The TPD4E001 is a four-channel Transient Voltage Suppressor (TVS) based Electrostatic
Discharge (ESD) protection diode array. The TPD4E001 is rated to dissipate ESD strikes at the
maximum level specified in the IEC 61000-4-2 international standard (Level 4). 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 maximum) is suitable for precision analog measurements in
applications like glucose meters and heart rate monitors.
The TPD4E001 is available in DRL(SOT), DBV (SOT-23), DCK (SC-70), DRS (QFN), and DPK
(PUSON) packages and is specified for –40°C to +85°C operation. See also
TPD4E1U06DCKR and TPD4E1U06DBVR which are p2p compatible with
TPD4E001DCKR and TPD4E001DBVR. These devices offer higher IEC protection, lower capacitance,
lower clamping voltage, and eliminate the input capacitor requirement.
