New TVS diode arrays safeguard consumer electronics

13-10-2020 | Littelfuse | Semiconductors

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

The discrete unidirectional TVS diode array is manufactured in a proprietary silicon avalanche technology. They provide high ESD protection for consumer electronic equipment. The device safely absorbs repetitive ESD strikes of ±30kV (contact and air discharge as defined in IEC 61000-4-2) with no performance degradation. Each device can dissipate up to 50A 8/20μs surge event.

“Incorporating the SP1250 in your consumer electronics design provides ultra-strong ESD suppression and excellent surge protection for the product’s power lines, even in harsh environments,” said Jia Zhu, product manager, TVS Diode Arrays (SPA Diodes). “This design choice will result in both high reliability and longer operating life for end-users.”

Typical markets and applications for the SP1250-01ETG include consumer electronics including desktops, servers, and notebooks; computer peripherals; medical equipment; point-of-sale terminals; test equipment, instrumentation; and portable battery solutions.
