The MBRS20H150CT RNG with Schottky Barrier Diodes (SBD) D2PAK RoHS manufactured by Taiwan Semiconductor is a surface-mount diodes used for rectification, which means they convert alternating current (AC) into direct current (DC). They have low forward voltage and fast switching speeds, which makes them ideal for power switching applications, such as DC-DC converters or power supplies. The diode is a RoHS-compliant, which compliant to environmental requirements for hazardous materials, meaning that no hazardous substances, such as lead, are used in the product. The package is a D2PAK, which is a flat package with a center tab for soldering. This package provides higher power dissipation and is preferred for higher power applications.
