TVS Diode Arrays Safeguard Consumer Electronics


Ideal for Vbus, portable battery, and button/switch protection in consumer electronics, medical equipment

Littelfuse, Inc. announced a new series of 50 A unidirectional TVS Diode Arrays (SPA Diodes). Compared to solutions currently available on the market, the SP1250-01ETG 50 A unidirectional TVS diode arrays provides superior protection via lower clamping voltage and low leakage current, all in a PCB space-saving footprint.

Typical markets and applications for the SP1250-01ETG include:

  • Consumer electronics – desktops, servers, and notebooks

  • Computer peripherals

  • Medical equipment

  • Point-of-Sale (POS) terminals

  • Test equipment / instrumentation

  • Portable battery

The SP1250 discrete unidirectional TVS diode array is fabricated in a proprietary silicon avalanche technology. These diode arrays provide high ESD (electrostatic discharge) protection for consumer electronic equipment. The SP1250 safely absorbs repetitive ESD strikes of ±30 kV (contact and air discharge as defined in IEC 61000-4-2) without any performance degradation. Each device can dissipate up to 50 A 8/20 μs surge event.

The SP1250-01ETG series TVS diode arrays offer these key benefits:

  • Robust protection against electrical threats due to its high surge capability (50 A, tP=8/20 μs) and low clamping performance (8.7V; TYP, Ipp=50 A).

  • Extended operating life resulting from low leakage current, 0.02 μA (TYP) at 5 V.

  • Easy mounting in small PCB spaces with a compact SOD-882 DFN package (0402 footprint).

  • Highly reliable performance as an AEC-Q101 qualified solution.
