Diodes - Rectifiers - Single: STTH1210DI Application Field And Working Principle

Diodes, especially rectifiers-single, have a wide range of applications in today’s electronic circuit systems. Especially for power supply systems, most people prefer to use rectifiers-single. STTH1210DI is a typical rectifiers-single product of STMicroelectronics that has been widely used in power rectification, motor drive, and many other fields. In this article, we will discuss the application field and working principle of STTH1210DI in detail.

What Is STTH1210DI?

STTH1210DI is a power rectifier manufactured by STMicroelectronics. It is a Schottky barrier rectifier consisting of two silicon semiconductors and a metal-to-silicon p-n junction. It has a single phase, 10A full wave rectification, 120V voltage rating, and low voltage drop. These features make it suitable for various applications. Among them, the most popular application fields of STTH1210DI include power rectification, motor drive, and overvoltage protection.

Application Fields of STTH1210DI

Power Rectification: STTH1210DI is widely used in power rectification. It can effectively convert alternating current (AC) into direct current (DC) through rectification, which is essential for various power supplies. The efficiency of STTH1210DI is relatively high, making it suitable for high power applications.Motor Drive: STTH1210DI is also widely used in motor drive applications. The low voltage drop and high peak current density are beneficial to the regulation of the motor speed and current, effectively improving the efficiency and controllability of the motor.Overvoltage Protection: STTH1210DI is also suitable for overvoltage protection. By controlling the flow of current through the barier, it can ensure that the voltage within an electronic system does not exceed a predetermined level, protecting both the system and the connected components.

Working Principle of STTH1210DI

The working principle of STTH1210DI is relatively simple. When the applied voltage on the part exceeds the VF(turn-on voltage) value (usually 0.3V-0.7V) of the STTH1210DI, the barrier is activated and the electrons travel through.At the same time, a reverse bias is applied over the junction of the STTH1210DI, which increases the electrolyte resistance and blocks the flow of electrons. This effectively reduces the current flowing through the diode.At the moment of full wave rectification, the STTH1210DI functions as an analogous of a digital switch. When the applied voltage exceeds the diode\'s forward voltage, the diode turns "on" and can pass alternating current. When the applied voltage falls below the forward voltage, the diode turns "off" and can\'t pass current. As a result, a stable direct current is produced.

Conclusion

In conclusion, STTH1210DI is a typical rectifiers-single product of STMicroelectronics, which is widely used in power rectification, motor drive, and overvoltage protection. Its working principle is relatively simple and relies on a reverse bias over the p-n junction to control the flow of current. This well-design device has excellent performance and is highly valued by users.
