Bidirectional TVS Diode Array with 5A Surge Tolerance Extends Operating Life of Sensitive Consumer Electronics

Littelfuse SP1333-01UTG

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

Littelfuse 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 3.3 V, 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 ±30 kV, safely absorbing repetitive ESD strikes without performance degradation. Low clamping voltages allow the SP1333 Series to tolerate surges >5 A, for extended operating life for the electronics they protect.

Typical applications for SP1333 Series TVS Diode Arrays include:

  • Mobile / smartphones,
  • Portable medical devices,
  • MP3/PMP devices,
  • Portable navigation devices,
  • Small size panels
  • Tablets,
  • Point of sale terminals.

“The SP1333 Series completes our portfolio of TVS Diode Arrays in compact 0201 packages, which now covers the full breakdown voltage range from 3.3 V to 36 V,” said Tim Micun, Business Development Manager, TVS Diode Arrays (SPA Diodes) at Littelfuse. “This addition to the product line improves our service level to the market and makes Littelfuse the protection source of choice for leaders in the electronics market.”

SP1333 Series TVS Diode Arrays offer these key benefits:

  • Low capacitance (just 10 pF per I/O) helps preserve signal integrity and minimizes data losses.
  • Very low (<50 nA) parasitic leakage is optimized to extend operating life.
  • A combination of high (>5 A) surge tolerance and ±30 kV ESD protection for more robust protection against electrical threats.


SP1333 Series TVS Diode Arrays are available in a surface-mount 0201DFN package in tape & reel format in quantities of 15,000. Sample requests may be placed through authorized Littelfuse distributors worldwide.
