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.

Data Center Solutions

Littelfuse Data Center Solutions help make the data center reliable, energy efficient, and safe. These solutions provide overcurrent protection, transient voltage suppression, sensors, and power conversion components needed to keep facilities operating efficiently and reliably. Littelfuse provides Data Center Solutions for computing equipment, networking and data ports, and uninterruptible power supplies.

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.

SP402X TVS Diode Arrays

Littelfuse SP402X TVS Diode Arrays integrate low capacitance steering diodes with one or two zener diodes to provide unidirectional or bidirectional protection against ESD and lightning induced surge events. The device can safely absorb 30A per IEC61000-4-5 (tp=8/20μs) without performance degradation and can withstand a minimum ±30kV ESD per IEC61000-4-2 international standard. The SP402X Series low capacitance of 2.5pF, low leakage current, and small SOD323 package make it ideal for protecting telecommunication ports such as Ethernet and other high speed data interfaces. Typical applications include 10/100/1000 Ethernet, T4/E1/T3/E3, USB 1.1/2.0, power ports, computers and peripherals, instrumentation, and medical equipment.

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. 

Lightning Surge TVS SPA Diodes

Littelfuse Lightning Surge TVS SPA Diodes are designed to limit the amount of unwanted voltages to prevent damage by blocking the surges. Applications for Littelfuse Lightning Surge TVS SPA Diodes include lightning I/O, 10/100/1000 Ethernet, and 2500/5000/10000 Ethernet.

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.
