STPSC15H12D

Introduction

According to its classification, the STPSC15H12D falls under the category of Diodes - Rectifiers - Single. This fast switching class of diode is designed to withstand high currents over a wide range of voltage. This section will covering its application field as well as its working principle.

Application Field

The STPSC15H12D is commonly used in soft starters and frequency converters in industrial applications with its capability of high switching efficiency and its reliability. It also provide an insulation between high levels of power and delicate components like ICs.

Applications may extend to:

• Automotive applications such as electronic controlled cambelt systems, mechatronics and fuel pumps.
• Solar inverters using switch mode power supplies.
• Used in electric drive applications.
• High power operating in a wide range of temperatures.

Working Principle

The STPSC15H12D utilizes a Schottky diode which has a lower threshold voltage than a PN-junction diode. As a result, when there is an electric current flowing into the anode and a voltage drop across the junction, a Schottky diode can turn on faster than a PN-junction diode which has the same electric current.

Additionally, when the electric current increases, the voltage drop across the junction will also increase. The increasing electric current allows the Schottky diode to draw in more current and serve as a short-circuited bridge between the anode and the cathode. This allows the device to operate at high electric currents and process faster operations

The STPSC15H12D also has a high switching speeds, meaning higher the switching speed, lesser losses during the switching process. With a low on-state voltage drop and low reverse recovery time, it provides higher efficiency while using fewer components.

Conclusion

The STPSC15H12D type of diode can be usually found in applications requiring high electric currents and high switching speeds. Their high power and thermal handling capability allows them to safely provide insulation between delicate components and high voltage applications. The Schottky diode\'s low threshold voltage, high current rating and fast switching efficiency makes it a desirable choice for high power applications.
