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.

TDS4501P is designed to protect voltage bus or data

lines with an operating voltage as high as 45V (24VAC).

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 (RS = 42 Ohms,

CS= 0.5μF).

TDS4501P is in a small DFN 1.6 x1.6 x 0.55mm 6- Lead

package and represents significant board space savings

over traditional TVS solutions.
