TVS-Diodes: UCLAMP1571P.TNT Application Field and Working Principle

TVS-Diodes are voltage-dependent semiconductor devices commonly used for surge protection and ESD protection. A TVS Diode is often composed of four semiconductor elements: an anti-parallel diode and clamping circuit with an integrated transient voltage suppressor (TVS). TVS-Diodes have become increasingly popular due to their low capacitance, low power consumption, high level of protection, wide Voltage range, low clamping voltage and low self-inductance.The UCLAMP1571P.TNT is an advanced TVS-Diode designed for ESD and surge suppression in applications such as interfaces, port protection, peripheral devices, sensors, and more. This device has a peak pulse power dissipation of 1.6kW at 8/20µs and can protect against present and future high power, high frequency transients, surges, ESD, and lightning induced events.

Features of the UCLAMP1571P.TNT

The UCLAMP1571P.TNT is a DC-balanced TVS Diode with several desirable features, including: * Low capacitance: 1.4pF* Low power consumption: 15mA off, 30mA on* Wide working Voltage range: to 16V* Low clamping voltage: 19.5V at 8/20µs* Low self-inductance: < 0.1nH

Applications of the UCLAMP1571P.TNT

The UCLAMP1571P.TNT can be used in many diverse applications such as interfaces, port protection, peripheral devices, sensors, and more. It is especially well suited for applications that require low capacitance and wide working voltage range. It can be used to provide protection to high-bandwidth communication lines, data and signal lines, displays, memory and logic circuits, and power conditioning systems. It is also ideal for applications such as telecom switching systems, instrumentation, consumer electronics, and medical devices.

Working Principles of the UCLAMP1571P.TNT

The UCLAMP1571P.TNT works by using a P-N junction diode to absorb the transient voltage or current from overvoltage and ESD events. This junction is usually formed between two metal-oxide-semiconductor (MOS) structures, or between the drain and source of a Field-Effect Transistor (FET).The diode then turns on when the voltage reaches a certain threshold (the clamping voltage). This causes the excess current to be distributed to the diode, where it is dissipated as heat. Since the junction has a low capacitance, it is less prone to noise interference and can provide lower voltage distortion. This makes the UCLAMP1571P.TNT ideal for low-noise, low-distortion applications. The TVS Diode itself is composed of four main components: the two metal-oxide-semiconductor (MOS) elements, the diode, and the clamping circuit. The two MOS elements form the basis of the diode, and the clamping circuit helps to disperse the excess current to the diode.In summary, the UCLAMP1571P.TNT is a powerful and efficient TVS-Diode with many desirable features, such as low capacitance, wide working voltage range, low clamping voltage, and low self-inductance. Its protection capabilities and applications make it an ideal choice for high-bandwidth communication lines, data and signal lines, displays, memory and logic circuits, and power conditioning systems.
