General Purpose ESD Protection SPA Diodes

Littlefuse General Purpose ESD Protection SPA Diodes protect electronics from transient voltage damage. The wide selection offers diodes that meet industry requirements to solve multiple exposure issues.

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. 

TVS Silicon Protection Arrays (SPA)

Littelfuse TVS Diode Arrays SPA™ (Silicon Protection Arrays) are designed to protect electronics from very fast and damaging voltage transients, such as lightning and electrostatic discharge (ESD). The diodes offer an ideal protection solution for I/O interfaces and digital and analog signal lines in computer and consumer portable electronics. The TVS SPA diodes offer a broader application use and improved impulse protection performance over conventional diodes.

Industrial Communication & Control

Littelfuse Industrial Communication and Control provides protection for RS-485 and Ethernet applications. The Industrial RS-485 features the capability of driving multiple ports, a fast speed rating of 10Mbps, and a long-distance transmission of 1500. Industrial Ethernet provides a long-distance transmission of 100m, a 30W PoE+ rating, and a fast speed rating of 1Gbps. Littelfuse Industrial Communication and Control RS-485 and Ethernet devices are ideal for energy meters, factory automation, wind control, and human machine interface. 

Littelfuse High Reliability TVS Diodes

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 assure 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 SP4044 and SP4045 Series ideal for protecting high speed signal pins. "Straight-through" routing allows these components to sit on top of the lines they protect, eliminating stub parasitic capacitance and inductance and ensuring higher signal integrity.
