TVS (Transient Voltage Suppressor) diodes are a form of high-power surge protector used to protect semiconductor circuits from harmful voltage transients. SZ1SMB75CAT3G is a bidirectional TVS diode that provides outstanding performance in the protection of data lines and circuits from electric static discharge (ESD) and lightning-induced transients. It is typically deployed in devices such as data systems, LANs, and telecommunications equipment.

The SZ1SMB75CAT3G is manufactured with a proprietary process optimized for ESD and over-voltage protection. It uses a single-body structure with no exposed internal metal bonding wires, which greatly reduces the likelihood of failure due to thermal and transient overstresses. The diode is also capable of operating over a wide temperature range, from -55°C to +150°C.

The SZ1SMB75CAT3G is designed to be bidirectional and has a low turn-on voltage of just 5.6V and a low capacitance of 1.6pF. This low capacitance allows the diode to provide excellent protection at high frequencies, which makes it ideal for protecting digital circuits. The diode can also handle up to 75W of power and is capable of withstanding surge currents up to 1,500A.

The working principle of the SZ1SMB75CAT3G is quite straightforward. When a transient voltage is applied to the diode, the diode conducts by turning on its internal avalanche breakdown mechanism. This triggers a currentPath that rapidly dissipates the surge energy and protects the semiconductor components from damage. The diode then turns off when the voltage returns to normal.

The SZ1SMB75CAT3G is commonly used to protect circuits in computers, network equipment, telecom systems, and consumer electronics, as well as medical and automotive applications. It can help reduce the risk of voltage transients caused by lightning, ESD, over-voltage, and other forms of surge current, making it an invaluable part of electronics protection.
