TPC20AHM3_A/H

TVS diodes are an important technology for mitigating the effects of external electrical disturbances. The TPC20AHM3_A/H is an example of a TVS diode with a wide range of applications and a unique working principle.TVS diodes are commonly used in automotive, aerospace, communication and power electronics systems, where protection against external electrical transients is important. The TPC20AHM3_A/H is a robust and reliable surface-mount device designed to protect sensitive circuits from over-voltage transients. It is a bidirectional device with a 17 V working voltage and 11 V clamping voltage, making it suitable for a wide range of applications.In terms of its working principle, the TPC20AHM3_A/H utilizes an avalanche breakdown phenomenon, as do other TVS diodes. This is a unique process that occurs when the voltage across the p-n junction exceeds a certain threshold value, causing electrons within the junction to gain sufficient energy to overcome the potential barrier and then conduct current. When a voltage surge is detected, the avalanche breakdown mechanism of the TPC20AHM3_A/H is activated and it rapidly conducts current from the surge to ground. This prevents the surge from damaging other components by dissipating its energy and also by reducing the surge voltage. The TPC20AHM3_A/H therefore acts as a voltage clamp, limiting the voltage across the component to a safe level. The TPC20AHM3_A/H also features a wide working temperature range from -55°C to+150°C, making it suitable for extreme temperature applications. It has a wide operation frequency range of 0-1MHz, and its response time is very fast at only a few nanoseconds. It also has a high surge capability of up to 500A.In conclusion, the TPC20AHM3_A/H is a reliable surface mount TVS diode with a wide range of applications and a unique working principle. The avalanche breakdown mechanism utilized by this diode enables it to protect sensitive components from over-voltage transients, while its wide working temperature range, wide operation frequency range, and fast response time make this TVS diode a great choice for a wide range of applications.
