Overview
The B340AF-13 is a single Schottky barrier rectifier manufactured by Diodes Incorporated, rated for a peak repetitive reverse voltage of 40V and an average rectified output current of 3A. It utilizes the SMAF surface-mount package with a low-profile design. The device features a maximum forward voltage drop of 0.50V at 25°C and a maximum reverse leakage current of 0.20mA at 25°C. It supports a non-repetitive peak forward surge current of 80A and operates within a temperature range of -55°C to +150°C.
Feature Summary
- Guard ring die construction provides transient protection capabilities
- Low forward voltage drop improves efficiency and reduces heat generation
- Reduced high-temperature reverse leakage increases reliability against thermal runaway
- SMAF package is ideally suited for automated assembly processes
Applications
- Boost diodes in power conversion circuits
- Blocking diodes for isolation applications
- Recirculating diodes in inductive load management
Procurement Notes
Verify that the specific order matches the B340AF-13 designation to ensure correct voltage ratings. Confirm packaging requirements align with the standard 10,000-unit tape and reel configuration. Check for compliance with RoHS directives and halogen-free specifications if required by the manufacturing environment. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.
Selection Notes
Select this component when a low-profile SMAF package is required for space-constrained designs. Choose this part over standard SMA packages if reduced height is necessary for the application profile. Consider the thermal resistance characteristics for heat dissipation planning in enclosed environments. Verify that the 3A continuous current rating meets the peak operational demands of the circuit.
Part Context
This component belongs to the B340AF/B345AF series of surface mount Schottky barrier rectifiers. It shares the same physical SMAF footprint as other variants in the family but differs in reverse voltage ratings. The series is designed for general rectification tasks requiring high efficiency and stability under varying thermal conditions.
Replacement Considerations
Direct substitutes include the B345AF-13 for higher voltage tolerance within the same package. Other SMAF packaged Schottky rectifiers from different manufacturers may serve as alternatives if electrical parameters match or exceed the specified limits.
FAQ
What is the maximum operating junction temperature for the B340AF-13?
The maximum operating and storage temperature range extends up to +150°C.
How does the reverse leakage current change at elevated temperatures?
The maximum reverse leakage current increases significantly at +125°C compared to +25°C, though it remains within specified limits to prevent thermal runaway.
