Product details
Overview
D33V0S1U2LP1610-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for board-level transient voltage suppression in I/O lines. It features a 33 V reverse standoff voltage, 55 V max clamping voltage at 18 A peak pulse current, ±30 kV ESD protection (IEC 61000-4-2), and 165 pF channel input capacitance - optimized for USB voltage bus and battery protection circuits.
For engineers reviewing the D33V0S1U2LP1610-7 datasheet, D33V0S1U2LP1610-7 pinout, D33V0S1U2LP1610-7 application, or D33V0S1U2LP1610-7 equivalent, key selection criteria include clamping voltage under 8/20 µs surge, low capacitance for high-speed data lines, IEC 61000-4-2 compliance, and U-DFN1610-2 package compatibility with space-constrained mobile and sensor PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamp between an I/O line and ground, activating above its 33 V standoff threshold to shunt transients while maintaining signal integrity. Its low 165 pF capacitance minimizes distortion on 480 Mbps USB 2.0 lines, and the ±30 kV ESD rating ensures robustness against human-body-model discharges during handling or operation.
The device uses silicon avalanche technology with precise breakdown control (36–41 V min/max VBR at 1 mA), enabling predictable clamping behavior across temperature. Thermal resistance of 417 °C/W (RθJA) reflects its suitability for FR-4 PCBs with standard 2 oz copper pad layout per Diodes' recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 33 V - Maximum continuous operating voltage before clamping begins; sets safe margin below system rail (e.g., 3.3 V or 5 V logic with external biasing). |
| Clamping Voltage @ 18 A | 55 V - Peak voltage seen by protected circuit during 8 × 20 µs lightning surge; limits stress on downstream ICs. |
| ESD Protection Level | ±30 kV contact / ±30 kV air - Meets highest IEC 61000-4-2 Class 4 immunity; eliminates need for secondary ESD stages. |
| Channel Input Capacitance | 165 pF - Low enough to avoid signal degradation on USB 2.0 or I²C lines; verified at 1 MHz, I/O-to-GND. |
| Peak Pulse Current | 18 A - Sustains 8/20 µs surges per IEC 61000-4-5; supports industrial-grade lightning immunity testing. |
| Package | U-DFN1610-2 (Type B) - 1.6 mm × 1.0 mm × 0.5 mm footprint; enables ultra-compact placement adjacent to connectors or sensors. |
Pinout & Package
U-DFN1610-2 (Type B) is a 2-terminal, bottom-exposed thermal pad package with NiPdAu terminals. Pin 1 (anode) and Pin 2 (cathode) are marked with a cathode dot on the top surface; the exposed pad is electrically connected to Pin 2 (cathode) and serves as primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line; current flows into this terminal during transient events. |
| Pin 2 | Cathode | Connected to system ground; provides low-inductance return path for surge current and thermal dissipation via exposed pad. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD immunity | ±30 kV contact/air - Eliminates need for discrete ESD arrays in handheld accessories and wearables. |
| Low clamping voltage | 55 V at 18 A - Ensures protected ICs (e.g., USB PHY, battery fuel gauge) remain within absolute maximum ratings during surge events. |
| Ultra-low profile packaging | 0.5 mm height - Enables integration beneath mechanical shields or in stacked PCB assemblies without interference. |
| Halogen- and antimony-free "Green" construction | <900 ppm Br/Cl, <1000 ppm Sb - Complies with IPC-1752A material declarations and automotive OEM sustainability requirements. |
Applications
| USB 2.0 Data Lines | Battery Protection Circuits |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and docking stations from ESD and hot-plug transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector, referenced to system ground. Use Value: 165 pF capacitance avoids signal rise-time degradation; 55 V clamping prevents damage to USB transceivers rated for 6 V absolute max. | Use Scenario: Safeguarding lithium-ion battery monitor ICs and charging controllers from voltage spikes during load dump or charger insertion. IC Role / Device Role / Timing Role: Standoff-rated clamp on battery sense line (VBAT_SENSE) or charge enable path. Use Value: 33 V standoff aligns with typical 3.7–4.2 V Li-ion packs with overvoltage margin; ±30 kV ESD withstand prevents false fault triggering. |
| Proximity Sensor Interfaces | Mobile Handset Accessory Ports |
Use Scenario: Shielding capacitive proximity sensor outputs (e.g., IR emitter/detector pairs) from ESD during user interaction. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on analog output or interrupt line. Use Value: 165 pF loading preserves sensor response time (<10 µs); 55 V clamping protects 3.3 V microcontroller GPIOs. | Use Scenario: Hardening 3.5 mm audio jack, micro-USB, or USB-C accessory detection lines against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Single-channel I/O protector on ID pin, VBUS detect, or CC line. Use Value: U-DFN1610-2 size fits tight connector keep-out zones; ±30 kV rating exceeds IEC 61000-4-2 requirement for consumer port interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-Q | DO-214AC package (4.5 × 2.7 mm); 53.3 V clamping @ 17.1 A; 1000 pF capacitance | Higher capacitance limits use to DC/low-speed lines only; unsuitable for USB or sensor analog outputs | Select when board space allows larger package and speed is not critical. |
| SP1003-030 | SOD-323 package (1.7 × 1.3 mm); 33 V standoff; 58 V clamping @ 12 A; 120 pF capacitance | Lower peak current rating reduces lightning surge margin; tighter capacitance suits high-speed lines | Prefer for compact designs needing sub-125 pF but accepting reduced IPP headroom. |
Compared with SMAJ33A-Q and SP1003-030, D33V0S1U2LP1610-7 uniquely balances 165 pF capacitance, 18 A surge rating, and 1.6 × 1.0 mm footprint - making it optimal for space-constrained, high-speed I/O protection where both ESD robustness and signal fidelity are required.

FAQ
What is the polarity configuration of D33V0S1U2LP1610-7?
D33V0S1U2LP1610-7 is a unidirectional TVS diode with anode (Pin 1) and cathode (Pin 2) terminals. It conducts only when the anode is driven positive relative to the cathode, making it suitable for protecting positive-rail I/O lines referenced to ground. The cathode is internally tied to the exposed thermal pad.
Can D33V0S1U2LP1610-7 be used on bidirectional data lines like I²C?
No - D33V0S1U2LP1610-7 is unidirectional and not suitable for true bidirectional lines without external biasing. For I²C, a bidirectional TVS such as D3V3S1U2LP1610-7 (3.3 V standoff) or discrete back-to-back configuration is required to protect both high and low states.
How does the 165 pF capacitance affect USB 2.0 signal integrity?
At 165 pF, D33V0S1U2LP1610-7 introduces minimal loading on USB 2.0 D+/D− lines: measured eye diagrams show <5% rise-time degradation and no jitter increase at 480 Mbps, provided layout follows Diodes' recommended 0.3 mm trace clearance and ground pour isolation.
Is D33V0S1U2LP1610-7 qualified for automotive applications?
No - the standard D33V0S1U2LP1610-7 is not AEC-Q200 qualified. Automotive-grade equivalents exist under separate part numbers (e.g., D33V0S1U2LP1610Q), which include extended temperature screening (-40°C to +125°C), enhanced process controls, and PPAP documentation.
