Product details
Overview
PTVS10VZ1USK from Nexperia is a unidirectional transient voltage suppressor (TVS) diode in a DSN1608-2 (SOD964) leadless package, designed for ESD and surge protection on low-voltage signal/power lines in space-constrained mobile devices. It delivers 75 A peak pulse current (8/20 µs), clamps at ≤27 V under that stress, features 0.11 Ω dynamic resistance, and maintains only 0.1 nA reverse leakage at 10 V standoff.
For engineers reviewing the PTVS10VZ1USK datasheet, PTVS10VZ1USK pinout, PTVS10VZ1USK application, or PTVS10VZ1USK equivalent, key selection criteria include its 10 V reverse standoff voltage, ultra-low 0.29 mm profile, IEC 61000-4-2 ±30 kV ESD rating, and verified clamping performance across 8/20 µs and 10/1000 µs waveforms.
Technical Context
This unidirectional TVS operates as a clamping device between anode and cathode terminals, triggering conduction when reverse voltage exceeds 11.1 V (typical breakdown). Its low dynamic resistance (0.11 Ω) ensures minimal voltage overshoot during fast transients, while the 500 pF capacitance at 0 V bias supports high-speed data line protection without signal integrity degradation.
The device complies with IEC 61000-4-5 (surge) and IEC 61000-4-2 (ESD) standards, delivering 2000 W peak pulse power (8/20 µs) and sustaining junction temperatures up to 150 °C. Its SOD964 footprint enables placement directly at I/O connectors or IC pins in smartphones, wearables, and portable medical sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 10 V - Maximum continuous operating voltage before clamping begins; sets upper limit for protected line voltage. |
| Breakdown Voltage (VBR) | 11.1–12.9 V @ 10 mA - Confirmed turn-on threshold; ensures reliable activation before downstream IC damage. |
| Clamping Voltage (VCL) | ≤27 V @ 75 A (8/20 µs) - Peak voltage seen by protected circuit during worst-case surge; critical for IC survivability. |
| Peak Pulse Power (PPPM) | 2000 W @ 8/20 µs - Energy-handling capability for lightning-induced surges per IEC 61000-4-5. |
| Dynamic Resistance (Rdyn) | 0.11 Ω - Low impedance during conduction; reduces clamping voltage rise under high di/dt transients. |
| Capacitance (Cd) | 500 pF @ 1 MHz, 0 V - Measured junction capacitance; compatible with USB 2.0 and MIPI D-PHY interfaces. |
| ESD Rating | ±30 kV contact/air discharge per IEC 61000-4-2 - Full system-level ESD immunity without external RC filtering. |
Pinout & Package
DSN1608-2 (SOD964) is a 2-terminal, leadless surface-mount package measuring 1.6 mm × 0.8 mm × 0.29 mm with 0.6 mm pitch and a cathode-marked top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (A) | Anode | Connected to ground reference; completes low-impedance path for transient energy dissipation during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.29 mm height - Enables integration beneath thin bezels and stacked PCB assemblies in modern smartphones. |
| High ESD robustness | ±30 kV IEC 61000-4-2 - Eliminates need for secondary ESD protection stages in consumer port interfaces. |
| Precision clamping | VCL ≤27 V @ 75 A - Matches 3.3 V and 5 V rail tolerances, preventing latch-up or gate oxide rupture in connected ICs. |
| Low leakage | 0.1 nA @ 10 V - Minimizes standby current drain in battery-powered IoT endpoints and wearables. |
| Thermal resilience | 150 °C max junction temperature - Supports operation in thermally dense modules near RF power amplifiers or PMICs. |
Applications
| USB Type-C Port Protection | Smartphone Display Interface |
|---|---|
Use Scenario: Protecting CC, SBU, and VCONN pins of USB Type-C receptacles against hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and chassis ground, activated within nanoseconds of overvoltage onset. Use Value: Maintains signal integrity with 500 pF capacitance while clamping ±8 kV ESD pulses to <13 V (30 ns measurement), preserving USB 3.1 Gen 1 eye diagram margins. |
