The CD143A-SR70 device provides ESD protection for the external
ports of portable electronic devices such as cell phones, handheld
electronics and personal computers. The device also provides EFT
and surge protection.
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.
