An efficient and reliable solution to suppress ESD and high voltage overloads, MAPLAD18KP160A is widely used in various applications. This article will discuss the application field and working principles of MAPLAD18KP160A.Application FieldMAPLAD18KP160A is highly applicable in varied industrial settings. It is used in a wide range of applications and provide effective protection of signals and data lines. Examples of its usage include: • Personal computers and peripherals: MAPLAD18KP160A is effectively used to protect data lines in laptops, motherboards, USB, serial ports, and other peripherals. • Telecommunications equipment: It is especially suitable for telephone and network equipment to protect communication lines and equipments from voltage overloads and ESD surges. • Industrial systems: It can be used in robotics, automated controls, ADA (Audible Digital Audio) systems, and other industrial equipments. • Automotive systems: It serves as an effective overvoltage protection for automotive applications, such as ECU and infotainment systems.• Medical equipment: The diode provides reliable protection to medical equipment, such as ECG and EEG systems. • Consumer electronics devices: It is extensively used in audio/video equipment, such as CD/DVD players and digital cameras.Working PrincipleMAPLAD18KP160A works on the principle of voltage clamping with low capacitance bidirectional silicon TVS diodes. When an overvoltage or an ESD surge is applied, the TVS diode turns on and limits the voltage at a pre-determined level, thereby suppressing the surge. The device also prevents the voltage levels from rising above the maximum rating of data and signal lines. MAPLAD18KP160A features a multi-stage protection mechanism and a low junction capacitance of 9pF. It offers excellent ESD suppression, with 8kV contact and 15kV air discharge capability, and is capable of handling up to 18A surge currents. The device also has a self-restoring action and ensures high isolation voltage of 10kVrms. The diode has a low forward voltage drop of 0.8V for 100mA and excellent clamping performance. Its fairly high maximum peak pulse current rating (18A) and high peak pulse power (4.5kW) provides transient peak surges protection to data and signal lines. Moreover, its compact size and high-temperature stability makes it an ideal choice for a wide range of application scenarios.ConclusionIn conclusion, MAPLAD18KP160A is a low capacitance and high performance TVS diode, which provides excellent protection to data and signal lines. It is an excellent choice for personal computers and peripherals, telecommunications equipment, industrial systems, automotive systems, medical equipment, as well as consumer electronics devices. The device provides superior ESD suppression and an excellent clamping performance even at high surge currents. Its low junction capacitance, as well as its robustness and reliability make it the ideal choice for reliable data protection in a wide range of applications.
