Overview
The Vishay 4N25-X000 is a single-channel transistor output optocoupler featuring an infrared LED and silicon NPN phototransistor. It provides 5000 Vrms isolation via double molding. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a collector current of 50 mA, and a minimum current transfer ratio (CTR) of 20% at 10 mA forward current. The device operates with a forward current up to 60 mA and has typical rise/fall times of 2 µs. It supports a wide operating temperature range from -55°C to +100°C.
Feature Summary
- Provides high-voltage isolation between input and output circuits
- Features a standard industry dual-in-line package configuration
- Includes a base connection on the phototransistor for improved switching performance
Applications
- Logic ground isolation
- Switch mode power supply feedback
- AC mains detection
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and packaging variations. Ensure the selected variant matches the required isolation voltage and CTR specifications for the target application. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component when high isolation voltage and standard DIP packaging are required. Consider the 2 µs switching speed for moderate frequency applications. Verify that the 50 mA collector current rating meets the load requirements. Check if the base terminal availability is necessary for circuit design optimization.
Part Context
This part belongs to the Vishay 4N2x series of single-channel phototransistor optocouplers. These devices utilize gallium arsenide infrared LEDs coupled with silicon NPN phototransistors. The series is designed for general-purpose isolation in industrial and consumer electronics, offering reliable performance under varying environmental conditions.
Replacement Considerations
Cross-reference with other 4N25 variants or equivalent single-channel transistor output optocouplers from other manufacturers. Ensure compatibility regarding pinout, isolation voltage ratings, and current transfer ratio specifications before substitution.
