STB15100TR application field and working principle

STB15100TR is a type of single-phase rectifier diode, widely used in switching power supply and other related electronic devices. A rectifier diode is an electronic component that is able to convert alternating current (AC) to direct current (DC). It conducts the current in one direction and blocks current in the opposite direction. Because of its efficiency and precision, rectifier diodes are widely used in power electronics.

Application field

STB15100TR rectifier diodes are widely used in electronic devices, including but not limiting to switching power supply, motor, inverter, speed control (ESC) display and UPS systems. Being a single junction diode, it can produce higher forward current than its double junction counterpart which is usually used in lower current applications.

Also, STB15100TR rectifiers are specifically designed for industrial, commercial and aviation purposes. Currently, there are two types of STB15100TR single-phase rectifier, one with static forward voltage of up to 1000V and another with static forward voltage of up to 1200V, which meet the requirement of most electronic device applications.

Working Principle

A single-phase rectifier diode usually utilizes the "forward conduction" principle to produce DC from AC. Forward conduction means that the diode will only conduct current in one direction and block current in the opposite direction.

The working principle of single-phase rectifier diode can be divided into two stages: forward bias and reverse bias. During the forward bias stage, when the signal voltage of the diode is higher than the static forward voltage, the diode will be forward biased and will start to conduct current from the signal source until the current value reaches its peak current value. During the reverse bias stage, when the signal voltage of the diode is lower than the static forward voltage, the diode will be reversed biased, and will block all the current. This is how a single-phase rectifier diode works.

Conclusion

STB15100TR is a type of single-phase rectifier diode, widely used in switching power supply and other industrial, commercial and aviation applications. It utilizes the "forward conduction" principle, forward biased when the signal voltage is higher than the static forward voltage and reverse biased when the signal voltage is lower than the static forward voltage, to convert alternate current (AC) to direct current (DC).
