SMBJ4736A/TR13

The SMBJ4736A/TR13 is a single precision, surface mount, Zener diode with a wide range of applications. The device is available in both through-hole and surface-mount packages and has a single, low distortion Zener diode connected in a single package. This diode is designed for applications that require a low-distortion, high-stability voltage regulator.

The Zener diode is a voltage regulating diode. It is designed to operate in a so-called "Zener breakdown" mode, where the device start conducting if the applied voltage exceeds a certain threshold. The device behaves like a normal diode but the voltage across it is controlled by the Zener breakdown voltage, making it an ideal device for regulating the voltage in a circuit. The SMBJ4736A/TR13 is a single diode with a Zener breakdown voltage of 4.8 Volts.

The Zener diode has a wide range of applications, and can be used in many different circuits as a voltage regulator. The most common use is to protect devices, such as circuits or microcontrollers, from damage due to excessive voltage levels. Since the Zener diode has a precise breakdown voltage, it can be used to accurately regulate the voltage in a circuit. The SMBJ4736A/TR13 is often used in high precision applications such as telecoms, automotive electronics, and industrial control.

The SMBJ4736A/TR13 is also used in consumer electronics, such as mobile phones and laptops. It is used to protect components from too high voltage levels, for example USB ports, which typically operate at 5 Volts. The Zener diode helps ensure that the voltage does not exceed a certain level, preventing damage to the components. In addition, the device is also used in power supplies and switching power supplies, where the precise breakdown voltage of the device helps to regulate the output voltage, ensuring that the voltage output by the power supply remains constant.

The working principle of the SMBJ4736A/TR13 is based on a diode\'s "Zener breakdown" phenomenon. This occurs when the voltage across the diode exceeds its breakdown voltage, usually due to an increase in the current through it. When this happens, the electric field across the diode builds up, causing electrons to be ripped out of the atoms in the diode. These electrons are then accelerated towards the diode\'s anode, causing a rapid increase in current. This rapid current draw causes the voltage across the diode to drop to a predetermined level - the Zener breakdown voltage - and the excess current is then diverted away from the device.

In summary, the SMBJ4736A/TR13 is a single precision, surface mount, Zener diode with a wide range of applications. The device is available in both through-hole and surface-mount packages and has a single, low-distortion Zener diode connected in a single package. The device is used in many circuits as a voltage regulator and can also be used in consumer electronics, power supplies and switching power supplies. Its working principle is based on the diode\'s "Zener breakdown" phenomenon, which occurs when the voltage across the diode exceeds its breakdown voltage.
