Product details
Overview
PTVS15VZ1USK 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 power rails and signal lines in space-constrained mobile electronics. It delivers 1900 W peak pulse power (8/20 µs), clamps at ≤36 V under 52 A surge, and exhibits 0.13 Ω dynamic resistance with only 0.1 nA reverse leakage at 15 V standoff.
For engineers reviewing the PTVS15VZ1USK datasheet, PTVS15VZ1USK pinout, PTVS15VZ1USK application, or PTVS15VZ1USK equivalent, key selection criteria include its 15 V reverse standoff voltage, ultra-low 0.29 mm profile, sub-1 Ω dynamic impedance, IEC 61000-4-2 ±30 kV ESD rating, and suitability for USB, SIM card, and battery input protection in smartphones and wearables.
Technical Context
This unidirectional TVS operates as a clamping device between anode and cathode terminals, triggering conduction when reverse voltage exceeds 16.7 V (typical breakdown). Its low dynamic resistance (0.13 Ω) ensures minimal voltage overshoot during fast transients like IEC 61000-4-5 8/20 µs surges.
The DSN1608-2 package enables direct integration into high-density PCB layouts with 0.6 mm pitch and 1.6 × 0.8 mm footprint. Its thermal design supports junction temperatures up to 150 °C, and it maintains stable clamping performance across −40 °C to +125 °C ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V reverse standoff voltage - blocks normal operating voltages up to 15 V while remaining non-conductive. |
| VBR (min) | 16.7 V breakdown voltage at 10 mA - defines earliest conduction onset during overvoltage events. |
| VCL (max) | 36 V clamping voltage at 52 A (8/20 µs) - limits maximum voltage seen by protected circuitry during worst-case surge. |
| Rdyn | 0.13 Ω dynamic resistance - determines voltage rise per ampere of surge current, critical for low overshoot. |
| IRM (typ) | 0.1 nA reverse leakage at 15 V - negligible power loss and signal interference in standby or low-power modes. |
| PPPM | 1900 W peak pulse power (8/20 µs) - quantifies single-event surge energy handling capability. |
| Cd | 340 pF diode capacitance at 1 MHz - impacts high-speed signal integrity; suitable for DC/low-frequency power rails. |
Pinout & Package
PTVS15VZ1USK uses the DSN1608-2 (SOD964) surface-mount package: 1.6 mm × 0.8 mm × 0.29 mm body, 0.6 mm terminal pitch, leadless construction with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., VBUS); conducts when transient exceeds VRWM in reverse bias. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.29 mm height - enables placement beneath connectors or in stacked PCB assemblies without mechanical interference. |
| High ESD robustness | ±30 kV contact/air discharge per IEC 61000-4-2 - eliminates need for secondary ESD stages in portable device interfaces. |
| Precision clamping | Clamps ≤36 V at 52 A (8/20 µs) - protects 15 V-rated ICs (e.g., PMICs, USB PHYs) within safe operating margins. |
| Low leakage | 0.1 nA IRM at VRWM - prevents battery drain in always-on mobile subsystems such as SIM or eMMC power rails. |
| Thermal resilience | 150 °C max junction temperature - sustains reliability in thermally dense smartphone mainboards near processors or batteries. |
Applications
| USB Power Input Protection | SIM Card Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS15VZ1US | Same electrical specs but in SOD-123FL package (1.7 × 1.25 × 0.9 mm); 3× taller and 50% larger footprint. | Less suitable for ultra-thin mobile designs; preferred where reworkability or thermal mass matters more than height. | Select when board assembly process favors larger packages or when higher thermal dissipation is prioritized over profile. |
| SMAJ15A | DO-214AC package (4.5 × 2.7 × 2.2 mm); 1500 W PPPM; 41.4 V VCL at 32.4 A; 1 µA IRM - higher leakage and clamping voltage. | Used in industrial power supplies where size is less constrained and higher clamping is acceptable. | Choose only if legacy DO-214AC footprint compatibility is required and system-level margin allows ≥41 V clamping. |
Compared with PTVS15VZ1USK, PTVS15VZ1US trades height for easier handling and solder joint inspection, while SMAJ15A sacrifices clamping precision and leakage for ruggedness in non-mobile environments - making PTVS15VZ1USK optimal for next-gen compact, battery-sensitive devices.

FAQ
Is PTVS15VZ1USK suitable for bidirectional signal line protection?
No. PTVS15VZ1USK is a unidirectional TVS diode, optimized for DC power rail protection where polarity is fixed (e.g., VBUS to GND). For bidirectional signal lines like USB D+/D− or audio paths, a bidirectional variant such as PTVS3V3Z1USK must be used to clamp both positive and negative transients.
What is the significance of the 'Z6' marking on the device top?
The 'Z6' laser marking identifies the PTVS15VZ1USK device per Nexperia's internal coding system and confirms compliance with the specified electrical parameters and DSN1608-2 package dimensions. It is not a date or lot code, and matches the ordering part number exactly per Table 4 of the datasheet.
Can PTVS15VZ1USK replace a 12 V standoff TVS in a 5 V system?
No. Its 15 V VRWM is intentionally matched to protect circuits with 15 V absolute maximum ratings. Using it in a 5 V system risks premature conduction during normal operation due to insufficient margin - a 5.0 V or 5.5 V standoff device (e.g., PTVS5V0Z1USK) would be appropriate instead.
Does the 0.13 Ω dynamic resistance apply across all current levels?
No. The 0.13 Ω value is measured under TLP conditions (100 ns square pulse, 10 A), representing small-signal dynamic impedance near conduction threshold. Under full 52 A 8/20 µs surges, effective resistance rises due to thermal effects, resulting in the measured 36 V clamping voltage (i.e., ~0.69 Ω average over the pulse).
