Transient voltage suppression diodes, commonly referred to as TVS-diodes, are discrete semiconductor devices used to protect electronic circuits and systems from overvoltages caused by power line transients. They are designed to clamp, limit, and/or absorb transient voltage surges, thereby protecting the circuit or system from damage. The ATV04A101JB-HF is a high-speed, surface-mount transient voltage suppression (TVS) diode specifically designed for circuit protection applications.

The ATV04A101JB-HF is a unidirectional high-speed diode in an SOD-323F package with a dc stand-off voltage of 10V and a peak pulse power of 2.3kW (10/1000μs). The device is made from ultra-fast, ultra-low capacitance silicon technology and has a breakdown voltage of 11.2V. The device offers excellent clamping capability, fast response time to transient voltage spikes, and low leakage current. It is designed for applications requiring high performance, reliability, and wide operating temperature range.

The chip is AEC-Q101 qualified and meets the RoHS (Restriction on Hazardous Substances) standard for lead-free components. The package is halogen-free, making it environmentally friendly and compliant with the REACH environmental regulations. The device is available in a variety of configurations, including bidirectional, surface-mount and through-hole, and is suitable for a wide range of applications.

In terms of its application field, ATV04A101JB-HF can be used to protect sensitive electronics from high voltage transients caused by power line transients. The device can be used in a wide range of applications, including automotive, consumer electronics, industrial, and medical systems. It is also suitable for use in smart phone, notebook computers, and other portable devices. In the automotive industry, the device can be used to protect ECUs from overvoltage. In medical equipment and other sensitive applications, it can be used to prevent damage caused by electrical surges and spikes.

The ATV04A101JB-HF’s working principle is based on its avalanche breakdown voltage, which is typically greater than the breakdown voltage of a regular diode, allowing it to clamp and absorb a larger amount of transient energy. When a voltage transient greater than the breakdown voltage is applied to the diode, its junction enters an avalanche breakdown mode. In this mode, the diode absorbs the transient energy and clamps the voltage to the breakdown voltage, thus protecting the circuit or system from damage.

The ATV04A101JB-HF is an ideal solution for circuit protection applications. Its ultra-fast response time, low capacitance, and high clamping voltage make it an ideal choice for protecting sensitive electronics from transient voltage surges. It is robust, reliable, and easy to use, making it well suited for a wide range of applications. It is also RoHS-compliant and environmentally-friendly, making it an ideal choice for applications requiring compliance with environmental regulations.
