MAPLAD18KP13AE3 Application Field and Working Principle

MAPLAD18KP13AE3 is a kind of transient voltage suppression (TVS) diode which is available for a wide range of polarities and uniform breakdown voltage ratings from 18 to 250 Volts. It is designed to protect sensitive electronics circuits from high voltage transients caused by inductive switching such as relay and solenoid contact bounces, load dump, and electrostatic discharge (ESD), as well as lightning.

MAPLAD18KP13AE3 Application Field

MAPLAD18KP13AE3 mainly used in portable applications, such as I/O port of notebook computers, modems, set-top boxes, and other applications. In addition, MAPLAD18KP13AE3 is also widely in automotive, medical, telecom and consumer electronics. It can just provide the adequate surge clamping to the system during the transient moment and will clamp the voltage effectively. With the small size, it has the efficiency to help system with the low performance and gains.

MAPLAD18KP13AE3 Working Principle

MAPLAD18KP13AE3 is a special structure TVS diode which is widely used in automotive and consumer electronics. It can provide a highly efficient level of voltage shunting capability and it can absorb up to a certain current surge pulse depending on its breakdown voltage rating. During a voltage surge, the MAPLAD18KP13AE3 behaves like a zener diode, turning on in order to shunting away the overvoltage from the terminals connected to it. When the reverse voltage of the diode reaches the Breakdown Voltage (Vbr) of the diode, it will start to turn on. When the reverse voltage increases, the peak current that can be handled will increase accordingly till it reaches its maximum withstand current (I=Ipk). When the pulse width is applied, the harder the diode will conduct, creating a high current clamp with a low impedance current path across its two terminals. This phenomenon limits the voltage spike from the transient down to a safe level. When the same peak pulse voltage is applied to a schottky diode, a high impedance current path would be created across its two terminals, making it unable to provide the fast shunt away speed. Thus, TVS diodes are able to act faster and better protect the connected components from destructive voltage pulse.

Summary

MAPLAD18KP13AE3 is a kind of TVS diode, which is mainly used in portable, automotive, medical, telecom and consumer electronics applications. It is designed to protect sensitive electronics circuits from high voltage transients by clamping the voltage spike from the transient down to a safe level. During a voltage surge, the diode behaves like a Zener diode, turning on in order to shunting away the overvoltage from the terminals connected to it. With its small size and high performance, it can be widely used in various applications.
