Product details
Overview
PTVS12VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) surface-mount package, designed for clamping transient overvoltages on DC power rails. It features 12 V reverse standoff voltage (VRWM), 14.7 V maximum clamping voltage (VCL) at 19.9 A peak pulse current (IPPM), and 0.005 µA reverse leakage at VRWM - optimized for protection of 12 V automotive and industrial power supply inputs.
For engineers reviewing the PTVS12VS1UR,115 datasheet, PTVS12VS1UR,115 pinout, PTVS12VS1UR,115 application, or PTVS12VS1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (18 K/W), AEC-Q101 qualification status, and compatibility with high-density PCB layouts requiring ≤1 mm profile height.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche breakdown when transient voltage exceeds its 13.3–14.7 V breakdown range (VBR). Its response time is sub-nanosecond, enabling suppression of fast transients such as ISO 7637-2 load dump spikes or ESD events per IEC 61000-4-2 (30 kV contact discharge).
The device sustains 400 W peak pulse power (PPPM) under standardized 10/1000 µs waveform at Tj = 25 °C, with derating to ~220 W at 125 °C junction temperature. Thermal resistance from junction to solder point is 18 K/W, enabling effective heat transfer to PCB copper when mounted per recommended footprint (FR4, cathode pad ≥1 cm²).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail voltage margin. |
| VBR (min/typ/max) | 13.3 / 14.0 / 14.7 V - breakdown voltage range at 1 mA test current; ensures reliable turn-on above nominal rail. |
| VCL @ IPPM | 19.9 V - clamping voltage at 19.9 A peak pulse current; limits downstream voltage stress during surge. |
| PPPM | 400 W - rated peak pulse power per IEC 61643-321 (10/1000 µs); determines energy-handling capability. |
| IRM | 0.005 µA - reverse leakage current at VRWM; minimizes standby power loss in battery-critical systems. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point; enables efficient PCB heat sinking with standard layout. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides robust system-level ESD immunity without external shielding. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); carries surge current into ground path during clamping. |
| 2 | Anode (A) | Connected to system ground; completes low-impedance path for transient current during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors; supports deployment in automotive power modules. |
| 1 mm max height | Enables use in ultra-thin electronics (e.g., ADAS ECUs, infotainment head units) where Z-axis space is constrained. |
| Low IRM (0.005 µA) | Reduces quiescent current draw in always-on 12 V circuits (e.g., CAN bus nodes, telematics), extending battery life. |
| 400 W PPPM rating | Handles high-energy transients like ISO 7637-2 Pulse 5a (load dump) without degradation when properly heatsinked. |
| SOD123W footprint | Standardized 2.6 mm × 1.7 mm land pattern compatible with automated reflow assembly and IPC-7351B design rules. |
Applications
| Automotive Power Input Protection | Industrial 12 V DC Power Rail |
|---|---|
Use Scenario: Protecting engine control unit (ECU) 12 V input against load dump transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional voltage clamp placed between battery feed and LDO/regulator input. Use Value: Limits transient voltage to ≤19.9 V, preventing damage to downstream 24 V-tolerant regulators and MCU power domains. |
Use Scenario: Safeguarding programmable logic controller (PLC) 12 V auxiliary supply from switching noise and inductive kickback. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing microsecond-scale surges on DIN-rail-mounted power distribution boards. Use Value: Maintains <0.005 µA leakage to avoid false tripping of undervoltage lockout (UVLO) circuits during normal operation. |
| Telematics Module Surge Protection | Smart Sensor Node Power Interface |
Use Scenario: Shielding LTE/GNSS module power input from hot-swap transients and ESD events in vehicle-mounted trackers. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of DC-DC converter and PMIC. Use Value: 30 kV ESD rating and 1 ns response ensure immunity to connector mating/unmating discharges without signal interruption. |
Use Scenario: Securing battery-powered IoT sensor node input against electrostatic discharge during field installation or maintenance. IC Role / Device Role / Timing Role: Low-leakage TVS integrated directly at JST-XH connector entry point on compact PCB. Use Value: 1 mm profile allows placement adjacent to connectors in space-constrained enclosures (<15 mm height). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | DO-214AC package (4.5 mm × 2.7 mm × 2.2 mm); 400 W PPPM; 13.3 V VRWM; 19.9 V VCL @ 21.6 A. | Larger footprint and 2.2 mm height limit use in ultra-thin designs; higher Rth(j-a) reduces thermal margin in dense layouts. | Select when legacy DO-214AC footprint is fixed and board space is not constrained. |
| SMCJ12A | DO-214AB package (7.1 mm × 6.2 mm × 2.6 mm); 1500 W PPPM; 12 V VRWM; 19.9 V VCL @ 75.8 A. | Three-times higher surge capacity but incompatible with SOD123W land pattern; requires redesign of PCB layout and stencil. | Choose only when system-level testing confirms need for >400 W energy handling and board area permits larger package. |

FAQ
Is PTVS12VS1UR,115 qualified for automotive applications?
Yes - PTVS12VS1UR,115 is AEC-Q101 qualified per Nexperia's revision history v.4 (December 2025), confirming compliance with stress test requirements for discrete semiconductors in automotive environments. This qualification applies specifically to this part number, as confirmed in the official datasheet revision notice listing PTVS12VS1UR among the 33 products retained under standard qualification.
What is the maximum clamping voltage under full-rated surge current?
At its rated peak pulse current of 19.9 A (IPPM), PTVS12VS1UR,115 clamps to a maximum of 19.9 V per Table 8 of the datasheet. This value is measured under IEC 61643-321 10/1000 µs waveform conditions at Tj = 25 °C and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
How does thermal resistance affect PCB layout decisions?
With Rth(j-sp) = 18 K/W, optimal thermal performance requires direct copper connection from the cathode pad to a ≥1 cm² thermal pad on inner or outer PCB layers. The datasheet specifies that this value assumes soldering to a defined cathode tab area - reducing pad size or omitting thermal vias increases junction temperature and degrades PPPM derating, especially in enclosed enclosures.
Can PTVS12VS1UR,115 replace PTVS12VS1UR without changes?
Yes - PTVS12VS1UR,115 and PTVS12VS1UR share identical electrical specifications, SOD123W package dimensions, and marking (AC), differing only in tape-and-reel packaging configuration (115 = 3000 pcs/reel, standard variant). No schematic, layout, or firmware changes are required for drop-in replacement in existing designs.
