Product Attributes

Introduction

The CD143A-SR05 and CD143A-SR12 devices provides ESD, EFT and surge 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 mmx1.20 mm and is available in a SOT-143 package intended to be mounted directly onto an FR4 printed circuit board. The device will meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5 (Surge) requirements.
