TV50C131JB-G Application Field and Working Principle

The TV50C131JB-G is an ultra low capacitance, ultra-wide bandwidth unidirectional TVS (Transient Voltage Suppressor) diode. It is mainly used in high speed data line and interface protection, over-voltage protection and ESD protection.It provides low leakage current, low clamping voltage, high and fast response to high frequency transients without false triggering and maximum conformal coating compatibility.

Working Principle

The working principle of the TV50C131JB-G is based on integrated, dual array design. The integrated diode consists of two arrays, each with an individual NPN transistor. When the voltage exceeds certain levels, the NPN transistors open, connecting them in parallel and resulting in a sharp increase in current. This causes the TVS diode array to effectively short out the excess current.

Applications

The TV50C131JB-G is typically used in various applications such as high speed data line and interface protection, power over-voltage protection, ESD protection, and surge protection. It can be used to protect high speed data interfaces, such as USB 2.0, Serial ATA, and PCI Express. It is also suitable for protecting power lines and signals in both AC and DC low voltage applications. Its ultra-low capacitance, wide bandwidth, and fast response make it ideal for use in high speed signal lines, protecting them from voltage spikes.

Features

The key features of the TV50C131JB-G include: ultra-low capacitance (2 pC typical); high ESD protection (IEC 61000-4-2; Level 5, 8kV contact discharge; Level 6, 15kV air discharge); ultra-wide bandwidth (up to 8GHz); fast response time (less than 1ns); low leakage current (less than 1.8nA); minimum clamping voltage (28V typical); and RoHS compatible version.

Conclusion

The TV50C131JB-G is an ultra low capacitance, ultra-wide bandwidth unidirectional TVS diode which is mainly used in high speed data line and interface protection, over-voltage protection, and ESD protection. Its wide bandwidth, fast response time, and low leakage current make it ideal for protecting high speed data interfaces and signals from voltage spikes.
