General Description

BCD ITVS (Integrated Transient Voltage Suppression)

devices are designed and built using a BCD

proprietary

process

based

on

BCD

standard

technology. These devices integrate the various diodes,

transistors and resistors required to build these ITVS

products. These diodes and transistors feature low

parasitic resistance and the diodes also exhibit low

capacitance. Using these devices, BCD is able to

design

voltage

clamping

products

where

low

capacitance associated with low dynamic resistance is

required.

The BCD AT2140 is a general purpose, high

performance

and

low

cost

device

suitable

for

protecting high speed data interfaces. The AT2140 is a

unique design integrating low capacitance steering

diodes and a clamping cell with associated blocking

diodes,

specially

created

to

protect

sensitive

components connected to data transmission lines.

The AT2140 is available in SOT-23-6 package. This

package allows simple and optimal placement in

existing high-speed PCB layout.
