Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce this part number. Confirm RoHS compliance status and packaging type (tape and reel or bulk) against your assembly requirements. Ensure the supplier provides traceability documentation matching the datasheet specifications for quality assurance purposes.

Single Diodes Selection Notes

Select this component for applications requiring robust 1000V blocking capability and 1.5A continuous current handling. The fast recovery characteristic makes it suitable for higher frequency switching environments compared to standard rectifiers. Verify thermal management needs based on the specified operating temperature range and forward voltage drop.

Single Diodes Part Context

This device belongs to the FR15 series of fast recovery rectifiers from SMC Diode Solutions. The series offers various voltage ratings ranging from 50V to 1000V while maintaining a consistent 1.5A current rating. The FR157 specifically addresses high-voltage requirements within this family, sharing common mechanical and thermal characteristics with its lower voltage counterparts.

Single Diodes Replacement Considerations

Compatible substitutes include FR157G from Good-Ark and Rectron Semiconductor, which share identical electrical parameters and DO-15 packaging. Other equivalents such as FR157 from Taiwan Semiconductor are also functionally interchangeable provided pinout and thermal limits match.
