Hi Friends! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to SR5100.

The SR5100 is a Schottky diode used to generate extremely fast switching. It is also called a hot-carrier diode and is protected against overvoltage. It comes with a high surge current capability and low forward drop voltage. It contains a forward rectified current around 5 A and terminal resistance around 28 C/W. It is available in epitaxial construction with a peak reverse voltage of around 100 V.

You are most welcome to see the Introduction to 1n4744 and Introduction to 1n4742 that I have uploaded recently.

Read this post all the way through as I’ll detail the datasheet, pinout, features, and applications of this tiny component SR5100.

Keep reading.

Introduction to SR5100

• The SR5100 is a Schottky diode, also known as a hot-carrier diode, used to produce extremely fast switching.
• MOSFETs can be used in place of these Schottky diodes where we need less power dissipation.

• Schottky diode and regular diode are slightly different in terms of voltage needed to power up these diodes. The Schottky diode needs only 0.3V out of 2V DC source voltage, leaving behind 1.7V to power the diode. While a regular diode needs only 0.7V, leaving behind 1.3V to power the diode.

• Schottky diode is also called a hot-carrier diode since it forms a barrier in an unbiased condition where electrons carry low energy on the semiconductor material that results in the formation of a barrier. The reason Schottky diodes are also called a hot-carrier diode.

SR5100 Pinout

The following figure shows the pinout diagram of SR5100.

• SR5100 is made of two terminals that are mainly used for the external connection with the electronic circuit.
• These terminals are known as anode and cathode. The cathode is negative from where the current leaves the diode and the anode side is positive from where the current enters the diode.
• The current moves from the anode pin to the cathode pin. The anode side is composed of metal and the cathode terminal is made of semiconductor material.

SR5100 Features

The following are the main features and absolute maximum ratings of SR5100.

• Contains low forward drop voltage
• Capable of generating high current
• Comes with high surge current capability
• Available in epitaxial construction

• Comes with high reliability
• Peak reverse voltage Max. = 100 V
• DC blocking voltage Max. = 100 V
• Average forward rectified current Max. = 5 A
• Thermal resistance = 28 C/W
• DC reverse current Max = 0.5 mA
• Storage temperature range = -65 to 175 C

You can see this tiny component comes with low forward drop voltage and is capable of generating high current. It carries high reliability with both peak reverse voltage around and DC blocking voltage around 100 V. Thermal resistance is 28 C/W and DC reverse current is 0.5mA with a storage temperature range -65 to 175 C.

SR5100 Schottky Diode Construction

• The SR5100 Schottky diode is made of metal and semiconductor material. Though both n-type and p-type semiconductor materials can be used, n-type material is preferred over p-type since the later comes with low forward drop voltage.
• When n-type material is combined with the metal like molybdenum, platinum, chromium, and tungsten, it results in the making of Schottky diodes.
• In the Schottky diode, there are two terminals used for external connection with the circuit. These terminals are known as anode and cathode. The anode side is positive and is made of metal while the cathode side is negative and is made of semiconductor material. The current flows from the anode side to the cathode side. And anode is the terminal from where the current enters the diode and the cathode is the terminal from where it leaves the diode.

• The forward drop voltage of the diode is mainly dependent on the nature of metal and semiconductor material used for the formation of a barrier. Low forward drop voltage leads to less energy released as heat that makes this diode an ideal pick for the applications sensitive to efficiency.
• These diodes are incorporated in the solar systems that keep the batteries from discharging in the absence of solar heat coming from the sun.

SR5100 Applications

• Used in freewheeling and logic circuits.
• Used in stand-alone photovoltaic systems.
• Can be used to control the electronic charge.
• Used in high-frequency and low voltage inverters.
• Employed in sample-and-hold circuits.
• Used for signal detection and radio frequency applications.
• Employed in extremely fast switching applications.
• Employed in DC/DC converters and polarity protection applications.
