Product details
Overview
D40V0S1U2LP1610-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for board-level transient voltage suppression in low-capacitance signal lines. It features a 40 V reverse standoff voltage, 73 V max clamping voltage at 13 A peak pulse current, ±30 kV IEC 61000-4-2 ESD protection, and 143 pF channel input capacitance - optimized for USB voltage bus and proximity sensor protection in space-constrained portable electronics.
For engineers reviewing the D40V0S1U2LP1610-7 datasheet, D40V0S1U2LP1610-7 pinout, D40V0S1U2LP1610-7 application, or D40V0S1U2LP1610-7 equivalent, key selection criteria include clamping voltage margin vs. IC VDD, I/O line capacitance impact on signal integrity, surge current derating at elevated ambient temperature, and U-DFN1610-2 (Type B) PCB layout compatibility.
Technical Context
This device operates as a unidirectional avalanche breakdown TVS, with cathode-anode conduction during positive transients relative to ground. Its low 143 pF capacitance minimizes signal distortion on high-speed digital lines such as USB 2.0 data pairs, while the 73 V clamping voltage ensures safe voltage limiting for 3.3 V or 5 V rail-protected circuits.
The U-DFN1610-2 (Type B) package integrates a single diode junction between two terminals, with Pin 1 designated as cathode and Pin 2 as anode per schematic and mechanical outline. Thermal performance is characterized by 417 °C/W junction-to-ambient resistance on standard FR-4 with 2 oz copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 40 V - Maximum continuous DC or RMS operating voltage before significant leakage begins; sets upper limit for protected line voltage. |
| Clamping Voltage @ 13 A | 73 V - Peak voltage across device during 8/20 µs lightning surge; determines maximum stress imposed on downstream ICs. |
| ESD Rating (IEC 61000-4-2) | ±30 kV contact / ±30 kV air - Withstands worst-case human-body-model ESD events without degradation; eliminates need for external ESD staging. |
| Channel Input Capacitance | 143 pF - Measured I/O-to-GND at 1 MHz; compatible with USB 2.0 (≤450 pF budget) but not USB 3.x or high-speed MIPI. |
| Peak Pulse Current | 13 A - Maximum non-repetitive surge current (8/20 µs waveform) the device can shunt without failure; defines robustness against lightning-induced surges. |
| Package | U-DFN1610-2 (Type B) - 1.6 mm × 1.0 mm × 0.5 mm footprint with NiPdAu terminals; enables high-density routing and automated reflow assembly. |
Pinout & Package
U-DFN1610-2 (Type B) is a 2-terminal, bottom-terminated, lead-free plastic package with exposed thermal pad (not electrically connected), compliant with JEDEC MO-252 and RoHS 3. Cathode identification is marked by a dot adjacent to Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected signal line; conducts during positive transients to divert surge current to ground (Pin 2). |
| Pin 2 | Anode | Connected to system ground; provides return path for clamped surge current; must be low-inductance ground plane connection. |
Key Features
| Feature | Design Value |
|---|---|
| Single-channel unidirectional topology | Optimized for protecting grounded-signal lines (e.g., USB D+, D− referenced to GND); avoids reverse-bias leakage on floating rails. |
| Low 143 pF input capacitance | Preserves signal edge rate and eye diagram integrity on 480 Mbps USB 2.0 differential pairs without requiring layout compensation. |
| ±30 kV IEC 61000-4-2 ESD immunity | Meets highest industrial and consumer ESD test requirements without additional series resistance or filtering components. |
| Halogen- and antimony-free "Green" construction | Contains <900 ppm Br, <900 ppm Cl (<1500 ppm total Br+Cl), and <1000 ppm Sb - satisfies automotive and EU environmental compliance mandates. |
Applications
| USB Voltage Bus Protection | Battery Protection Circuit |
|---|---|
