CD143A-SR2.8~3.3 - Steering/TVS Diode Array Series

General Information

The Model CD143A-SR2.8 and CD143A-SR3.3 devices provide ESD protection for the

external ports of portable electronic devices such as cell phones, handheld electronics

and personal computers.

GND

The ESD protection provided by the component enables a data port to withstand a

minimum 8 kV Contact / 15 kV Air Discharge per the ESD test method speciﬁed

in IEC 61000-4-2. The device measures 2.80 mm x 1.20 mm and is available in a

SOT-143 package intended to be mounted directly onto an FR4 printed circuit board.

The Bourns device will meet IEC 61000-4-2 (ESD) to 30 kV, IEC 61000-4-4 (EFT) to

40 A and IEC 61000-4-5 (Surge) to 12 A.

**Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br)

and Chlorine (Cl) content is 1500 ppm or less.

Speciﬁcations are subject to change without notice.

The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.

Users should verify actual device performance in their speciﬁc applications.
