TVS (transient voltage suppression) diodes are widely used to protect sensitive equipment from voltage surges and other transient voltage events. The A5KP210A-G is one such device supported by the Littelfuse TVS Diode product family. It is a low-leakage, unidirectional diode that is optimized for bidirectional high speed telecom applications such as Ethernet, DSL and USB ports. This device is designed with a low capacitance and reverse working voltage of 200V, and is rated for an operating pulse current of 180A.

The A5KP210A-G is particularly applicable to data line protection, which is where transient voltage suppression devices are most often used. It is highly effective in locations prone to surge events, such as customer premises wiring. The device consists of two silicon diodes connected in series, which are uniquely combined to provide superior symmetrical clamping and overshoot protection for two pairs of signals.

In order to provide effective surge protection, the A5KP210A-G must be connected correctly. The device has two lines of anode and cathode connections, which must be connected across the positive and negative data lines of the protected circuit. This allows the device to act as a shunt, diverting away any undesirable voltages from the sensitive equipment. The device also works as a passive impedance, limiting the flow of surge currents.

The A5KP210A-G also offers fast response times, ensuring that it can clamp and dissipate transient voltages within nanoseconds. This ensures that the protected circuit is not damaged by any overvoltage situations. The device is also certified to IEC 61000-4-2 and is compliant with the IEC 61000-4-5 surge standard.

The low leakage characteristics of the A5KP210A-G also ensures that, even under normal operating conditions, the line of protection is constantly intact. This ensures that the protected circuit does not receive any unwanted voltages which could damage sensitive equipment. This makes it ideal for applications such as Ethernet and broadband communication.

In addition to providing high-level protection, the A5KP210A-G is also designed to be highly reliable, offering a long-term service life. The device also offers a wide range of surge protection options, allowing designers to choose the protection level best suited for their application.

The A5KP210A-G is a great choice for circuit protection applications and offers superior performance versus traditional TVS diode designs. It is cost-effective, reliable and easy to install, making it an ideal choice for surge protection requirements.
