The MBR4045WTG is a rectifier array part manufactured by ON Semiconductor. It is comprised of four independent 45V Schottky barrier diodes (SBD) connected in a standard array configuration. The MBR4045WTG is an ideal choice for use in low voltage, low power DC/DC converters, secondary power supplies, and general rectifier and freewheeling applications. The device is available in a Lead-free, RoHS compliant and compatible, SOD-323 surface-mount package, which offers device-on-board and board-to-board mounting capability. The package provides both solution cost savings and improved thermal and electrical performance. The MBR4045WTG’s low forward voltage drop, low reverse leakage current and high surge current capabilities are attained through the use of low thermal resistance Schottky barrier process material and low profile packaging technology. This makes the device perfect for high frequency power supplies. The MBR4045WTG is built in a hermetically sealed package for superior reliability and long term operation in various harsh operating environments. This device features a low forward leakage current, low reverse leakage current, fast recovery time and low capacitance between terminals. The MBR4045WTG has a wide operating temperature range of -55ºC to 125ºC and can handle up to 35A of peak current. It features a fast response to transient changes in the input voltage and is designed for use in applications involving a wide range of input voltages. The MBR4045WTG’s working principle is based on the effect of reverse biasing a junction, which creates a reverse electric field. The electric field reduces the amount of current which can flow, which in turn results in less power lost across the junction. It works in combination with a diode, which works with the input voltage to regulate the voltage levels. The MBR4045WTG is applicable to a diverse range of potential applications. Its suitable areas of use include off-line and DC-DC Converters in switch mode power supplies, SCR and TRIAC circuits, reverse polarity protection, transient voltage suppression and general rectification and freewheeling operations. Additionally, it is compatible with a variety of circuit designs which require fast switching and excellent surge protection, such as solar array electronic converters and automotive switch mode power supplies. The MBR4045WTG is an ideal solution for power supply designers looking for a simple and effective way to improve the performance of their DC/DC converters. With its low profile package, fast response to transient changes and wide operating temperature range, the part is an excellent choice for designers who need fast and reliable switching across a variety of electronic applications.
