The diodes provide extremely low breakdown/turn-on voltages, making them suitable protectors of high-speed data lines with low voltage (-0.3 to +0.3V). Without performance degradation, they can safely absorb repetitive ESD strikes above the maximum level specified in IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge).The SPxxR6 TVS Diode Arrays are intended for a wide range of data communications interfaces for consumer electronics, including:
- USB 3.2 and 4.0,
- Thunderbolt 3.0 and 4.0,
- PCI Express 6.0.
According to Littelfuse, the chipsets from USB 4.0 suppliers are known to be particularly susceptible to damage from voltages over 3.3V. The SP33R6 and SP00R6 TVS diode array series have been designed to provide increased protection of high-speed interfaces like USB 4.0 against repeated ESD strikes and by using a multiline package footprint (SP33R6) or 0201-package (SP00R6) it is likely already on the circuit board. The company claims that design engineers can expect a ten times lower pass-through voltage when compared with existing solutions currently on the market.
The SPxxR6 offers a number of key benefits:
- Compliant with numerous IEC standards for ESD suppression and lightning surge protection, including IEC 61000-4-2, ±12kV contact, ±15kV air; Surge Tolerance, 3A (8/20μs) IEC 61000-4-5, 2nd Edition.
- Provides four channels with 0.2pF low capacitance per I/O to protect ultra-high-speed interfaces.
- An environmentally friendly component that is halogen-free, lead-free, and RoHS compliant
