SDM10M45SD-7 Discrete Semiconductor Products

Diodes - Rectifiers - Arrays

The SDM10M45SD-7 is a device belonging to the category of rectifier arrays. It is a silicon-based rectifier intended for use in applications such as protection against overvoltage, reverse current protection, as well as voltage equalization and clamping. It is available in a package size of 10mm x 45mm and can handle up to 10A in surge or repetitive current. This makes it a suitable choice for use with large power distribution systems.

A rectifier is a type of electrical device which converts alternating current (AC) to direct current (DC). The SDM10M45SD-7 is a diode array package containing 6 diodes arranged in a bridge rectifier topology. This enables it to provide full wave rectification, creating a DC output from either AC or pulsed input. It also has low reverse leakage current and high forward surge protection for added reliability and improved protection against overvoltage and reverse current.

In order to understand the working principle of the SDM10M45SD-7, it is necessary to understand the basic principles of operation of a bridge rectifier. A bridge rectifier is composed of 4 diodes, arranged in a bridge like configuration. The AC input is applied to one side of the bridge, while the other side of the bridge is connected to the load. As the input AC voltage alternates, the diodes alternately turn on and off, conducting current into the output either in the forward or reverse direction, depending on the polarity of the input. This effectively results in full-wave rectification of the input AC voltage, creating a steady DC output at the other side of the bridge.

The SDM10M45SD-7 contains 6 diodes, providing added protection and reliability. The diodes are connected in a parallel configuration and each diode can handle up to 10A in repetitive or surge current. The device also comes with a built-in transient voltage suppressor (TVS) with an ultra low capacitance body diode, which prevents surge pulses from reaching the load and causing potential damage.

The SDM10M45SD-7 is suitable for use in applications such as over-voltage protection, reverse current protection, end-of-line VCC protection, over-current protection, clamping and voltage equalization. It is also suitable for use in power distribution and motor control systems. The combination of low reverse leakage current, high forward surge protection and low capacitance body diode makes it an ideal choice for applications in harsh operating environments.

In conclusion, the SDM10M45SD-7 is a rectifier array package containing 6 diodes which are connected in a bridge rectifier topology. It is suitable for use in applications such as over-voltage protection, reverse current protection, over-current protection, voltage equalization and for use in power distribution and motor control systems. The device has low reverse leakage current and high forward surge protection, making it suitable for use in harsh operating environments.
