The CD143A-SR2.8 and CD143A-SR3.3 devices provides ESD

protection for the external ports of portable electronic devices such

as cell phones, handheld electronics and personal computers.

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), IEC 61000-4-4

(EFT) and IEC 61000-4-5 (Surge) requirements.
