TVS - Diodes
TVS-Diodes, the acronym by which they are commonly known, is a type of semiconductor that is a special type of diode used in various electronics applications. TVS-diodes are primarily used for protection in electronics, for example in power supplies, circuit boards, and other electronic components. TVS-diodes provide protection against electrical transients, such as high-voltage spikes or ESD (electrostatic discharge). They are designed to turn on (clamp) at a certain voltage and conduct the initial surge of current across them while protecting the device they are protecting. TVS-diodes are commonly used in consumer electronics, automotive, military, aerospace, solar, and industrial applications.
One such such TVS-Diode is the ATV04A330JB-HF. The ATV04A330JB-HF is a bidirectional transient-voltage-suppressor diode (TVS) designed for ESD suppression. The ATV04A330JB-HF is certified to protect against ESD events of up to ±15 kV contact discharge according to IEC61000-4-2 level 4. It has a maximum clamping voltage of 27.7 V for a 5 A peak pulse current. It is rated for reverse leakage current of less than 100 nA at 5 V and a capacitance of 4 pF typ @ 1 V for ESD protection. The ATV04A330JB-HF features an ultra-low-profile of 0.35 mm and an ultra-small package size of 2x2 mm with a unique UESD body for reliable protection against ESD events. This TVS-Diode is widely utilized in consumer and professional electronics, automotive, and industrial applications.
The working principle of the ATV04A330JB-HF is essentially the same as with any other TVS-Diode. When a voltage spike or ESD event occurs, the diode is immediately triggered and the current is clamped at the Peak Pulse Power rating of 5A. This clamps the voltage below the specified maximum clamping voltage of 27.7V, thus protecting the device from damage. Once the transient event has passed, the diode turns off and normal operations can resume.
In conclusion, the ATV04A330JB-HF is a TVS-Diode designed for ESD suppression, with a maximum clamping voltage of 27.7 V for a 5 A peak pulse current. It is widely used in consumer and professional electronics, automotive, and industrial applications. The ATV04A330JB-HF’s ultra-low-profile of 0.35 mm, small package size of 2x2 mm, and a unique UESD body allows for reliable ESD protection. The working principle of the diode is to clamp the current at a certain voltage when a voltage spike or ESD occurs, thus protecting the device from damage.
