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.

TDS2261P is designed to work on 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 =

8/20us) and may be used to meet the common industrial

voltage surge standard of +/-1kV per IEC61000-4-5 (RS =

42 Ohms, CS= 0.5uF).

TDS2261P is in a small 2.0 x 2.0mm, 6-pin DFN package

making it ideal for use in space constrained applications.
