Bi-directional Ultra-low Capacitance ESD / Transient Protection Diode

Summary of Features:

• ESD / transient protection of RF signal lines according to:
– IEC61000-4-2 (ESD): ±25 kV (air/contact)
– IEC61000-4-4 (EFT): 50 A (5/50 ns)
– IEC61000-4-5 (surge): 2.5 A (8/20 μs)
• Maximum working voltage: VRWM ±5.5 V
• Extremely low capacitance: CL = 0.28 pF (typical)
• Low clamping voltage: VCL = 20 V at IPP = 16 A (typical)
• Very low reverse current IR < 1 nA typ.
• Very small form factor down to 0.58 x 0.28 x 0.15 mm3
• Pb-free (RoHS compliant) and halogen free package

Target Applications:

• ESD protection of high-speed signal lines: USB 3.0, DVI, HDMI, S-ATA, DisplayPort, Thunderbolt
• RF antenna protection, frontend module, GPS, mobile TV, FM radio, UWB
