EMIF01-10005W5

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

Fig A5 : Remaining voltage at both stages S1 (Vin) and S2 (Vout) during ESD surge

a) Positive surge

b) Negative surge

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

IPP

As the value of the dynamic resistance remains stable for

a surge duration lower than 20µs, the 2.5µs rectangular

surge is well adapted. In addition both rise and fall times

are optimized to avoid any parasitic phenomenon during

the measurement of Rd.
