Overview
The onsemi 4N25FR2VM is a single-channel transistor output optocoupler housed in a PDIP-6 package. It features an NPN phototransistor output with a collector-emitter voltage of 70 V and a maximum forward current of 60 mA. The device provides high isolation capability with a breakdown voltage (Bvceo) of 7500 Vrms. Key electrical parameters include a typical rise time of 6 µs, fall time of 24 µs, and a power dissipation rating of 250 mW. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage isolation between input and output circuits
- Features an NPN phototransistor output for digital signal transmission
- Designed for through-hole mounting in standard DIP packages
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microprocessor-based circuits
- Switching power supply feedback loops
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions meet moisture sensitivity level standards to maintain device integrity upon installation.
Selection Notes
Select this component when high isolation voltage is required alongside standard transistor output characteristics. Consider the specific rise and fall times for signal integrity in switching applications. Verify that the PDIP-6 package fits the available PCB footprint and thermal management constraints of the design.
Part Context
This part belongs to the 4N25 series of optocouplers from onsemi, widely used for general-purpose isolation. The FR2 suffix typically indicates reel packaging, while VM may denote specific manufacturing or quality codes. It serves as a robust solution for isolating low-voltage control signals from higher-voltage loads in industrial environments.
Replacement Considerations
Direct substitutes include other 4N25 variants such as 4N25M or 4N25VM, provided pinout and electrical ratings match. Verify compatibility with existing circuit designs, particularly regarding isolation voltage and current transfer ratio specifications.
