Infineon BAS4002A RPP Bridge Rectifier Diode, SOT-143, 40V, 200mA

The Infineon BAS4002A RPP E6327 is a high-performance, 4-pin Bridge Rectifier Diode designed for efficient power conversion and reliable circuit protection. Engineered using a low forward voltage (VF) Schottky diode array, this component enables low-loss bridge rectification, making it ideal for applications where energy efficiency is a primary concern.

Its core functions include providing polarity independence and robust reverse polarity protection for sensitive electronic circuits. The diode offers a repetitive peak reverse voltage of 40V and can handle an average forward current of 200mA, with a maximum forward surge current capability of 2A. The exceptionally low forward voltage drop of just 790mV contributes significantly to reducing power losses and minimising heat generation within compact systems.

This surface-mount (SMD) component is housed in a space-saving SOT-143 package, making it perfect for modern, miniaturised PCB designs. It features fast switching characteristics, which are essential for high-frequency applications and for maintaining signal integrity. The device is rated for a maximum operating temperature of 150°C, ensuring stable performance in demanding environments.
