SMBJ300E3/TR13

The SMBJ300E3/TR13 is a Transient Voltage Suppressor Diode (TVS) that is designed to protect electronic components from overvoltage and overcurrent conditions. It is a three-pin diode that is commonly used in automotive, industrial, military and consumer applications. The SMBJ300E3/TR13 is constructed from a combination of silicon planar diode and glass passivated junction technology, which allows it to have a very low differential resistance, a high surge capability, a low capacitance and a fast response time.

The SMBJ300E3/TR13 can be used in a variety of applications. In automotive applications, it can be used to protect ECUs, airbags, sensors and cameras from excessive voltages caused by lightning strikes or electrostatic discharge. It can also be used to protect electrical systems in airplanes and military vehicles from the same type of damage. In industrial applications, the SMBJ300E3/TR13 can be used to protect motors, drives, and other critical components from power surges and other electrical transients.

In terms of its working principle, the SMBJ300E3/TR13 acts like a switch that will turn on and off very quickly when it detects an overvoltage, overcurrent, or other electrical transients. When the overvoltage is detected, the diode will pass current through it, which will rapidly reduce the voltage and thereby “save” the components connected to it from destruction. The transition from the open to the closed state occurs very quickly and is typically completed within fractions of a microsecond. As soon as the condition has been cleared, the diode returns to its open state and the current will immediately stop passing through it.

Because of its fast response time, high surge capability, and low capacitance, as well as its ability to protect electronic components from electrical transients, the SMBJ300E3/TR13 is a highly reliable and effective device. It is used in many different applications and has become a trusted component in automotive, industrial, military, and consumer products around the world.
