Overview
The onsemi 4N25VM is a single-channel DC input optocoupler featuring a phototransistor output with an accessible base terminal. It provides 4170Vrms isolation voltage and operates within a temperature range of -40°C to 100°C. Key electrical parameters include a maximum forward current of 60mA, typical rise/fall times of 2µs, and a minimum current transfer ratio of 20% at 10mA. The device is housed in a 6-pin DIP package suitable for through-hole mounting.
Feature Summary
- Integrated phototransistor output with exposed base pin for enhanced control and speed optimization
- High isolation capability rated at 4170Vrms for reliable signal transmission across potential differences
- Wide operating temperature range supporting industrial and commercial environmental conditions
Applications
- Power supply feedback circuits
- Digital logic input interfacing
- Microprocessor input isolation
Procurement Notes
Verify the specific suffix 'VM' corresponds to the tube packaging format as indicated by distributor listings. Confirm RoHS3 compliance status and UL certification details against the latest manufacturer datasheet before finalizing procurement specifications. Ensure the 6-DIP package dimensions match the target PCB layout requirements.
Selection Notes
Select this component when base access is required for the phototransistor to improve switching performance or allow external biasing. The 4170Vrms isolation rating makes it suitable for applications requiring robust galvanic separation between low-voltage control circuits and higher-voltage power stages.
Part Context
This part belongs to the 4N25 series of general-purpose optocouplers manufactured by onsemi. It shares functional similarities with other members of the family but is distinguished by its specific packaging and base-terminal configuration designed for versatile integration in digital and analog isolation tasks.
Replacement Considerations
Direct substitutes may include other 4N25 variants from different manufacturers, provided they meet the 4170Vrms isolation and 6-DIP package constraints. Verify pinout compatibility and electrical parameter equivalence before substitution.
