STPS20S100CFP Introduction

The STPS20S100CFP from STMicroelectronics is a surface-mount package of two Schottky barrier diodes, suited for application in commercial and consumer electronics. It uses gold-metallized contact regions, integrated onto a common substrate, for the Schottky barrier diodes. These diodes can be used for rectification, protection, or conditioning of signals in power supplies and DC-DC converters.

The STPS20S100CFP package is available in an SMD or surface-mount configuration. It measures 4 mm x 3 mm x 0.8 mm and weighs just 0.02g. The device comes in a 5-pin SOT-25 package with a maximum dissipation rating of 1W and a maximum load current of 0.5A.

STPS20S100CFP Application Field and Working Principle

Application Fields

The STPS20S100CFP Schottky barrier diodes are primarily used for rectification in power supplies or DC-DC converters. They are also used in automotive electronics, such as ignition and switching systems, as well as in industrial and consumer electronics products.

For automotive applications, the STPS20S100CFP is rated to survive load dump pulses up to 100V. It is also compliant with the AEC-Q101-002 automotive grade specifications.

Working Principle

Schottky diodes are a type of diode with a metal-semiconductor junction, instead of the typical p-n junction. When a forward bias is applied, current can flow through the Schottky barrier, allowing current to flow from the positive to the negative terminal of the diode. When a reverse bias is applied, the Schottky barrier prevents current from passing through, thus blocking currentflow.

In this way, Schottky diodes can act as rectifiers, allowing current to flow only in a single direction. They can also be used for protection, by preventing voltages from exceeding a certain level, as well as for conditioning signals. They are more efficient than regular p-n junction diodes and can handle high frequencies, due to their low capacitance values.

Benefits

The STPS20S100CFP package of two Schottky diodes offers several benefits over single diodes, such as improved reliability, lower power loss and better cooling. The package also has a maximum load current of 0.5A and a maximum dissipation rating of 1W, making it suitable for high-power applications.

It also has a low forward voltage drop of 0.3V, which contributes to its energy efficiency. The STPS20S100CFP is an ESD-protected device with a low leakage current, making it ideal for automotive applications. In addition, the package is RoHS compliant, making it an environmentally friendly option.
