Product details
Overview
PTVS9V0S1UTR,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 9.0 V reverse standoff voltage (VRWM), 10.0–11.1 V breakdown voltage (VBR), 15.4 V clamping voltage (VCL) at 26.0 A peak pulse current, and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS9V0S1UTR,115 datasheet, PTVS9V0S1UTR,115 pinout, PTVS9V0S1UTR,115 application, or PTVS9V0S1UTR,115 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance to solder point (18 K/W), low leakage (≤5 µA at VRWM), and compatibility with high-reliability industrial power management layouts.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transient voltages above its specified VRWM. Its V-I characteristic exhibits sharp knee behavior with low dynamic impedance, enabling fast response (<1 ns) to ESD and lightning-induced surges per IEC 61643-321 (10/1000 µs waveform).
Thermal design is critical: Rth(j-sp) = 18 K/W allows effective heat transfer from junction to cathode solder point, supporting sustained operation at Tamb = 185 °C when mounted on ceramic PCB or optimized FR4 layout. Temperature coefficient of breakdown voltage is +7.1 mV/K, ensuring predictable VBR drift across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 9.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min/typ/max) | 10.0 / 10.55 / 11.10 V at 5 mA - Ensures reliable turn-on within 1.1 V tolerance band for consistent surge suppression. |
| VCL @ IPPM | 15.4 V at 26.0 A - Limits downstream IC voltage stress during 400 W transient events; enables robust 24 V system protection. |
| IRM | ≤5 µA at VRWM - Minimizes standby power loss and avoids false triggering in low-current sensing circuits. |
| Tj max | 185 °C - Supports operation in engine control units, industrial motor drives, and enclosed power supplies without derating. |
| Rth(j-sp) | 18 K/W - Enables direct thermal coupling to PCB copper pour via cathode tab, critical for pulsed power dissipation. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height; marking bar denotes cathode; optimized for reflow and wave soldering per Nexperia footprint guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 24 V rail); carries full surge current during clamping; primary thermal path to PCB. |
| 2 (A) | Anode | Connected to ground reference; completes conduction path during transient; requires low-inductance grounding for optimal clamping speed. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Junction rated to 185 °C with no derating-enables use in under-hood automotive modules and industrial inverters. |
| Low-profile SMD package | 1.0 mm max height-reduces board clearance issues in stacked or space-constrained power supply designs. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2)-eliminates need for secondary ESD protection in front-end interfaces. |
| Precision clamping window | VBR tolerance ±5.5% and VCL/VBR ratio ≤1.54-ensures tight voltage margin between protection threshold and IC absolute maximum ratings. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | DO-214AC package; 1.9 mm height; 350 W PPPM; VCL = 14.4 V @ 27.8 A | Higher profile limits use in ultra-thin modules; lower peak power reduces margin for repetitive surges. | Preferred where legacy DO-214AC footprint exists and thermal constraints are less severe. |
| SMCJ9.0A | DO-214AB package; 2.6 mm height; 1500 W PPPM; VCL = 14.4 V @ 104 A | Larger size and higher clamping current suit heavy-duty industrial equipment but increase parasitic inductance. | Chosen when surge energy exceeds 400 W and board space permits larger SMD footprint. |
Compared with SMAJ9.0A and SMCJ9.0A, PTVS9V0S1UTR,115 delivers superior thermal performance in minimal volume, making it optimal for compact, high-temperature embedded systems where 400 W surge handling and 1 mm profile are jointly required.

FAQ
What is the maximum clamping voltage of PTVS9V0S1UTR,115 under standard test conditions?
The clamping voltage (VCL) is 15.4 V at 26.0 A peak pulse current (IPPM), measured using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Does PTVS9V0S1UTR,115 meet automotive qualification standards?
No-PTVS9V0S1UTR,115 is not AEC-Q200 qualified. While it operates up to 185 °C junction temperature and withstands 30 kV ESD, Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical automotive applications unless separately validated by the customer.
How does the SOD123W package improve thermal performance compared to standard SOD-123?
The SOD123W (CFP3) variant features an enlarged cathode pad and optimized internal leadframe geometry, reducing Rth(j-sp) to 18 K/W-nearly 4× better than standard SOD-123. This enables efficient heat transfer directly from junction to solder point, critical for sustaining 400 W pulse power in confined layouts.
Can PTVS9V0S1UTR,115 be used in bidirectional configurations?
No-it is strictly unidirectional. The device conducts only when cathode voltage exceeds anode by ≥VBR; reverse polarity operation will not provide protection. For bidirectional surge suppression, two PTVS9V0S1UTR,115 devices must be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., PTVS9V0S1UTR-B) should be selected.
