Product details
Overview
PTVS15VS1UR,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 15 V reverse standoff voltage (VRWM), 18.5 V maximum clamping voltage (VCL) at 24.4 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - enabling robust protection of 12–15 V automotive and industrial power inputs.
For engineers reviewing the PTVS15VS1UR,115 datasheet, PTVS15VS1UR,115 pinout, PTVS15VS1UR,115 application, or PTVS15VS1UR,115 equivalent, this device serves as a compact, AEC-Q101-qualified surge protector for 12 V battery-supplied systems where low-profile mounting, fast response (<1 ns), and high-energy handling (IEC 61643-321 10/1000 µs) are critical.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggering when reverse voltage exceeds VRWM = 15 V and clamping to ≤18.5 V at IPPM = 24.4 A under standardized 10/1000 µs waveform stress. Its junction-to-solder-point thermal resistance is 18 K/W, supporting reliable operation up to Tj = 150 °C in constrained PCB layouts.
The device uses cathode-anode polarity (marked with bar on cathode), requires no biasing, and delivers ESD immunity >4 kV HBM and 30 kV IEC 61000-4-2 contact discharge - making it suitable for unprotected input nodes exposed to load dump, ISO 7637-2 pulses, and electrostatic events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (IEC 61643-321 10/1000 µs); sustains single high-energy transients without failure |
| Reverse Standoff Voltage | VRWM = 15 V; blocks normal 12 V system operation while remaining fully off |
| Clamping Voltage | VCL ≤ 18.5 V at IPPM = 24.4 A; limits downstream IC voltage stress during surge |
| Reverse Leakage | IRM = 0.001 µA at VRWM; negligible standby current draw in always-on circuits |
| Package | SOD123W (CFP3); 2.6 × 1.7 × 1.0 mm footprint with 1 mm height - fits ultra-thin PCB assemblies |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council standard; validated for automotive power rail use |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2-terminal, flat-lead, cathode-bar marked configuration; body dimensions 2.6 mm × 1.7 mm × 1.0 mm; optimized for reflow soldering with recommended stencil thickness 0.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side (bar); connects to protected line (e.g., +12 V rail); carries surge current into ground path |
| 2 (A) | Anode | Connects to circuit ground; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile packaging | 1.0 mm max height enables use in space-constrained automotive ECUs and portable industrial controllers |
| High surge current capability | IPPM = 24.4 A supports ISO 7637-2 Pulse 5a (load dump) suppression without derating |
| Ultra-low leakage | 0.001 µA at 15 V minimizes quiescent power loss in battery-backed systems |
| Automotive-grade reliability | AEC-Q101 qualification confirmed in revision v.4 (Dec 2025); valid for automotive power supply protection |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC package (4.5 mm × 2.7 mm × 2.3 mm); 400 W rating; VRWM = 15 V; VCL = 24.4 V at 16.3 A | Larger footprint and higher clamping voltage reduce effectiveness in tight 12 V rail designs | Choose SMAJ15A only if board layout allows larger package and higher clamping is acceptable |
| SMCJ15A | DO-214AB package (7.1 mm × 6.2 mm × 2.6 mm); 1500 W rating; VRWM = 15 V; VCL = 24.4 V at 61.5 A | Over-specified power rating and 7× larger area make it unsuitable for space-limited automotive modules | Select SMCJ15A only for high-energy industrial mains-connected equipment requiring >1 kW surge handling |
Compared with SMAJ15A and SMCJ15A, PTVS15VS1UR,115 delivers identical VRWM but achieves lower VCL (18.5 V vs. 24.4 V) and occupies 85 % less PCB area than SMAJ15A - making it optimal for modern automotive and compact industrial electronics where voltage margin and board space are critical.

FAQ
Is PTVS15VS1UR,115 qualified for automotive use?
Yes. Per revision v.4 of the December 2025 datasheet, PTVS15VS1UR,115 is explicitly listed among the 33 types granted AEC-Q101 qualification. It has passed stress tests including high-temperature operating life, temperature cycling, and ESD per MIL-STD-883 and IEC 61000-4-2, confirming suitability for automotive power rail protection.
What is the maximum clamping voltage at rated surge current?
At its rated peak pulse current of 24.4 A (IPPM), PTVS15VS1UR,115 clamps to a maximum of 18.5 V, measured under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across the full operating junction temperature range (−55 °C to 150 °C) and ensures safe voltage limiting for 12 V system components.
How does the SOD123W package affect thermal performance?
The SOD123W package provides a junction-to-solder-point thermal resistance (Rth(j-sp)) of 18 K/W, significantly lower than standard SOD-123 (≈35 K/W). This enables efficient heat transfer to the PCB copper pour, allowing sustained operation at 150 °C junction temperature even under repeated 400 W pulses when mounted per Nexperia's recommended footprint.
Can PTVS15VS1UR,115 replace PTVS15VS1U,115?
No. PTVS15VS1U,115 uses the older SOD-123 package (3.7 mm × 1.6 mm × 1.6 mm) with higher Rth(j-a) and no AEC-Q101 qualification in current revisions. PTVS15VS1UR,115 is not a drop-in replacement due to different land pattern, lower profile (1.0 mm vs. 1.6 mm), and updated automotive qualification status - redesign of solder pads and validation per AEC-Q101 is required.
