Unidirectional TVS Diode Array with 50 A High Surge Resistance and Low Clamping Performance for Consumer Electronics Protection Circuits

7 October 2020 - 0 Comments

Littelfuse has come up with a series of 50 A unidirectional TVS Diode Arrays for superior protection via lower clamping voltage and low leakage current. The SP1250-01ETG 50 A unidirectional TVS diode arrays in a PCB space-saving footprint are fabricated in a proprietary silicon avalanche technology and 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 TVS diode arrays offer 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), and highly reliable performance as an AEC-Q101 qualiﬁed solution are the additional benefits of SP1250-01ETG series TVS diode arrays.

From consumer electronics like desktops, servers, and notebooks, computer peripherals, medical equipment, Point-of-Sale (POS) terminals, test equipment/instrumentation, and portable battery, the SP1250-01ETG arrays find applications in many different markets.

As put in by Jia Zhu, Product Manager, TVS Diode Arrays, by incorporating the SP1250 in consumer electronics design can ensure ultra-strong ESD suppression and excellent surge protection for the product’s power lines, even in harsh environments which will provide high reliability and longer operating life for end-users.

The SP1250-01ETG series is available in tape and reel format in quantities of 3,000. Customers can place sample requests through authorized Littelfuse distributors worldwide.
