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.

Transient Voltage Suppressor (TVS) Diodes

Littelfuse TVS (Transient Voltage Suppression) Diodes are a broad range of circuit protection products designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). Lightning strikes, inductive load switching, and ESD cause electrical over-stresses associated with the transmission on data lines and electronic circuits. Offered in a variety of surface mount and through-hole circuit board mounting formats, the TVS Diode portfolio includes high peak pulse current and peak pulse power options up to 20kA and 30kW, respectively. Littelfuse TVS Diodes are chosen for the fast response time (low clamping voltage), lower capacitance, and low leakage current. TVS Diodes are available in both unidirectional (unipolar) or bidirectional (bipolar) diodes circuit configurations. 

SP3031 TVS Diode Array SPA™

The Littelfuse SP3031 Series features low capacitance rail-to-rail diodes with an additional zener diode to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These Littelfuse SP3031 robust diodes can safely absorb repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard (±10kV contact discharge) without performance degradation. With a low dynamic resistance of 0.6Ω, the SP3031 Series offers superb clamping performance to protect sensitive chipsets. The low loading capacitance of 0.8pF minimizes signal degradation and distortion; making these devices ideal for protecting high-speed signal pins such as USB 2.0, Ethernet, MHL/MIPI/MDDI, Set Top Boxes, Game Consoles, Smart Phones, External Storage, Ultrabooks, NoteBooks, Tablets, eReaders.

Heat Pumps

Littelfuse provides a broad portfolio of components for heat pumps, including fuses, TVS diodes, gate drivers, and more. The heat pump market is growing quickly, driven by government initiatives to reduce greenhouse gas emissions and rising energy costs. With inverter-driven motors improving system efficiencies, heat pumps can now be used in a wide range of climates. Learn how Littelfuse technologies make heat pumps safer, more reliable, and more energy efficient. Heat pumps can be used in a wide range of climates due to the inverter-driven motors improving system efficiencies. These components are suitable for various applications such as energy management, security systems, HVAC systems, smoke detectors, and IoT-controlled appliances. Littelfuse offers protect, control, and sense technologies to improve buildings’ reliability, safety, and energy efficiency.

Ethernet ESD, Lightning, & Power Fault Protection

Littelfuse Ethernet/PoE ESD, EFT, Lightning, and Power Fault Protection ensures that the power fault overcurrent can be protected with Telelink fuses. The Ethernet Power Fault Protection includes the SMCJ and SP40 TVS Diode, SP3, SRV05xx, LC03xx, and SP40xx Diode Array, and the 0461xxx Fuse series. Littelfuse Ethernet/PoE ESD, EFT, Lightning, and Power Fault Protection products meet various applicable standards. 

Low Capacitance ESD SPA Diodes

Littelfuse Low Capacitance ESD SPA Diodes protect cables that operate with high-speed data and signals. These Littelfuse Low Capacitance ESD SPA Diodes include unidirectional and bidirectional devices with a 3.3V to 6V working voltage and 1 to 8 channels.

TVS Silicon Protection Arrays (SPA)

Littelfuse TVS Diode Arrays SPA™ (Silicon Protection Arrays) 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 SPA diodes offer a broader application use and improved impulse protection performance over conventional diodes.
