Low capacitance solution in 0201 footprint extends breakdown voltage range from 3.3V to 36V


CHICAGO —Littelfuse, Inc. introduced the first of a series of bidirectional TVS Diode Arrays (SPA Diodes) designed to protect high-end 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 proprietary 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. Low clamping voltages allow the SP1333 Series to tolerate surges >5A, for extended operating life for the electronics they protect.

Typical applications forSP1333 Series TVS Diode Arrays include:

  • Mobile / smartphones,

  • portable medical devices,

  • MP3/PMP devices,

  • portable navigation devices,

  • small size panels

  • tablets, and

  • point of sale terminals.

SP1333 Series TVS Diode Arrays offer these key benefits:

  • Low capacitance (just 10pF per I/O) helps preserve signal integrity and minimizes data losses.

  • Very low (<50nA) parasitic leakage is optimized to extend operating life.

  • A combination of high (>5A) surge tolerance and ±30kV ESD protection for more robust protection against electrical threats.
