Overview
The B190-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications. It features a DC reverse voltage rating of 100 V and an average forward rectified current of 1 A. The device utilizes the SMB (DO-214AA) package to facilitate automated assembly processes. Key electrical characteristics include a low forward voltage drop and high surge current capability, making it suitable for power conversion circuits requiring efficient rectification with minimal power loss.
Feature Summary
- Schottky barrier technology ensures low forward voltage drop and high efficiency during operation.
- Guard ring die construction provides protection against transient voltage events.
- Designed for automated assembly with lead-free finish compliant with RoHS standards.
Applications
- Low voltage, high frequency inverters
- Free wheeling diode applications in power supplies
- Polarity protection circuits
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation, as variations such as B190B or B190BE may exist with identical core specifications but different packaging or testing criteria. Confirm that the component meets current environmental compliance requirements including RoHS and REACH regulations before integration into final designs.
Selection Notes
Select this component for designs requiring a 1 A rectification capability with a 100 V reverse voltage margin. The SMB package offers a compact footprint suitable for space-constrained PCB layouts. Ensure thermal management accounts for the forward voltage drop at maximum load conditions to maintain junction temperature within specified operational limits.
Part Context
This part belongs to the B1xx series of Schottky rectifiers from Diodes Incorporated, which are engineered for general-purpose power supply applications. The series emphasizes reliability and performance in low-voltage environments, leveraging advanced semiconductor manufacturing techniques to achieve consistent electrical characteristics across production batches.
Replacement Considerations
Direct substitutes include B190B-13 and B190BE-13 from Diodes Incorporated, which share identical electrical ratings and package dimensions. Cross-brand alternatives must match the 1 A current, 100 V voltage, and SMB package constraints to ensure mechanical and electrical compatibility.
