The SMBJ5361AE3/TR13 is a Zener diode widely used in different applications including circuit protection, voltage regulation and waveform clipping. Its major features include a maximum power dissipation of 500 mW, a minimum breakdown voltage of 5.6V and a maximum clamping voltage of 11.2V.

A Zener diode’s operation is based on a reverse breakdown mechanism that occurs when the applied voltage exceeds the Zener voltage. When the diode is forward biased, electrons flow over the junction and the diode behaves like an ideal diode. When the applied voltage exceeds the Zener voltage, the diode gives off free electrons over the junction and these free electrons fill the depletion layer. This process of electron generation creates a region of lower resistance and a potential barrier is formed from the space charge. This region of lower resistance is referred to as a Zener breakdown region. The generated current flows through the diode until the applied voltage is equal to the Zener voltage.

The SMBJ5361AE3/TR13 Zener diode is popularly used as a switching regulator in power supplies and in DC to DC converters. It is also used as a voltage regulator by connecting it across a load and across a power source to reduce the source voltage. This ensures a stable supply voltage to the load and minimizes changes in current draw. In addition, the diode is used to clip waveforms and as a circuit protection element. When connected between a power source and a load, the diode protects the load from high voltage and short-circuit conditions that may arise due to external events.

The SMBJ5361AE3/TR13 Zener diode is a single component that is commonly used in a variety of applications, due to its wide range of features. It is durable, reliable and cost-effective, making it a popular and sought after component.
