Key Features
- Ultra-low capacitance for minimal signal distortion on high-frequency data lines such as USB and HDMI
- 6.2 V minimum / 7.5 V nominal breakdown voltage for 5 V bus ESD clamping
- 18 V maximum clamping voltage providing robust transient overvoltage suppression per IEC 61000-4-2
- Bi-directional silicon TVS configuration protecting both positive and negative ESD transients
- Compact SOT-23 (MO-236) 2-pin package for space-constrained PCB ESD protection layouts
Applications
The SP3208-01UTG is designed to protect sensitive high-speed data line interfaces — including USB, HDMI, and DisplayPort — from ESD strikes and electrical transients by clamping voltage spikes to 18 V maximum. Its ultra-low capacitance minimizes signal integrity degradation on lines operating at hundreds of megabits per second or multi-gigabit data rates. The compact SOT-23 footprint allows placement close to the protected connector on mobile devices, laptops, and consumer electronics port interfaces.

Frequently Asked Questions
What clamping voltage does SP3208-01UTG achieve during an ESD event and how does this protect downstream ICs?
The SP3208-01UTG clamps transient overvoltages to a maximum of 18 V during high-current ESD pulses. By limiting the peak voltage reaching downstream ICs to 18 V, it prevents gate oxide breakdown in 5 V-tolerant input stages and protects USB or HDMI interface receivers that have absolute maximum input ratings typically in the 6 V to 7 V range under normal operation, with ESD protection cells rated to withstand 18 V peak.
How does the ultra-low capacitance of SP3208-01UTG compare with standard TVS diodes for high-speed USB data lines?
Standard TVS diodes for general-purpose protection often have capacitance values of 100 pF to 500 pF, which would attenuate USB 2.0 (480 Mbps) or USB 3.0 (5 Gbps) signals significantly. The SP3208-01UTG is specified as ultra-low capacitance, typically 0.5 pF to 1 pF, which introduces negligible signal attenuation and preserves eye diagram margin on high-speed differential pairs operating up to several gigahertz.
On a 5 V USB port protection design, why choose SP3208-01UTG's 7.5 V nominal breakdown over a lower-voltage alternative?
A 7.5 V nominal breakdown voltage provides adequate margin above the 5 V bus maximum operating voltage (including tolerance), preventing the TVS from conducting during normal operation while still clamping IEC 61000-4-2 ESD strikes (which can reach 8 kV or 16 A peak current) well before they damage downstream USB controller ICs. A lower breakdown (e.g., 5.5 V) would risk false triggering on 5 V transients within normal operating range, while a higher breakdown would allow excessive clamping voltages to reach sensitive inputs.
