TVS diodes, also known as Transient Voltage Suppression (TVS) Diodes, are components that are used to protect sensitive electronics from voltage transients. The TPSMP15AHM3_A/H TVS diode is specifically designed to provide ESD (electrostatic discharge) protection for a wide range of applications. This TVS diode provides a very low capacitance of less than 1pF, making it ideal for protecting high-speed data lines and other high frequency circuitry. In addition, the diode has a high peak pulse current rating of 15A(8/20μs), making it very effective in withstanding very high energy transients.

The TPSMP15AHM3_A/H provides a wide operating voltage range from 5V to 28V, which is ideal for a broad range of applications. The diode also features low reverse leakage current, making it suitable for applications requiring low standby power consumption. Due to its low capacitance and high peak pulse power of 150W, it is ideal for use in high frequency or digital signal processing (DSP) applications.

The working principle is quite simple. When a voltage transient occurs, the diode’s internal circuitry is activated and a negative voltage is applied to the diode’s anode. This negative voltage creates an electric field inside the diode that absorbs the excess energy from the transient. The diode then acts as a current sink, absorbing the incoming energy and dissipating it safely as heat.

The TPSMP15AHM3_A/H TVS diode is designed for applications such as mobile phones, television receivers, modem lines, LCD panels, CD-ROM drives, and other such electronic devices. This diode is often used to protect these devices from the damaging effects of Electrostatic Discharge (ESD), which can cause permanent damage to electronics. It is also used in high-speed data transmission systems and in other high frequency equipment.

In summary, the TPSMP15AHM3_A/H is an effective TVS diode that combines a low capacitance of less than 1pF, a wide operating voltage of 5V to 28V, and a high peak pulse current of 15A(8/20μs). Its low reverse leakage current makes it suitable for applications requiring low standby power consumption. It is often used in mobile phones, television sets, LCD panels, CD-ROM drives, and other electronic devices to protect them in case of voltage transients.
