WTCLAMP0524P Ultra Low Capacitance TVS Arrays P b Lead(Pb)-Free Mechanical Characteristics: WTCLAMP0524P is ultra low capacitance TVS arrays designed to protect high speed data interfaces. WTCLAMP0524P has been specifi cally designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The WTCLAMP0524P has a typical capacitance of only 0.30pF between I/O pins. This allows it to be used on circuits operating in excess of 3GHz without signal attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The WTCLAMP0524P is in a 10-pin, RoHS/WEEE compliant, SLP2510P8 package. It measures 2.5 x 1.0 x 0.58mm. The leads are spaced at a pitch of 0.5mm and are finished with lead-free NiPd. They are designed for easy PCB layout by allowing the traces to run straight through the device. The combination of small size, low capacitance, and high level of ESD protection makes them a flexible solution for applications such as HDMI, UDI, DisplayPortTM, MDDI, Serial ATA, and Infiniband circuits.

First, ESD protection devices have an inherent junction capacitance. However, adding even a small amount of capacitance will cause the impedance of the differential pair to drop. Second, large packages and land pattern requirements cause discontinuities that adversely affect signal integrity. The WTCLAMP0524P are specifi cally designed for protection of high-speed interfaces such as HDMI. They present <0.4pF capacitance between the pairs while being rated to handle >±8kV ESD contact discharges (>±15kV air discharge) as outlined in IEC 61000-4-2. Each device is in a leadless SLP package that is less than 1.1mm wide. They are designed such that the traces flow straight through the device. The narrow package and flow through design reduces discontinuities and minimizes impact on signal integrity. This becomes even more critical as signal speeds increase.
