TVS Diode Arrays Provide Ultra-Low Capacitance ESD Protection

Littelfuse’s two series of bidirectional TVS diode arrays are designed to protect ultra-high-speed consumer electronics interfaces from electrostatic discharge (ESD) in applications where PCB layout is especially challenging. The SP3208-01UTG, the first TVS Diode Array in the SP3208 Series, is mechanically optimized to deliver consistently ultra-low capacitance (nominally 0.08 pF). The SP3213-01UTG, the first SP3213 Series device, offers an option for highly cost-conscious ESD protection solutions.

Both devices are AEC-Q101-qualified, employ the same base die, and can absorb repetitive ESD strikes at ±12 kV without performance degradation and dissipate 2A of 8/20 μs surge current. Sub-0.1 pF silicon-based ESD protection allows for passbands as high as 30 GHz, enabling high signal integrity for the fastest data interfaces.

Industry-standard 0201DFN packaging with internal construction enhancements reduce parasitic capacitance, inductance, and resistance, making these TVS Diode Arrays easier to model into a protection scheme. The SP3208 and SP3213 Series TVS diode arrays are available in surface-mount µDFN-2 (0201) packages in tape and reel format in quantities of 15,000. Additional information is available on the SP3213 Series product page and the SP3208 Series product page.
