Features
• Very compact 500 µm pitch package, for easy PCB layout
• Very-large bandwidth: 11.5 GHz
• Very-low capacitance: 0.2 pF (I/O to I/O) and 0.35 pF (I/O to GND)
• Very low dynamic resistance : 0.35 Ω
• Low leakage current: < 1 nA
• High ESD protection level
• High integration
• Suitable for high density boards
• Extended operating junction temperature range : -40 °C to 150 °C
• Exceeds IEC 61400-4-2 level standard:
– ±20 kV (contact discharge)
– ±30 kV (air discharge)
Applications
The HSP051-4M5 is designed to protect against to electro-static discharge sub-
micron technology circuits driving:
• HDMI 2.1, HDMI 2.0 and HDMI 1.4
• USB 3.1 Gen 1 and Gen 2
• Display port
• Digital video interface
• Serial ATA
The ultra-low variation of the capacitance ensures very low influence on signal-skew.
The large bandwidth make it compatible with HDMI 2.1 8K (12 Gbps), HDMI 2.0
4K/2K (5.94 Gbps) and USB 3.1 Gen 2 (10 Gbps).
Description
The HSP051-4M5 is a 4-channel ESD array with a rail to rail architecture designed
specifically for the protection of high speed differential lines.
The device is packaged in μQFN 1.3 mm x 0.8 mm with a 500 μm pitch.
