Protection ratings and signal-line fit
The D5V0H1U2LP1610-7 is a single-channel Zener TVS diode in a U-DFN1610-2 (Type B) package — essentially a 0603 footprint. It clamps at 11.5V maximum and handles 90A peak pulse current under the 8/20µs waveform, so it's sized for ESD and surge events on low-voltage data lines, not for power rail crowbar protection. Reverse standoff is 5V max, meaning the line sits at 5V or below during normal operation without leakage concerns. Breakdown minimum is 5.5V, giving a tight guard band for 3.3V and 5V logic interfaces.
Capacitance and signal integrity
Capacitance is 800pF measured at 1MHz — high enough to round edges on fast digital buses like USB 2.0 or 100 Mbps Ethernet if placed directly on the line. For sub-MHz signals (I²C, UART, GPIO, sensor analog) the loading is negligible. No power line protection (: No) confirms this part is meant for signal/data lines, not DC bus clamping. The 90A pulse rating under 8/20µs covers IEC 61000-4-5 surge level 2 (line-to-ground) with margin.
The 150°C ceiling is the junction limit; board temperature near the part should stay below 125°C for reliable long-term operation.
