描述 Description

Transient diverting suppressors (TDS) are designed to provide high energy electrical overstress (EOS) protection with superior clamping and temperature characteristics when compared to standard transient voltage suppressor (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.
