They can safely absorb up to 30A of surge current and a minimum of ±30kV ESD without performance degradation. Their low loading capacitance (3.0pF) and high surge capability make them well-suited for protecting telecommunication ports such as Ethernet and other high-speed data interfaces.
Typical applications for SP4208 series TVS diode arrays include:
- 10/100/1000 Ethernet
- T1/E1/T3/E3
- USB 1.1/2.0, power ports
- Instrumentation
- Medical equipment
- Computers and peripherals.
“The SP4208 series TVS diode arrays combine a standoff voltage of 8V with a low dynamic resistance, which supports those implementations of G.Fast that run at higher voltages,” said Tim Micun Business Development Manager, TVS diode arrays (SPA Diodes) at Littelfuse. “Their ‘flow-through’ design minimises signal distortion, reduces voltage overshoot, and allows for a simpler printed circuit design.”
SP4208 series TVS diode arrays offer these benefits:
- The 8V nominal standoff voltage permits a higher operating voltage, which is an increasingly important consideration for high speed interfaces.
- Low parasitic capacitance (nominally 3.0pF) allows for an appropriate amount of bandwidth to enable high speed Ethernet interfaces.
- Extremely low dynamic resistance (nominally 0.4Ω) helps to ensure the fastest response during an ESD event.
