TVS - Diodes

TVS - diodes, also known as Transient Voltage Suppression diodes, are electronic components designed to protect sensitive electronics from high voltage surges. They are integrated circuits (ICs) that protect against voltage surges from lightning strikes, accidental contact with high-voltage power sources, and transient voltage spikes caused by circuit inductance. TVS-diodes are used in a wide variety of applications, such as communications systems, electrical and automotive equipment, power supplies, and others.

TV04A441JB-HF Application Field and Working Principle

TV04A441JB-HF is a TVS diode designed for transient voltage and inductive switching applications. It combines a low clamping voltage with low capacitance, providing a wide range of protection options for high voltage, high current environments. The TV04A441JB-HF features a surge current rating of 8.3A (10/1000microsec) and a peak pulse power rating of 600W (8/20microsec).

The working principle of the TV04A441JB-HF diode involves clamping, or limiting, of the voltage levels to a predetermined value. When a voltage higher than the protected voltage level is applied, the TVS diode will turn on, effectively shorting the two terminals and redirecting the extra voltage away from the circuit. Once the transient voltage is clamped, the TVS diode will immediately turn off, preventing any damage to the protected circuit.

The TV04A441JB-HF TVS diode is suitable for a wide range of applications, including industrial manufacturing automation systems, automotive and motor components, telecom equipment, portable electronic devices, and others. It is capable of providing high-speed EMI filtering and transient voltage protection, and is suitable for use in high-voltage and high-current environments.

The TV04A441JB-HF is designed to meet IEC 61000-4-2 and IEC 61000-4-5 requirements for EMI suppression and transient voltage protection. It is also UL94V-0 rated, indicating its ability to withstand high temperatures. With its wide surge current rating and peak pulse power rating, the TV04A441JB-HF is an ideal choice for protecting sensitive electronics from high voltage surges.
