AN315 ROBUST ELECTRICAL SURGE IMMUNITY

of Si3400 Protection Si3400 and Si3401 protection consists of a stack of ten, high-current 6.2 V Zener diodes. These lower-voltage Zener diodes have a lower temperature and process variation than a higher voltage Zener clamp, such as an SMAJ58A. Consequently, the range of initial breakdown for the c.

Introduction The Si3400 and Si3401 Power over Ethernet (PoE) powered device (PD) controllers are designed in an efficient Silicon on Insulator (SOI) process technology, which enables the integration of a robust surge protection function. Competitive PoE PD devices require external transient voltage suppressors (TVS), such as an SMAJ58A, to provide surge protection. However, due to the.
