Overview
The SFH6156-3X001T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70 V and a maximum collector current of 100 mA. The device provides an isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 60 mA, a typical forward voltage of 1.25 V, and a collector-emitter saturation voltage of 400 mV. The current transfer ratio ranges from 100% to 200% at a forward current of 10 mA. Switching characteristics include a rise time of 2 µs and a fall time of 2 µs.
Feature Summary
- High reliability phototransistor output suitable for demanding industrial environments
- Wide operating temperature range supporting extreme thermal conditions
- Surface mount SMD-4 package design for automated assembly integration
Applications
- Switch mode power supply feedback circuits
- Telecommunications signal isolation interfaces
- Battery powered equipment control systems
Procurement Notes
Verify the specific suffix X001T against official Vishay documentation to confirm the exact Current Transfer Ratio binning and packaging configuration. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding lead frame or assembly modifications before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and fast switching speeds are required in a compact surface mount footprint. Compare the 100-200% CTR specifications against circuit requirements to ensure adequate noise immunity. Evaluate thermal management needs given the wide operating temperature range and power dissipation limits.
Part Context
This part belongs to the SFH6156 series of high-speed optocouplers designed for general-purpose isolation applications. The series offers various CTR bins and packaging options to suit different design constraints while maintaining consistent electrical performance and safety certifications across the family.
Replacement Considerations
Direct substitutes include SFH6156-3T and SFH6156-3. Verify that alternative parts match the 5300 Vrms isolation rating and 4-SMD package dimensions to ensure mechanical fit without redesigning the PCB layout.
