B345AE-13

Overview

The B345AE-13 is a single Schottky barrier rectifier manufactured by Diodes Incorporated in the SMA (DO-214AC) surface-mount package. It features a peak repetitive reverse voltage of 45 V and an average rectified output current of 3 A. The maximum forward voltage drop is 0.50 V at 3 A, with a maximum reverse leakage current of 0.30 mA at 45 V. The device operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Low forward voltage drop for improved efficiency
• High-temperature reverse leakage stability
• Guard ring die construction for transient protection

Applications

• Boost diode circuits
• Blocking diode applications
• Recirculating diode configurations

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure correct voltage and current ratings. Confirm that the SMA package type matches the design requirements. Check for RoHS compliance and halogen-free status if environmental regulations apply to the final assembly.

Selection Notes

Select this component for general rectification where low power loss and high efficiency are required. Ensure the circuit design accommodates the 3 A average current rating and derating curves. Verify thermal management capabilities given the operating temperature limits and thermal resistance characteristics.

Part Context

This device belongs to the B320AE-B345AE series of 3.0A Schottky Barrier Rectifiers. It shares the same physical package and basic electrical structure as other variants in the series, differing primarily in the rated repetitive reverse voltage. The series is designed for automated assembly processes.

Replacement Considerations

Compatible substitutes include B320AE-13, B330AE-13, and B340AE-13 from the same manufacturer series. These parts share identical packaging and current ratings but offer different reverse voltage specifications.
