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.

Ultra Low Capacitance TVS SPA Diodes

Littelfuse Ultra Low Capacitance TVS SPA Diodes provide higher-order ESD protection for challenging high-speed serial interfaces. Littelfuse Ultra Low Capacitance TVS SPA Diodes are ideally suited for 10/100/1000 Ethernet and data line applications.

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. 

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

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.

General Port Protection Solutions

Littelfuse General Port Protection provides a wide array of solutions for power and communication ports. Ports need protection from common electrical hazards such as lightning surges, induced power surges, power cross, electrical fast transient, electrostatic discharge, and short-circuits due to aging wires or installation errors. Littelfuse General Port Protection products are ideal for automotive, building automation, consumer electronics, and industrial applications.

SP3522 0.15pF 22kV Automotive Avalanche Diodes

Littelfuse SP3522 0.15pF 22kV Automotive Avalanche Diodes come in an ultra-small (0201 DFN or SOD882) package and integrate ultra-low capacitance (0.15pF) cathode-to-cathode silicon avalanche diodes for ESD protection. Littelfuse SP3522 safely absorbs repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard (±8kV contact discharge) without performance degradation. The low loading capacitance of the AEC-Q101-qualified SP3522 makes it ideal for protecting high-speed signal pins, sich as V-By-One®, HDMI, USB3.0, USB2.0, and IEEE 1394.
