New SM Series TVS Diode Array from Littelfuse Offers Greater Protection from Surges, ESD than Similar Components

Littelfuse SM

High ESD withstand capability enhances reliability of equipment in the field


Littelfuse, Inc. has introduced a new series of two-channel, general-purpose TVS Diode Arrays (SPA® Diodes) optimized to help circuit designers protect sensitive equipment from damage due to electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges. SM Series TVS Diode Arrays are available in five voltage options: 5 V, 12 V, 15 V, 24 V, 36 V. All voltage options provide very low dynamic resistance for clamping performance superior to similar components. This ensures optimal performance to protect today’s sensitive electronics. SM Series TVS Diode Arrays can absorb repetitive ESD strikes above the maximum level specified in international standards without performance degradation and safely dissipate up to 24 A of induced surge current. They provide robust protection against electrical threats to datacom ports like RS-232, RS-485, RS-422, RS-423, etc., which are commonly used in automation equipment, diagnostic devices, security and alarm systems, printers, test equipment, etc.

Littelfuse - SM Series TVS Diode Arrays
