Overview
The B3100BQ-13 is a Schottky Barrier Rectifier manufactured by Diodes Incorporated, designed for high-efficiency power conversion applications. It features a 100V repetitive peak reverse voltage and a 3A average forward rectified current rating. The device utilizes a low-profile DPAK (SOD-128FL) surface-mount package to facilitate automated assembly and compact board layouts. Key electrical characteristics include a maximum DC forward voltage drop of 0.55V at 3A and a low reverse leakage current of 5mA at rated voltage. These specifications ensure minimal power loss and thermal generation during operation.
Feature Summary
- Low forward voltage drop for enhanced energy efficiency
- Fast switching speed with low reverse recovery charge
- High surge current capability for robust performance
- Lead-free finish compliant with RoHS directives
Applications
- DC-DC converters in portable electronics
- Power supply output rectification
- Free-wheeling diodes in inductive load circuits
- Reverse polarity protection in battery-powered devices
Procurement Notes
Verify the complete part number including the suffix '-13' which indicates tape and reel packaging configuration. Confirm that the DPAK package variant matches your PCB footprint requirements. Ensure compliance with environmental regulations such as RoHS and REACH if applicable to your manufacturing region. Cross-reference datasheet revision dates to guarantee parameter consistency with your design specifications.
Selection Notes
Select this component when a balance between current handling capacity and low forward voltage drop is required in space-constrained designs. The DPAK package offers superior thermal dissipation compared to smaller SMD packages while maintaining a small footprint. Consider the 100V rating to ensure adequate margin against voltage transients in the target circuit application.
Part Context
This device belongs to Diodes Incorporated's B3xxxB series of Schottky rectifiers, optimized for general-purpose power management. The series provides various voltage and current combinations to suit diverse industrial and consumer electronic needs. The B3100BQ specifically targets applications requiring reliable rectification with minimal heat generation.
Replacement Considerations
Potential substitutes include equivalent 3A 100V Schottky diodes in DPAK packages from other manufacturers, provided pinout compatibility and thermal characteristics match. Verify that alternative parts meet or exceed the original forward voltage and reverse leakage specifications.