Use Scenario: Protecting VBUS line in USB Type-A or micro-AB receptacles against hot-plug inrush and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBUS and chassis ground to clamp overvoltage transients before reaching USB controller or power switch. Use Value: Prevents latch-up or oxide damage in 5 V tolerant USB power switches (e.g., TPS2051B) during repeated 100 V/1 A plug/unplug cycles. | Use Scenario: Safeguarding lithium-ion battery monitor ICs (e.g., BQ769x0) from ESD coupling through cell tap connections. IC Role / Device Role / Timing Role: Low-capacitance TVS on individual cell voltage sense lines to suppress ±30 kV contact ESD without distorting millivolt-level voltage measurements. Use Value: Maintains <1 mV measurement error under ESD stress, enabling accurate state-of-charge estimation without recalibration. |
| Digital I/O Line Protection | Proximity Sensor Interface |
Use Scenario: Shielding GPIOs of microcontrollers (e.g., STM32L4) connected to external buttons, LEDs, or sensors exposed to user handling. IC Role / Device Role / Timing Role: Point-of-entry TVS on each I/O line referenced to local ground, placed within 2 mm of connector to minimize inductance. Use Value: Enables direct interface to IEC 61000-4-2 Level 4 (±8 kV contact) without series resistors or ferrites, reducing BOM count by one passive per line. | Use Scenario: Protecting capacitive proximity sensor inputs (e.g., FDC1004) from ESD during finger approach or housing contact. IC Role / Device Role / Timing Role: Low-leakage TVS on analog input channel to prevent sensor saturation or ADC offset shift caused by ESD-induced charge injection. Use Value: Limits post-ESD recovery time to <10 ms, ensuring uninterrupted proximity detection during continuous user interaction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ40A | DO-214AC package (4.5 mm × 2.7 mm); 73.3 V clamping @ 12.3 A; 150 pF typical capacitance | Higher mounting height and larger footprint; unsuitable for ultra-thin mobile PCBs | Select when board space allows larger package and higher surge rating is required |
| TPD4E001DPYR | 4-channel array in X2SON-8; 12 pF per channel; 12 V standoff; 22 V clamping @ 4 A | Lower voltage rating and multi-channel integration; not suitable for 40 V bus protection | Select only for low-voltage, multi-line protection where capacitance <15 pF is mandatory |
Compared with SMAJ40A and TPD4E001DPYR, D40V0S1U2LP1610-7 uniquely balances 40 V standoff, 73 V clamping, and 143 pF in a 1.6 mm × 1.0 mm footprint - making it optimal for single-line, mid-voltage, space-constrained USB or sensor protection where DO-214AC is too large and ultra-low-capacitance arrays lack sufficient voltage rating.

FAQ
What is the polarity configuration of D40V0S1U2LP1610-7?
D40V0S1U2LP1610-7 is a unidirectional TVS diode with cathode (Pin 1) connected to the protected line and anode (Pin 2) tied to ground. It conducts only during positive transients relative to ground, providing precise clamping without reverse leakage on negative excursions. This configuration matches standard USB VBUS and battery sense line grounding schemes.
Can D40V0S1U2LP1610-7 be used on bidirectional data lines like USB D+ and D−?
No - D40V0S1U2LP1610-7 is unidirectional and unsuitable for bidirectional differential signals. For USB 2.0 data lines, a bidirectional TVS such as D3V3M1U2LP1610-7 (3.3 V standoff) or SP1003-01UTG (5.5 V standoff) is required to clamp both positive and negative transients. Using this part on D+/D− would leave negative surges unprotected.
How does ambient temperature affect the 13 A peak pulse current rating?
The 13 A rating applies at +25°C ambient. Derating follows Figure 1 in DS41425: at +85°C, peak pulse current drops to ~75% (≈9.8 A); at +125°C, it falls to ~50% (≈6.5 A). Layout must ensure low thermal resistance to maintain surge capability in thermally dense designs like smartphone mainboards.
Is the U-DFN1610-2 (Type B) package compatible with standard reflow profiles?
Yes - the package supports IPC/JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for standard lead-free reflow profiles (peak 260°C, 60–90 sec above 217°C). NiPdAu terminations ensure reliable solder wetting; recommended stencil aperture is 0.12 mm thick with 100% opening area to accommodate the thermal pad's non-electrical nature.
