| Circuit Protection | 1 | Active | The SPxx-01WTG-C-HV is designed to improve ESD protection in portable applications, LED backlighting modules, and low speed I/Os. It will protect sensitive equipment from damage due to electrostatic discharge (ESD) and other overvoltage transients. The SPxx-01WTG-C-HV can safely absorb repetitive ESD strikes above the maximum level of the IEC61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation and safely dissipate up to 8A (SP12-01WTG-C-HV) of induced surge current (IEC61000-4-5, tP=8/20μs) with very low clamping voltages. |
| Circuit Protection | 1 | Active | The SP2502LBTG provides overvoltage protection for applications such as 10/100/1000 Base-T Ethernet and T3/ E3 interfaces. This device has a low capacitance of only 5pF making it suitable for PHY side Ethernet protection and the capability to protect against both longitudinal and differential transients. Furthermore, the SP2502LBTG is rated up to 100A (tp=2/10μs) making it suitable for line side protection as well against lightning transients as defined by GR-1089 (intra-building), ITU, YD/T, etc. The application schematic provides the connection information for a PHY side protection scheme of a single differential pair. |
| Transient Voltage Suppressors (TVS) | 1 | Active | The SP2504NUTG integrates 4 channels of low capacitance diodes with an additional zener diode to protect sensitive I/O pins against lightning induced surge events and ESD. This robust device can safely absorb up to 20A per IEC 61000-4-5, 2nd edition (tP=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC 61000-4-2 international standard. The low loading capacitance makes the SP2504N ideal for protecting high-speed signal pins. |

| Transient Voltage Suppressors (TVS) | 1 | Active | The SP2555NUTG is a low-capacitance, TVS Diode Array designed to provide protection against ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning induced surges for high speed, differential data lines. It’s packaged in a μDFN package (3.0 x 2.0mm) and each device can protect up 4 channels or 2 differential pairs, up to 45A (IEC 61000- 4- 5 2nd edition,) and up to 30kV ESD (IEC 61000-4-2). The "flow-through" design minimizes signal distortion, reduces voltage overshoot, and provides a simplified PCB design. The SP2555NUTG with its low capacitance and low clamping voltage makes it ideal for high-speed data interfaces such as 1GbE applications found in notebooks, switches, etc. |
| Circuit Protection | 1 | Obsolete | The Littelfuse SP2574NUTG TVS Diode Array (SPA® Diode) protects high-speed, differential data lines from damage due to ESD, CDE, EFT, and lightning-induced surges. It can protect up to four channels or two differential pairs at up to 40A (IEC61000-4-5) and up to 30kV ESD (IEC61000-4-2). Its low capacitance (just 3.8pF TYP from I/O to ground) and low clamping voltage (15 percent lower at 40A than other competitive solutions) make it ideal for protecting high-speed data interfaces. |

| Circuit Protection | 1 | Obsolete | The SP3002 has ultra low capacitance rail-to rail diodes with an additional zener diode fabricated in a proprietary silicon avalanche technology to protect each I/O pin providing a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These robust diodes can safely absorb repetitive ESD strikes at the maximum level (Level 4) specified in the IEC 61000-4-2 international standard without performance degradation. Their very low loading capacitance also makes them ideal for protecting high speed signal pins such as HDMI, DVI, USB2.0, and IEEE 1394. |
