DESCRIPTION
The RClamp®3328P provides low voltage ESD protection for high-speed ports. It features a high maximum ESD withstand voltage of ±25kV contact and ±30kV air discharge per IEC 61000-4-2. Peak ESD clamping voltage is extremely low and approximately the same at each pin. Maximum capacitance on each line to ground is 0.65pF. These devices are manufactured using Semtech’s proprietary low voltage EPD technology for superior characteritics at operating voltages up to 3.3 volts. Each device will protect up to eight lines (four high-speed pairs). The RClamp3328P is in a 9-pin SGP3810N9 package. It measures 3.8 x 1.0mm with a nominal height of 0.50mm. Intra-pair lead pitch is 0.40mm while the pair-to-pair pitch is 0.5mm. The innovative flow through package design simplifies pcb layout and allows matched trace lengths for consistant impedance between high speed differential lines. The combination of low peak ESD clamping, low dynamic resistance, and innovative package design enables this device provides the highest level of ESD protection for applications such as USB 3.0, HDMI and V-By-One interfaces.
