TVS - Diodes are an electrical component used to protect certain electronics from damaging power surges or spikes. They operate by conducting a current away from sensitive components when a voltage higher than a threshold is encountered. TV04A220J-G is an ultra-low capacitance diode designed to protect sensitive devices sensitive to ESD (electrostatic discharge) pulses and electrical surges such as TV tuners or optical drives. This article will focus on the application field of the TV04A220J-G, as well as its working principle.

The TV04A220J-G is capable of dissipating up to 3 kV of transients compared to other ESD devices capable of only 2 kV. This allows the device to better protect systems from higher levels of electrical shock. The device also has a low capacitance of 2.7pf which makes it easier to place on the circuit board and not interfere with signal frequencies. Its low capacitance also means the device can be used in fast clock systems up to 16 MHz. TV04A220J-G has 4-Pin SMC package, characterized by 3 kV ESD resistance, low capacitance and fast recovery. It is suitable for a wide range of applications, such as high-speed communication ports, TV tuners, optical drives, consumer electronics and other high-speed applications.

The TV04A220J-G diode begins to conduct when subjected to an electrical surge, clamping excessive voltages before they damage sensitive components. The voltage is then discharged through a low impedance fused path, protecting the device and other components from experiencing excessive voltage. The device has a maximum peak current rating and a standoff voltage rating, indicating how much current it can cycle through and for how many voltage levels it is designed to operate. The TV04A220J-G clamp voltage is adjustable, allowing for the device can be designed for different breakdown levels.

TV04A220J-G has two ways of operation. When subjected to a low level transient, the device triggers a fast-recovery diode, quickly focusing and discharging the transient to ground. When the transient reaches a certain level, the high-current diode is triggered. This absorbs the majority of the current and sends it back to the source, ensuring that no damage is done to the device or other components.

TV04A220J-G is an ideal component for protecting against transient voltage and lightning-induced voltage transients. Its ultra-low capacitance means it doesn’t interfere with signal frequencies and its adjustable clamp voltage can be tailored to an application’s needs. Furthermore its low-current break over and ESD resistance offered nearly twice that of similar devices ensure its durability and longevity; making it the perfect choice for applications requiring transient voltage and surge protection.
