The DSTF20100C is a diode-rectifier-array (DRA) which provides improved operating efficiencies in comparison to the rectifiers typically found in the market. It is designed primarily for use in electronic systems where low ripple current and low noise are required. It is typically used for high current applications such as mobile radio, power amplifiers, microwave signals and other power amplifiers that require high frequency and power conversion efficiency.

The DSTF20100C array is composed of a main rectifier, four Schottky diodes and two Schottky diodes connected in series. This arrangement allows for improved operation in terms of inductance, input impedance and power dissipation by reducing the majority of the current losses that occur when a single diode is used as the main rectifier. The Schottky diodes are also designed to reduce the capacitance of the circuits, reducing power dissipation and increasing the operating efficiency.

The DSTF20100C array is designed for use with a 0V input voltage and a 0.4V to 1.4V output voltage. It can operate in a wide temperature range from -40C to +125C and can handle reverse polarity. It is designed to function with a power input voltage up to 40V and can provide up to 10A of output current. The operating frequency of the array is typically 30kHz and the average power efficiency is typically greater than 85%.

The operating principle of the DSTF20100C array is based on the characteristics of the Schottky diodes. The array consists of two Schottky diodes connected in series, where the first diode has a larger minority-carrier lifetime than the second. This allows the current to pass through the series-connected Schottky diodes with the first diode presenting a potential barrier to the second. Thus, when the output voltage is reached, the current flow is terminated by the first diode and a lower-valued remnant of current is left for the second diode. This simplified operating principle gives the DSTF20100C array improved operating efficiency compared to typical rectifier arrays.

The DSTF20100C array is commonly used in mobile radio and other power electronic systems requiring high frequency, high power conversion efficiency and low ripple current. It offers the user a wide range of operating efficiency, high power dissipation and low noise operation. It is very robust in operation and reliable for use in a variety of applications due to its improved thermal stability, wide temperature range and reverse voltage tolerance.

The DSTF20100C is an excellent choice for applications requiring high frequency, high power conversion efficiency and low noise operations. The array is simple and straightforward to use, providing significant enhancements in operating efficiency compared to the traditional rectifier arrays while still offering excellent power dissipation and noise reduction. This makes the array a great choice for mobile radio and other power electronics applications that require increased performance in a very small footprint.
