Protection specs for a 5.5V rail
The D5V0P1B2LP3-7: That 4A rating at 8/20µs is the standard IEC 61000-4-5 surge waveform — the part handles a 4A surge before the clamping voltage rises to 13V. For a 5V supply line, that means the downstream IC sees no more than 13V during the event.
Capacitance and signal integrity
With 8pF typical capacitance at 1MHz, this diode loads a high-speed data line lightly. For a 100MHz clock or a USB 2.0 differential pair, 8pF per line adds about 1.6pF of differential loading — well within the margin for most PHYs.
Package and placement
Housed in the X3-DFN0603-2 package (0201 metric footprint), this is a two-pin device with the cathode marked by a polarity dot. The 0.60mm x 0.30mm body means it fits in tight filter networks or right at the connector pin. Surface-mount only — no through-hole option. Operating temperature spans -65°C to 150°C junction, covering automotive under-hood and industrial enclosure environments without derating.
