Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact ordering specifications. Ensure compatibility with required RoHS standards and packaging formats such as reel or cut tape. Confirm that the component meets all necessary automotive qualification requirements for the intended application environment before finalizing procurement.
Selection Notes
Select this component when a 70 V rating and 1 A current capacity are required in a compact SMB package. Consider the low forward voltage for efficiency and the wide operating temperature range for harsh environments. Verify that the AEC-Q101 qualification aligns with automotive design specifications and that the package footprint matches the PCB layout constraints.
Part Context
This part belongs to the B170 series of high-voltage Schottky barrier rectifiers from Diodes Incorporated. The series offers various voltage ratings while maintaining consistent current handling and package styles. The B170B variant specifically targets applications needing 70 V blocking capability with standard surface-mount integration.
Replacement Considerations
Direct substitutes may include other 70 V, 1 A Schottky rectifiers in the SMB package. Verify pinout compatibility and thermal characteristics. Cross-reference with equivalent parts from other manufacturers ensuring identical electrical parameters and package dimensions.
