DESCRIPTION/ORDERING INFORMATION

The 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, heart rate monitors, etc. The TPD4E001 is available in DRL, DBV (SOT-23), DCK (SC-70), and DRS (QFN) packages and is specified for –40°C to 85°C operation.
