TVS stands for Transient Voltage Suppression. TVS diodes, or also known as Transil diodes, are transistors optimized to clamp off overvoltage surges, spikes, or electrical transients in a circuit. This protection device clamps excessive voltage and eliminates surges coming through an AC/DC power system. A 30KPA64A-B, part of this product family, is an Unidirectional TVS Diode Array.

The 30KPA64A-B from Littelfuse offers average power dissipation rating of 21 W per device, a low forwrad voltage drop, and a capability up to 150W of peak pulse power (10/1000us). It is composed of eight 600W unidirectional Transil components, this diode is suitable for high speed data line, Ethernet, DVI, and USB protection. It has a working voltage range from 5 to 30 VDC power supply and a Max Stand-off voltage of 24 VDC.

The 30KPA64A-B is designed to provide ESD protection. It has a clamping voltage at 8.7 V@2W, and a peak forward surge current of 6 A @ 8.3 ms. This diode array is capable of storage temperature range of -55 °C to 150 °C however, for applications where the environmental temperature may exceed 125 °C, derating curve must be followed to ensure the operation of this diode. Its breakover voltage is 2.1 V @250 mA which can also change in time.

This 30KPA64A-B diode array works on a principle known as Zener clamping, which is widely known and the often chosen method to provide ESD and lightning protection. This principle is based on allowing excess current to flow into one diode in the array and thus protecting the rest of the circuit from an ESD or transient spike. The array is made up of many individual diodes connected in parallel. As a result, when exposed to a transient surge, each diode individualy takes up the excess current but in a controlled way to ensure that other components or systems nearby are not damaged. Each diode in the array is thus able to provide overvoltage protection at a high speed, with minimal impact on the function of the system.

By taking advantage of Zener clamping or TVS diode, the 30KPA64A-B can protect many types of systems by eliminating electric transients or spike. This protection device is commonly used on systems such as surveillance systems, serial ports, power systems, fiber optics systems, and many more. Furthermore, due to its design with multiple diodes in the array, it ensures a diversion and uniform distribution of current between the elements.

The 30KPA64A-B is a perfect choice to provide protection against overvoltage and transient surges. It acts as a safety mechanism for delicate electronics, and at the same time, ensures a reliable performance in extreme conditions. With it, one can be confident that their electronics will be safe from transient spikes or ESD occurrences.
