The STTH112UFY is a single rectifier diode designed by STMicroelectronics. It is a high-efficiency semiconductor device used mainly in high-speed and high-temperature switching power supplies. The STTH112UFY features self-adjusting high recovery speed, optimized for fast switching applications. It also offers excellent thermal stability, and the design of this diode ensures that it operates at high current levels and is able to withstand up to 10 million switching cycles before failure. This makes it ideal for use in applications where reliability and performance are critical.

The STTH112UFY is made from high-quality silicon and features a Hermetically sealed, flat surface that helps to minimize risk of short circuits and improve heat dissipation. The internal structure is designed to optimize heat transfer, ensuring efficient heat management and reliable operation. The design also allows for an adjustable peak current limit, which can be adjusted depending on the application’s power requirements.

The diode operates at reverse blocking voltages up to 600V, and the maximum reverse leakage current is 10mA. It has a maximum average forward current (I2t) of 25A, and the peak pulse current maintained over a 10ms pulse duration is 75A. The forward voltage drop is 1V at 25A, and the typical junction capacitance is 60pF. The on-state resistance is 0.2 ohms at 25A.

The process of rectification is a process used to convert AC current from an AC power source into DC current for a load. When the AC voltage is applied to a diode, it is almost completely blocked in its reverse-bias operation. When a current passes through the diode, it passes through its leakage resistance, and is effectively short-circuited. A rectifier diode is biased such that the reverse voltage bias exceeds the voltage of the AC input. This makes the diode to act as an electronic switch, allowing AC current to pass through the diode in one direction while blocking current flow in the opposite direction.

The STTH112UFY is suited for high-temperature switching power supplies, automotive power supply systems, LED lighting systems, and high-power AC-to-DC applications. Its high efficiency, low thermal resistance, and low forward voltage drop allows for increased power levels compared to traditional Schottky diodes and less power dissipation in high current AC-to-DC power supplies. In LED lighting systems, the STTH112UFY can enable higher efficiency operation and low heat gain, which helps reduce cooling requirements.

STMicroelectronics has designed the STTH112UFY with a robust internal structure and optimized performance parameters, making it a suitable choice for a wide range of applications. Its ability to handle large current and temperatures makes it a reliable choice, especially in applications that require frequent switching. With the ability to adjust its peak current limit, it allows users to tailor the diode’s performance to their individual needs.
