Overview
The B345BE-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum average forward rectified current of 3.0A and a repetitive peak reverse voltage (Vrrm) of 45V. The device utilizes an SMB (DO-214AA) surface-mount package. Key electrical characteristics include a low forward voltage drop for improved efficiency and reduced high-temperature reverse leakage current. It is designed for general-purpose rectification applications requiring fast switching capabilities.
Feature Summary
- Low forward voltage drop for better efficiency and cooler operation
- Reduced high-temperature reverse leakage current
- Increased surge overload capability
Applications
- General purpose rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the complete part number including suffixes against official Diodes Incorporated documentation to ensure correct voltage rating and package type. Confirm RoHS compliance status and specific tape-and-reel specifications required for automated assembly processes before finalizing procurement orders.
Selection Notes
Select this component when a 45V reverse voltage rating and 3A continuous current capacity are required in an SMB package. Consider its low forward voltage characteristics for efficiency-critical designs. Ensure thermal management aligns with the device's junction temperature limits under expected load conditions.
Part Context
This component belongs to the B3xx series of Schottky rectifiers from Diodes Incorporated, which offers various voltage ratings and package options. The B345 variant specifically provides a 45V blocking capability, distinguishing it from lower or higher voltage counterparts within the same product family line.
Replacement Considerations
Check for direct pin-compatible substitutes such as other 45V 3A Schottky diodes in SMB packages from Diodes Incorporated or other manufacturers. Verify that alternative parts meet or exceed the original forward voltage and reverse leakage specifications.
