TVS diodes, otherwise known as Transient Voltage Suppressors (TVS) diodes, have a wide range of applications in almost every industry. From protecting consumer electronic products from surges to in automotive and aviation industries to help limit voltage transients, these robust solutions have been designed to provide fail-safe protection for electronic systems. The UCLAMP3301H.TCT TVS diode is one such diode that fits perfectly into this product segment.

The UCLAMP3301H.TCT is available in an SOT23-6L package and is designed to protect sensitive automotive and avionic circuitry. The diode offers clamping, ESD, and surge protection in a compact, 6-pin package, which reduces PCB real estate requirements. The diode also incorporates a VSWR (Voltage Slope Resistance) structure that enables it to precisely detect and clamp spikes in voltage at lower energy levels. In addition, the VSWR clamping technology employed in the UCLAMP3301H.TCT helps to reduce stress placed on the ESD junction.

The protection circuitry employed in the UCLAMP3301H.TCT will limit the surge voltage transients while allowing the normal signal to pass through without significant interruption. The capacitively coupled solid-state device is designed to respond to positive overvoltage events up to +36V (7.6V clamping voltage at Ipp = 10A), and to negative overvoltage events up to −36V (7.6V clamping voltage at Ipp = 10A). The robust surge protection provided by the UCLAMP3301H.TCT will absorb up to 200A (2/10μs pulse) of energy from large surges without energetic breakdown, preventing system damage or malfunction.

The UCLAMP3301H.TCT is an inherently bidirectional device that will protect sensitive circuits from both incoming and outgoing transients. The device also features a low holding voltage that minimizes FET parasitic effects. It has a low and reverse leakage current, allowing it to function as a clamp over a wide temperature range. The diode also has a high ESD withstands voltage of ±8kV.

The UCLAMP3301H.TCT is designed to address a wide range of applications, including automotive systems, avionics, consumer electronics, telecommunications, and industrial safety networks. The device is characterized for operation between -55°C to 175°C and is RoHS compliant. The device is compatible with the HBM and HCBM IEC 61000 standard and is UL 94V-0 rated for flame retardance, making it an ideal choice for protecting a wide range of sensitive electronics.

In summary, the UCLAMP3301H.TCT is a robust and reliable TVS diode designed to provide fail-safe protection from transient voltage surges. The VSWR clamping technology employed in the diode affords it a wide operating range and precise detection and clamping of spikes in voltage. The device is suitable for a wide range of applications, including automotive systems, avionics, consumer electronics, telecommunications, and industrial safety networks. It is UL 94V-0 rated for flame retardance, and is characterized for operation between -55°C to 175°C and is RoHS compliant.
