RailClamps are ultra low capacitance TVS arrays designed to protect high speed data interfaces. This series has been specifically 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 RClampTM0522P and RClampTM0524P have 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 RClamp0522P is designed to protect two lines, while the RClamp0524P will protect four lines. The RClamp0522P is in a 6-pin, RoHS/WEEE compliant, SLP1610P4 package. It measures 1.6 x 1.0 x 0.58mm. The RClamp0524P 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.
The RClamp0522P and RClamp0524P are ultra‑low‑capacitance TVS (Transient Voltage Suppressor) arrays designed to protect high‑speed data lines such as HDMI, DVI, DisplayPort, MDDI, PCI‑Express and Serial ATA from ESD, cable discharge events and electrical fast transients. They meet IEC 61000‑4‑2 Level 4 (+15 kV air, +8 kV contact) and IEC 61000‑4‑5 lightning requirements.
The RClamp0522P comes in a 6‑pin SLP1610P4 package (1.6 × 1.0 × 0.58 mm) and protects two I/O lines, while the RClamp0524P uses a 10‑pin SLP2510P8 package (2.5 × 1.0 × 0.58 mm) and protects four lines. Both feature a typical capacitance of 0.30 pF between I/O pins, a low clamping voltage, and a 5 V operating voltage. Recommended PCB layout places the device close to the connector and uses short return paths with multiple micro‑vias.
