RClamp0524S
RClamp0524S is Low Capacitance TVS Diode Array manufactured by SEMTECH.
PROTECTION PRODUCTS
Description
Rail Clamps® are low capacitance TVS arrays designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive ponents which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients).
The unique design incorporates two identical circuits. Each circuit is prised of surge rated, low capacitance steering diodes and a TVS diode in a single package. During transient conditions, the steering diodes direct the transient current to ground. The internal TVS diode clamps the transient voltage to a safe level. The RClamp0524S has a low maximum capacitance of only 5p F per line. Each device will protect up to four data lines. The dual circuits make it ideal for applications like power over Ethernet (Po E) where each signal pair sits at a different potential.
The RClamp TM0524S is in a 6-pin, Ro HS/WEEE pliant, SOT-23 package. The leads are finished with leadfree matte tin. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15k V air, ±8k V contact discharge).
