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.

SP4337 Bidirectional TVS Diode Arrays

Littelfuse SP4337 Bidirectional TVS Diode Arrays are designed to protect high-speed interfaces against electrostatic discharge (ESD), such as HDMI and DisplayPort interfaces, Thunderbolt, and USB 3.1 Gen 1. The signal line of the Littelfuse SP4337 is protected by a TVS diode offering a low line capacitance of 0.18pF (typical). SP4337 safely absorbs repetitive ESD strikes up to ±15kV contact exceeding IEC 61000-4-2, level 4 (±8kV contact discharge). These TVS diodes also provide low capacitance, high clamping capability, low leakage, and fast response times. These features make the SP4337 arrays ideal for protecting high-speed data lines.

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. 

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.

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.
