TVS - Diodes are a form of surge suppression devices that are used to protect electronic circuitry from damaging voltage spikes and surges. One such device is the 3KP30-B TVS diode. As with other TVS diodes, it offers superior protection from voltage spikes and surges that can seriously damage sensitive electronic components. Let us take a close look at the 3KP30-B TVS diode and its application field and working principle.

Application Field

The 3KP30-B is a unidirectional low-capacitance TVS diode, designed to protect vulnerable electronic circuits from hazardous high-voltage surges such as those typically caused by lightning. It is specially engineered to provide high-speed clamping for very fast risetime disturbs. It has a maximum peak pulse current rating of 30A, a breakdown voltage of 72V, and operating junction temperature range of -55°C~ 150°C.

This TVS diode is ideal for protecting sensitive electronic components from inrush current, over-voltage, electrostatic discharge (ESD), and transients in AC/DC power systems. It is also used to protect signal, data, and control lines in fields like industrial electronics, automotive, telecommunications, and networking.

Working Principle

In general terms, the 3KP30-B TVS diode works the same way as any other TVS diode. When an over-voltage surge passes through the diode, it allows the positive charge to pass through while blocking the negative charge. This prevents damage to the electronic components connected to the diode.

The 3KP30-B diode is designed to offer excellent protection even when high-speed transients are involved. Its low capacitance mechanism helps it to clamp the voltage very quickly, reducing the duration of the surge by a significant amount. This helps to protect sensitive electronic components from harm.

The 3KP30-B diode also offers superior ESD protection. It is designed to divert surge energy away from the protected components, dissipate it in the form of heat, and quickly reach the low capacitance turnaround point. This helps to protect vulnerable components from ESD-induced damage.

The 3KP30-B also offers superior surge performance due to its breakthrough silicon-oxide-nitride-oxide-silicon (SONOS) technology. This provides bipolar charge balance, fast clamping response, and a very wide protection window that can accommodate both small and large surges.

The 3KP30-B is designed to be a robust and reliable surge protection solution that offers superior protection against voltage spikes and surges. Its application field includes a variety of fields such as telecommunications, networking, automotive, and industrial electronics, and its working principle is simple yet effective.
