Tvs diodes, sometimes referred to as transient voltage suppressors (TVS), are types of diodes used to protect electronic devices from transient voltage spikes. They are able to do this by conducting large currents, momentarily, to ground, to ensure that the electrical component they are protecting does not experience a damaging peak of voltages. This article will discuss the application fields of SMDA24CE3/TR13 and the working principle they employ to function.SMDA24CE3/TR13 are unidirectional Tvs diodes designed to protect sensitive components from voltage transients caused by electrostatic discharge (ESD) and overload events. These particular TVS diodes have an operating voltage of 24V, 6kV ESD rating, and a 3Ω maximum dynamic resistance. They are often found in applications which require efficient protection from overload voltages, such as power line protection and computer board protection.SMDA24CE3/TR13 are voltage dependent devices, which employ a special surge voltage rating system, established in accordance with their various electrical characteristics. This type of Tvs has a breakdown voltage of 24V and a clamping voltage of 30V. The breakdown voltage represents the voltage at which the diode begins to conduct current, and the clamping voltage represents the voltage at which the diode conducts its maximum current.The diode typically operates in a non-conductive state until a surge voltage is applied across it. When this surge voltage exceeds the diode\'s breakdown voltage, the diode will begin to conduct current. The diode will then continue to conduct current until the voltage reaches the clamping voltage, at which point it is conducting its maximum current. During overload events, the diode will begin to conduct current instantaneously and dissipate the energy of the surge voltage until the device is no longer conducting or has reached its maximum dissipation. This instantaneously acting characteristic of the diode is referred to as its \'clamping\' characteristic.In the case of an ESD event, SMDA24CE3/TR13 operate in a similar fashion. When the diode is exposed to a voltage surge which exceeds its breakdown voltage, the diode will begin to conduct and dissipate the energy of the surge until the voltage has been dissipated. ESD diodes are well suited for applications which demand extra protection from transient voltage, such as cell phones, computers, and other electronic devices.Aside from their uses in protecting from ESD and overload events, SMDA24CE3/TR13 also finds application in special circuit designs, such as EMI and RFI attenuators. These attenuators are typically designed to reduce or eliminate high frequency noise on audio signals or power supplies. The SMDA24CE3/TR13 TVS diode provides this protection by clamping any damaging transient voltages which exceed the diode\'s breakdown voltage.In summary, SMDA24CE3/TR13 are unidirectional Tvs diodes designed to protect sensitive components from transient voltage spikes. They are well suited for applications which require efficient protection from overload voltages, as well as EMI and RFI attenuation. The diode utilizes a breakdown voltage of 24V and a clamping voltage of 30V, to dissipate the energy of the pulse and protect the electrical component it is attached to.
