Semtech Corporation has unveiled the RClamp7534P, a 4-line integrated Transient Voltage Suppression, or TVS, array designed to protect HDMI 2.0 interfaces against electrical transient threats. Targeted at the rapidly growing Ultra HD (4K2K) market featuring the new HDMI 2.0 interface, the RClamp7534P is specifically engineered to meet the rigorous signal integrity requirements of HDMI 2.0 as well as deliver robust ESD protection for highly sensitive HDMI 2.0 chipsets. Traditionally, TVS devices relied on large capacitances to improve clamping performance.

However, in next generation applications such as HDMI 2.0, having low capacitance is key to ensuring signal integrity and minimizing bit errors. The RClamp7534P features a typical 0.19pF line-to-ground capacitance and enhanced ESD immunity level (±25kV air discharge and a ±20kV contact discharge). The RClamp7534P also features an innovative flow-through package that offers a 20% PCB space saving over traditional 4-line TVS devices to accommodate space constrained designs while improving overall clamping performance.
