The SDURD1540CTTR is a general-purpose, wide voltage, low-dropout Shottky barrier array rectifier. It has a maximum input voltage of 17V, a maximum ripple current of 0.7A, and a power dissipation rating of 6W. The device is composed of two independent 4A, dual-sided Shottky diode rectifiers in an 8-pin SOIC package.

The SDURD1540CTTR is suitable for a number of applications including voltage converters, rectifiers, DC/DC converters, polarity protection, reverse-current protection, and reverse-span protection. The device can also be used for protection against power surges or overvoltages in automotive and industrial applications.

The SDURD1540CTTR is a low-voltage drop rectifier array composed of two independent Schottky barrier rectifiers. Each rectifier is a two-directional, dual-sided device consisting of a multiple parallel connection of Schottky Barrier diodes. The rectifiers are connected in a lacing pattern to reduce the conduction resistance. This design provides superior noise emissions and superior current handling performance.

The working principle of the SDURD1540CTTR is based on the Schottky barrier phenomena, which is formed at the junction of two materials of different work functions. The barrier prevents reverse current flow by forming a “potential barrier” at the junction, resulting in a low forward voltage drop (VF). The device reduces energy loss due to the low forward voltage drop and higher switching speed.

The SDURD1540CTTR is used for various applications where high current and low voltage are required, such as DC-DC converters, low dropout converters, forward and reverse-span protection, polarity protection and reverse-current protection. The device is also used in overvoltage protection circuits for automotive and industrial applications.

The SDURD1540CTTR is a versatile device that offers superior power and reliability combined with superior noise emission and current handling performance. It provides a cost-effective solution for a wide range of applications where space and power dissipation are critical considerations.
