Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm the exact Current Transfer Ratio (CTR) binning, as variations exist within the SFH6156 series. Ensure the procurement documentation matches the required packaging format, such as tape and reel or cut tape, to align with assembly line specifications. Confirm RoHS compliance status through the latest product change notification documents provided by Vishay.
Selection Notes
Select this component when a single-channel optocoupler with high isolation voltage and moderate speed is required. The SFH6156-3T is appropriate for designs needing a CTR range of 100% to 200%. Consider the SMD-4 package constraints for PCB layout. Compare against other SFH6156 variants if different CTR bins or packaging options are needed for the specific application requirements.
Part Context
This component belongs to the SFH6156 family of transistor output optocouplers from Vishay. The family offers various CTR bins and packaging configurations to suit different design needs. The SFH6156-3T specifically denotes a version with defined performance characteristics within this broader product line, sharing common structural elements like the GaAs infrared diode and NPN phototransistor.
Replacement Considerations
Direct substitutes may include other SFH6156 variants with matching CTR ranges, such as SFH6156-3, provided the packaging difference is acceptable. Verify pinout compatibility and isolation voltage ratings before substitution.
