TVS diodes (transient voltage suppressors) are devices designed to protect sensitive electronics, such as integrated circuits, against voltage spikes. The UCLAMP3311Z.TFT is a bi-directional, low capacitance TVS diode, specifically designed to protect high-speed data lines. It is an integrated solution combining low-capacitance Reverse Stand-Off Voltage (RSOV) diode and Parallel Connected Leakage Limiting Zener (PCLZ) diode, providing robust ESD and EFT protection to data lines and circuits.

UCLAMP3311Z.TFT offers superior protection performance with 5kV (Contact Discharge) 8kV (Air Discharge) ESD protection and 19.2A EFT surge current. Its advanced silicon-aided design and packaging technologies reduce capacitance loading to less than 0.7pF in parallel connection configuration, delivering high-speed data integrity performance. It is compliant with IEC 61000-4-2 level 4 and JEDEC component sensitivity ratings UL6111 and ULD6111.

UCLAMP3311Z.TFT is a three-line, tri-mode protection device, offering protection solutions such as RSOV and PCLZ series. The RSOV mode offers reliable data-line protection against ESD and EFT events, while the PCLZ mode protects the IC against ESD, EFT and reverse surges. Thus, the device provides robust and integrated protection for microelectronic systems and logic circuits.

UCLAMP3311Z.TFT is designed to protect against high voltage surges and works by clamping down the voltage within a certain threshold. The device employs a transistor-based clamping system that allows it to limit the voltage crest to a maximum safe voltage level. The threshold voltage of the UCLAMP3311Z.TFT is above 5V, meaning that any voltage beyond 5V will be clamped down. When a surge in voltage is applied to the system, the device will clamp down to the threshold voltage, absorbing the energy of the surge and preventing any component damage.

UCLAMP3311Z.TFT is widely used in various consumer electronics applications, such as mobile phones, tablets, laptop computers, televisions and smart-home systems. It is also used in industrial, automotive, medical, LED, home appliance and other applications. The device is available in various packages, including micro SMD, SOT-23 and DFN. Its wide temperature range (-40°C to 125°C) makes it suitable for use in a variety of operating environments.
