Product details
Overview
PTVS11VS1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection at 11 V reverse standoff voltage. It delivers 22.0 A peak pulse current (IPPM), clamps transients to ≤18.2 V at 10/1000 µs waveform, and exhibits ≤0.005 µA reverse leakage at VRWM, enabling robust ESD and surge protection in power rails.
For engineers reviewing the PTVS11VS1UR-QX datasheet, PTVS11VS1UR-QX pinout, PTVS11VS1UR-QX application, or PTVS11VS1UR-QX equivalent, this device is selected for AEC-Q101-compliant 12 V automotive systems requiring low-profile surface-mount TVS protection with precise 11 V standoff and sub-1 mm height.
Technical Context
This unidirectional TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its 11 V VRWM and clamping to ≤18.2 V at 22.0 A IPPM per IEC 61643-321 (10/1000 µs). Its breakdown voltage is specified at 12.2–13.5 V (VBR min/max) with IR = 1 mA test condition.
Thermally, it achieves 70 K/W Rth(j–sp) to solder point and supports junction temperatures up to 150 °C. Qualified to AEC-Q101, it withstands 30 kV contact/air discharge (IEC 61000-4-2) and 8 kV HBM, making it suitable for harsh automotive environments without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 11 V - stable reverse operating voltage before clamping begins; matches standard 12 V automotive supply rails. |
| VCL @ IPPM | ≤18.2 V at 22.0 A - maximum clamped voltage during 400 W transient, ensuring downstream ICs remain below absolute max ratings. |
| IPPM | 22.0 A - peak pulse current capability under 10/1000 µs waveform; defines surge energy handling (400 W). |
| IRM | ≤0.005 µA at VRWM - ultra-low leakage preserves battery life in always-on automotive modules. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount footprint with 1 mm max height for space-constrained PCB layouts. |
| AEC-Q101 | Qualified - certified for automotive use including temperature cycling, humidity, and mechanical stress per discrete semiconductor standard. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, cathode-marked with bar; dimensions 2.6 mm × 1.7 mm × 1.0 mm; optimized for reflow soldering with recommended stencil thickness 0.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal; carries full surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path; must be low-inductance to minimize VCL overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power rating | Enables protection against ISO 7637-2 Pulse 1/2a/5a surges in 12 V vehicle networks without thermal runaway. |
| 1 mm max package height | Allows placement under connectors or shields in compact ECUs and ADAS modules where Z-axis clearance is critical. |
| 0.005 µA max reverse leakage | Minimizes quiescent current draw in always-on domains (e.g., CAN wake-up circuits), extending battery standby time. |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for additional ESD protection on exposed ports like LIN or sensor inputs in body control modules. |
Applications
| Automotive Power Rail Protection | Body Control Module (BCM) Input Protection |
|---|---|
Use Scenario: 12 V battery-supplied microcontroller power input subjected to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between VCC and GND, triggered within nanoseconds of overvoltage event. Use Value: Clamps transients to ≤18.2 V while sustaining 22.0 A pulses, protecting 20 V-rated LDOs and MCU IOs without derating. |
Use Scenario: LIN bus transceiver power pin exposed to cable coupling and hot-swap noise in door module. IC Role / Device Role / Timing Role: Standoff protector maintaining 11 V nominal operation while suppressing fast ESD and slow surges. Use Value: Sub-1 mm height allows placement adjacent to connector; 0.005 µA leakage avoids compromising sleep current budgets. |
| Engine Control Unit (ECU) Sensor Supply Line | Infotainment System USB Power Input |
Use Scenario: 5 V sensor supply derived from 12 V rail, vulnerable to ignition-induced spikes in engine bay. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converter, absorbing energy before regulation stage. Use Value: 400 W rating handles repetitive ISO 7637-2 Pulse 5a events; AEC-Q101 qualification ensures reliability across -40 °C to +125 °C. |
Use Scenario: 5 V USB VBUS line in head unit connected to external accessories, subject to hot-plug and ESD. IC Role / Device Role / Timing Role: Secondary protection after primary fuse, clamping fast transients before USB controller IC. Use Value: 30 kV contact ESD rating eliminates need for extra TVS; SOD123W footprint fits tight routing near USB connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-Q | Same VRWM (11 V), but lower PPPM (400 W vs. SMAJ series' 400 W), higher VCL (18.2 V vs. 19.0 V), identical SOD-123 package. | Identical automotive qualification; slightly tighter VCL spec enables margin-critical 18 V-tolerant loads. | Select PTVS11VS1UR-QX when lowest possible clamping voltage and AEC-Q101 traceability are required. |
| TPSMA6L11A | Same VRWM (11 V), same SOD-123 package, but rated for 600 W PPPM and higher IPPM (33.3 A); VCL = 18.2 V. | Higher surge capacity suits heavy-duty commercial vehicles; not AEC-Q101 qualified - requires separate qualification effort. | Choose TPSMA6L11A only if system-level testing confirms need for >400 W surge margin and non-automotive qualification is acceptable. |
Compared with SMAJ11A-Q and TPSMA6L11A, PTVS11VS1UR-QX offers the tightest VCL specification (≤18.2 V), guaranteed AEC-Q101 compliance out-of-box, and lowest profile (1.0 mm height), making it optimal for space- and reliability-constrained automotive electronics.

FAQ
What is the clamping voltage of PTVS11VS1UR-QX at its rated peak pulse current?
The clamping voltage (VCL) is ≤18.2 V at 22.0 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures protected ICs remain within safe operating limits during surge events.
Is PTVS11VS1UR-QX suitable for 12 V automotive power supply lines?
Yes - its 11 V reverse standoff voltage (VRWM) aligns precisely with nominal 12 V automotive systems, allowing reliable operation during normal conditions while triggering rapidly during load dump or alternator transients. AEC-Q101 qualification confirms suitability for under-hood and cabin applications.
How does the SOD123W package benefit PCB layout in automotive modules?
The SOD123W package measures 2.6 mm × 1.7 mm × 1.0 mm with flat leads, enabling placement in dense areas such as near connectors or under shields. Its low 1 mm height prevents interference with mating components, and standardized reflow footprint simplifies manufacturing in high-reliability automotive assembly lines.
What ESD standards does PTVS11VS1UR-QX meet?
It meets IEC 61000-4-2 with 30 kV contact and 30 kV air discharge ratings, and MIL-STD-883 HBM with 8 kV rating. These levels exceed typical automotive requirements and eliminate the need for supplemental ESD protection on protected lines like LIN, CAN, or sensor inputs.
