Product details
Overview
PTVS7V0P1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features 7.0 V reverse standoff voltage (VRWM), 12.0 V clamping voltage (VCL) at 50 A peak pulse current, and junction temperature rating up to 185 °C - enabling robust ESD and surge protection in engine control units and battery management systems.
For engineers reviewing the PTVS7V0P1UTP-QX datasheet, PTVS7V0P1UTP-QX pinout, PTVS7V0P1UTP-QX application, or PTVS7V0P1UTP-QX equivalent, key selection criteria include its 7.0 V VRWM tolerance, 50 A rated peak pulse current (IPPM), low 3 µA reverse leakage at VRWM, AEC-Q101 qualification, and thermal resistance of 12 K/W from junction to solder point - critical for under-hood automotive designs with limited heatsinking.
Technical Context
This unidirectional TVS diode operates as a clamping device: it remains high-impedance below 7.0 V VRWM, then rapidly avalanches above breakdown (VBR = 7.78–8.60 V) to limit transients to ≤12.0 V. Its IEC 61643-321 compliant 10/1000 µs waveform response ensures predictable clamping during load dump and ISO 7637-2 pulses.
Thermal design is enabled by ultra-low Rth(j-sp) = 12 K/W and stable performance up to Tj = 185 °C, supported by AEC-Q101 qualification including HBM ESD (8 kV), contact discharge (30 kV), and 100 A non-repetitive forward surge capability - making it suitable for permanent mounting on high-temperature PCBs without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 5 V–12 V rail protection. |
| VBR (min/typ/max) | 7.78 / 8.20 / 8.60 V at IR = 10 mA - Tight breakdown window ensures consistent turn-on across temperature and unit variation. |
| VCL @ IPPM | 12.0 V at 50 A - Clamping voltage limits energy dissipation in downstream ICs during 10/1000 µs surges. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321; enables protection against severe automotive load dump events. |
| IRM | 3 µA max at VRWM - Ultra-low leakage preserves battery life in always-on automotive modules. |
| Tj max | 185 °C - Enables direct placement near heat sources (e.g., power converters, motor drivers) without thermal derating. |
| Rth(j-sp) | 12 K/W - Junction-to-solder-point thermal resistance allows efficient heat transfer through cathode pad into PCB copper. |
Pinout & Package
PTVS7V0P1UTP-QX uses the CFP5 (SOD128) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated assembly and high-density layouts. The marking bar denotes the cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); clamping occurs when voltage exceeds VRWM relative to anode. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path for surge current during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard - eliminates need for additional qualification testing in Tier-1 designs. |
| 185 °C junction rating | Enables operation in under-hood environments (e.g., transmission control, ADAS sensors) without thermal throttling or derating. |
| 12 K/W Rth(j-sp) | Allows >90% of surge energy to dissipate directly into PCB copper via cathode pad - reduces reliance on external heatsinks. |
| 30 kV ESD immunity | Withstands IEC 61000-4-2 contact discharge - protects CAN/LIN interfaces and microcontroller I/O from assembly-line and field ESD events. |
| 1 mm package height | Minimizes board profile for space-constrained modules such as smart junction boxes and battery disconnect units. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Battery Management System (BMS) |
|---|---|

IC Role / Device Role / Timing Role: Secondary TVS after primary fuse and LC filter, placed adjacent to image sensor PMIC. Use Value: 1 mm height enables co-location with sensor ICs; 185 °C rating supports operation near lens actuators generating localized heat. |
Use Scenario: Protecting gate driver ICs and current sense amplifiers from inductive kickback during EPS motor commutation. IC Role / Device Role / Timing Role: Clamp device on 12 V auxiliary supply feeding half-bridge drivers and op-amps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS7V0S1UR | Same VRWM (7.0 V) and VCL (12.0 V), but lower PPPM (400 W) and no AEC-Q101 qualification. | Rated for industrial, not automotive, temperature range (Tj ≤ 150 °C). | Select only for cost-sensitive non-automotive applications where 400 W surge capacity suffices. |
| SMAJ7.0A-Q | Higher VCL (12.4 V), same VRWM, but larger SMA package (4.5 mm × 2.7 mm × 2.2 mm) and higher Rth(j-a) (50 K/W). | Lacks AEC-Q101 certification and 185 °C rating; requires more PCB area and thermal relief. | Use only if legacy SMA footprint must be retained and AEC compliance is not required. |
Compared with PTVS7V0P1UTP-QX, PTVS7V0S1UR offers lower surge robustness and no automotive qualification, while SMAJ7.0A-Q sacrifices thermal performance and board space efficiency - making the QX variant uniquely suited for high-reliability, space-constrained automotive power protection.

FAQ
What is the maximum clamping voltage of PTVS7V0P1UTP-QX at its rated peak pulse current?
The clamping voltage (VCL) is 12.0 V at 50 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream components see no more than 12.0 V during surge events.
Does PTVS7V0P1UTP-QX require derating at elevated ambient temperatures?
No derating is needed up to Tj = 185 °C, as confirmed by Nexperia's thermal characterization data showing stable PPPM performance across temperature (Fig. 2). The device maintains full 600 W rating at junction temperatures up to 185 °C, provided PCB thermal design achieves the specified Rth(j-sp) = 12 K/W.
How is polarity identified on the PTVS7V0P1UTP-QX package?
Polarity is marked by a white or black bar on the cathode end of the SOD128 body. Pin 1 (K) is the cathode and must be connected to the line being protected; Pin 2 (A) is the anode and connects to ground. This matches the graphic symbol and simplified outline in Nexperia's datasheet Figure 6.
Can PTVS7V0P1UTP-QX replace older TVS diodes like P6SMB7.0A in automotive designs?
Yes, but only after verifying layout compatibility: PTVS7V0P1UTP-QX uses SOD128 (3.8 mm × 2.6 mm), while P6SMB7.0A uses DO-214AA (4.5 mm × 3.2 mm). Electrical replacement is valid - both have 7.0 V VRWM and ~12 V VCL - but the QX offers superior thermal performance (Rth(j-sp) = 12 K/W vs. ~30 K/W) and AEC-Q101 qualification.
