Overview
The B340BE-13 is a Schottky rectifier manufactured by Diodes Incorporated, designed for surface mount applications. It features a single diode configuration housed in an SMB (DO-214AA) package. The device supports a maximum repetitive reverse voltage of 40 V and a continuous forward current of 3 A. Key electrical parameters include a typical forward voltage of 500 mV at rated current and a maximum reverse leakage current of 500 uA. It withstands a forward surge current of 100 A and operates within a junction temperature range of -55 °C to +125 °C.
Feature Summary
- Utilizes Schottky barrier technology to achieve low forward voltage drop and high efficiency.
- Features a molded plastic encapsulation with a UL94V-0 flame retardant rating.
- Includes guard ring chip structure for enhanced transient protection capabilities.
Applications
- DC-DC converters
- Power supply circuits
- Free-wheeling diodes
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering quantity matches the manufacturer's standard packaging requirements. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement.
Selection Notes
Select this component when a 3 A current rating and 40 V blocking voltage are required in a compact SMB footprint. Consider the low forward voltage characteristic for improved thermal performance in power conversion designs. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions. Compare alternative packages if board space constraints differ from the SMB dimensions.
Part Context
This component belongs to the B340 series of Schottky rectifiers from Diodes Incorporated. The series offers various package options including SMA, SMB, and SOD-123F to suit different power and space requirements. These devices are engineered for general-purpose rectification in consumer electronics and industrial equipment. The B340BE-13 specifically utilizes the SMB package for higher current handling compared to smaller surface mount variants.
Replacement Considerations
Compatible substitutes include the B340B-13-F and B340LA-13-F, which share similar electrical ratings but may differ in package style or specific forward voltage characteristics. Verify pinout compatibility and physical dimensions before substitution. Consult official replacement guides for confirmed equivalents.
