Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives if required by the target application. Cross-reference the part number with official distributor catalogs to validate current production status and availability before finalizing procurement plans.
Selection Notes
Select this component when a low-cost, general-purpose Schottky rectifier is needed for 70 V applications. The 1 A current rating suits moderate power levels. Consider the SMA package size for space-constrained designs. Evaluate thermal management requirements based on the 150 °C maximum junction temperature limit and expected ambient conditions.
Part Context
This part belongs to the B170 series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings and current capabilities in standard surface-mount packages. The B170 variant specifically targets 70 V reverse voltage applications, providing a balance between blocking capability and low forward voltage drop for efficient power conversion.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching voltage, current, and package specifications. Verify pinout compatibility and thermal characteristics before replacing the original component in existing designs.
