Overview
The B340AXF-13 is a 3A surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It utilizes Trench Schottky technology to achieve low forward voltage and minimal leakage current. The device features a SMAF (DO-219AA) package, rated for a peak repetitive reverse voltage of 40V and an average rectified output current of 3A. Maximum forward voltage drop is specified at 0.50V at 3.0A and +25°C, while maximum reverse leakage current is 0.20mA at 40V and +25°C. It supports a junction temperature range from -55°C to +150°C.
Feature Summary
- Trench Schottky barrier technology provides low forward voltage drop and reduced power loss.
- Guard ring die construction ensures robust transient protection capabilities.
- Soft switching characteristics minimize electromagnetic interference during operation.
- Halogen-free and antimony-free 'Green' molding compound used in the SMAF package.
Applications
- Low-voltage high-frequency inverters
- DC-DC converters
- Free-wheeling diodes
- Reverse polarity protection circuits
Procurement Notes
Verify that the specific order matches the B340AXF-13 designation to ensure the SMAF package and Trench Schottky technology are present. Confirm compliance with RoHS directives and Halogen-free requirements if mandated by project specifications. Review the datasheet for thermal derating curves to ensure adequate heat dissipation within the operating temperature limits.
Selection Notes
Select this component when a compact SMAF footprint is required alongside high efficiency and fast switching speeds. The Trench Schottky architecture offers superior performance compared to standard planar devices regarding leakage current and forward voltage. Ensure the application voltage does not exceed the 40V rating and consider thermal resistance values for PCB layout optimization.
Part Context
This part belongs to the B340 series of surface mount Schottky rectifiers from Diodes Incorporated. It represents an evolution in small-form-factor rectification, utilizing advanced trench technology to enhance electrical performance within the SMAF case. The series is designed for modern electronics requiring high reliability and space-efficient solutions.
Replacement Considerations
Direct substitutes include other 3A 40V Schottky rectifiers in the SMAF package. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with similar Diodes Incorporated parts such as the B340A series, noting differences in package size and technology type.
FAQ
What is the maximum non-repetitive peak forward surge current?
The maximum non-repetitive peak forward surge current is 65A for a duration of 1ms on a single half sine-wave superimposed on the rated load.
How does the forward voltage drop change with temperature?
The forward voltage drop decreases as temperature increases; it is typically 0.45V at +25°C and drops to approximately 0.39V at +100°C under a 3.0A forward current.
