Product details
Overview
PTVS12VZ1USK from Nexperia is a unidirectional transient voltage suppressor (TVS) diode in a DSN1608-2 (SOD964) leadless package, designed for ESD and surge protection of low-voltage DC power rails and signal lines in space-constrained mobile electronics. It delivers 1900 W peak pulse power (8/20 µs), clamps at 24.9 V under 65 A surge, and exhibits 0.11 Ω dynamic resistance with only 0.29 mm height.
For engineers reviewing the PTVS12VZ1USK datasheet, PTVS12VZ1USK pinout, PTVS12VZ1USK application, or PTVS12VZ1USK equivalent, key selection criteria include its 12 V reverse standoff voltage, sub-0.2 µA leakage at 12 V, 430 pF capacitance at 0 V, IEC 61000-4-2 ±30 kV ESD rating, and compatibility with automated reflow soldering on ultra-thin PCBs.
Technical Context
This TVS operates as a unidirectional clamping device-conducting only during positive transients relative to cathode (Pin 1), making it suitable for protecting grounded supply rails or single-polarity signal paths. Its breakdown voltage is 13.3–15.4 V at 10 mA, and clamping voltage is specified at both 8/20 µs (24.9 V @ 65 A) and 10/1000 µs (18–21.8 V @ 10.5 A) waveforms per IEC standards.
The DSN1608-2 package enables direct integration into high-density mobile PCB layouts, with thermal performance validated up to 150 °C junction temperature and storage stability from −65 °C to +150 °C. Its 430 pF capacitance and low dynamic resistance support fast response without compromising signal integrity on 1–10 MHz interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V reverse standoff voltage - maintains <0.1 nA leakage below system operating voltage, avoiding false triggering on nominal 12 V rails. |
| VBR | 13.3–15.4 V breakdown voltage at 10 mA - defines precise conduction onset for overvoltage events above normal operation. |
| VCL (8/20 µs) | 24.9 V clamping voltage at 65 A - limits downstream IC stress to safe levels during lightning or inductive-spike surges. |
| Rdyn | 0.11 Ω dynamic resistance - ensures minimal voltage overshoot during fast transients by reducing IR drop across the diode. |
| Cd | 430 pF diode capacitance at 1 MHz / 0 V - compatible with USB 2.0, I²C, and low-speed serial buses without signal degradation. |
| ESD Rating | ±30 kV contact discharge per IEC 61000-4-2 - provides robust immunity against human-body-model ESD in handheld devices. |
| Package | DSN1608-2 (SOD964), 1.6 × 0.8 × 0.29 mm - enables placement in tight spaces such as smartphone camera modules or battery management circuits. |
Pinout & Package
PTVS12VZ1USK uses a 2-terminal DSN1608-2 (SOD964) surface-mount package with a marking bar indicating the cathode. The package has no leads, relies on solder joint thermal conduction, and is optimized for high-volume reflow assembly with a 0.6 mm pitch and 0.29 mm profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., VBUS); conducts when line voltage exceeds VRWM + VBR relative to ground. |
| 2 (A) | Anode | Connected to ground reference; completes current path during transient clamping, requiring low-inductance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.29 mm height - fits beneath stacked components and supports ultra-thin mobile form factors (e.g., foldable displays). |
| High surge capability | 1900 W peak pulse power (8/20 µs) - withstands repeated industrial-grade surges without degradation. |
| Low dynamic resistance | 0.11 Ω - minimizes clamping voltage rise during high-current transients, improving protection margin for downstream ICs. |
| Sub-nA leakage | 0.1 nA typical reverse current at 12 V - eliminates standby power loss in battery-powered IoT sensors and wearables. |
| Automated assembly ready | SOD964 footprint with defined reflow pad layout - ensures reliable solder joint formation in high-speed SMT lines without tombstoning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | DO-214AC package (4.5 × 2.7 × 2.2 mm), 200 W PPPM, 12.2 V VRWM, 19.9 V VCL @ 10.5 A | Higher profile and lower surge rating - suited for board-level protection where space is less constrained. | Select when higher mechanical robustness and legacy footprint compatibility outweigh size and surge requirements. |
| TPSMF12A | SOD-123FL package (2.7 × 1.7 × 1.0 mm), 200 W PPPM, 12 V VRWM, 19.9 V VCL @ 10.5 A, 500 pF Cd | Larger footprint and higher capacitance - acceptable for non-high-speed analog/sensor lines but not USB or RF paths. | Choose for cost-sensitive industrial designs where 0.29 mm height is not mandatory and 500 pF capacitance is tolerable. |
Compared with SMAJ12A and TPSMF12A, PTVS12VZ1USK offers 9.5× higher peak pulse power in 1/15th the volume and 43% lower capacitance-making it uniquely suitable for next-generation compact, high-reliability mobile power protection where board area and signal fidelity are critical.

FAQ
What is the maximum clamping voltage of PTVS12VZ1USK under an 8/20 µs surge?
The maximum clamping voltage is 24.9 V at 65 A peak pulse current under IEC 61000-4-5 8/20 µs waveform conditions. This value is measured from Pin 1 (cathode) to Pin 2 (anode) at 25 °C ambient and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can PTVS12VZ1USK be used for bidirectional protection?
No-PTVS12VZ1USK is a unidirectional TVS diode, conducting only when the cathode (Pin 1) is driven positive relative to the anode (Pin 2). For bidirectional protection, a separate device such as PTVS12VU1USK (bidirectional variant) or back-to-back configuration is required.
What is the recommended PCB footprint for DSN1608-2 reflow soldering?
The official Nexperia reflow footprint specifies a 0.885 mm × 0.93 mm solder paste stencil opening, 1.8 mm × 2.0 mm solder resist window, and 0.7 mm × 1.2 mm copper land pattern with 0.075 mm radius corners. This layout prevents solder bridging and ensures full wetting of both terminals during standard lead-free reflow profiles.
How does PTVS12VZ1USK perform at elevated temperatures?
At 125 °C ambient, its reverse leakage current increases to ≤200 nA (vs. 0.1 nA at 25 °C), and rated peak pulse power derates to ~70% of the 25 °C value (1330 W). Junction temperature must remain ≤150 °C during surge events, requiring adequate PCB copper area for thermal dissipation in continuous high-temp environments.
