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.

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.
