Infotainment & Navigation Solutions

Littelfuse Infotainment and Navigation Solutions protect against ESD, surges, and overcurrents that threaten the advanced electronic ecosystems in vehicles. These ecosystems integrate technologies like Wi-Fi®, BLUETOOTH®, USB data/charging inputs, AUX inputs, telematics, navigation, and more into a graphical user interface on the dashboard. Littelfuse offers a line of SMD PPTCs and fuses, TVS diodes and diode arrays, MLVs, and XTREME-GUARD™ suppressors that keep these robust systems operating as designed.

In-Vehicle Communication Solutions

Littelfuse provides a wide portfolio of fuses, diode arrays, and suppressors suitable for in-vehicle communication applications. The automotive environments are divided into domain architecture and zonal architecture. The domain architecture controls and divides by function, and computation can be performed locally. Zonal architecture environments require a software-based approach, and a central computer is linked to sensors and devices through zonal gateways.

Motor Control Solutions

Littelfuse Motor Control Solutions provide protections that are critical to a vehicle's overall reliability. As mechanical/hydraulic actuators are replaced with electric motors, load dumps, overcurrents, surges, and ESD become potential threats. Littelfuse offers a wide range of TVS Diodes and Diode Arrays, MLVs, MOVs, and PPTCs to protect motor control 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.

Automotive TVS Diodes

Littelfuse AEC-Q101 Qualified TVS Diodes protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. These AEC-Q101 qualified devices offer peak pulse power dissipation ratings of 400W (SZ1SMA) to 3000W (TPSMD). Littelfuse AEC-Q101 Qualified TVS Diodes are ideal for applications such as DC power protection and ESD protection in automotive electronics such as electronic control units, sensors, and entertainment systems, as well as in portable devices that require high reliability. 

AQx AEC-Q101 TVS Diode Arrays

Littelfuse AQx AEC-Q101 TVS Diode Arrays provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These robust diodes can safely absorb repetitive ESD strikes from 7A up to ±30kV (contact discharge, IEC 61000-4-2). These Littelfuse arrays are PPAP capable, single-origin flow from wafer creation through testing, tape, and reel. Littelfuse AQx automotive-grade TVS diode arrays offer durable protection for current and emerging interfaces in the automotive industry.

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

Automotive Qualified SPA TVS Diodes

Littelfuse Automotive Qualified SPA TVS Diodes are capable of production part approval processes (PPAP) with a single origin flow from wafer creation and testing to tape and reel. These AEC-Q101 qualified diodes offer durable protection for current and emerging automotive technologies. Typical applications for Littelfuse Automotive Qualified SPA TVS Diodes include CAN bus, HSSI Ethernet, DC powerlines, data lines, and general I/O.

Off-Highway Electric Vehicle Solutions

Littelfuse provides a wide range of solutions for off-highway electric vehicles. These electric vehicles share a similar architecture and have a power range from 48V to 400V. Off-highway electric vehicles include electric forklifts, golf carts, three-wheelers, tow tractors, compactors, and excavators.

AQ TVS Diode Arrays

Littelfuse AQ TVS Diode Arrays are designed to replace multilayer varistors (MLVs) in electronic equipment for low-speed and DC applications. The 450W discrete unidirectional TVS diodes will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The Littelfuse AQ series can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 30A (AQ05) of 8/20μs induced surge current (IEC 61000-4-5) with very low clamping voltages. AQ TVS diode arrays are AEC-Q101 qualified.
