1. Power supply feedback control circuits. 2. AC motor control in industrial machinery. 3. Instrumentation and measurement systems. 4. Audio and video signal transmission. 5. Medical devices. Alternative parts: If the Onsemi4N25SR2M is not available or suitable for your specific requirements, here are a few alternative optoisolators you can consider: 1. Vishay VOM1271T 2. Broadcom HCPL-817-000E 3. Fairchild FOD817B Embedded modules: The Onsemi4N25SR2M is available as a discrete component and is not typically integrated into specific embedded modules. However, it can be used as a building block in various embedded systems and circuit designs that require electrical isolation. Q&A: 1. What is the maximum voltage rating for the Onsemi4N25SR2M? Answer: The maximum voltage rating for the Onsemi4N25SR2M is typically around 500V. 2. Can the Onsemi4N25SR2M be used for high-speed data transmission? Answer: No, the Onsemi4N25SR2M is not suitable for high-speed data transmission due to its limited bandwidth. It is more commonly used for low to moderate speed signal isolation. 3. Is the Onsemi4N25SR2M compatible with both AC and DC signals? Answer: Yes, the Onsemi4N25SR2M can be used with both AC and DC signals as it can transmit both types of signals across the isolation barrier.
