Introduction

The SBRT3U40P1Q-7 is a s ingle rectifier diode developed by STMicroelectronics. It is designed specifically for high performance applications. It features low forward voltage drop and low power dissipation. It is specifically used for reverse polarity protection, rectification of 0.4A current, and for switching applications.

Application Fields

The SBRT3U40P1Q-7 diode is typically used in high power switching applications where low voltage drop and low power dissipation are crucial requirements. It is used to provide reverse polarity protection, rectifying 0.4A current and switching applications. It has excellent surge current capability and is highly reliable. It is most commonly used in power supplies, AC-DC converters, computer peripheral circuits, automotive applications, low voltage converters, and circuit protection.

Working Principles

SBRT3U40P1Q-7 is a single rectifier diode composed of two kinds of sections. The first section is a p-type semiconductor body that has its N-type terminal connected to the anode of the diode. The second section is a n-type semiconductor body which has its P-type terminal connected to the cathode of the diode. When a current is applied to the device the p-type semiconductor forces the electrons to flow from the anode to the cathode. When the electrons reach the cathode it forms a depletion layer which restricts the current flowing through the diode. When there is no current flow it can be used as a switch device and can switch DC current. The forward voltage drop of the device is typically 0.3V and the power dissipation can be as low as 0.25W.

Packaging

The SBRT3U40P1Q-7 is available in a SOT23-3 packaging. This allows for high levels of integration, making it ideal for handheld devices and other portable applications. The device's small size allows it to be housed easily in tight spaces within the application.
