Overview
The B140-13-F is a surface-mount Schottky barrier rectifier designed for low voltage, high-frequency inversion and freewheeling. It features a high current capacity of 1A in a standard SMA package, offering a low forward voltage drop of 500mV to maximize efficiency. Its construction provides high surge current capability and is suitable for high-speed switching applications.
Why Choose This Part
This diode offers a very low forward voltage drop of 0.5V at 1A, significantly reducing power loss compared to standard silicon rectifiers. The SMA package provides a low-profile surface mount footprint with high power dissipation capabilities, while the 40V reverse voltage rating supports a wide range of common 12V and 24V DC systems.
Applications
Polarity Protection
Used as a low-loss series diode to protect sensitive DC circuits against accidental battery reversal.
DC-DC Converters
Acts as a freewheeling or catch diode in switching power supplies and buck converters to provide a current path during inductor discharge.
Secondary Rectification
Ideal for high-frequency rectification in switch-mode power supplies (SMPS) and low-voltage AC adapters.
Battery Charging
Prevents reverse current flow from the battery back into the charging source when input power is removed.
