TPD4E001 ESD Protection Array

Texas Instruments' TPD4E001 is a low-capacitance ±15 kV ESD-protection diode array designed to protect sensitive electronics attached to communication lines. Each channel consists of a pair of diodes that steer ESD current pulses to VCC or GND. The TPD4E001 protects against ESD pulses up to ±15 kV Human-Body Model (HBM), ±8 kV Contact Discharge, and ±15 kV Air-Gap Discharge, as specified in IEC 61000-4-2. This device has a 1.5 pF IO capacitance per channel, making it ideal for use in high-speed data IO interfaces. The ultra low leakage current (<1 nA max) is suitable for precision analog measurements in applications like glucose meters and heart rate monitors.
