Product details
Overview
PTVS11VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 11 V reverse standoff voltage (VRWM), with clamping voltage VCL = 18.2 V at IPPM = 33.0 A and IRM ≤ 0.005 µA. It delivers AEC-Q101 qualification, 30 kV IEC 61000-4-2 ESD robustness, and 1 mm profile for space-constrained power rail protection.
For engineers reviewing the PTVS11VP1UP-QX datasheet, PTVS11VP1UP-QX pinout, PTVS11VP1UP-QX application, or PTVS11VP1UP-QX equivalent, key selection criteria include VRWM tolerance (±0.5 V), thermal resistance Rth(j-sp) = 12 K/W to solder point, junction temperature limit of 150 °C, and compliance with IEC 61643-321 10/1000 µs waveform testing.
Technical Context
This TVS diode operates as a unidirectional clamping device: under normal bias, it blocks current up to VRWM = 11 V with leakage <0.005 µA; during transients, it avalanches at VBR = 12.2–13.5 V (min–max) and clamps the line to ≤18.2 V at 33.0 A peak pulse current. Its SOD128 package enables low-inductance mounting critical for fast transient suppression.
The device adheres strictly to IEC 61643-321 (10/1000 µs waveform) for PPPM rating and supports automotive ambient ranges (−55 °C to +150 °C). Thermal performance is defined by Rth(j-a) = 60 K/W on ceramic PCB and Rth(j-sp) = 12 K/W - enabling high-power dissipation without heatsinking in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 11 V - maximum continuous reverse operating voltage before leakage exceeds 0.005 µA; defines safe operating margin for 12 V automotive systems. |
| VBR (min–max) | 12.2 V – 13.5 V - breakdown voltage range at 1 mA test current; ensures reliable avalanche initiation across process variation. |
| VCL @ IPPM | 18.2 V at 33.0 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress below 20 V threshold. |
| PPPM | 600 W - peak pulse power per IEC 61643-321; sustains 33 A surges without degradation in standard PCB layout. |
| IRM | ≤0.005 µA at VRWM - ultra-low leakage preserves battery life in always-on vehicle modules. |
| ESD Rating | 30 kV contact / 30 kV air per IEC 61000-4-2 - eliminates need for secondary ESD protection in infotainment and body control units. |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to cathode solder point; enables direct thermal coupling to copper pour for sustained pulse handling. |
Pinout & Package
PTVS11VP1UP-QX uses the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead geometry optimized for automated reflow and low-profile board assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side with bar; connects to protected line (e.g., 12 V rail); carries full surge current during clamping. |
| 2 (A) | Anode | Connects to ground reference; forms low-impedance path to shunt transient energy away from sensitive circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin environments including temperature cycling, humidity, and mechanical shock. |
| 1 mm package height | Enables placement beneath connectors or in tight stacking zones without interference with adjacent components or shields. |
| 600 W peak pulse power | Handles ISO 7637-2 Pulse 1 (−150 V/0.5 Ω) and Pulse 2a (+100 V/2 Ω) without failure in typical automotive harness configurations. |
| Low Rth(j-sp) = 12 K/W | Permits >90% of surge energy to dissipate directly into PCB copper, reducing localized heating and improving reliability at 10 Hz pulse repetition. |
| 30 kV ESD immunity | Eliminates need for external ESD diodes in USB, CAN, or LIN interface protection networks - simplifying BOM and layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower PPPM (400 W), higher VCL = 18.2 V at 24.7 A, non-AEC-Q101 rated. | Limited to industrial/commercial use; not qualified for automotive underhood deployment. | Select when cost sensitivity outweighs AEC-Q101 requirement and surge energy is ≤400 W. |
| SMCJ11A-Q | Same AEC-Q101 rating, but DO-214AB package (7.1 mm × 6.2 mm × 2.3 mm) - 7× larger footprint and 2.3× taller. | Requires more PCB area and cannot fit in space-constrained modules like mirror ECUs or sensor nodes. | Choose only if higher thermal mass is needed for repetitive surges beyond 1 Hz duty cycle. |
Compared with SMAJ11A and SMCJ11A-Q, PTVS11VP1UP-QX uniquely combines AEC-Q101 compliance, 600 W capability, and 1 mm height in SOD128 - making it the only option for next-gen automotive modules demanding both miniaturization and full automotive qualification.

FAQ
What is the maximum clamping voltage for PTVS11VP1UP-QX under standardized surge conditions?
The maximum clamping voltage (VCL) is 18.2 V at a peak pulse current (IPPM) of 33.0 A, measured per IEC 61643-321 using a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and represents the upper bound of voltage seen by downstream circuitry during worst-case transients.
Does PTVS11VP1UP-QX require derating at elevated ambient temperatures?
Yes - its rated peak pulse power (PPPM) decreases linearly above 25 °C junction temperature, with relative PPPM dropping to ~50% at 125 °C and ~25% at 150 °C (per Fig. 2). Designers must calculate actual junction temperature using Rth(j-a) = 60 K/W (ceramic PCB) or Rth(j-sp) = 12 K/W and apply appropriate derating to ensure safe operation under sustained thermal stress.
Can PTVS11VP1UP-QX be used in bidirectional signal line protection?
No - it is a unidirectional TVS diode intended only for DC power rail protection. Its anode-cathode polarity means it conducts only during negative transients on the cathode side. For bidirectional signal lines (e.g., CAN, USB D+/D−), a symmetric dual-diode array or dedicated bidirectional TVS such as PTVS3V3S1UR−QX is required.
How does the SOD128 package affect PCB layout and thermal performance?
The SOD128 (CFP5) package features a 3.8 mm × 2.6 mm footprint with a 1 mm height and integrated cathode tab - enabling direct thermal coupling to large copper pours. Its flat-lead design reduces parasitic inductance (<0.5 nH), critical for sub-ns response to fast transients, and allows placement in dense areas where height clearance is limited to ≤1.1 mm.
