The SMBJ26A-M3/5B is a part of the Transient Voltage Suppressor (TVS) diodes family. Its main function is to protect against transient events and possible overvoltage surges, on voltage levels ranging from 5.5 to 170V.

The working principle of the SMBJ26A-M3/5B is quite simple. Whenever an overvoltage transient event or surge occurs, it will activate and start conducting. Its integrated protection mechanism will then conduct a certain amount of current to the ground, thus suppressing the overvoltage transient. This helps to protect the power supply, data lines, and other sensitive ICs from damages due to overvoltage.

Basically, the main function of the SMBJ26A-M3/5B is to provide protection against overvoltage transients and surges. These type of transient events affect any type of electronic device, and the SMBJ26A-M3/5B makes a great partner to any power supply design and also in the protection of data lines.

The SMBJ26A-M3/5B has a broad array of application fields, ranging from power supply and charging systems, to automotive systems and computer applications. Its integrated protection mechanism helps to maintain a stable voltage level, and support requirements for power protection. This type of transient suppression diode also helps to extend the life of the device and protect it from possible damage caused by excessive current.

Another important aspect of the SMBJ26A-M3/5B is its impressive endurance levels. It can withstand surge events with amplitude up to 200 Amps, and voltages up to 0.8V. Its clamping levels are also quite impressive, reaching up to 270W.

Apart from its protection capabilities, the SMBJ26A-M3/5B also features a low power dissipation level, making it also a good choice for any design focused on energy efficiency. Its rugged construction allows for a wide operating temperature range of -55 to +175°C and also the capability to withstand mechanical shocks, vibrations, and extreme variations in temperature.

The SMBJ26A-M3/5B can be found in a wide variety of industry applications, ranging from power supplies to automotive systems. Its integrated protection mechanism makes it an excellent choice for any current overvoltage scenario, helping to maintain a stable voltage level and keep the device away from any damage.

Finally, the SMBJ26A-M3/5B features a robust design and has great performance levels once activated. It is a great choice for any sort of power supply or data line protection scenario, and its low power dissipation level and impressive endurance levels allows for a broad array of applications, ranging from consumer electronics to automotive systems.
