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.

Electrical Vehicle AC Chargers

Littelfuse provides a wide range of products that are suitable for Electric Vehicle AC Chargers. Although simpler in nature compared to DC chargers, AC charging stations safely deliver AC power from the electrical grid into the vehicle. Due to space and weight constraints in the vehicle, on-board chargers and AC charging stations are typically limited to lower amounts of power (22kW or less), which means charging time is slow – taking several hours. These systems also rely on a vehicle’s on-board charger to enable the conversion of AC power from the grid into DC power to charge the vehicle’s battery. It’s critical that proper measures are taken to safeguard both the charger and vehicle.

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. 

SMAJ TVS 400W Diodes

Littelfuse SMAJ TVS (Transient Voltage Suppression) 400W Diodes are surface-mount diodes designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. These diodes offer 400W peak pulse power capability at 10µs x 1000µs waveform. Littelfuse SMAJ  diodes feature a fast response time, typically less than 1.0ps from 0V to VBR minimum. These diodes are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuits used in telecom, computer, industrial, and consumer electronic applications.

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.

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.

Smart Metering Solutions

Littelfuse Smart Metering Solutions help designers implement more reliable and safer smart meters. Littelfuse solutions for smart meters allow designers to bring Internet of Things technology to the key functions of a smart metering system.

Electrical Vehicle DC Fast Chargers

DC charging stations are designed to convert the electrical grid’s AC power into DC power that can then be fed directly into a vehicle’s battery system for fast charging – in 30 minutes or less. Because the conversion from AC to DC power is being done in the charging station, these units can provide higher levels of power (50kW to 350kW and beyond) to the vehicle compared to AC charging stations. Working with tens to hundreds of kilowatts of power, efficient conversion, reliability of the system, and user safety are critical.

Portable Medical Devices & Connected Drug Delivery

Littelfuse Portable Medical Devices and Connected Drug Delivery Systems feature a range of products ideal for use in wearables, digital hearing aids, insulin pumps, blood pressure monitors, and connected pharmaceutical delivery devices such as auto-injectors and inhalers. Portable and connected devices are changing how medical services are delivered to patients. These connected healthcare products from Littelfuse help lower healthcare costs, improve efficiency, and empower patients.
