General Port Protection Solutions

Littelfuse General Port Protection provides a wide array of solutions for power and communication ports. Ports need protection from common electrical hazards such as lightning surges, induced power surges, power cross, electrical fast transient, electrostatic discharge, and short-circuits due to aging wires or installation errors. Littelfuse General Port Protection products are ideal for automotive, building automation, consumer electronics, and industrial applications.

ESD Protection Solutions

Littelfuse provides a wide range of products that protect components from ESD threats. ESD threats are extremely fast, low-energy events that can wreak havoc on electronic equipment. Trends in reduced chip protection and harsher end-user environments are requiring the need for enhanced protection solutions. Littelfuse produces varistors, suppressors, indicators, and more so users can find the right protection to ensure the long-term reliable operation of applications.

General-Purpose ESD Protection SPA Diodes

Littelfuse General-Purpose ESD Protection SPA Diodes protect electronics from transient voltage damage. The wide selection offers diodes that meet industry requirements to solve multiple exposure issues. Typical applications for Littelfuse General-Purpose ESD Protection SPA Diodes include 10/100/1000 Ethernet, DC powerlines, and general I/O.

Smart Thermostat Solutions

Littelfuse Smart Thermostat Solutions components allow designers to implement Internet of Things (IoT) solutions to boost energy efficiency and monitor energy usage. Littelfuse Smart Thermostat solutions complement other Smart Building features, including safety and security systems.

TVS Silicon Protection Arrays (SPA)

Littelfuse Silicon Protection Array (SPA®) TVS Diodes are designed to protect electronics from very fast and damaging voltage transients, such as lightning and electrostatic discharge (ESD). These diodes offer an ideal protection solution for I/O interfaces and digital and analog signal lines in computer and consumer portable electronics. Littelfuse TVS diodes offer a broader application use and improved impulse protection performance over conventional diodes.

Littelfuse High Reliability TVS Diodes

RS-485 ESD, Lightning, & Power Fault Protection

Littelfuse RS-485 ESD, Lightning, and Power Fault Protection feature polymeric positive temperature coefficients (PPTCs) that can protect against short circuit and power crosses. The RS-485 product line includes the resettable PPTCs, TVS diodes, GDTs, and SIDACtor series. The TVS Diode Arrays and SM712 series are specifically designed to protect RS-485 applications from ESD, EFT, and lightning-induced surges. When lightning occurs, the SIDACtor will react by causing voltage to increase across PPTC until GDT fires. 

SM712 600W Asymmetrical TVS Diode Array

Littelfuse SM712 600W Asymmetrical TVS Diode Array is designed to protect RS-485 applications with asymmetrical working voltages (-7V to 12V) from damage due to electrostatic discharge (ESD), lightning-induced surges, and electrical fast transients (EFT). The SM712 absorbs repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standards without performance degradation. It safely dissipates up to 19A of 8/20us induced surge current (IEC-61000-4-5) with very low clamping voltages. Littelfuse SM712 600W Asymmetrical TVS Diode Array is AEC-Q101 qualified, lead free, and RoHS compliant.
