Please note that the EMIF01-10005W5 is not only acting
for positive ESD surges but also for negative ones. For
these kind of disturbances it clamps close to ground
voltage as shown in Fig. A5b.
NOTE: DYNAMIC RESISTANCE MEASUREMENT
As the value of the dynamic resistance remains stable for
a surge duration lower than 20
s, the 2.5s rectangular
surge is well adapted. In addition both rise and fall times
are optimized to avoid any parasitic phenomenon during
the measurement of Rd.

The measurements shown here after illustrate very clearly (Fig. A5a) the high efficiency of the ESD protection :
- no influence of the parasitic inductances on Vout stage
- Vout clamping voltage very close to VBR
