MAPLAD18KP12CAE3

A TVS – Diodes, or Transient Voltage Suppressors, is an electrostatic protection device designed for single line and low inductance applications. It provides the most reliable device for electrostatic protection available on the market today. The MAPLAD18KP12CAE3 is a general purpose TVS – Diodes featuring a dual coplanar common anode and several integrated functions, such as overvoltage protection, compatibility with common ESD standards and EMI (electromagnetic interference) attenuation. It is designed to provide a low-inductance diode for transient current limiting applications.

These TVS – Diodes offer maximum effectiveness, feature an ultra-low on-state voltage drop, wide operating temperature range and are Hermetically sealed. The MAPLAD18KP12CAE3 is a perfect device for high speed line protection, like non-telecom, industrial and domestic PLC Ethernet networks, and it is guaranteed for up to 18kV ESD and up to 12kV BVS. The anti-parallel diode architecture improved the efficiency during high energy transients and is ideal for applications with high sensitivity against ESD, such as computers, peripherals, and peripherals.

Due to its integrated features, it could be used in any kind of environment and conditions, from low-voltage home applications to mission-critical industrial or automotive. Besides providing a reliable protection against dangerous transients and electromagnetic compatibility, the MAPLAD18KP12CAE3 can also shield traces from each other which, in turn, could reduce the effects of common-mode voltage or current that can cause EMI. The device also supports a wide supply voltages from 1.8V to 5.5V.

The principle of operation of the MAPLAD18KP12CAE3 is simple and effective. In the steady state operation, the common anode of the device is connected to the protected line and has an input current flowing through it; the diode’s depletion layer acts as a voltage blocking element, preventing any high voltage transient from entering the protected line. When a transient appears on the protected line, the common anode of the device reduces the voltage of the stray current on the protected line thus preventing it from entering the high-speed section. This also prevents any damage to the protected line and the device.

The MAPLAD18KP12CAE3 is a general purpose TVS – Diodes with a dual coplanar common anode. It is versatile and effective enough to provide circuit protection from transients in a variety of applications. Its low on-state voltage drop and wide operating temperature range makes it suitable for industrial, automotive and telecommunications industries. High current ESD protection, compatibility with common ESD standards, and EMI (electromagnetic interference) attenuation also make the device one of the best choice available.
