Description
Transient Diverting Suppressors (TDS) are designed
to provide protection from Electrical Overstress (EOS)
events. They have superior clamping and temperature
characteristics when compared to standard TVS devices.
The device uses a surge rated FET as the main protection
element. A precisely tuned trigger circuit activates the
shunt FET when an EOS event is detected. The TDS
clamping voltage is nearly constant across the rated
peak pulse current range due to the extremely low ON
Resistance of the FET.
TDS3311P is designed to protect voltage bus or data
lines with an operating voltage as high as 33V. It is rated
for a high-energy transient current up to 35A
(tp = 8/20us) and may be used to meet the common
industrial voltage surge standard of ±1kV (RS = 42Ω,
CS= 0.5μF) .
TDS3311P is in a small DFN 1.6mm x 1.6mm x 0.55mm
6- Lead package and represents significant board space
savings over traditional solutions.
