Description
The HSP051-4M5 and HSP053-4M5 are 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.

Features
• Very compact 500 µm pitch package, for easy PCB layout
• Very-large bandwidth: 11.5 GHz (HSP051-4M5), 18 GHz (HSP053-4M5)
• Very-low capacitance: 0.35 pF (HSP051-4M5 - I/O to GND), 0.25 pF
(HSP053-4M5 - I/O to GND)
• Low leakage current: < 1 nA
• 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 (HSP051-4M5, contact discharge)
– ±10 kV (HSP053-4M5, contact discharge)
– ±30 kV (HSP051-4M5, air discharge)
– ±25 kV (HSP053-4M5, air discharge)

Applications
The HSP051-4M5 and HSP053-4M5 are designed to protect against to electro-static
discharge sub-micron technology circuits driving:
• HDMI 2.1, HDMI 2.0 and HDMI 1.4
• USB4, USB 3.2 Gen 2 and Gen 1
• 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), USB4 (20 Gbps) and USB 3.1 Gen 2 (10 Gbps)
