Product details
Overview
PTVS14VS1UR 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 14 V reverse standoff voltage (VRWM), 17.2 V maximum clamping voltage (VCL) at 17.2 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - enabling robust protection of 12 V automotive and industrial power supplies against IEC 61000-4-5 surges.
For engineers reviewing the PTVS14VS1UR datasheet, PTVS14VS1UR pinout, PTVS14VS1UR application, or PTVS14VS1UR equivalent, this device is selected for high-power transient suppression where low-profile mounting, precise 14 V rail alignment, and AEC-Q101 qualification (per revision history v.4) are required in space-constrained PCB layouts.
Technical Context
This unidirectional TVS operates as a clamping diode: under normal bias, it presents high impedance above VRWM = 14 V; during transients exceeding VBR ≈ 15.6–17.2 V, it avalanches to limit voltage to ≤17.2 V at IPPM = 17.2 A (10/1000 µs waveform). Its junction-to-solder-point thermal resistance is 18 K/W, supporting sustained surge handling in compact layouts.
The device uses planar silicon junction technology with cathode-anode polarity defined by a marking bar on the SOD123W body. It complies with IEC 61643-321 for surge immunity and achieves 30 kV ESD contact discharge rating per IEC 61000-4-2 - critical for unprotected input stages in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14 V - stable blocking voltage up to system nominal rail; ensures no leakage conduction during normal 12 V supply operation. |
| VBR (min/typ/max) | 15.6 / 16.4 / 17.2 V - breakdown onset range defines clamping threshold; typ. 16.4 V enables predictable surge response timing. |
| VCL @ IPPM | 17.2 V - maximum clamped voltage at 17.2 A peak pulse; limits downstream IC stress during 10/1000 µs surges. |
| PPPM | 400 W - rated peak pulse power per IEC 61643-321; supports repeated surge events without degradation. |
| IRM | 0.001 µA - ultra-low reverse leakage at VRWM; prevents parasitic loading on low-power 12 V sensor rails. |
| Rth(j-sp) | 18 K/W - thermal resistance to solder point; enables effective heat dissipation through cathode pad in FR4 PCB designs. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); protects against human-body ESD events before system-level filtering. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode marked by bar. Optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +12 V rail); avalanche conduction occurs from cathode to anode during overvoltage. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to shunt surge current away from load circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV) on 12 V lines without failure or parameter shift. |
| 1 mm profile SOD123W | Enables placement beneath connectors or near EMI filters without mechanical interference in thin-profile modules. |
| AEC-Q101 qualified | Validated for automotive power net applications per revision v.4 - includes temperature cycling, HTRB, and surge testing. |
| 0.001 µA IRM at VRWM | Eliminates measurable quiescent current draw on always-on 12 V circuits (e.g., CAN bus standby nodes). |
| 30 kV ESD contact rating | Provides first-line defense against assembly-handling ESD, reducing need for secondary board-level protection. |
Applications
| Automotive Power Rail Protection | Industrial 12 V Sensor Interface |

IC Role / Device Role / Timing Role: Low-leakage TVS on adapter input to suppress ESD and fast transients entering via patient-connected cables. Use Value: Ensures <0.001 µA leakage does not affect battery runtime while maintaining 30 kV ESD immunity for clinical handling safety. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | DO-214AC package (4.5 mm × 2.7 mm × 2.4 mm); 400 W PPPM; VCL = 23.2 V @ 17.2 A; higher VCL increases downstream stress. | Larger footprint and height limit use in ultra-thin modules; less suitable for high-density automotive ECUs. | Select when board space allows larger package and higher clamping voltage is acceptable for legacy designs. |
| 1.5SMC14A | DO-214AB package (7.1 mm × 6.2 mm × 2.6 mm); 1500 W PPPM; VCL = 23.2 V @ 64.5 A; significantly larger and higher clamping. | Designed for bulkier industrial power supplies; incompatible with SOD123W footprints and thermal constraints. | Choose only for high-energy surge zones (e.g., main AC/DC input) where SOD123W's 400 W rating is insufficient. |
Compared with SMAJ14A and 1.5SMC14A, PTVS14VS1UR delivers identical 400 W surge rating in a 60% smaller footprint and 57% lower clamping voltage (17.2 V vs. 23.2 V), making it optimal for modern 12 V systems where PCB area and voltage margin are critical.

FAQ
Is PTVS14VS1UR AEC-Q101 qualified?
Yes - per revision history v.4 (December 2025), PTVS14VS1UR is explicitly listed among the 33 types granted AEC-Q101 qualification, including stress tests for temperature cycling, high-temperature reverse bias, and surge endurance per automotive standards.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage (VCL) is 17.2 V at 17.2 A peak pulse current (IPPM), measured under the 10/1000 µs waveform per IEC 61643-321. This value is confirmed in Table 8 of the datasheet for PTVS14VS1UR.
Can PTVS14VS1UR be used in bidirectional configurations?
No - PTVS14VS1UR is strictly unidirectional, with cathode (pin 1) and anode (pin 2) terminals. Bidirectional protection requires two devices in series opposing configuration or a dedicated bidirectional TVS such as PTVS14VS1UR-S.
How does its thermal resistance compare to standard SOD-123 devices?
Its junction-to-solder-point thermal resistance (Rth(j-sp)) is 18 K/W - significantly lower than typical SOD-123 (≈40–50 K/W) due to optimized cathode tab design and CFP3 package construction, enabling better surge energy dissipation in compact layouts.
