Description
Transient Diverting Suppressors(TDS) 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.
TDS4001P is designed to protect voltage bus or data
lines with an operating voltage as high as 40V. 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 IEC61000-4-5 (RS =
42 Ohms, CS= 0.5μF).
TDS4001P is in a small DFN 1.6mm x 1.6mm x 0.55mm
6- Lead package and represents significant board space
savings over traditional SMAJ and SMBJ packaged
devices.
