Overview
The B345CE-13 is a single Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 3 A. The device utilizes an SMC (DO-214AB) package to facilitate efficient thermal management and compact circuit board layouts. Key electrical specifications include a maximum DC reverse leakage current of 0.30 mA at rated voltage and a low forward voltage drop of 0.50 V at 3 A. The component supports a non-repetitive peak forward surge current of 80 A and operates within a junction temperature range from -55 °C to +175 °C.
Feature Summary
- Schottky barrier technology ensures fast switching speeds and minimal power loss during conduction.
- Low forward voltage drop reduces overall system heat generation and improves energy efficiency.
- High surge current capability provides robust protection against transient overcurrent events.
- Plastic encapsulation meets UL flammability classification standards for safety compliance.
Applications
- DC-to-DC converter output rectification
- Free-wheeling diode in inductive load circuits
- Power supply input protection
- Reverse polarity protection in battery-powered devices
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm RoHS compliance status with the supplier prior to order placement. Check for any specific handling requirements related to moisture sensitivity levels defined in the datasheet. Ensure storage conditions align with manufacturer guidelines to maintain device integrity before assembly.
Selection Notes
Select this component when a 45 V rating and 3 A continuous current capacity are required in a surface-mount form factor. Consider the SMC package dimensions for PCB space constraints. Evaluate the forward voltage characteristics against system efficiency targets. Verify that the operating temperature range meets the environmental demands of the final application.
Part Context
This device belongs to the B3xxCE series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings while maintaining consistent current handling capabilities. These components are engineered for general-purpose rectification tasks where speed and efficiency are prioritized over high-voltage blocking capabilities.
Replacement Considerations
Direct substitutes may include other 45 V, 3 A Schottky rectifiers in the SMC package from different manufacturers. Ensure pinout compatibility and equivalent electrical parameters such as forward voltage and leakage current. Verify that alternative parts meet the same thermal and mechanical specifications for seamless integration.
