Fig. A5: Remaining voltage at both stages S1 (Vin1) and S2 (Vout1) during ESD surge

Please note that the EMIF03-SIM01 is not only acting for positive ESD surges but also for negative ones.

For negatives surges, it clamps close to ground voltage as shown in Fig. A5b.

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
