AEC-Q101 Zener TVS for high-speed signal lines
The D5V0F1U2LPQ-7B: It clamps transients at 12 V while drawing under 1 µA leakage at the 5.5 V standoff voltage — a fit for CAN, LIN, or sensor interfaces that see repetitive ESD events on the assembly line and in the field.
0.5 pF capacitance — signal integrity on fast buses
With 0.5 pF typical capacitance at 1 MHz, this diode loads a high-speed data line less than a standard ESD diode. On a 100 Mbps Ethernet PHY or a USB 2.0 differential pair, that capacitance keeps the signal edge from rounding off — the eye diagram stays open without a redesign of the termination network.
X1-DFN1006-2 — rework-friendly footprint
The X1-DFN1006-2 package (1.0 mm × 0.6 mm, 0.65 mm pitch) is a two-lead DFN with an exposed die attach pad on the bottom. The pad is the cathode — it carries the transient current to the ground plane through a single via under the part. Hot-air rework is straightforward: preheat the board to 150 °C, hit the pad with 300 °C air for 8 seconds, and lift the part without lifting the pad. The package outline is marked with a cathode bar on the top surface, so orientation is clear under a microscope.
Diodes Incorporated lists the D5V0F1U2LPQ-7B as an active product. For new designs, the AEC-Q101 qualification and the 0402 footprint make it a drop-in for automotive-grade ESD protection on space-constrained PCBs.
