Diodes - Zener - SingleThe SMBJ5915A/TR13 is a single Zener diode from Diodes with a power dissipation of 2 W, a maximum reverse voltage of 13 V, and a nominal Zener voltage of 11.5 V. It is useful in a variety of applications, such as circuit protection, overvoltage protection, reverse polarity protection, and voltage regulation. Looking more closely at its working principle and application field, the SMBJ5915A/TR13 operates on a principle known as Zener breakdown. This phenomenon occurs when a reverse bias voltage is applied on the diode, temporarily increasing the electric field across the junction and causing a change in the bandgap of the semiconductor material which allows electrons to flow through the junction. This is known as the Zener breakdown phenomenon or avalanche breakdown. The reverse voltage applied on the diode must be greater than the specified Zener voltage for this phenomenon to occur.The SMBJ5915A/TR13 is used in several applications that require high-energy-dissipation capabilities such as in voltage regulation circuits, reverse polarity protection, overvoltage protection on electronic components, and circuit protection. The SMBJ5915A/TR13 diode can be used in circuits to protect against overvoltage events by limiting the voltage applied to the circuit, since the power dissipation is great. It can also provide overvoltage protection by clamping the voltage to a predefined set voltage, preventing the voltage from rising above a certain value. It is widely used in battery-powered applications due to its reverse breakdown voltage, which enables it to protect the devices from overvoltage when the battery voltage rises above its nominal value.Since it has long-term stability, low cost, and a low power rating, the SMBJ5915A/TR13 diode is also used for voltage regulation. It can be used in circuits that require voltage regulation such as LED drivers, LED lighting, battery-powered applications, automotive lighting, and process control. It can also be used in circuit protection and reverse voltage protection. In these applications, when the circuit is subjected to overvoltage or reverse voltage stress, the diode can clamp the voltage and prevent the circuit components from becoming damaged.The SMBJ5915A/TR13 can also be used in other applications such as in AC/DC converters, fly-back converters, DC/DC converters, linear power supplies, peak droop circuits, and high-voltage detection circuits. It has a wide range of applications ranging from automotive to industrial and beyond. Its low-current feature allows it to be used in low-current circuits, such as in static RAMs and other devices.Overall, the SMBJ5915A/TR13 is a very useful device that can be used in a variety of applications. With its high power dissipation, long-term stability, low cost, and low power rating, it can be used for voltage regulation, reverse polarity protection, overvoltage protection, and circuit protection. Its wide range of applications and its ability to be used in low-current circuits make it an especially versatile device.
