Diodes - Rectifiers - Single

VS-10BQ040PBF is a balanced dual low forward voltage Schottky barrier rectifier with an I-V Curve feature and an integrated metal material. It is a Schottky diode typically used in automotive systems, communications equipment, industrial equipment, and instrumentation. The forward voltage has a low temperature coefficient and a low reverse leakage current. The device consists of two high-voltage junction rectifiers which are sealed in a metal-clad plastic package. This package offers superior thermal and electrical performance, high reliability, and a maximum operating temperature of up to 175°C. It is designed for use in applications requiring high power dissipation and/or high temperature operation.

Application Field

VS-10BQ040PBF is ideal for automotive, communications and industrial applications, including: DC-DC converters, uninterruptible power supplies, motor control systems, and battery-driven applications. It can also be used in lighting systems, fuel cells, solar applications, and other power management products. The low reverse leakage current eliminates the need for additional protection circuitry and allows for more reliable operation.

Working Principle

VS-10BQ040PBF works based on the principle of diode action. The diode is essentially a one-way valve for electrical current, allowing current to flow in one direction only. The diode is made of an anode and a cathode. When the voltage applied to the cathode is greater than the voltage applied to the anode, current will flow from the anode to the cathode, i.e. from negative to positive. However, if the voltage applied to the cathode is less than the voltage applied to the anode, the current will not flow, i.e. it will not pass the diode. The Schottky diode incorporates a special type of “junction” between the anode and the cathode, which makes it easier for current to pass through between the anode and the cathode. This is called a Schottky barrier, and allows the diode to operate at lower voltage and higher current levels than a standard diode.

The VS-10BQ040PBF is designed specifically to meet the needs of automotive applications, with its low forward voltage, low temperature coefficient, and low reverse leakage current. The Schottky barrier also allows for a low forward voltage drop, allowing for more efficient operation.

In conclusion, the VS-10BQ040PBF is an ideal rectifier for automotive, communications and industrial applications, with low forward voltage and low temperature coefficient for efficient operation. The low reverse leakage current eliminates the need for additional protection circuitry and allows for more reliable operation.
