Diodes are semiconductor devices, made up of p-type and n-type silicon, which allow electricity to flow through them in only one direction. Diode types include standard, Schottky, Zener, small signal and light emitting diodes (LEDs). The SMAJ4745E3/TR13 is a single Zener diode, specifically designed to provide precise voltage regulation.Zener diodes are designed to precisely regulate voltage in a system. They are made up of a pn junction, just like a standard diode, but have a higher doping ratio. This helps create a larger electric field, allowing for precise regulation of the voltage applied to the diode. When the voltage across the diodes reaches the zener breakdown voltage, a tiny current starts to flow from the positively doped to the negatively doped side. This reverse breakdown current helps to stabilize the reverse voltage across the diode. As a result, Zener diodes are used in circuit applications where stable, precise voltage regulation is essential.The SMAJ4745E3/TR13 is a single Zener diode that is designed to provide precise voltage regulation. This diode has an average forward voltage drop of 0.43V, with a max forward current of 500mA. The Zener breakdown voltage of this diode is 4.7V, with a maximum reverse current of 1.0mA. The power rating is 500mW, with an operating temperature range of -55°C to 125°C. It is constructed of an ultra-thin glass passivated junction and is housed in a DO-213AA package.The SMAJ4745E3/TR13 is ideal for use in applications that require voltage regulation with a precise voltage setting. Common applications include power management and motor drive devices, low power digital circuits, and battery operated circuits.The working principle of the SMAJ4745E3/TR13 is based on its Zener breakdown voltage. When the voltage applied to the diode is below 4.7V, it behaves like a standard diode and current flows in one direction only. When the voltage reaches the Zener breakdown voltage, a tiny current starts to flow from the positively doped to the negatively doped side, causing the voltage across the diode to become stable and the current through it to remain constant. This reverse breakdown current helps to stabilize the reverse voltage across the diode, and provides precise voltage regulation.In conclusion, the SMAJ4745E3/TR13 is a single Zener diode that is designed to provide precise voltage regulation. It features an average forward voltage drop of 0.43V, with a Zener breakdown voltage of 4.7V. This diode is ideal for applications that require voltage regulation with a precise voltage setting, such as power management and motor drive devices, low power digital circuits and battery operated circuits. It is constructed of an ultra-thin glass passivated junction and is housed in a DO-213AA package.The specific data is subject to PDF, and the above content is for reference
