Product details
Overview
D7V9H1U2LP1610-7 from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. 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 channel capacitance, and ±30 kV IEC 61000-4-2 contact/air ESD rating - deployed in cellular handsets and USB interfaces.
For engineers reviewing the D7V9H1U2LP1610-7 datasheet, D7V9H1U2LP1610-7 pinout, D7V9H1U2LP1610-7 application, or D7V9H1U2LP1610-7 equivalent, key selection criteria include clamping voltage at 100 A (13.5 V), low leakage (<1 µA at 7.9 V), U-DFN1610-2 (Type B) package compatibility, thermal resistance (417 °C/W), and RoHS/Halogen-free compliance for space-constrained PCB layouts.
Technical Context
This TVS diode operates in unidirectional configuration to clamp positive transients only, with a defined reverse standoff threshold (7.9 V) below which leakage remains under 1 µA. Its silicon avalanche structure enables fast response (<1 ns) to ESD events while maintaining low dynamic impedance during clamping.
The device is optimized for signal integrity in high-frequency interfaces: its 700 pF input capacitance is measured I/O-to-GND at 0 V and 1 MHz, and its 13.5 V clamping voltage at 100 A ensures safe voltage limiting for 3.3 V and 5 V logic rails during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 7.9 V - Maximum continuous DC voltage before significant leakage begins; sets operating margin for 3.3 V/5 V I/O lines. |
| Breakdown Voltage (Min) | 8.2 V - Avalanche conduction initiates reliably at ≥8.2 V, ensuring predictable turn-on during overvoltage. |
| Clamping Voltage (100 A) | 13.5 V - Limits transient voltage to ≤13.5 V during 8/20 µs surge, protecting downstream ICs with 15 V abs max ratings. |
| Peak Pulse Current | 100 A - Withstands IEC 61000-4-5 Level 3 (1 kV) surges when used with proper PCB layout and trace inductance. |
| Channel Capacitance | 700 pF - Measured I/O-to-GND at 0 V/1 MHz; suitable for USB 2.0 (480 Mbps) but not USB 3.0 or HDMI. |
| ESD Rating | ±30 kV - Complies with IEC 61000-4-2 Contact and Air discharge, exceeding industrial immunity requirements. |
| Thermal Resistance | 417 °C/W - Junction-to-ambient value on FR-4 with recommended 2 oz copper pad; dictates power derating above 25 °C. |
Pinout & Package
Package: U-DFN1610-2 (Type B), 1.6 mm × 1.0 mm × 0.5 mm, 2-terminal surface-mount device with NiPdAu-plated copper leadframe and UL 94V-0 green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line; conducts during positive transients to shunt current to ground. |
| Pin 2 | Cathode | Connected to system ground (GND); provides return path for ESD current; polarity defines unidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD Protection | ±30 kV contact/air - Eliminates need for external ESD test fixtures during system qualification. |
| Low Input Capacitance | 700 pF - Minimizes signal distortion on high-speed digital lines such as USB D+/D− or audio codecs. |
| Lead-Free & Green Construction | Halogen- and antimony-free, <900 ppm Br/Cl, <1000 ppm Sb - Meets IPC-1752A Class 2 reporting and automotive PPAP requirements. |
| Moisture Sensitivity Level | MSL 1 - No bake requirement prior to reflow; supports standard SMT assembly without floor-life constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | DO-214AC package (4.5 mm × 2.7 mm), 7.5 V standoff, 100 A IPP, 1000 pF CT | Higher capacitance and larger footprint; suited for board-level primary protection, not fine-pitch data lines | Select for cost-sensitive industrial PCBs where 1.6 × 1.0 mm U-DFN is not required |
| SP1003-01UTG | SOD-323 package (1.7 mm × 1.3 mm), 7 V standoff, 30 A IPP, 12 pF CT | Lower clamping (11.2 V @ 30 A) and ultra-low capacitance; rated only for IEC 61000-4-2 ±20 kV | Select for USB 3.0 or MIPI D-PHY where sub-15 pF loading is mandatory |
Compared with SMAJ7.5A and SP1003-01UTG, D7V9H1U2LP1610-7 uniquely balances compact U-DFN1610-2 size, 700 pF capacitance, and full ±30 kV ESD rating - making it optimal for space-constrained, high-reliability USB 2.0 and smartphone interface designs.

FAQ
What is the maximum clamping voltage at 50 A for D7V9H1U2LP1610-7?
The clamping voltage is 11 V at 50 A peak pulse current (8/20 µs waveform), measured from I/O to GND. This value ensures safe voltage limiting for 5 V logic systems during mid-level surge events and is specified in the Electrical Characteristics table of DS40603 Rev. 1–2, page 2.
Can D7V9H1U2LP1610-7 be used for bidirectional ESD protection?
No - D7V9H1U2LP1610-7 is a unidirectional TVS diode with anode and cathode terminals; it only clamps positive transients. For bidirectional protection, a dedicated symmetric device like D7V9H1B2LP1610-7 (same package, dual-channel, ±7.9 V) is required per Diodes' documentation.
What is the recommended PCB pad layout for optimal thermal and electrical performance?
Diodes specifies a FR-4 pad layout with 2 oz copper, matching the U-DFN1610-2 (Type B) outline dimensions (1.6 mm × 1.0 mm). The recommended land pattern includes solder mask defined pads and thermal vias under the exposed pad (if present); full details are published at diodes.com/package-outlines.html.
Does D7V9H1U2LP1610-7 meet AEC-Q200 stress testing requirements?
No - this part is not qualified to AEC-Q200. It is rated for industrial temperature range (–55 °C to +150 °C) and MSL 1 handling, but Diodes does not list it in their AEC-Q200 qualified portfolio. Automotive-grade equivalents require explicit AEC-Q200 certification noted in the ordering part number and datasheet header.
