Automotive ESD clamp for high-speed data lines
The D5V0S1U2LP-7B: AEC-Q101 qualification and the -65°C to 150°C junction temperature range make it suitable for under-hood or engine-adjacent electronics where the ambient temperature cycles past 85°C. Reverse standoff of 5.5V (max) protects 3.3V and 5V signal rails, while the 210pF capacitance at 1MHz keeps signal integrity on HDMI and USB differential pairs — the capacitance is low enough to avoid distorting edge rates on 480 Mbps USB 2.0 or 1080p HDMI TMDS lines.
Production status and BOM-fit considerations
The 0402 footprint and X1-DFN1006-2 supplier device package are common to many Diodes Inc TVS parts; the base product number D5V0S1 allows parametric cross-referencing within the family for alternate capacitance or clamping voltage grades if the BOM requires a tighter clamp. Power line protection is marked as 'No' — this part is designed for signal-line ESD clamping, not for sustained overvoltage on power rails; use it on data interfaces where the transient energy is limited to IEC 61000-4-2 ESD pulses.
