Littelfuse's SP3422 integrates 4 channels of ultra-low capacitance rail-to-rail diodes and an additional Zener diode to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). This robust component can safely absorb repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard (+8 kV contact discharge) without performance degradation. The extremely low loading capacitance also makes it ideal for protecting high speed signal pins such as V-by-One®, USB3.0, USB2.0, and IEEE 1394.
SPA® Family of TVS Diode Arrays
ESD Protection using TVS Diode Arrays Design Guide
| Features |
|
|
- Increased board space savings when compared to discrete or dual-channel implementations
- Straight-through routing does not degrade signal integrity, eliminates the requirement to “fan out” to make connection to the PCB pins
- Low parasitic capacitance helps to maintain signal integrity, and works on the fastest interfaces of USB3.0, MIPI, and DisplayPort
|
|
- Four lines ESD protection in an outline smaller than conventional SOD-882 package
- Straight-through routing, adjacent lines or connected on opposite sides of the package
- Very low loading capacitance, nominally 0.2 pF, high survivability to ESD
- Automotive grade, MSL-1 product
