LED Lighting Solutions

Littelfuse LED Lighting Solutions support all facets of the LED lighting market with innovative solutions that not only meet regulatory standards but also increase equipment safety and reliability. To help protect end-users, Littelfuse works closely with many LED driver IC suppliers, to ensure their evaluation boards and reference designs comply with safety and surge immunity requirements. They also assist LED lighting power supply manufacturers in designing optimal protection schemes for their driver modules. At the OEM level, they cooperate with luminaire and lamp manufacturers to ensure their products are optimally designed for robust surge immunity protection.

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.
