SMBJ180AE3/TR13

TVS-diodes, or transil-diodes, are a kind of over-voltage protection device mainly used to protect dual power supply circuits and equipment from over-voltage caused by lightning or other environmental interference. SMBJ180AE3/TR13 is a surface mount diodes with over-voltage protection, developed by the global semiconductor company Diodes Inc. This diode is rated for a maximum stand-off voltage of 180V, with a single peak pulse power dissipation of 1.5KW.

SMBJ180AE3/TR13 can be used in several different application fields due to its over-voltage protection capability. Firstly, it is used in automotive auxiliary power steering circuits, as it provides robust protection from high-voltage transients. Secondly, it can also be used in the peripheral circuits of industrial electronic equipment, for surge protection against powerful surges caused by changes in the power grid or switch contacts, and even atmospheric events. Finally, it can be used in medical equipment and appliances that are sensitive to voltage transients, as it ensures their reliability and long-term performance.

The working principle of the SMBJ180AE3/TR13 involves the use of a protective silicon diode. When an over-voltage occurs, the diode immediately reacts and begins to conduct current to protect the circuit. The diode allows current to flow in only one direction, effectively "clamping" the voltage so that it doesn\'t exceed its rated value. The diode dissipates the excess energy as heat, ensuring that the device is not damaged by the over-voltage.

SMBJ180AE3/TR13 is an important component in protecting sensitive electrical equipment from over-voltage damage. With its ability to dissipate high levels of energy, it can provide reliable protection against a wide range of environmental conditions. It is also easy to install, since it only requires an adjacent ground path to operate. All of these features make it a great choice for a variety of different application fields, and make it an excellent choice for protecting dual power supply circuits and equipment.
