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.

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.

Littelfuse High Reliability TVS Diodes

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.

SP4044/SP4045 TVS SPA Diode Arrays

Littelfuse SP4044 and SP4045 Series TVS SPA Diode Arrays protect sensitive electronics from destructive electrostatic discharges (ESD) and lightning-induced surge events. Low capacitance diodes help to maintain signal integrity and minimize data loss and are integrated with an additional zener diode to protect each I/O pin against ESD and high surge events. These robust devices offer a benchmark-setting surge protection/capacitance ratio, safely absorbing up to 24A of lightning-induced surges while presenting only 1.5pF per I/O-to-Ground connection. This helps to ensure minimal signal degradation. The array can also handle a minimum of ±30kV ESD, so electronics manufacturers can realize greater protection and enhance product reliability in the field. The low loading capacitance also makes the Littelfuse SP4044 and SP4045 series ideal for protecting high-speed signal pins. "Straight-through" routing allows these components to sit on top of the lines the diodes protect, eliminating stub parasitic capacitance and inductance and ensuring higher signal integrity.
