Overview
SurgeSwitch™ are designed to provide high energy EOS protection with superior clamping and temperature characteristics when compared to standard TVS devices. The device uses a surge rated FET as the main protection element. During an EOS event, transient voltage increases beyond the rated breakdown voltage of the device. The FET in turn switches on and conducts transient current to ground. The TDS clamping voltage is nearly constant across the rated peak pulse current range due to the extremely low ON Resistance of the FET. Lower clamping voltage at maximum peak pulse current makes them more suitable for protecting today's sensitive IC's, when compared to standard TVS diodes. TDS5311P is designed to protect voltage bus or data lines with an operating voltage as high as 53V. It is rated for a high-energy transient current up to 24A (tp = 8/20μs) and may be used to meet the common industrial voltage surge standard of ±1kV per IEC 61000-4-5 (RS =42Ω, CS= 0.5μF). TDS5311P is in a small 2.0 x 2.0mm, 6-pin DFN package and represents significant board space savings over traditional SMAJ and SMBJ packaged devices.
