TVS - Diodes - Application Field and Working PrincipleTVS (Transient Voltage Suppressor) Diodes are components designed to protect sensitive electronic systems from overvoltage and power surge events. They are commonly found in systems which use sensitive devices, such as microcontrollers, integrated circuits, and FPGAs (Field Programmable Gate Arrays). The particular device under investigation is the 30KP28A-TP, also known as the 30KP28 Series Transient Voltage Suppressor.This 30KP28A-TP device has a reverse bias breakdown voltage of 28 V, a Breakdown Voltage Tolerance of +-1.2 V, and a Max Operating Junction Temperature of 150°C. It has a fast response time (less than 1.0 nanoseconds to peak) and a low maximum clamping voltage (less than 40V). It is also capable of withstanding power surges of up to 9.3A (1000 Watts max). This makes it suitable for protecting systems from the very common transients caused by power outages, electrostatic discharges, and even lightning.The 30KP28A-TP is available in a variety of packages, including axial and SMD (surface mount) varieties. The particular part that we are considering is the DO-27 package, which is axial. This is a two-pin package, with a cathode and an anode. The cathode is marked in the case of the 30KP28A with a “K” and the anode is marked with a “B”.The 30KP28A-TP works on the principle of a PN junction diode. It is designed such that when a voltage higher than its reverse breakdown voltage is applied to the anode of the device, the PN junction is reversed biased and its path blocked. This, combined with its fast response time – less than 0.5 nanoseconds to peak – allows it to clamp the voltage very quickly, leaving any sensitive components behind it unharmed.The 30KP28A-TP is commonly used to protect systems which are exposed to overvoltage and electrical surge events. Some of the applications which it is used to protect include computers, telecommunication systems, automotive electronics, medical equipment, microprocessor-based systems, and consumer electronics. It is also widely used in industrial applications, making it suitable for a variety of applications.In conclusion, the 30KP28A-TP is a robust, reliable, and fast-responding device which is capable of withstanding power surges and transient voltage events. It is available in a number of packages and is suitable for a variety of applications. It works on the principle of a PN junction diode, and its design allows it to quickly clamp the voltage, thus protecting the sensitive components behind it.
