TVS - Thyristors (Transient Voltage Suppressors) are a type of active semiconductor component typically used to protect against harsh electrical environments, such as those presented by lightning, industrial noise, and faults in power distribution systems. The P3406UBLRP is a family of TVS Thyristors manufactured by Tyco Electronics, which combine high Clamping Voltage (VLC) with low maximum clamping current (Ipp).

The P3406UBLRP is a unique type of TVS Thyristor that features a flat current-voltage curve and has a low leakage current in the low current region. This makes it ideal for applications where very low capacitance and extremely high peak current ratings are required.

The P3406UBLRP is suited for use in a wide range of applications, such as industrial, automotive, consumer, and telecom, and for both data and high-voltage power lines. It is particularly well suited for protection in high frequency AC/DC power supplies and for protecting high-speed serial data lines. The device can also be used on power cables, power sockets, and other high-voltage systems.

The P3406UBLRP working principle is based on the PNPN structure. When applied voltage rises above the Peak Pulse Voltage (Vpp) of the device, a current is generated in the PN junction that causes the Switching Voltage (Vsw) to increase. At Vsw, the device begins to conduct current, clamping the voltage to the specified value. As current flows through the device, it generates a voltage across the device which further reduces the voltage across it.

When the voltage drops back below the Break Over Voltage (Vbo) of the device, the current starts to drop and the device conducts less and less current, until the current is eventually cut off. The current is then cut off and the device returns to its non-conducting state. This process is repeated during the entire transient event, and the device prevents any further increase in voltage.

The P3406UBLRP is designed to withstand high peak-pulses of up to 8.6kV, making it suitable for use in high-voltage systems. It has a very low Clamping Voltage Rating (VLC) of less than 2.4V, which reduces power dissipation and improves system reliability. It also features a very low Reverse Leakage Current (ILR) of just 0.001mA, which reduces the risk of static electricity damage.

Overall, the P3406UBLRP is an ideal solution for design engineers looking for protection of their designs against surges, spikes, and other electrical transients. With its high peak-pulse rating and low Clamping Voltage Rating, it provides reliable protection for a wide range of applications.
