Littelfuse TVS SPA Diode Arrays
Littelfuse TVS SPA Diode Arrays are protection devices designed to suppress electrostatic discharge, electrical fast transients, and surge events across communication, power, and portable electronic interfaces. The devices are built on silicon avalanche technology and emphasize low clamping performance, low leakage, and strong immunity to repetitive transient stress in compact surface-mount packages.
Three devices target different protection needs. The SC712-02HTG is optimized for RS-485 and other asymmetrical-voltage communication interfaces with working voltages from -7V to +12V and 20A surge tolerance. The SC3000-01UTG is aimed at higher-voltage protection, including USB PD 3.1 VBUS circuits, with 30V reverse standoff voltage and 100A surge handling. The SC1003-01ETG is a compact single-line TVS device for portable and space-constrained electronics, with 5V working voltage and a tiny SOD882 package.
The Littelfuse TVS SPA Diode Arrays are ideal for communication equipment, fieldbus networks, USB charging rails, digital cameras, mobile devices, and medical or navigation systems that require robust transient protection. Across the devices, Littelfuse supplies options ranging from portable low-voltage line protection to industrial and higher-current surge suppression.
