Product details
Overview
PTVS7V5S1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection. It features 7.5 V reverse standoff voltage (VRWM), 8.77 V minimum breakdown voltage (VBR), 12.9 V clamping voltage (VCL) at 31.0 A peak pulse current (IPPM), and AEC-Q101 qualification for under-hood power rail protection.
For engineers reviewing the PTVS7V5S1UR-QX datasheet, PTVS7V5S1UR-QX pinout, PTVS7V5S1UR-QX application, or PTVS7V5S1UR-QX equivalent, this device is selected for robust ESD/ISO 7637-2 transient suppression in 12 V automotive subsystems where low-profile mounting and high surge immunity are critical.
Technical Context
This unidirectional TVS diode operates as a clamping device in series with the protected line, conducting only during positive transients relative to cathode. Its junction design enables fast response (<1 ns) to 10/1000 µs surges per IEC 61643-321, with thermal resistance to solder point (Rth(j-sp)) of 18 K/W for effective PCB heat dissipation.
Qualified to AEC-Q101, it supports operation from −55 °C to +150 °C junction temperature and withstands 30 kV contact ESD (IEC 61000-4-2) and 8 kV HBM, making it suitable for CAN/LIN bus power rails, sensor supply lines, and body control module inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.5 V - Maximum continuous reverse operating voltage before leakage exceeds 0.2 µA |
| VBR (min) | 8.33 V - Guaranteed breakdown onset at 1 mA test current, ensuring reliable turn-on margin |
| VCL @ IPPM | 12.9 V - Clamped voltage at 31.0 A peak pulse, limiting downstream IC stress during ISO 7637-2 Pulse 5a |
| PPPM | 400 W - Peak pulse power rating for 10/1000 µs waveform, defining surge energy handling |
| IRM | 0.2 µA - Reverse leakage at VRWM, minimizing quiescent power loss in always-on circuits |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to cathode solder point, enabling high-reliability PCB thermal design |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-Q | Higher VRWM (7.5 V same), but larger SMA package (4.5 mm × 2.7 mm × 2.3 mm) and lower PPPM (400 W same), VCL = 13.4 V at 29.9 A | Less suitable for ultra-low-height layouts; requires more PCB area and has higher thermal resistance | Select when legacy SMA footprint compatibility is required and height constraint is relaxed |
| TPSMD7.5 | Same SOD123W footprint, but non-automotive grade (no AEC-Q101), VRWM = 7.5 V, VCL = 12.5 V at 32.5 A, Rth(j-sp) = 22 K/W | Lacks automotive qualification and has reduced thermal performance; not approved for safety-critical modules | Select only for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with SMAJ7.5A-Q and TPSMD7.5, PTVS7V5S1UR-QX delivers identical clamping performance in a 56% lower profile package with certified automotive reliability and superior thermal coupling to PCB-critical for next-generation compact ECUs.

FAQ
What is the maximum clamping voltage of PTVS7V5S1UR-QX under standard test conditions?
The clamping voltage (VCL) is 12.9 V measured at 31.0 A peak pulse current (IPPM) using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the maximum voltage seen by downstream circuitry during surge events.
Does PTVS7V5S1UR-QX support bidirectional transient suppression?
No, PTVS7V5S1UR-QX is a unidirectional TVS diode. It conducts only when the cathode is at a higher potential than the anode, making it suitable for DC power line protection. For AC or data-line applications requiring symmetrical clamping, a bidirectional variant such as PTVS7V5S1UR-Q (dual-diode configuration) must be used instead.
How does the SOD123W package affect thermal performance in high-power automotive designs?
The SOD123W package achieves a junction-to-solder-point thermal resistance (Rth(j-sp)) of 18 K/W when mounted per recommended footprint, enabling efficient heat transfer to the PCB copper pour. This allows sustained 400 W surge handling without exceeding 150 °C junction temperature-even in enclosed under-hood environments with limited airflow.
Is PTVS7V5S1UR-QX compatible with lead-free reflow soldering processes?
Yes, PTVS7V5S1UR-QX is fully compatible with standard lead-free reflow profiles (JEDEC J-STD-020). The CFP3 package supports peak temperatures up to 260 °C for 30 seconds, and Nexperia provides validated reflow footprints for both single- and double-sided PCB assembly in its official application note AN10774.
