3 Description
The TPD2E001 is a two-channel Transient Voltage Suppressor (TVS) based Electrostatic Discharge (ESD) protection diode array.
The TPD2E001 is rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 Level 4 international standard.
The DRS package (3.00 mm x 3.00 mm) is also available as a non-magnetic package for medical imaging applications.
See also TPD2E2U06DRLR which is p2p compatible to TPD2E001DRLR and offers higher IEC ESD Protection,
lower clamping voltage, and eliminates the input capacitor requirement.
4.Overview
The TPD2E001 is a two-channel transient voltage suppressor (TVS) based ESD protection diode array.
The TPD2E001 is rated to dissipate ESD strikes at the maximum level specified
in the IEC 61000-4-2 Level 4 international standard.
5. Feature Description
TPD2E001 is a uni-directional ESD protection device with low capacitance.
The device is constructed with a central ESD clamp that features two hiding diodes per line to reduce the capacitive loading.
This central ESD clamp is also connected to VCC to provide protection for the VCC line.
Each IO line is rated to dissipate ESD strikes above the maximum level specified in the IEC 61000-4-2 level 4 international standard.
The TPD2E001's low loading capacitance makes it ideal for protection high-speed signal terminals.
6. Device Functional Modes
TPD2E001 is a passive integrated circuit that activates whenever voltages above VBR
or below the lower diodes Vforward (–0.6V) are present upon the circuit being protected.
During ESD events, voltages as high as ±15 kV can be directed to ground and VCC via the internal diode network.
Once the voltages on the protected lines fall below the trigger voltage of the TPD2E001 (usually within 10s of nanoseconds)
the device reverts back to a high impedance state.
7.Application Information
TPD2E001 is a diode array type Transient Voltage Suppressor (TVS) which is typically used to provide a path
to ground for dissipating ESD events on hi-speed signal lines between a human interface connector and a system.
As the current from ESD passes through the TVS, only a small voltage drop is present across the diode.
This is the voltage presented to the protected IC. The low RDYN of the triggered TVS holds this voltage,
VCLAMP, to a tolerable level to the protected IC.
