Overview
The SFH6156-1T is a single-channel transistor-output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a GaAs infrared LED emitter coupled to a silicon planar phototransistor detector within a 4-SMD鸥翼 package. Key electrical parameters include a maximum collector-emitter voltage of 70V, a continuous output current of 50mA, and an isolation voltage of 5300Vrms. The device operates with a typical forward voltage of 1.25V and supports a maximum DC forward current of 60mA. Current transfer ratios range from 40% to 80% at 10mA input. Switching characteristics include typical rise/fall times of 2µs/2µs and turn-on/off times of 3µs/2.3µs. It functions reliably across a temperature range of -55°C to 100°C.
Feature Summary
- High isolation voltage capability of 5300Vrms for robust circuit separation
- Integrated GaAs infrared LED emitter paired with a silicon planar phototransistor
- Surface-mount 4-SMD鸥翼 packaging designed for automated assembly processes
- Wide operating temperature range supporting industrial environmental conditions
Applications
- Signal transmission between electrically isolated circuits
- General-purpose digital signal isolation in control systems
- Interface applications requiring high reliability and compact form factor
Procurement Notes
Verify the specific suffix designation against official Vishay documentation to confirm current transfer ratio binning and packaging configuration. Ensure compatibility with RoHS3 standards if required by project specifications. Cross-reference datasheet revision dates to validate parameter accuracy before finalizing component selection for production.
Selection Notes
Select this component when high isolation voltage and moderate switching speeds are required in a surface-mount format. Consider the 40-80% CTR range for logic interface design. Evaluate thermal management requirements given the 100°C maximum junction temperature limit. Confirm that the 70V output voltage rating meets the load requirements of the destination circuit.
Part Context
This part belongs to the SFH6156 series of high-reliability optocouplers. The series utilizes a standard 4-SMD鸥翼 footprint common to many industry-standard isolators. Vishay designs these devices for general-purpose isolation tasks where space constraints favor surface-mount technology over through-hole alternatives.
Replacement Considerations
Direct substitutes within the same family include SFH6156-2T, SFH6156-3T, and SFH6156-4T, which differ primarily in current transfer ratio specifications. Verify pinout compatibility and electrical ratings before substituting.
