3 Description
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 1.5pF IO capacitance
per channel, making it ideal for use in high-speed
data IO interfaces. The ultra low leakage current
(< 1nA 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 the TPD4E1U06DCKR
and TPD4E1U06DBVR which are p2p compatible
with the TPD4E001DCKR and TPD4E001DBVR.
These devices offer higher IEC protection, lower
capacitance, lower clamping voltage, and eliminate
the input capacitor requirement.
