SMBJ17C Application Field and Working Principle TVS - DiodesThe SMBJ17C is a Transient Voltage Suppressor (TVS) - Diode designed to protect sensitive electronic circuits from voltage transients induced by lightning and other transient voltage events. It is also used as an enhanced ESD clamp.The SMBJ17C is part of Vishay Semiconductors\' portfolio of TVS - Diodes, shielding against surge events from lower voltages up to 17 volts. It is a Bi-Directional, low capacitance, 17 volt TVS - Diode, designed to protect sensitive electronic components. Its fast respose time makes it effective against both Lightning and ESD events.In order to understand how the SMBJ17C works it is important to have a brief understanding of how a Transient Voltage Suppressor works. A Transient Voltage Suppressor is a device that works by quickly diverting the excess electric current away from the circuit and towards the ground. The SMBJ17C works by rapidly changing your switches between a very conductive state (on) and a very non-conductive state (off) in order to effectively protect the circuit it is installed on.The main action of this device is to redirect long-term overshoot to the outside world. It has two basic parts: the zener diode, and a back-to-back diode. When a transient voltage event occurs, the zener diode begins to conduct. As it conducts, it allows the current to travel through to the other end of the diode, the back-to-back diode. This back-to-back diode helps absorb the transient away from the circuit, and safely \'shunts\' the excess current to ground.Thanks to the fast response time of the SMBJ17C, it can protect sensitive components from both lightning and ESD (electrostatic discharge) events. The SMBJ17C is an ideal protection device for computer and medical equipment, automotive, and industrial applications.The SMBJ17C series of TVS - Diodes offer both low capacitance and a low clamping voltage, making them an ideal solution for protecting data lines, and a wide variety of circuit applications. Thanks to their Bi-directional design, they can quickly protect both AC and DC circuits.In conclusion, the SMBJ17C is a low capacitance, 17V, Bi-directional, Transient Voltage Suppression - Diode, designed to protect a wide variety of sensitive electronic components from transient voltage events. It quickly redirects long-term overshoot away from the circuit and towards the ground thanks to its fast response time. The SMBJ17C is a perfect solution for circuit protection applications.
