MBR0540-TP
MCC (Micro Commercial Components)
Diode 40 V 500mA Surface Mount SOD-123
Active
Overview
The MBR0540-TP is a surface-mount Schottky barrier rectifier housed in a compact SOD-123 package. It is designed for low-voltage, high-frequency rectification and freewheeling applications, supporting an average rectified current of 500mA and a maximum DC reverse voltage of 40V. Its low forward voltage drop and fast switching characteristics make it ideal for power-efficient circuit designs.
Why Choose This Part
This diode offers a high operating junction temperature of up to 150 degrees Celsius, ensuring reliability in thermally constrained environments. The SOD-123 package provides a small footprint for high-density PCB layouts while maintaining a low reverse leakage current of 200uA at 40V.
Applications
DC-DC Converters
Used as a catch diode in low-power buck converters to improve efficiency during the switching cycle.
Reverse Polarity Protection
Protects sensitive battery-powered electronics from damage caused by incorrect battery insertion.
Freewheeling Diode
Suppresses inductive voltage spikes in small relay drivers and solenoid control circuits.
Signal Clamping
Protects high-speed logic inputs from overvoltage transients in digital systems.
