Product details
Overview
PTVS10VS1UTR-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 10 V reverse standoff voltage (VRWM), 17 V clamping voltage (VCL) at 23.5 A peak pulse current (IPPM), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS10VS1UTR-QX datasheet, PTVS10VS1UTR-QX pinout, PTVS10VS1UTR-QX application, or PTVS10VS1UTR-QX equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification, thermal resistance to solder point (18 K/W), and low-profile 1 mm height for space-constrained PCB layouts.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above its VRWM of 10 V, with a typical breakdown voltage (VBR) of 11.7 V at 1 mA. Its unidirectional configuration protects against positive-going surges on DC lines while blocking reverse leakage current down to 0.005 μA at VRWM.
The device sustains rated peak pulse power (PPPM) of 400 W per IEC 61643-321 (10/1000 μs waveform) up to Tj = 125 °C, derating linearly to ~220 W at 185 °C. Its cathode-anode polarity is marked by a bar on the SOD123W body, enabling unambiguous orientation during automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VCL @ IPPM | 17.0 V at 23.5 A - Clamped voltage during 10/1000 μs surge; determines protected IC's maximum stress level. |
| PPPM | 400 W - Peak surge energy handling capability per IEC 61643-321; enables robust ISO 7637-2 Pulse 1/2a/5a compliance. |
| Tj max | 185 °C - Maximum junction temperature; supports operation in engine bay or powertrain control units. |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to solder point; enables effective heat dissipation through cathode pad. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact); ±30 kV (air); 8 kV HBM - Ensures immunity to handling and system-level ESD events. |
| AEC-Q101 | Qualified - Meets automotive discrete semiconductor stress test requirements for reliability in vehicle applications. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode-bar marking, optimized for reflow and wave soldering per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); absorbs positive transients when voltage exceeds VRWM. |
| 2 (A) | Anode | Connected to ground reference; completes conduction path during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rating up to 185 °C enables use in under-hood ECUs without derating penalties. |
| Low-profile packaging | 1.0 mm height allows integration into ultra-thin modules and dense power management PCBs. |
| Automotive qualification | AEC-Q101 qualification confirms reliability for 15+ year automotive service life under thermal cycling and humidity stress. |
| Precision clamping | 17.0 V clamping at 23.5 A ensures downstream 24 V-rated components remain within safe operating area during load dump. |
| Low leakage | 0.005 μA IR at VRWM minimizes quiescent current drain in always-on battery-connected circuits. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Protection |
|---|---|
|
Use Scenario: Protects 12 V supply input of engine control units exposed to ISO 7637-2 Pulse 5a (load dump). IC Role / Device Role / Timing Role: Unidirectional TVS clamps transient spikes above 10 V to 17 V within nanoseconds.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-Q | Lower PPPM (400 W same), but higher VCL (19.5 V at 23.5 A); Rth(j-a) = 70 K/W vs. 18 K/W to solder point. | Less effective thermal coupling in high-power density layouts; requires larger copper pour for equivalent thermal performance. | Select when legacy SMA footprint compatibility is required and board space permits larger thermal relief. |
| TPSMD10A | Same VRWM (10 V), but lower PPPM (350 W); VCL = 17.5 V; not AEC-Q101 qualified; Tj max = 150 °C. | Not suitable for under-hood applications exceeding 150 °C ambient; lacks automotive qualification documentation. | Acceptable only for non-automotive industrial power supplies where temperature and qualification are not critical. |
Compared with SMAJ10A-Q and TPSMD10A, PTVS10VS1UTR-QX delivers superior thermal performance via low Rth(j-sp), guaranteed AEC-Q101 compliance, and tighter clamping-making it the preferred choice for high-reliability automotive power rail protection.

FAQ
What is the clamping voltage of PTVS10VS1UTR-QX at its rated peak pulse current?
The clamping voltage (VCL) is 17.0 V at 23.5 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 μs waveform conditions. This value ensures protected downstream components experience no more than 17 V during worst-case surge events, maintaining safe operation for 24 V-rated ICs.
Is PTVS10VS1UTR-QX suitable for under-hood automotive applications?
Yes. It is qualified to AEC-Q101 and rated for junction temperatures up to 185 °C, with thermal resistance to solder point of just 18 K/W. These characteristics enable reliable operation in engine control units, transmission control modules, and other under-hood locations where ambient temperatures exceed 125 °C.
How does the SOD123W package improve PCB layout compared to SMA or SMB packages?
The SOD123W package measures only 2.6 mm × 1.7 mm × 1.0 mm and features flat leads that reduce profile height by 40% versus standard SMA. Its low Rth(j-sp) of 18 K/W allows efficient heat transfer directly to the cathode solder pad, eliminating need for large thermal vias or copper slugs in space-constrained automotive modules.
Does PTVS10VS1UTR-QX require external biasing or control circuitry?
No. It is a passive, two-terminal device that operates automatically: below 10 V it presents <0.005 μA leakage; above breakdown (~11.7 V), it avalanches to clamp transients. No power supply, enable signal, or timing circuitry is needed-only correct anode-to-ground and cathode-to-rail placement.
