It is suitable for automotive, power supply, telecommunication, and aviation industries. In terms of specific uses, it is suitable for high-speed rectification, resonant damping, and energy control in these industries. Moreover, 90SQ040 may also be used in half-wave, full-wave, and forward converters.The 90SQ040 rectifier diode series has a low-voltage drop and a low forward voltage rise that makes it ideal for energy-efficient power supplies. It also has the ability to tolerate more overload than traditional Schottky rectifiers. Furthermore, the 90SQ040 has low reverse current characteristics and reverse recovery time, which makes it well-suited for high-speed switching applications.

Working Principle

The 90SQ040 rectifier diode is a single device that operates using a Schottky barrier principle. A Schottky diode is a device formed by depositing a thin metal film onto a semiconductor substrate. When an electrical current flows through the device, it creates a barrier on the semiconductor’s surface between the metal and the substrate.The rectifier diode’s barrier keeps charge from escaping the device, allowing current to only pass from the anode to the cathode. In the forward direction, the voltage across the diode drops by a small amount, making it suitable for rectifying power efficiently.In addition, the 90SQ040 has a low reverse leakage current, which allows the diode to maintain its low-voltage drop even in high reverse voltage applications. The device also features built-in temperature independent of protection, making it safe to use in high temperature environments.

Conclusion

The 90SQ040 rectifier diode series is a single device with a Schottky barrier principle that is suitable for a variety of applications. Its low forward voltage drop, reverse leakage current, and switching speed make it suitable for automotive, power supplies, telecommunication, and aviation uses. It also has mean-time-before-failure protection and a low-voltage drop that make it efficient for rectifying power.
