Product details
Overview
PTVS14VS1UTR,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. It features 14 V reverse standoff voltage (VRWM), 23.2 V clamping voltage (VCL) at 5 mA, 17.2 A peak pulse current (IPPM), and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS14VS1UTR,115 datasheet, PTVS14VS1UTR,115 pinout, PTVS14VS1UTR,115 application, or PTVS14VS1UTR,115 equivalent, this device serves as a compact, high-reliability TVS for industrial power supply surge suppression, automotive body electronics, and high-ambient-temperature DC/DC converter input protection where low-profile mounting and thermal stability are critical.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transients above its VRWM of 14 V. Its VBR (breakdown voltage) is specified at 15.6–17.2 V (min–max) with 5 mA test current, ensuring predictable turn-on behavior under ESD or lightning-induced surges per IEC 61643-321 (10/1000 μs waveform).
Thermal design is enabled by Rth(j-sp) = 18 K/W (junction-to-solder-point), supporting reliable operation at Tj ≤ 185 °C. The cathode-anode polarity is marked by a bar on the SOD123W body, and its low 1 mm profile allows placement near sensitive IC inputs without height interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14 V - maximum continuous reverse operating voltage before clamping begins |
| VCL @ IPPM | 23.2 V - clamping voltage at 17.2 A peak pulse current, limiting downstream voltage stress |
| PPPM | 400 W - rated peak pulse power handling capability per IEC 61643-321 10/1000 μs waveform |
| IRM | 0.001 μA - ultra-low reverse leakage at VRWM, minimizing standby power loss |
| Tj max | 185 °C - extended junction temperature rating enabling use in engine bay or industrial enclosures |
| Rth(j-sp) | 18 K/W - low thermal resistance to solder point, supporting efficient PCB heat dissipation |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - robust electrostatic immunity for handling and assembly |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead, low-profile design optimized for automated reflow assembly and space-constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +12 V rail); marking bar identifies this terminal |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation up to 185 °C junction temperature, suitable for under-hood or industrial control environments |
| Low-profile SMD package | 1.0 mm max height enables routing beneath connectors or stacked components without mechanical interference |
| Precision clamping performance | VBR tolerance ±6.4 % (15.6–17.2 V) ensures consistent surge response across production lots |
| Ultra-low leakage | IRM ≤ 0.001 μA at VRWM minimizes quiescent current draw in battery-powered systems |
| Robust ESD immunity | 30 kV contact discharge rating reduces risk of field failure due to handling or system-level ESD events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | Lower PPPM (400 W same), but VRWM = 14 V, VCL = 23.2 V; SMA package (2.5 mm height vs. 1.0 mm) | Less suitable for ultra-low-profile layouts; higher Rth(j-a) limits high-temp derating | Select when board height >1.0 mm is acceptable and legacy SMA footprint reuse is prioritized |
| 1.5SMC14A | Same VRWM/VCL, but larger SMC package (7.1 mm × 6.2 mm × 2.6 mm); PPPM = 1500 W | Better energy handling for rare high-energy events, but incompatible with dense SMT layouts | Choose only if surge energy exceeds 400 W and PCB real estate permits large footprint |
Compared with SMAJ14A and 1.5SMC14A, PTVS14VS1UTR,115 delivers identical electrical protection in a 60 % lower profile package with superior thermal coupling to PCB-enabling reliable operation in thermally constrained, high-density industrial and automotive modules where height and junction temperature are critical.

FAQ
What is the maximum clamping voltage of PTVS14VS1UTR,115 under full-rated surge current?
The clamping voltage (VCL) is 23.2 V at 17.2 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 μs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C) and defines the maximum voltage seen by downstream circuitry during a worst-case transient event.
How does the SOD123W package improve thermal performance compared to standard SMA packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W-nearly half the typical junction-to-solder-point resistance of SMA packages-due to its optimized copper tab geometry and direct thermal path to the PCB cathode pad. This enables sustained operation at 185 °C junction temperature without derating in compact, high-power-density layouts.
Can PTVS14VS1UTR,115 be used in bidirectional protection configurations?
No. PTVS14VS1UTR,115 is a unidirectional TVS diode with cathode-anode polarity. Bidirectional protection requires either two devices in series opposition or a dedicated bidirectional part (e.g., PTVS14VS1UTR,115's counterpart PTVS14VS1UTR,115 is not bidirectional; no such variant exists in this series). Its schematic symbol and pinning confirm single-polarity operation.
What is the significance of the "CF" marking code on the device body?
The marking code "CF" corresponds exclusively to PTVS14VS1UTR per Nexperia's official marking table. It is laser-etched on the cathode side of the SOD123W package and serves as the visual identifier for traceability and counterfeit prevention-no functional or parametric difference exists between marked and unmarked units beyond this identification role.
