TVS (transient voltage suppressor) diodes are commonly used to increase the surge protection capabilities of most withstanding circuits from voltage overloads and circumstances. Among them, the ATV02W190-HF TVS diode provides a cost-effective and reliable protection against both transient surges and EOS (electrical overstress). This article will discuss the application field and working principle of the ATV02W190-HF.

Application field of ATV02W190-HF:

The ATV02W190-HF is designed as a high power and long wave diode for over-voltage protection of various lines. It has a fast response time of 200ns, allowing it to operate during even the most severe transient events. It also includes an improved thermal management to minimize self-heating while protecting from transient overvoltages. This makes it suitable for a wide range of applications, such as industrial, automotive, railway, consumer electronics, power supply, and communication. ATV02W190-HF diodes are commonly used to protect high-speed data buses, such as those found in automobile, industrial, computer and telecommunications systems.

Working Principle of ATV02W190-HF:

The ATV02W190-HF is a single-stage TVS diode, which operates on the principles of avalanche breakdown. When the voltage across the diode exceeds the breakdown voltage, the current through the diode increases rapidly, causing the diode to dissipate power and clamp the voltage to a safe level. During normal operation, the diode is non-conductive, therefore no power is dissipated. The breakdown voltage of the ATV02W190-HF is 190V, with a maximum reverse transient current of 2A and peak pulse power of 200W.

ATV02W190-HF diodes are designed to handle relatively high power transients, allowing them to protect a wide range of devices from lightning surges and other high-voltage over-current events. Furthermore, their fast response time allows for instantaneous activation, providing quick protection for devices connected to the protected line. This makes them ideal for use in high-speed applications.

Conclusion:

The ATV02W190-HF is an ideal choice for those looking for a reliable and cost-effective TVS diode. Its robust design makes it suitable for a wide range of applications, while its fast response time allows it to provide quick protection when a high-voltage surge or transient event occurs. With a breakdown voltage of 190V, a maximum reverse transient current of 2A and a peak pulse power of 200W, it can easily handle most surges and over-voltage events.
