Overview
The Vishay 4N26-X017T is a single-channel phototransistor output optocoupler featuring a surface-mount 6-SMD gull-wing package. It provides 5000Vrms isolation voltage with an NPN phototransistor output capable of 100mA collector current and 70V collector-emitter voltage. The device operates within a -55°C to +100°C temperature range, supports a maximum forward current of 60mA, and typically exhibits a forward voltage of 1.5V.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical transmission
- Features an NPN phototransistor output stage for digital signal switching
- Designed for surface-mount assembly in compact electronic systems
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic families
- Power supply feedback loops requiring electrical separation
Procurement Notes
Verify the specific suffix X017T against official Vishay documentation to confirm exact Current Transfer Ratio (CTR) binning and packaging configuration. Ensure compatibility with standard SMD reflow profiles and check for RoHS3 compliance status in the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when a standard 6-pin SMD form factor is required for space-constrained designs. Compare CTR requirements against application load conditions; verify that the 100mA output capability meets the sink current demands of the receiving circuitry without exceeding saturation limits under worst-case temperature conditions.
Part Context
This part belongs to the 4N2x-X series of Vishay optocouplers, which are industry-standard replacements for legacy DIP-6 devices. The X-series variants specifically adapt these functions to modern surface-mount manufacturing processes while maintaining the electrical characteristics of the original 4N26 family.
Replacement Considerations
Direct pin-compatible replacements include the 4N25-X017T and 4N27-X017T. Verify functional equivalence regarding CTR ranges and isolation ratings before substitution.
