TV04A441J-HF belongs to a kind of Transient Voltage Suppression (TVS) Diode or Surge Absorption Diode.

The primary function of this kind of diode is to protect electronics from damaging surge of current and voltage. The TV04A441J-HF has been developed to provide superior protection against electrical transients in power sourcing systems, such as Point-of-load (POL), dc-dc converters, 1-4S Li-ion battery, and LED driver applications. It is designed to protect sensitive electronic equipment from transients generated by lightning activity or other electrical disturbances.

This TV04A441J-HF has a bi-directional design, meaning it can protect against current flow in either direction into or out of the protected device, by physically restraining in the breakdown voltage.

It is an excellent choice for surge protection and voltage regulation against over-voltage and over-current conditions, due to its robust power dissipation capability, high ESD tolerance, and small form factor.

This diode is ideal for a wide range of applications. It is especially suitable for use in automotive, industrial, telecommunication, consumer, and other power sourcing systems.

The working principle of the TV04A441J-HF is based on a reverse-biased diode junction that blocks current flow until the applied voltage reaches the breakdown voltage rating, and then the nonlinear junction absorbs very large amounts of energy.

The diode has a reverse-biased junction that limits the peak voltage of Vpeak 1 = 5Vmax, and peak voltage of Vpeak 2 = 6Vmax. The peak current is designed to ensure an optimal level of protection for sensitive electronic components in the event of an over-voltage surge. The breakdown voltage rating has a wide range of sustainability, typically ranging from 5V to 220V.

The device has a high holding current capability, which helps the diode to sustain its low leakage until the transient energy level has been exceeded. This capability enables the device to remain stable, even during high-frequency or long-duration waveforms.

In summary, the TV04A441J-HF is a high-performance Transient Voltage Suppression (TVS) Diode or Surge Absorption Diode designed to provide superior protection against electrical transients in power sourcing systems. It is an ideal choice for protecting sensitive electronic components from over-voltage transients, due to its robust power dissipation capability, high ESD tolerance, and small form factor.
