TVS - Diodes

TVS (Transient Voltage Suppressors), is an electronic device used for protecting electronic circuits, from voltage surges caused by overcurrent or ESD (Electro-Static Discarge). TVS are available in a variety of sizes, styles, and ratings, and are made from different technologies such as bipolar, unipolar, diode array, varistor, and tunnel diode.

SZ1SMB7.0AT3G is a uni-directional TVS, specifically designed to be used in applications with 3-phase AC wirings, such as Industrial, Automotive, Telecom, and Home Appliances. It provides protection against surges such as spikes and ESD, and offers low clamping voltage, fast response time, robust design, and excellent long-term reliability.

Application Field

The SZ1SMB7.0AT3G is suitable for a wide range of applications in different fields, including:

• Factory automation equipment
• Medical equipment
• Industrial and Automotive Wiring Systems
• Telecommunications systems
• Security systems
• Home appliances and ITE Equipment

Working Principle

The SZ1SMB7.0AT3G operates in a uni-directional mode, in which heavy and fast-rising 10/1000µs surge current are stopped and diverted to ground, while allowing normal currents to pass freely.

The TVS is made up of an array of diodes, connected in series and connected between the two power lines. When a normal current passes through the TVS, the voltage drop across the diode array is small, resulting in minimal power loss in the circuit. However, if a higher voltage is applied to the circuit, the TVS will act as a surge protector, allowing the excess voltage to bypass the circuit and be dissipated safely in the ground. The TVS is able to respond quickly to these peak surges, providing reliable protection to the circuit.

The SZ1SMB7.0AT3G offers high ESD immunity up to 10kV, low leakage current of 12µA, high peak current of 600A, and fast response time of 20ns maximum. It also has a robust design, making it suitable for use in a wide range of applications.

Conclusion

SZ1SMB7.0AT3G is a uni-directional TVS, specifically designed for 3-phase AC wirings. It provides protection against surges such as spikes and ESD, and offers low clamping voltage, fast response time, robust design, and excellent long-term reliability. It is suitable for a wide range applications in different fields, and is a reliable solution for protecting electronic circuits from overvoltage and ESD.
