TV50C450JB-G is an ultra low capacitance and bidirectional unidirectional transient voltage suppressor device with a breakdown voltage of 5.0V. The low capacitance and low leakage current reduce the output power of the system, reducing power consumption and increasing the performance of the system.

Application Field

TV50C450JB-G is a popular choice for ESD protection in a variety of consumer and industrial electronics markets, such as media players, set-top boxes, white goods, home appliances and automotive applications. The excellent overvoltage protection and low clamping voltage of TV50C450JB-G make it the perfect choice for applications requiring reliable protection in the face of high voltage spikes.

The device is also well suited for use in power supplies, which can easily be damaged by transients and overvoltage. The low capacitance of the device allows it to be used in low-power applications, such as SIM cards, card readers, and data loggers. In these applications, the low capacitance of the TV50C450JB-G minimizes the power used by the system, improving system performance.

Working Principle

TV50C450JB-G is an advanced TVS (Transient Voltage Suppressor) diode that works on the principle of avalanche breakdown. The device is designed with a PN junction having an increased doping level, and the reverse voltage applied across the PN junction increases the electric field strength. When the electric field increases to a certain level, the electrons and holes in the PN junction will accelerate and collide with each other, forming an electrical avalanche effect. This will eventually lead to a breakdown, and the breakdown voltage is determined by the structure of the PN junction and its doping concentration.

When the TV50C450JB-G device is subjected to an overvoltage or a transient voltage surge, the device will quickly conduct current, clamping the voltage at its rated breakdown voltage. The device’s low capacitance ensures that it quickly discharges the surge current, preventing damage to the system. The low leakage current ensures that the device will not consume excess power and reduce the performance of the system.

The TV50C450JB-G device is designed to be highly reliable and produce repeatable performance. The device features an increased thermal coefficient of breakdown voltage, which allows it to withstand higher temperatures without compromising its voltage rating. The device also features a low turn-on voltage, which minimizes the possibility of false triggering. Thus, the TV50C450JB-G device is an extremely dependable solution for transient voltage suppression.
