TVS devices (or transorb diodes) are typically used in applications such as switches, power supplies, circuit interrupt systems, and any form of electrical circuits with high voltage transients. These devices can dissipate large amounts of energy in a short period of time, thus protecting these devices from electrostatic discharge (ESD) and other transients.ERZ-V14D271 is a varistor device, it is a two terminal, non-linear device primarily used in applications where voltage and current need to be protected from high voltage, current and ESD transients. This varistor device is a 14mm disc device, its breakdown voltage range is 17.4V to 24V and its maximum peak pulse current is 25A. These features make ERZ-V14D271 an ideal choice for applications where medium to low level ESD protection is required.The working principle of ERZ-V14D271 involves the use of a Zener diode and a metal-oxide varistor (MOV), forming a parallel combination. The MOV is essentially composed of a sintered metallized layer of ZnO, which is sandwiched between two metal electrodes. The Zener diode limits and maintains the voltage below its rated voltage while the MOVs act as a current limiter, due to its low impedance path at low levels of voltage.When an overvoltage occurs, the Zener diode enters the conduction region limiting the voltage to a certain level, usually set by the application. The MOVs then quickly dissipate the excess current, which helps protect the device or application from transients. At the same time, the MOV also provides surge protection when higher voltages are applied, capable of withstanding voltages up to its rated voltage limits.The ERZ-V14D271 is typically used in applications such as power management, consumer electronics, communications, automotive and industrial electronics. This device is also highly reliable and offers a wide range of features such as excellent thermal stability, very low thermal run-time, and low leakage current.In summary, the ERZ-V14D271 is a versatile and reliable two terminal device offering excellent ESD protection and voltage/current protection. With its various features, it can be used for a wide range of applications ranging from consumer electronics to industrial applications. Its combination of Zener diode and MOV makes it a great choice for applications requiring medium to low level ESD protection.
