Introduction
SS25HE3_A/H is a single rectifier diode that is used for power conversion applications. It has a superior reverse-recovery time due to its U-shaped features in its P-N structure and it is effective at switching frequencies up to 20 MHz. This diode can be used in switching power supplies, such as a buck converter, PFC converter, and more. Its rated operating temperature is from -40°C to +150°C. The SS25HE3_A/H has a maximum peak forward surge current of 8A and a device reverse recovery time (trr) of 4.5ns.
Application Field
The SS25HE3_A/H is mostly used in high frequency switching power supplies. It is mainly used in up to 150 watts of buck-converters, DC/DC converters, isolated converters, and PFC converters because of its high reverse-recovery time, fast switching speed of 20Mode, and its ability to operate over temperatures from -40°C to +150°C.
Buck converters are used to convert a high DC voltage to a lower DC voltage by using switching elements. This type of power supply is compatible with external MOSFETs that offer additional performance that are optimized for the target application. The SS25HE3_A/H rectifier diode offers a great advantage in these applications due to its fast switching speed of 20Mode and its low reverse recovery time.
Isolated converters are used to convert a wide range AC voltage to a lower DC voltage while isolating the input from the output. The SS25HE3_A/H rectifier diode is a great choice for these applications due to its higher breakdown voltage, low reverse recovery time, and good thermal performance.
In addition to these types of converters, the SS25HE3_A/H can also be used in automotive applications that require a high efficiency, low voltage drop, and fast switching speed.
Working Principle
The SS25HE3_A/H is a rectifier diode that is used for power conversion applications. It has a U-shaped PN structure in order to have a fast switching speed and a low reverse recovery time. It operates by using junction rectification, which is a diode-based process by which current flows in one direction only.
When a voltage is applied to the anode and cathode of the diode, a depletion region is created that prevents current flow in the reverse direction. This effect is known as reverse-bias or reverse breakdown. When a reverse bias is applied, no current flows in the silicon rectifier and the transistor is off, meaning that the output voltage will be at zero.
When a voltage is applied to the anode and cathode that exceeds the threshold breakdown voltage of the diode, the depletion region is removed and current flows from the anode to the cathode. This effect is known as forward-bias or forward breakdown. When this happens, the transistor is on, meaning that the output voltage will be at the same level as the input voltage.
The SS25HE3_A/H rectifier diode is ideal for high frequency applications due to its U-shaped features in its P-N junction, which allows for a fast switching speed and a low reverse recovery time. Its rated operating temperature is from -40°C to +150°C and it has a maximum peak forward surge current of 8A.
Conclusion
The SS25HE3_A/H is a single rectifier diode that is used for power conversion applications. It has a superior reverse-recovery time due to its U-shaped features in its P-N structure and it is effective at switching frequencies up to 20 MHz. This diode can be used in switching power supplies, such as a buck converter, PFC converter, and more. Its rated operating temperature is from -40°C to +150°C. The SS25HE3_A/H has a maximum peak forward surge current of 8A and a device reverse recovery time (trr) of 4.5ns.
The SS25HE3_A/H is ideal for applications that require a high efficiency, low voltage drop, and fast switching speed. It is mainly used in up to 150 watts of buck-converters, DC/DC converters, isolated converters, and PFC converters because of its high reverse-recovery time, fast switching speed of 20Mode, and its ability to operate over temperatures from -40°C to +150°C.
