TDS2621LP Transient Diverting Suppressors (TDS)

Semtech TDS2621LP Transient Diverting Suppressors (TDS) are designed to provide high-energy electrical overstress (EOS) protection with superior clamping and temperature characteristics when compared to standard TVS devices. The Semtech TDS2621LP devices use 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 then switches on and conducts a 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 [R_DS(on)] of the FET. Lower clamping voltage at maximum peak pulse current makes the TDS components more suitable for protecting sensitive integrated circuits (ICs), when compared to standard TVS diodes.
