TVS (Transient Voltage Suppressor) diodes are used to provide transient protection for sensitive electronic circuits and components. They are available in many shapes and sizes for bare board or surface mount designs. The V120ZA1 is a highly reliable bi-directional TVS diode, designed to protect USB ports, Ethernet ports, and other port connectors. It is available in a TO-252AA package and features an integrated protection circuit, making it ideal for applications that require robust surge protection.

The V120ZA1 is a Uni-directional TVS (Transient Voltage Suppressor) device that protects a circuit from over voltage transients resulting from static discharge, lightning strokes, or other causes of elevated voltages. It is rated for up to 20V peak, has a peak power dissipation of 1050W, and can dissipate a peak pulse current of 1200A. It offers excellent transient surge protection for data ports, telecom, consumer electronics, and industrial applications.

The V120ZA1 has a simple working principle based on a two diode circuit. One diode is connected in reverse bias, while the other diode is connected in forward bias. When a voltage that is higher than normal is applied to the diode, the reverse bias diode will become lightly electron-rich and begin to conduct. The forward bias diode will act as a clamp to provide a path for the electrons to flow. This prevents the over voltage from damaging the circuit.

The V120ZA1 is designed to provide 20V of protection in applications from -40 to +85°C. It offers a low capacitance of 1.0pF between the protected signal and the ground, ensuring it will not adversely affect the data integrity of USB and other signals that are sensitive to capacitance loading. It also features an integrated MOV (Metal Oxide Varistor) for added protection in high-transient power pops, power surges, and over-voltage conditions.

The V120ZA1 is designed for a wide range of applications including handheld electronics, USB ports, and other power ports. It is suitable for protecting sensitive data and audio/video signals, and can be used in Ethernet ports and other port connectors. It is also ideal for providing transient overvoltage protection in consumer electronics, telecom, and industrial applications, as well as medical and automotive applications.

Overall, the V120ZA1 is an excellent choice for providing transient protection for sensitive electronics and components. It features a highly reliable bi-directional TVS diode with an integrated protection circuit and is available in a TO-252AA package. It offers a peak power dissipation of 1050W and a peak pulse current of 1200A, with a low capacitance of 1pF. The V120ZA1 is perfect for protecting data ports, telecom, consumer electronics, and industrial applications.
