Procurement Notes
Verify the specific part number against the official Bourns datasheet to confirm electrical ratings and compliance status. Ensure that the intended application environment falls within the specified operating temperature range and does not exceed the maximum surge current limits. Confirm RoHS and halogen-free requirements align with project specifications before finalizing procurement.
Selection Notes
Select this component when high reverse voltage blocking capability is required alongside a standard SMB footprint. The 1000 V rating distinguishes it from lower voltage variants in the S2x series. Consider the thermal resistance characteristics and ensure adequate PCB copper area for heat dissipation during continuous operation.
Part Context
This component belongs to the CD214B-S2x series of rectifier chip diodes manufactured by Bourns Inc. The series offers various voltage ratings ranging from 200 V to 1000 V within the same physical package format. It is designed for general-purpose rectification in space-constrained electronic designs.
Replacement Considerations
Compatible substitutes include other SMB-packaged rectifiers rated for 1000 V and 2 A, such as the MBR20100CT or equivalent glass-passivated silicon rectifiers. Verify pinout compatibility and thermal performance metrics before substitution.
