Overview
The Vishay 4N27-X007 is a single-channel phototransistor output optocoupler housed in a 6-SMD gull-wing package. It provides 5000 Vrms isolation voltage with an NPN phototransistor output capable of 100 mA collector current and 70 V collector-emitter voltage. The device features a minimum current transfer ratio of 30% at 10 mA forward current, with a maximum DC forward current of 60 mA and typical forward voltage of 1.5 V. Operating temperature ranges from -55°C to +100°C, with saturation voltage max 500 mV and power dissipation of 150 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Features a base terminal on the phototransistor for improved switching speed control
- Designed for surface-mount assembly in compact electronic systems
Applications
- Signal isolation in industrial control systems
- Interface between microcontrollers and high-voltage loads
- Power supply feedback loops
Procurement Notes
Verify the exact suffix against the manufacturer datasheet, as packaging options such as tape-and-reel or cut tape may affect availability. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the ordering part number matches the specific variant required for your design constraints.
Selection Notes
Select this component when a standard CTR range around 30% is sufficient for the application. Consider the 6-SMD package footprint during PCB layout. Verify that the 100 mA output current capability meets the load requirements. Check thermal management needs given the 150 mW power dissipation limit in enclosed environments.
Part Context
This part belongs to the Vishay 4N2x-X series of general-purpose optocouplers. It shares the same physical package and isolation rating as other members like the 4N25 and 4N26 but differs in current transfer ratio specifications. The series is widely used in legacy and modern designs requiring reliable galvanic isolation.
Replacement Considerations
Direct substitutes include the 4N25-X007T and 4N26-X007T if lower CTR is acceptable. For higher CTR requirements, consider the 4N35-X007T. Verify pinout compatibility and thermal characteristics before substitution.
