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

REF
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.
