Hybrid protection module guards valuable consumer electronics from sustained overcurrents and overvoltages

09-01-2019 | Littelfuse | Passives

Littelfuse has launched the first of a series of bidirectional TVS Diode Arrays (SPA Diodes) created to protect high-end consumer and wearable electronics from ESD-generating events. The first TVS Diode Array in the SP1333 Series, the SP1333-01UTG has a breakdown voltage of 3.3V, combines back-to-back diodes fabricated using a proprietary silicon avalanche technology. This back-to-back configuration offers symmetrical data line protection from ESDs up to ±30kV, safely absorbing repeated ESD strikes with no performance degradation. Low clamping voltages enable the series to tolerate surges >5A, for extended operating life for the electronics they protect.

Typical applications include, mobile/smartphones, portable medical devices, MP3/PMP devices, portable navigation devices, small size panels tablets, and 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 3.3V to 36V,” said Tim Micun, business development manager, TVS Diode Arrays (SPA Diodes) at Littelfuse. “This addition to the line simplifies the designer’s job by eliminating the need to source devices for this breakdown voltage from another vendor.”
