TPD1E0B04 Evaluation Module

Figure 2. System Level ESD Test Setup

3.1.2

Evaluation of Test Results

Connect the tested device on the EVM to a curve tracer both before and after ESD testing. After each
incremental level, if the IV-curve of the ESD protection diode shifts ±0.1 V, or leakage current increases by
a factor of ten, then the device is permanently damaged by ESD.

3.2

Scattering Parameters

A TPD1E0B04 (D6) is configured with 2 SMA (J1 and J2) connectors to allow 2-port analysis with a vector
network analyzer. Connect Port 1 to J1 and Port 2 to J2. This configuration allows for the following
terminology in 2-port analysis:

S

11

: Return loss

S

21

: Insertion loss

±8-kV ESD Clamping Waveforms

A TPD1E0B04 (D6) has two SMA connectors (J1 and J2) which can be used for capturing clamping
waveforms with an oscilloscope during an ESD strike. Caution must be taken when capturing clamping
waveforms during an ESD event so as not to damage the oscilloscope. The procedures in

Section 3.3.1

outlines a proper method.
