Product details
Overview
PTVS7V0S1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features a 7.0 V reverse standoff voltage (VRWM), 8.60 V maximum clamping voltage (VCL) at 33.3 A peak pulse current (IPPM), and <3 µA reverse leakage at VRWM - used in industrial power supply input protection against IEC 61000-4-5 surges.
For engineers reviewing the PTVS7V0S1UR,115 datasheet, PTVS7V0S1UR,115 pinout, PTVS7V0S1UR,115 application, or PTVS7V0S1UR,115 equivalent, key selection criteria include clamping performance at 33.3 A, thermal resistance to solder point (18 K/W), AEC-Q101 qualification status per revision history, and compatibility with standard SOD123W reflow footprints.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggered when reverse voltage exceeds its 7.0 V VRWM threshold, entering low-impedance conduction to clamp transients up to 12.0 V (VCL max) during 10/1000 µs pulses. Its junction-to-solder-point thermal resistance of 18 K/W enables effective heat dissipation in compact PCB layouts.
The device complies with IEC 61643-321 for surge immunity and supports ESD robustness per IEC 61000-4-2 (30 kV contact discharge). Its 1 mm profile and 2.6 mm × 1.7 mm footprint suit space-constrained industrial and embedded power rail designs requiring fast response (<1 ns) and low capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min) | 7.78 V - Minimum breakdown voltage at 10 mA; ensures reliable turn-on above VRWM with margin. |
| VCL (max) | 12.0 V - Maximum clamped voltage at IPPM = 33.3 A; determines protected circuit's peak stress level. |
| IPPM | 33.3 A - Peak pulse current under 10/1000 µs waveform; quantifies surge energy handling capability. |
| IRM | 3 µA - Reverse leakage at VRWM; ensures minimal standby power loss in always-on systems. |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to cathode solder point; enables stable operation at 150 °C Tj. |
| ESD (HBM) | >4 kV - Human Body Model rating; supports robust handling in manual assembly environments. |
Pinout & Package
PTVS7V0S1UR,115 uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +VDC rail); carries surge current into ground path during clamping. |
| 2 (A) | Anode | Connected to system ground; completes low-impedance path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Rated per IEC 61643-321 (10/1000 µs), enabling protection against high-energy surges without derating at 25 °C. |
| AEC-Q101 qualified | Qualified per revision v.4 (2025), confirming reliability for automotive-grade environments despite non-automotive marking. |
| 1 mm package height | Enables ultra-low-profile placement in stacked or shielded PCB assemblies where Z-axis clearance is constrained. |
| SOD123W footprint | Standardized land pattern (2.1 mm × 1.4 mm pads, 0.1 mm stencil) ensures drop-in compatibility with existing reflow processes. |
| 30 kV ESD contact rating | Exceeds IEC 61000-4-2 Level 4, reducing need for secondary ESD protection in front-end interfaces. |
Applications
| Industrial Power Supply Input Protection | Programmable Logic Controller (PLC) I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Lower PPPM (400 W same), but higher VCL (12.4 V max at 32.3 A) and larger SMA package (4.5 mm × 2.7 mm). | Less suitable for ultra-thin designs; requires larger PCB area and higher thermal mass for equivalent power dissipation. | Select when legacy SMA footprint compatibility is required and 0.4 V higher clamping is acceptable. |
| 1.5SMC7.0A | Same VRWM/VCL specs but 1500 W PPPM rating and DO-214AB package (7.1 mm × 6.2 mm); 10× larger footprint. | Over-specified for board space-constrained applications; introduces unnecessary parasitic inductance in high-frequency surge paths. | Choose only for legacy designs needing backward compatibility with 1.5 kW surge standards and no size constraints. |
Compared with SMAJ7.0A and 1.5SMC7.0A, PTVS7V0S1UR,115 delivers identical 7.0 V standoff and 400 W surge rating in a 65% smaller footprint than SMA and 92% smaller than DO-214AB - optimizing PCB real estate and thermal response in modern industrial modules.

FAQ
What is the maximum clamping voltage of PTVS7V0S1UR,115 at its rated peak pulse current?
The maximum clamping voltage (VCL) is 12.0 V at IPPM = 33.3 A under 10/1000 µs waveform conditions, measured per IEC 61643-321. This value ensures protected circuits experience no more than 12.0 V during worst-case surge events, preserving downstream IC integrity.
Is PTVS7V0S1UR,115 qualified for automotive use?
Yes - per revision v.4 (December 2025) of the official Nexperia datasheet, PTVS7V0S1UR,115 is explicitly listed among the 33 types granted AEC-Q101 qualification. This confirms its suitability for automotive environments including engine control units and body electronics.
How does the SOD123W package affect thermal performance compared to SMA?
The SOD123W package achieves Rth(j-sp) = 18 K/W - significantly lower than typical SMA packages (~50–60 K/W) - due to its direct cathode tab solder connection and optimized copper pad layout. This allows sustained 400 W pulse handling with less board-level thermal spreading.
Can PTVS7V0S1UR,115 replace older PTVS7V0S1U parts?
Yes - PTVS7V0S1UR,115 is the updated tape-and-reel variant (115 suffix) of the base PTVS7V0S1U, sharing identical electrical specs, SOD123W package, and AEC-Q101 qualification. The "R" denotes RoHS-compliant finish; "115" indicates 3,000-piece reel packaging.
