Overview
The B350B-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMB (DO-214AA) package with two pins. The device supports a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 50 V. Key electrical parameters include a maximum forward voltage of 0.7 V at rated current, a non-repetitive peak forward surge current of 100 A, and a maximum reverse leakage current of 0.5 mA at the rated voltage. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Guard ring die construction provides protection against transient voltage variations.
- Designed for low power loss and high efficiency during rectification.
- Ideally suited for automated assembly processes on printed circuit boards.
Applications
- Free-wheeling diode applications in switching circuits
- Power supply rectification stages
- General purpose rectification in consumer electronics
Procurement Notes
Verify the specific suffix designation when ordering, as the provided model lacks the standard trailing character found in official documentation. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors prior to procurement. Ensure the package type matches the required PCB footprint specifications for the target design.
Selection Notes
Select this component for designs requiring a 3 A continuous current rating with a 50 V blocking capability. The SMB package offers a compact solution for space-constrained layouts. Consider the thermal management requirements associated with the 0.7 V forward voltage drop at full load to ensure reliable operation within the specified temperature limits.
Part Context
This part belongs to the B350 series of surface mount Schottky barrier rectifiers from Diodes Incorporated. The series includes variants with different reverse voltage ratings, such as B320 through B360, all sharing the same 3 A current handling capability and physical package dimensions for interchangeability in certain designs.
Replacement Considerations
Compatible substitutes include Vishay Semiconductors B350B-E3/5BT and other manufacturers' B350 equivalents. Verify that replacement parts maintain the same SMB package outline and electrical characteristics to ensure direct fitment without redesigning the PCB layout.
