The SMBJ5361B/TR13 is a single zener diode offering high breakdown potential and relatively low temperature coefficient. It is also known as “TVS diodes” as it is used to avoid transients and surges on power lines and to help protect electronic devices and systems. This type of diode can also be used in low-noise applications such as audio or switching power supplies. The working principles of the SMBJ5361B/TR13 diode are similar to those of a conventional diode. When the potential is applied to the device, the electrons flow easily through the p–n junction; however, when the potential difference is in the reverse direction, the device blocks this flow. The voltage at which the current begins to flow through the diode is referred to as the “brownout” voltage, and the diode is typically specified in terms of this value.

The high breakdown voltage of the SMBJ5361B/TR13 makes it an ideal choice for use in high-voltage applications such as lightning protection, EMI/RFI filtering, transient voltage suppression, and automotive and industrial applications. The maximum peak working voltage of 600V, with an operating junction temperature(-65 to +150°C) makes it ideal for applications that are exposed to high temperatures or high voltage spikes. The low power loss, low reverse leakage current, and built-in ESD protection of the device make it suitable for use in low-dropout regulators, local power supply, and battery powered devices.

The SMBJ5361B/TR13 is widely used in wearable electronics, automotive systems, appliances, telecom equipment, computers, and other electronic products. The device is capable of detecting a minimum load current of 200kA (Ipk max) against a maximum leakage current of 1µA and can sustain a peak pulse power of 250W (Ipk max). Due to its resistance to moisture and solvent, the SMBJ5361B/TR13 is suitable for use in harsh environments such as industrial, automotive, and medical applications. Moreover, the device has a low insulation resistance and wide operating temperature range (-65°C to +150°C) making it suitable for use in low-noise applications.

The SMBJ5361B/TR13 has a number of applications. It is commonly used in switching power supplies, UPS systems, and other high-voltage electrical equipment. It is also used in automobiles to protect electronic control units, LED drivers, and power converters from transients and surges. Moreover, the device is suitable for use in audio circuits, high-mode EMI/RFI filtering, and as an ESD protection element.

The SMBJ5361B/TR13 works by diverting excess voltage away from a circuit or device and into the ground, thus providing protection against high-voltage transients, surges, or over-voltage. The device operates by providing a low voltage drop while still allowing a sufficient current to flow. This diode is also capable of dissipating a significant amount of energy during its operation, which makes it ideal for applications where protection from severe transients is needed.In conclusion, the SMBJ5361B/TR13 is a single zener diode offering high breakdown potential and relatively low temperature coefficient. It is an ideal choice for applications that require protection from high-voltage transients and surges, and its low power loss, low reverse leakage current, and built-in ESD protection make it suitable for use in a wide range of applications. In addition, the device has a wide operating temperature range and is low-noise, making it suitable for audio circuits, EMI/RFI filtering, and as an ESD protection element.
