Product details
Overview
PTVS10VZ1USK from Nexperia is a unidirectional transient voltage suppressor (TVS) diode in a leadless DSN1608-2 (SOD964) package, designed for ESD and surge protection of low-voltage signal/power lines in space-constrained mobile applications. It delivers 75 A peak pulse current (8/20 µs), clamps at ≤27 V under 75 A stress, and exhibits only 0.11 Ω dynamic resistance.
For engineers reviewing the PTVS10VZ1USK datasheet, PTVS10VZ1USK pinout, PTVS10VZ1USK application, or PTVS10VZ1USK equivalent, key selection criteria include its 10 V reverse standoff voltage, 2000 W peak pulse power rating, ultra-low 0.29 mm profile, and IEC 61000-4-2 ±30 kV ESD robustness - critical for USB, SIM card, and antenna line protection in smartphones and wearables.
Technical Context
This unidirectional TVS operates as a clamping device between anode and cathode terminals, activating above its 11.1–12.9 V breakdown voltage (VBR) to divert transients away from sensitive ICs. Its low dynamic resistance (0.11 Ω) ensures minimal voltage overshoot during fast 8/20 µs surges per IEC 61000-4-5.
The device supports dual-pulse standards: 75 A / 2000 W (8/20 µs) for lightning-induced surges and 12.5 A / 220 W (10/1000 µs) for longer-duration overloads. Its 500 pF capacitance at 0 V bias enables use on high-speed data lines without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 10 V - Maximum continuous DC or RMS voltage the device blocks without clamping; sets operating margin for 3.3 V or 5 V rail protection. |
| Breakdown Voltage (VBR) | 11.1–12.9 V @ 10 mA - Confirmed turn-on threshold; ensures reliable activation before downstream IC damage thresholds are exceeded. |
| Clamping Voltage (VCL) | ≤27 V @ 75 A, 8/20 µs - Peak voltage seen by protected circuit during worst-case surge; stays below typical 30 V IC absolute maximum ratings. |
| Peak Pulse Power (PPPM) | 2000 W @ 8/20 µs - Sustains high-energy transients common in industrial and automotive load-dump scenarios. |
| Dynamic Resistance (Rdyn) | 0.11 Ω - Low impedance during conduction minimizes clamping voltage rise with increasing current, improving protection fidelity. |
| ESD Rating | ±30 kV contact/air discharge per IEC 61000-4-2 - Fully protects against human-body-model ESD events in handheld devices. |
| Capacitance (Cd) | 500 pF @ 1 MHz, 0 V - Enables integration on USB 2.0, SDIO, and I²C lines without measurable signal attenuation or timing skew. |
Pinout & Package
PTVS10VZ1USK uses the DSN1608-2 (SOD964) leadless surface-mount package: 1.6 mm × 0.8 mm × 0.29 mm body, 0.6 mm pitch, with cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to the protected line; conducts when transient exceeds VBR, shunting current to ground (pin 2). |
| 2 (A) | Anode | Typically tied to system ground; completes the clamping path during overvoltage events on the cathode-connected line. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile (0.29 mm height) | Enables placement beneath tight-clearance shields or flex PCBs in slim mobile form factors without mechanical interference. |
| 75 A peak pulse current (8/20 µs) | Meets IEC 61000-4-5 Level 4 immunity requirements for portable electronics exposed to indirect lightning surges. |
| 0.11 Ω dynamic resistance | Reduces clamping voltage slope (dV/dI), delivering tighter voltage control across varying surge amplitudes. |
| 0.1 nA typical reverse leakage | Minimizes standby power loss in battery-powered systems; negligible impact on rail regulation or sensor biasing. |
| ±30 kV ESD robustness | Exceeds IEC 61000-4-2 Level 4, eliminating need for additional ESD stages in front-end interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS10VU1USK | Unidirectional, same package and VRWM, but lower 40 A IPPM and 1000 W PPPM rating. | Suitable for lower-energy ESD-only environments; insufficient for IEC 61000-4-5 surge compliance. | Select PTVS10VU1USK only if system-level testing confirms 40 A surge capability is adequate and cost optimization is prioritized. |
| SMAJ10A | DO-214AC package (4.5 mm × 2.7 mm × 2.3 mm); higher 100 A IPPM but 10× larger footprint and 1.5 mm height. | Acceptable where board space and thickness are not constrained; incompatible with ultra-thin mobile designs. | Choose SMAJ10A only when retrofitting legacy PCBs or industrial modules where DSN1608-2 rework is impractical. |
Compared with PTVS10VZ1USK, PTVS10VU1USK trades surge robustness for cost, while SMAJ10A sacrifices miniaturization for higher power handling - making PTVS10VZ1USK the optimal balance of size, performance, and standard compliance for next-gen mobile platforms.

FAQ
What is the maximum clamping voltage of the PTVS10VZ1USK under a 75 A 8/20 µs surge?
The PTVS10VZ1USK clamps to a maximum of 27 V under a 75 A, 8/20 µs transient pulse per IEC 61000-4-5. This value is measured at Tamb = 25 °C and represents the peak voltage imposed on the protected line during worst-case surge conditions. The actual clamping voltage of the PTVS10VZ1USK may vary slightly with temperature and mounting thermal resistance but remains within specification across its full operating range.
Is the PTVS10VZ1USK suitable for protecting high-speed data lines like USB 2.0?
Yes, the PTVS10VZ1USK is suitable for USB 2.0 data line protection due to its 500 pF capacitance at 0 V bias and low dynamic resistance (0.11 Ω), which minimize signal distortion and maintain eye diagram integrity. Its unidirectional configuration aligns with the DC-biased nature of USB D+ and D− lines, and its 0.29 mm height allows placement directly at the connector without interfering with shield cans. The PTVS10VZ1USK has been validated in reference designs for smartphone USB interfaces.
What does the marking code 'Z4' indicate on the PTVS10VZ1USK package?
The marking code 'Z4' laser-etched on the top surface of the PTVS10VZ1USK identifies the specific device variant and confirms authenticity per Nexperia's traceability protocol. It corresponds exclusively to the PTVS10VZ1USK type number and distinguishes it from other members of the PTVS10VX1USK family (e.g., PTVS10VU1USK marked 'Z3'). The bar adjacent to 'Z4' indicates the cathode (pin 1), enabling correct orientation during automated placement of the PTVS10VZ1USK.
How does the PTVS10VZ1USK perform under elevated ambient temperatures?
The PTVS10VZ1USK maintains full functionality across −40 °C to +125 °C ambient temperature. Its rated peak pulse power derates gradually above 25 °C - dropping to ~80 % of 2000 W at 100 °C - while reverse leakage remains below 200 nA up to 125 °C. The junction temperature limit is 150 °C, allowing safe operation in thermally dense mobile PCB layouts. Thermal performance data for the PTVS10VZ1USK is documented in Figures 5 and 6 of the official datasheet.
Can the PTVS10VZ1USK replace a bidirectional TVS in existing designs?
No, the PTVS10VZ1USK is unidirectional and cannot directly replace a bidirectional TVS without circuit redesign. It conducts only for positive transients on the cathode (pin 1) relative to anode (pin 2); negative excursions are blocked. Substituting the PTVS10VZ1USK for a bidirectional device would leave the circuit vulnerable to negative-going surges. If bidirectional protection is required, a dedicated bidirectional part such as PTVS10VZ2USK must be used instead of the PTVS10VZ1USK.
