Littelfuse launched a series of bidirectional TVS Diode Arrays (SPA Diodes) designed to protect consumer and wearable electronics from damaging ESD-generating events. The SP1333-01UTG, the first TVS Diode Array in the SP1333 Series (with a breakdown voltage 3.3V), incorporates back-to-back diodes fabricated using a silicon avalanche technology. This back-to-back configuration provides symmetrical data line protection from ESDs up to ±30kV, safely absorbing repetitive ESD strikes without performance degradation.
