Overview
The B340LB-13-F is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface mount applications. It features a single diode configuration within an SMB (DO-214AA) package. The device supports a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 3 A. Key electrical parameters include a maximum forward voltage of 450 mV at 3 A and a maximum reverse current of 2 mA. It withstands a forward surge current of 70 A and operates within a temperature range of -55 C to +125 C.
Feature Summary
- Guard ring die construction provides protection against transient voltage events.
- Low forward voltage drop ensures high efficiency and reduced power loss during operation.
- Lead-free finish with matte tin terminals complies with RoHS standards and supports automated assembly processes.
Applications
- Free wheeling rectification in low voltage circuits
- Polarity protection for sensitive electronic loads
- High frequency inverters requiring fast switching characteristics
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact packaging and tape specifications. Ensure the component meets required environmental compliance standards for the target application. Cross-reference the full part number with authorized distributor catalogs to validate availability and authenticity before procurement.
Selection Notes
Select this component when a compact surface mount solution is required for 40 V, 3 A rectification tasks. The SMB package offers a balance between current handling capability and board space efficiency. Consider the low forward voltage characteristic for applications prioritizing thermal management and energy efficiency over higher voltage ratings.
Part Context
This component belongs to the B340LA/B series of Schottky rectifiers from Diodes Incorporated. It shares core electrical specifications with similar models but differs in physical packaging, utilizing the SMB form factor instead of SMA or other variants. This series is engineered for general-purpose rectification in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include B340LA-13-F and B340BQ-13-F, provided the package type and pinout compatibility are verified. Alternative packages may require PCB footprint modifications. Ensure any replacement maintains the 40 V rating and 3 A current capacity for equivalent performance.
