Description

Semtech SurgeSwitch™ 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.

TDS1401P is designed to protect voltage bus or data

lines with an operating voltage as high as 14V. It is rated

for a high-energy transient current up to 22A(tp = 8/20μs)

and may be used to meet the common industrial voltage

surge standard of ±1kV (RS = 42Ω, CS= 0.5μF).

TDS1401P is in a small DFN 1.0mm x 0.6mm x 0.25mm

2-Lead package and represents significant board space

savings over traditional solutions.