Use Scenario: Shielding MIPI D-PHY lanes (clock/data pairs) connecting AP to AMOLED display in foldable smartphones. IC Role / Device Role / Timing Role: Line-to-ground TVS on each differential pair, leveraging low Rdyn to minimize skew between complementary signals during transient suppression. Use Value: 0.11 Ω dynamic resistance limits voltage delta across paired traces to <100 mV during 75 A surge, preventing common-mode noise injection into timing-critical video streams. |
| Wireless Earbud Charging Case | Portable Medical Sensor Hub |
Use Scenario: Safeguarding 5 V charging input and Bluetooth antenna feedline from electrostatic discharge during user handling and pocket insertion. IC Role / Device Role / Timing Role: Bidirectional protection achieved via two unidirectional devices (anode-to-ground + cathode-to-ground); this part handles negative transients on VBUS. Use Value: 0.29 mm height allows co-placement with 0201 passives on compact 4-layer flex-rigid PCBs, reducing BOM count versus larger SO-02 packages. |
Use Scenario: Protecting analog front-end inputs (ECG, SpO₂) and BLE radio I/O from ESD during clinical handling and patient contact. IC Role / Device Role / Timing Role: First-line defense on sensor interface traces, absorbing >95% of 15 kV air-discharge energy before it reaches precision amplifier inputs. Use Value: 0.1 nA reverse leakage avoids DC offset errors in sub-µV biomedical signal chains, enabling <1 µV RMS noise floor compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC package (4.5 mm × 2.7 mm × 2.3 mm); 100 A IPPM; 400 W PPPM; 1000 pF capacitance | Targeted at industrial power supplies, not mobile I/O; incompatible with fine-pitch layouts | Select when board space permits larger footprints and higher surge energy (>2000 W) is required. |
| TPD1E10B06DPYR | 0.65 mm × 0.65 mm × 0.35 mm X2SON; 5.5 A IPPM; 120 W PPPM; 0.9 pF capacitance | Optimized for high-speed data lines (USB 3.2, PCIe); insufficient for 8/20 µs surge compliance | Select when protecting GHz-frequency interfaces where sub-1 pF capacitance is mandatory and ESD-only events dominate. |
Compared with SMAJ10A and TPD1E10B06DPYR, PTVS10VZ1USK uniquely balances 2000 W surge capability, 500 pF bandwidth, and 0.29 mm height-making it the only option validated for simultaneous IEC 61000-4-2 and -4-5 compliance in mobile form factors under 8 mm thickness.

FAQ
What is the maximum clamping voltage of PTVS10VZ1USK under IEC 61000-4-5 surge conditions?
The maximum clamping voltage is 27 V when subjected to a 75 A, 8/20 µs current waveform per IEC 61000-4-5. This value is measured across terminals 1 (cathode) and 2 (anode) at 25 °C ambient, and represents the peak voltage imposed on the protected circuit during worst-case surge events.
Can PTVS10VZ1USK be used for bidirectional protection?
No-it is a unidirectional TVS diode, functional only for reverse-biased overvoltage events on the cathode terminal. For bidirectional protection, two PTVS10VZ1USK devices must be placed in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated bidirectional variant like PTVS10VU1USK should be selected.
How does the 0.11 Ω dynamic resistance impact circuit protection performance?
A dynamic resistance of 0.11 Ω minimizes voltage overshoot during fast-rising transients by limiting the IR drop across the diode during conduction. For example, at 75 A peak current, this contributes only 8.25 V to total clamping voltage-enabling tighter overall VCL control and improved safety margin for 3.3 V and 5 V ICs.
Is PTVS10VZ1USK suitable for automotive infotainment USB ports?
No-this device is not AEC-Q200 qualified and lacks automotive-grade qualification documentation. While its electrical specs may appear sufficient, Nexperia explicitly states non-automotive qualification in the legal disclaimers; automotive applications require parts such as PTVS10VZ2USK-Q or equivalent AEC-Q200 certified variants.
