描述 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.

TDS2211P is designed to protect voltage bus or data

lines with an operating voltage as high as 22V. It is rated

for a high-energy transient current up to 40A

(tp = 8/20μs) and may be used to meet the common

industrial voltage surge standard of ±1kV (RS = 42Ω,

CS= 0.5μF).

TDS2211P 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.
