Product details
Overview
PTVS14VS1UTR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 14 V, VBR(min) = 15.6 V, VCL = 23.2 V at IPPM = 17.2 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS14VS1UTR-QX datasheet, PTVS14VS1UTR-QX pinout, PTVS14VS1UTR-QX application, or PTVS14VS1UTR-QX equivalent, this device supports AEC-Q101-compliant automotive ECU power supply clamping, high-temp industrial sensor interface protection, and robust 14 V rail surge suppression with low-profile surface-mount integration.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above its reverse standoff voltage. Its unidirectional configuration allows forward conduction only during negative surges relative to cathode, making it suitable for DC-biased lines where polarity is fixed.
It delivers 400 W peak pulse power per IEC 61643-321 (10/1000 µs waveform) at 25 °C, with derating to ~220 W at 150 °C junction temperature. Thermal resistance Rth(j-sp) = 18 K/W enables effective heat transfer via cathode solder point under sustained stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC bias margin for 14 V systems. |
| VBR (min) | 15.6 V - Minimum breakdown voltage at IR = 1 mA; ensures reliable triggering above normal operating voltage. |
| VCL @ IPPM | 23.2 V - Clamping voltage at 17.2 A peak pulse current; limits downstream IC voltage stress during surge events. |
| PPPM | 400 W - Peak pulse power handling (10/1000 µs); sustains 17.2 A surge without failure at 25 °C ambient. |
| IRM | 0.001 µA - Reverse leakage at VRWM; negligible current draw in standby, critical for low-power battery systems. |
| Tj max | 185 °C - Maximum junction temperature; supports operation in engine bay or under-hood automotive environments. |
| ESD rating | ±30 kV (IEC 61000-4-2 contact/air); provides system-level ESD immunity without external staging. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body height; flat lead profile optimized for automated placement and thermal relief on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side with bar; connects to protected line (e.g., 14 V rail); carries clamped surge current to ground path. |
| 2 (A) | Anode | Connects to system ground; completes avalanche conduction path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard; eliminates qualification burden for Tier 1 suppliers. |
| 185 °C junction rating | Enables direct placement near heat sources (e.g., power converters, motor drivers) without derating penalties. |
| 1 mm profile | Reduces board space and improves airflow clearance in dense automotive modules and industrial controllers. |
| Low IRM (0.001 µA) | Minimizes quiescent power loss in always-on 14 V circuits such as CAN transceivers or microcontroller power domains. |
| IEC 61643-321 compliant | Guarantees standardized 10/1000 µs surge response; simplifies compliance testing for ISO 7637-2 and similar standards. |

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 vs. 400 W), but VRWM = 14 V, VCL = 23.2 V, same SOD-123 package; not AEC-Q101 qualified. | Limited to non-automotive industrial use due to lack of automotive qualification and higher IRM (1 µA). | Select when AEC-Q101 is not required and cost sensitivity outweighs long-term reliability validation. |
| SMCJ14A-Q | Higher PPPM (1500 W), DO-214AB package (7.11 mm × 6.22 mm); VRWM = 14 V, VCL = 23.2 V; AEC-Q101 qualified. | Requires significantly more PCB area; better for high-energy surges but over-specified for typical 14 V automotive clamping. | Choose only if system-level surge tests exceed IEC 61643-321 10/1000 µs or require >400 W margin. |
Compared with SMAJ14A and SMCJ14A-Q, PTVS14VS1UTR-QX uniquely balances AEC-Q101 compliance, 1 mm low-profile packaging, and precise 14 V clamping in a cost-effective SOD123W footprint-making it optimal for space-constrained, high-temp automotive modules where qualification and size are decisive.

FAQ
What is the maximum clamping voltage of PTVS14VS1UTR-QX at rated peak pulse current?
The clamping voltage VCL is 23.2 V at IPPM = 17.2 A under 10/1000 µs waveform conditions per IEC 61643-321. This value is measured at Tj = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS14VS1UTR-QX suitable for bidirectional transient protection?
No - PTVS14VS1UTR-QX is unidirectional. It conducts only when the cathode is positive relative to the anode, making it appropriate for DC-biased lines like 14 V automotive rails. For AC or bipolar signal lines, a bidirectional variant (e.g., PTVS14VS1UTR-Q) must be selected.
How does thermal performance change at elevated ambient temperatures?
Rated peak pulse power decreases with rising junction temperature: at Tj = 150 °C, PPPM drops to approximately 220 W. Derating curves in Figure 2 of the datasheet show linear reduction from 400 W at 25 °C to zero at 185 °C, requiring layout attention to Rth(j-sp) = 18 K/W.
Can PTVS14VS1UTR-QX replace older P6SMB14A in existing designs?
Yes, with caveats: both share VRWM = 14 V and similar VCL, but PTVS14VS1UTR-QX offers AEC-Q101 qualification, 185 °C rating, and SOD123W's 1 mm height versus P6SMB14A's DO-214AA (2.5 mm height). Layout redesign is needed for footprint and thermal pad optimization.
