It is rated for average rectified current of up to 15.0A for 1.0s and for 0.5s at 30.0A. Additionally, it offers a low initial forward voltage of just 0.45V for low voltage applications.The rectifier is housed in a small, TO-220F package, which makes it compact and ideal for high-density circuit layouts. The device has an operating temperature range of -55°C to +150°C, making it ideal for extreme temperature applications. The device is also RoHS and REACH compliant.The 25TQ015STR rectifier can be used in a variety of applications, such as AC-DC adapters and power supplies, DC/DC converters, switch-mode power supplies (SMPS), portable and battery-powered devices, computer motherboards, telecommunications equipment and light-emitting diode (LED) lighting.

Working Principle

A Schottky rectifier circuit is made up of two diodes connected in series to form a bridge. When an AC voltage is applied to the input of the circuit, current flows through one diode and then the other as the voltage alternates. This creates a DC voltage on the output of the circuit.As the AC input reaches a higher voltage than the DC output, the current starts to flow in the reverse direction. The Schottky diode\'s low forward voltage drop (VF) allows it to turn-on easily and quickly, resulting in high current throughput with low power dissipation and high surge current capabilities.The 25TQ015STR diode’s high current rating and low VF enable it to handle large amounts of current with reduced power losses, making it suitable for power applications such as DC/DC converters, AC adapters and power supplies.

Conclusion

The 25TQ015STR Schottky diode is a high-performance rectifier designed for applications requiring high efficiency and power handling capabilities, making it suitable for power applications where low voltage and high current are essential. It is designed to handle large amounts of current with reduced power losses and has a wide operating temperature range making it suitable for extreme temperature applications.
