• TVS - Diodes
• MAPLAD18KP26CA Application Field and Working Principle

TVS (Transient Voltage Suppressor) diodes are widely used components in electrical and electronic applications requiring surge protection. They provide protection against over-voltage transients generated by lightning, power line surges, as well as other sources such as electrostatic discharge and switching inductive loads. The MAPLAD18KP26CA is a typical example of a TVS diode, with its small size, wide range of peak and holding currents, and voltage protection up to 18 volts.The MAPLAD18KP26CA is designed for applications where surge protection is required and space is limited. It is typically used in compact consumer electronic devices such as remote controls, cordless phones, laptops, tablets, and mobile phones. The diode can also be used in low power automotive, industrial, and medical applications.The MAPLAD18KP26CA uses a shunt-diode configuration. Its roof-top structure allows it to provide high breakdown voltage, fast response time, and high reliability. It is rated for a maximum peak pulse power of around 8.5 watts. The diode can be used in both polar (AC) and unipolar (DC) applications.The operating voltage range of the MAPLAD18KP26CA is from 3.3V up to 18V (or up to 24V in AC). Its logic level static and peak operating currents are 0.2mA and 100mA respectively. Its holding current is 0.2mA and its peak current is 100mA, both well within industry standards. It also has a low VF (forward voltage drop) of less than 0.5V.When exposed to transients, the MAPLAD18KP26CA will quickly and effectively clamp the voltage surges, directing the excess energy into the diode’s junction capacitance and safely away from other components. Once the transient is over, the diode will return to its non-conductive state.The MAPLAD18KP26CA is used in modular systems such as those typically found in telecommunications and broadband applications. It is also suitable for use as a general-purpose, board-mounted ESD (electrostatic discharge) protection device and for low voltage protection in various electrical and electronic devices.In summary, the MAPLAD18KP26CA is a cost-effective, reliable, small-sized TVS diode. It provides unipolar and polar protection up to 18V (24V in AC) with fast response time and clamps transients quickly and effectively. Its wide range of operating currents, low VF, and industry-standard ratings make it suitable for a variety of applications, from consumer electronics to industrial and medical equipment.
