Diodes Incorporated D7V9H1U2LP1610Q-7

Overview

D7V9H1U2LP1610Q-7 from Diodes Incorporated is a unidirectional TVS diode designed for board-level ESD and surge protection of single I/O lines in space-constrained applications. It features a 7.9 V reverse standoff voltage, 8.2 V minimum breakdown voltage, 100 A peak pulse current (8/20 µs), 700 pF typical junction capacitance, and ±30 kV IEC 61000-4-2 ESD rating - deployed in mobile device interfaces and touch panels.

For engineers reviewing the D7V9H1U2LP1610Q-7 datasheet, D7V9H1U2LP1610Q-7 pinout, D7V9H1U2LP1610Q-7 application, or D7V9H1U2LP1610Q-7 equivalent, key selection criteria include clamping voltage at 10–13.5 V across 10–100 A surges, low-leakage operation (<1 µA at 7.9 V), AEC-Q101 qualification, and U-DFN1610-2 footprint compatibility with high-density PCB layouts.

Technical Context

This unidirectional TVS diode operates as a clamping device between signal line and ground, triggering conduction above its 8.2 V breakdown threshold to divert transient energy. Its low 700 pF capacitance minimizes signal integrity impact on high-speed lines such as USB 2.0 or I²C interfaces.

The device meets IEC 61000-4-2 (±30 kV contact/air) and IEC 61000-4-5 (lightning surge) standards, with thermal resistance of 417 °C/W and operating temperature range from –55 °C to +150 °C - enabling use in automotive cabin modules and industrial HMI panels where ambient extremes and reliability are critical.

FAQ

What is the maximum clamping voltage of D7V9H1U2LP1610Q-7 at 50 A surge current?

The clamping voltage is 11 V at 50 A peak pulse current (8/20 µs waveform), measured per IEC 61000-4-5 test conditions. This value is specified in the Electrical Characteristics table of DS43464 Rev. 1–2, page 3, and reflects the actual voltage imposed on the protected line during mid-range surge events - critical for verifying margin against downstream IC absolute maximum ratings.

Is D7V9H1U2LP1610Q-7 suitable for bidirectional signal lines like USB D+/D−?

No - D7V9H1U2LP1610Q-7 is a unidirectional TVS diode optimized for single-polarity protection (anode-to-ground configuration). For bidirectional lines such as USB differential pairs, a symmetric bidirectional TVS like D5V0F4U2LP1610Q is required to clamp both positive and negative transients without forward conduction during normal signaling.

Does the U-DFN1610-2 package require special soldering profile or reflow settings?

Yes - the U-DFN1610-2 package has moisture sensitivity level 1 (MSL-1), permitting unlimited floor life, but requires peak reflow temperature ≤260 °C and time above liquidus (TAL) of 60 ±15 seconds per J-STD-020. Diodes recommends using their published pad layout (available at diodes.com/package-outlines.html) to ensure thermal relief and solder joint reliability due to the thermally efficient copper leadframe.

How does the ±30 kV ESD rating translate to real-world handling robustness?

The ±30 kV rating per IEC 61000-4-2 (contact and air discharge) means the device reliably suppresses ESD events exceeding typical human-body-model (HBM) threats (±8 kV–±15 kV) and survives repeated discharges without parameter shift. In practice, this enables >100,000 ESD strikes in production testing and eliminates field failures from operator handling in final assembly or end-user environments.
