Hi Folks! Hope you’re well today. Happy to see you around. In this post today, I’ll detail the Introduction to SB5100.The SB5100 is a Schottky diode used in electrical circuits to avoid overvoltage. It is also known as a hot-carrier diode and comes with low forward drop voltage. It is capable of high surge current and is used in power management and automotive applications.You can go through the Introduction to 1n5822 and Introduction to 1n5821 that I have uploaded recently.Read this entire post till the end as I’ll walk you through the datasheet, pinout, features, and applications of this tiny component SB5100.
Introduction to SB5100
- The SB5100 is a Schottky diode, also known as a hot-carrier diode, mainly employed for extremely fast switching.
- Schottky diode and regular diode are two different components in terms of voltage needed to power up these devices.
- The Schottky diode requires only 0.3V out of 2V DC source voltage, leaving behind 1.7V to power the diode. While, on the other hand, a common diode requires only 0.7V, leaving behind 1.3V to power the diode device.
- Schottky diode is also called a hot-carrier diode since when the metal anode is combined with a semiconductor material, it results in the creation of a barrier. The reason Schottky devices are also called a hot-carrier diode.
- MOSFETs replace these Schottky diodes where less power dissipation is required.
Before you apply this component into your electrical project, it’s better to go through the datasheet of the component that details the characteristics of the device, helping you better evaluate the power ratings of the device.Click the link below if you want to download the datasheet of component SB5100.
The following figure shows the pinout diagram of SB5100.
- SB5100 is a two-pin device, these pins are also called terminals. Where one pin is the anode and the other pin is the cathode used for the external connection with the electronic circuit.
- The cathode pin is negative and is the area from where the current leaves the diode and the anode pin is positive and is the place from where the current enters the diode.
- The current moves from the anode terminal to the cathode terminal. The anode positive pin is composed of metal and the cathode negative pin is made of semiconductor material.
The following are the main features and absolute maximum ratings of SB5100.
- Comes with low forward drop voltage
- Capable of generating high current

- Repetitive reverse voltage Max. = 100 V
- Forward surge current Max. = 150 A
- Forward voltage Vf Max. = 850mV
- Diode case style = DO-201AD
- Forward current = 5 A
- Operating temperature = 150 C
SB5100 Schottky Diode Construction
- The SB5100 is a Schottky diode composed of metal and semiconductor material. The N-type semiconductor material is used in the construction of the Schottky diode. When n-type material is combined with metals like tungsten, molybdenum, platinum, chromium, it creates the Schottky diode.
- It is important to note that both p-type and n-type semiconductors can be employed along with the metal, but n-type materials are preferred over p-type materials since the later carries low forward drop voltage.
- This Schottky diode is a two-terminal device. These terminals are known as anode and cathode terminal. The anode is a positive side that is composed of metal material and the cathode side is negative that is made of semiconductor material.
- The forward drop voltage of the diode is directly related to the nature of semiconductor material and metal employed for the formation of a barrier. Low forward drop voltage results in the release of less energy as heat, making this diode suitable for the applications sensitive to efficiency.
These devices are also employed in the solar systems that keep the batteries from discharging in the absence of solar energy.
- Incorporated in stand-alone photovoltaic systems.
- Employed in high-frequency and low voltage inverters.
- Can be applied to control the electronic charge.
- Employed in freewheeling and logic circuits.
- Used in DC/DC converters and polarity protection applications.
- Used for signal detection and radio frequency applications.
- Employed in extremely fast switching applications.
- Used in sample-and-hold circuits.
