TVS - Diodes are used to provide protection against transient pulses, generally during times of power interruption or electrical spikes. They are used to protect circuits from possible damage due to high-voltage transients, such as electrostatic discharge (ESD).TV15C200JB-HF is one type of TVS - Diodes, and is a high-performance, low-capacitance, bi-directional ESD protection diode array.

Application Field
The TV15C200JB-HF is designed primarily for the protection of high-speed data lines and ports against the damaging effects of electrostatic discharge. It can be used in applications such as computers, servers, handheld devices, cellular phones, industrial equipment, and other high-speed data line applications.

Working Principle
The working principle of TV15C200JB-HF is that it works by utilizing a breakdown voltage (including a clamping voltage). The breakdown voltage of the TV15C200JB-HF is much higher than the normal operating voltage of the system, so when a transient voltage pulse occurs, its clamping voltage can absorb the transient pulse, protecting the circuits and components at the front end. The TV15C200JB-HF diode also has excellent ESD Immunity, able to withstand an ESD pulse of up to 8kV.

The TV15C200JB-HF has two ultra-low clamping diodes in opposite directions, which are connected in parallel with two 5Ω resistors in series. The 5Ω resistors reduce the parasitic capacitance of the diode, eliminating the potential for damage from the overvolting due to the coaxial capacitance, increasing the isolation and ESD immunity. Additionally, the TV15C200JB-HF has built-in ESD protection for LEDs, allowing them to protect up to 30V.

The TV15C200JB-HF also has a very high surge capability and very low dynamic resistance. Its surge capability is rated at 6.7A for 5/50 ns, with a very low dynamic resistance of 250mΩ, making it ideal for protecting high-speed data lines and ports. Additionally, the TV15C200JB-HF comes in a very small, 0603 size, making it ideal for space-constrained applications.

To sum it up, the TV15C200JB-HF is an excellent choice for protecting high-speed data lines and ports, as it is able to absorb transient pulses, and provide excellent ESD immunity up to 8kV. Additionally, it has very low clamping diodes, excellent surge capability, and is small in size.
