TVS - Varistors, MOVs are electronic components designed to protect sensitive circuits from voltage spikes, surges, and overloads. The B72220S2950K101 is a transient voltage suppressor (TVS) from ST Microelectronics that is designed to safeguard against short and long over-voltage events. It provides both AC and DC protection for a wide range of applications, from automotive to space crafts.

Application Field of B72220S2950K1000

Due to its high reliability and performance, the B72220S2950K1000 is ideal for a wide range of applications. It is primarily used in consumer electronics, solar infrastructure, automotive, and aerospace and defense applications. More specifically, it can be used in automotive brake systems, automotive airbags, driver assistance, body computing, high-end infotainment systems, engine control units, and fuel injection systems. In addition, the B72220S2950K101 can be used for LED lighting modules, high-speed telecommunications, and high-power switching applications.

Working Principle of B72220S2950K1000

The B72220S2950K1000 is a monolithically integrated TVS-diode that is capable of suppressing both line-to-ground and line-to-line transients. It is designed to be bidirectional with high power capability (210 W). It has a low capacitance of 20 pF, which enables it to provide protection for high-speed data lines. In addition, it offers a low clamping voltage of 25V (at 8A) and a low operating voltage of 6.7V.

The B72220S2950K1000 consists of two terminals--an R (or reverse) terminal and a P (or positive) terminal. The R terminal serves as a diode anode, while the P terminal serves as a diode cathode. Once voltage exceeds the specified breakdown voltage of the TVS, the current flows through the device and is clamped at a safe level. This reduces the stress on the components of the circuit, thus protecting it from voltage spikes, surges and overloads.

Moreover, the B72220S2950K1000 also has a low threshold level, which ensures deep handling of already started transients. This prevent further propagation of surges and offers maximum protection to electronic systems, even in severe environments. Additionally, it can also reduce the stress on downstream components, even at very low input test pulse rise times (1 ns).

In summary, the B72220S2950K1000 is an excellent choice for a wide range of applications that require over-voltage protection. Due to its high reliability and performance, it is ideal for automotive, aerospace, defense, and consumer electronics markets. It can also provide excellent protection against short and long over-voltage events with its low capacitance, low clamping voltage and low operating voltage.
