High Current Capability, Low 0.63V Forward Voltage, and Flexible TO-220AB & D2-PAK Packaging for Reliable Power Designs

Micro Commercial Components (MCC) introduces the MBR3045CTH and MBRB3045CTH, a family of high-performance 30A 45V Schottky Barrier Rectifiers designed for efficient and reliable power rectification across a wide range of applications. Available in both TO-220AB through-hole and D2-PAK surface-mount packages, the series offers designers greater flexibility to meet different PCB layouts and thermal management requirements.

Built on advanced Schottky Barrier Rectifier technology, these devices combine a low forward voltage drop of only 0.63V, fast switching performance with low junction capacitance (740pF), and high junction temperature capability up to 175°C. These characteristics help reduce conduction and switching losses while improving overall system efficiency, making the series ideal for switching power supplies, DC-DC converters, battery charging systems, industrial power supplies, and telecom equipment.
