Product details
Overview
PTVS15VS1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. Confirmed parameters: VRWM = 15 V, VBR(min) = 16.7 V, VCL = 24.4 V at IPPM = 16.4 A, Tj ≤ 185 °C, and IRM ≤ 0.001 µA at VRWM. Used in industrial power management systems exposed to IEC 61000-4-5 surges.
For engineers reviewing the PTVS15VS1UTR,115 datasheet, PTVS15VS1UTR,115 pinout, PTVS15VS1UTR,115 application, or PTVS15VS1UTR,115 equivalent, key selection criteria include clamping voltage under 10/1000 µs surge, junction temperature derating above 25 °C, standoff voltage margin relative to DC rail, and SOD123W thermal resistance to PCB solder point (Rth(j-sp) = 18 K/W).
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM (15 V), breaks down sharply at VBR ≥ 16.7 V, and clamps transients to ≤24.4 V at 16.4 A peak pulse current (10/1000 µs waveform per IEC 61643-321). Its silicon avalanche structure enables stable breakdown with SZ = 0.5 mV/K temperature coefficient.
Thermal design relies on low-profile SOD123W package (1 mm height) and direct cathode-to-PCB thermal path: Rth(j-sp) = 18 K/W ensures effective heat transfer during repetitive surge events, while Tj max = 185 °C supports operation in engine control units and industrial motor drives where ambient exceeds 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse working voltage before leakage rises; sets minimum DC rail margin for reliable blocking. |
| VBR (min) | 16.7 V - Minimum breakdown voltage at 1 mA; guarantees activation before downstream IC damage thresholds. |
| VCL @ IPPM | 24.4 V - Clamping voltage at 16.4 A peak pulse; defines maximum transient voltage seen by protected circuitry. |
| PPPM | 400 W - Peak pulse power rating (10/1000 µs); determines energy absorption capability without failure. |
| IRM | ≤0.001 µA - Reverse leakage at VRWM; ensures negligible standby current in battery-powered systems. |
| Tj max | 185 °C - Maximum junction temperature; enables use in under-hood automotive or high-temp industrial environments. |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to cathode solder point; critical for sustained surge handling on standard FR4 PCBs. |
Pinout & Package
PTVS15VS1UTR,115 uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by bar. Thermal performance optimized via cathode tab soldering to PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 15 V rail); marking bar identifies this terminal; primary thermal path to PCB. |
| 2 (A) | Anode | Connected to ground reference; completes shunt path during overvoltage events; low-inductance layout required. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - Enables placement near heat sources (e.g., power MOSFETs, inductors) without derating. |
| Low-profile SMD package | SOD123W (1 mm height) - Reduces board space and improves airflow in dense power modules. |
| Precision clamping | VCL = 24.4 V at 16.4 A - Tight voltage limit protects 24 V logic interfaces and microcontrollers with 28 V absolute max ratings. |
| Ultra-low leakage | IRM ≤ 0.001 µA - Eliminates measurable current drain in always-on 15 V sensor supply rails. |
| IEC 61000-4-2 ESD robustness | 30 kV contact discharge - Survives repeated electrostatic events without parameter shift or degradation. |

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 | Lower PPPM (400 W same), but higher VCL = 24.4 V (same), VRWM = 15 V (same); Rth(j-a) = 70 K/W vs. 18 K/W to solder point. | Less effective thermal dissipation in high-power density layouts; requires larger copper pour for equivalent surge endurance. | Select when legacy SMA footprint is mandatory and thermal budget permits higher junction rise. |
| 1.5SMC15A | Higher PPPM (1500 W), but larger DO-214AB package (4.5 mm height); VRWM = 15 V, VCL = 24.4 V; Tj max = 175 °C. | Not suitable for ultra-low-profile designs; better for infrequent high-energy surges rather than repetitive industrial transients. | Choose only if surge energy exceeds 400 W and board height >4 mm is available. |
Compared with SMAJ15A and 1.5SMC15A, PTVS15VS1UTR,115 delivers superior thermal coupling (Rth(j-sp) = 18 K/W) and high-temperature reliability (Tj ≤ 185 °C), making it optimal for compact, thermally constrained industrial and automotive power nodes where consistent clamping performance across temperature is critical.

FAQ
What is the maximum clamping voltage of PTVS15VS1UTR,115 under a 10/1000 µs surge?
The clamping voltage VCL is 24.4 V at IPPM = 16.4 A, measured per IEC 61643-321 using the standard 10/1000 µs current waveform. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C junction), with no derating required up to Tj = 150 °C.
Can PTVS15VS1UTR,115 be used in automotive applications?
Yes - PTVS15VS1UTR,115 is qualified for high-temperature operation up to 185 °C junction temperature and meets IEC 61000-4-2 (30 kV contact discharge) and IEC 61643-321 surge standards. It is deployed in non-safety-critical automotive subsystems such as engine control unit (ECU) sensor supplies and body electronics, though not AEC-Q200 qualified.
How does the SOD123W package improve thermal performance versus standard SOD-123?
The SOD123W (CFP3) package features an extended cathode tab that increases solder joint area and reduces thermal resistance to the PCB. Its Rth(j-sp) = 18 K/W is 3.9× lower than standard SOD-123 (≈70 K/W), enabling faster heat extraction during repetitive surges and sustaining higher average power dissipation in compact layouts.
What is the reverse leakage current specification at 15 V and 125 °C?
At VRWM = 15 V and Tj = 125 °C, the reverse leakage current IRM is ≤0.1 µA - confirmed in Table 8 of the datasheet. This remains well within the 0.001 µA limit specified at 25 °C, ensuring minimal impact on 15 V rail stability even in high-ambient-temperature environments.
