RClamp0501T Low Capacitance 1-Line ESD protection 

## **PROTECTION PRODUCTS** - RailClamp **[®]** 

## Description 

RailClamp[®] TVS arrays are ultra low capacitance ESD protection devices 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 RClamp[®] 0501T has a maximum capacitance of only 1.5pF.  This allows it to be used on circuits operating in excess of 100MHz without signal attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2. 

The RClamp0501T is in a 2-pin SLP1006P2T package measuring 1.0 x 0.6 x 0.4mm.  The leads are spaced at a pitch of 0.65mm and feature a lead-free finish. Each device will protect one high-speed line operating at 5 volts.  It gives the designer the flexibility to protect single lines in applications where arrays are not practical.  The combination of small size, low capacitance, and high ESD surge capability makes them ideal for protection of high speed digital lines in cellular handsets and other portable electronic devices. 

## Features

## Device Connection Options 

## Equivalent Circuit Diagram 

These low capacitance TVS diodes are designed to provide common mode protection for one high-speed line.  The device is unidirectional and may be used on lines where the signal polarity is positive. 

## Circuit Board Layout Recommendations for Suppression of ESD. 

Good circuit board layout is critical for the suppression of ESD induced transients.  The following guidelines are recommended: 

- Place the TVS near the input terminals or connectors to restrict transient coupling. 

- Minimize the path length between the TVS and the protected line. 

- Minimize all conductive loops including power and ground loops. 

- The ESD transient return path to ground should be kept as short as possible. 

- Never run critical signals near board edges. 

- Use ground planes whenever possible.
