Basic Information

• Part Number: RClamp0504FA
• Manufacturer: Semtech Corporation
• Website: www.semtech.com
• Revision Date: 4/15/2010
• Package Type: SC-70, 6-pin

Description

The RClamp0504FA is a low capacitance TVS (Transient Voltage Suppressor) array designed to protect high-speed data interfaces. It is specifically designed to protect sensitive components connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The device incorporates surge-rated, low capacitance steering diodes and a TVS diode in a single package, allowing it to absorb large amounts of energy while protecting downstream components from harmful transient events.
