Product details
Overview
D3V3S1U2LP1610 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 3.3 V reverse standoff voltage, 3.8 V minimum breakdown voltage, 200 A peak pulse current (8/20 µs), 1400 pF typical channel capacitance, and ±30 kV IEC 61000-4-2 contact/air discharge rating - deployed in USB, SIM card, and audio jack interfaces of smartphones and digital cameras.
For engineers reviewing the D3V3S1U2LP1610 datasheet, D3V3S1U2LP1610 pinout, D3V3S1U2LP1610 application, or D3V3S1U2LP1610 equivalent, key selection criteria include clamping voltage at 200 A (11.5 V), low dynamic resistance (0.03 Ω), thermal resistance (417 °C/W), and U-DFN1610-2 package compatibility with space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamp between I/O and ground, triggering conduction when transient voltage exceeds 3.8 V. Its low 1400 pF input capacitance preserves signal integrity on 10–100 Mbps interfaces, while the 0.03 Ω dynamic resistance ensures rapid energy shunting during ESD events.
The device complies fully with IEC 61000-4-2 Level 4 (±30 kV air/contact) and meets JEDEC JESD22-A114F test conditions. Its U-DFN1610-2 package supports automated placement and reflow soldering per IPC-J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before leakage exceeds 1 µA; sets upper limit for protected line DC bias. |
| Breakdown Voltage (VBR) | 3.8 V min at 1 mA - Ensures reliable turn-on before damage to downstream ICs such as USB transceivers or audio codecs. |
| Clamping Voltage (IPP = 200 A) | 11.5 V - Peak voltage seen by protected circuit during worst-case lightning surge (IEC 61000-4-5); limits stress on 3.3 V logic rails. |
| Channel Capacitance (CT) | 1400 pF at 0 V, 1 MHz - Enables use on low-speed analog/audio lines (e.g., microphone inputs) without signal attenuation or timing skew. |
| Peak Pulse Current | 200 A (8/20 µs) - Withstands multiple high-energy transients without degradation, supporting industrial-grade reliability in handheld devices. |
| Dynamic Resistance | 0.03 Ω - Minimizes voltage overshoot during fast-rising ESD pulses (<1 ns rise time), improving protection margin for sensitive CMOS inputs. |
Pinout & Package
Package: U-DFN1610-2 (Type B), 1.6 mm × 1.0 mm × 0.5 mm, 2-terminal surface-mount, NiPdAu-plated copper leadframe, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line (e.g., USB D+, SIM CLK); conducts transient current toward ground when voltage exceeds VBR. |
| Pin 2 | Cathode | Connected to system ground plane; provides low-inductance return path for surge current; requires solid thermal pad connection per Diodes' recommended layout. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD Rating | ±30 kV contact/air - Exceeds Level 4 immunity requirement, eliminating need for secondary protection stages in consumer handsets. |
| Low Input Capacitance | 1400 pF - Compatible with audio paths and low-speed serial buses where >1 nF capacitance would distort signal edges or attenuate bandwidth. |
| Lead-Free & Green Construction | Halogen- and antimony-free, <900 ppm Br/Cl, <1000 ppm Sb - Meets global environmental compliance mandates (RoHS 3, JEDEC JS709) without performance trade-offs. |
| Thermal Performance | 417 °C/W RθJA on FR-4 - Enables stable operation up to +125 °C ambient when mounted per Diodes' suggested pad layout (2 oz copper). |

FAQ
What is the polarity configuration of D3V3S1U2LP1610?
D3V3S1U2LP1610 is a unidirectional TVS diode with anode (Pin 1) and cathode (Pin 2). It conducts only when the anode voltage exceeds the cathode by ≥3.8 V, making it suitable for protecting positive-rail signals referenced to ground. Its schematic symbol matches standard Zener-like unidirectional clamping behavior.
Can D3V3S1U2LP1610 be used on bidirectional data lines like I²C?
No - D3V3S1U2LP1610 is unidirectional and not rated for reverse-voltage blocking on bidirectional lines. For I²C or other bidirectional interfaces, a bidirectional TVS such as D3V3S1B2LP1610 (same package, symmetrical clamping) is required to protect both high- and low-going transients without forward-conduction leakage.
How does its 1400 pF capacitance affect USB 2.0 signal integrity?
At 1400 pF, D3V3S1U2LP1610 is unsuitable for full-speed (12 Mbps) or high-speed (480 Mbps) USB 2.0 differential pairs, where total capacitance must remain <5–10 pF per line. It is appropriate only for lower-bandwidth applications such as USB enumeration lines, ID pins, or non-high-speed auxiliary signals.
Is thermal pad connection required for reliable operation?
Yes - although the U-DFN1610-2 package lacks an exposed thermal pad, the cathode (Pin 2) serves as the primary thermal path. Diodes' recommended PCB layout specifies a minimum 25 mm² copper pour connected to Pin 2 via ≥4 thermal vias (0.3 mm diameter) to achieve the rated 417 °C/W RθJA and sustain 200 A pulses without junction overheating.
