Silicon ESD (SESD) protection devices help protect electronic circuits against damage from electrostatic discharge (ESD) events. The 0201-sized SESD device’s miniature footprint – measuring 0.6mm x 0.3mm x 0.3mm – is approximately 70 percent smaller than prior-generation devices, offering designers flexibility in space-constrained applications.
