Overview
The Vishay 4N28-X009 is a single-channel transistor output optocoupler featuring an NPN phototransistor. It utilizes a SMD/SMT installation style within a PDIP-6 Gull Wing package. The device provides an isolation voltage of 5300 Vrms and supports a maximum collector-emitter voltage of 70 V with a peak collector current of 100 mA. It operates within a temperature range of -55°C to +100°C, dissipating up to 150 mW. The forward current rating is 60 mA with a typical forward voltage of 1.5 V. The unit weight is 400 mg.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical coupling.
- Features a standard NPN phototransistor output for reliable signal transmission.
- Designed for surface-mount assembly to facilitate automated PCB integration.
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microprocessors and logic devices
- Power supply feedback loops requiring galvanic separation
Procurement Notes
Verify the specific suffix X009 against official Vishay documentation to confirm the exact reel configuration and manufacturing date code. Ensure the procurement specification matches the required PDIP-6 Gull Wing form factor. Confirm RoHS compliance status through the latest datasheet revision. Validate that the supplier source aligns with authorized distribution channels to guarantee component authenticity and traceability.
Selection Notes
Select this component when a surface-mount solution is required for applications demanding 5300 Vrms isolation. The 70 V collector-emitter voltage rating suits low-to-medium voltage switching tasks. Consider the 100 mA collector current capability for driving moderate loads. Compare against through-hole variants if board space constraints differ or if higher thermal dissipation paths are necessary for the specific application environment.
Part Context
This part belongs to the 4N2x-X series of transistor output optocouplers manufactured by Vishay Semiconductor Opto Division. The series is characterized by its use of gallium arsenide infrared LEDs coupled with silicon NPN phototransistors. The X-series designation typically indicates specific packaging or tape-and-reel configurations intended for high-volume surface-mount production lines.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and isolation voltage ratings before considering alternative generic optocouplers from other manufacturers.
