Diodes - Rectifiers - Arrays

The SBLF1040CTHE3/45 is an array of three 45V Schottky barrier rectifiers designed for high frequency switching applications.It is designed for use in applications that require the conversion of alternating current (AC) to direct current (DC) power and it is also suitable for battery charging.

Application Field of SBLF1040CTHE3/45

The SBLF1040CTHE3/45 is widely used in switch mode power supplies, telecom and uninterruptible power supplies and automotive applications. It has a low thermal resistance and low forward voltage drop, making it a good choice for applications that require low power dissipation. It also has an adjustable reverse polarity capability and is RoHS compliant.

Working Principle of SBLF1040CTHE3/45

The SBLF1040CTHE3/45 is a Schottky barrier rectifier designed for high frequency switching applications. It converts AC to DC electrical power using the Schottky barrier effect. In this effect, a metal to semiconductor junction is formed between the metal contacts and the semiconductor material. The junction voltage, also called the forward voltage, is very low for this type of diode. This low forward voltage allows for low power dissipation that makes it a good choice for power conversion.

The SBLF1040CTHE3/45 is a three phase rectifier, meaning it can reverse the polarity of an electrical current. The three phases consist of positive, negative and neutral. The positive and negative phases are connected to the diodes and the neutral is used as a return path. When one phase is positive, the other two are negative. This allows for the current to be reversed as the current flows through the three diodes.

The low forward voltage and high frequency response of the SBLF1040CTHE3/45 allows for greater efficiency and power density than traditional rectifiers. It also offers adjustable reverse polarity protection and is suitable for applications ranging from industrial to automotive. Additionally, it is RoHS compliant.

Conclusion

The SBLF1040CTHE3/45 is an array of three 45V Schottky barrier rectifiers designed for high frequency switching applications. It is suitable for use in applications that require the conversion of AC to DC power, such as switch mode power supplies, telecom, uninterruptible power supplies and automotive applications. With its low thermal resistance and low forward voltage, low power dissipation and adjustable reverse polarity capability, it is an ideal choice for high frequency switching applications.
