Product details
Overview
PTVS7V0S1UTR-Q 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 VRWM = 7.0 V, VBR = 7.78–8.60 V (min–max at 10 mA), clamping voltage VCL = 12.0 V at IPPM = 33.3 A, and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS7V0S1UTR-Q datasheet, PTVS7V0S1UTR-Q pinout, PTVS7V0S1UTR-Q application, or PTVS7V0S1UTR-Q equivalent, this device is selected for robust ESD/ISO 7637-2 surge suppression in 12 V automotive subsystems where low-profile mounting and AEC-Q101 qualification are mandatory.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-anode polarity, triggered when reverse voltage exceeds VRWM = 7.0 V. Its breakdown occurs between 7.78 V and 8.60 V at 10 mA, delivering precise overvoltage threshold control for sensitive 12 V supply lines.
It sustains 400 W peak pulse power per IEC 61643-321 (10/1000 µs waveform), supports 30 kV contact ESD per IEC 61000-4-2, and maintains stable clamping performance up to Tj = 185 °C - enabled by high-temperature silicon design and qualified AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V reverse standoff voltage - defines maximum continuous operating voltage before clamping begins |
| VBR (min–max) | 7.78–8.60 V at 10 mA - ensures reliable turn-on margin above nominal 12 V rail with tolerance |
| VCL | 12.0 V at IPPM = 33.3 A - limits downstream voltage during 400 W surge to safe levels for 12 V ICs |
| PPPM | 400 W (10/1000 µs) - handles ISO 7637-2 Pulse 1 & 2a transients in automotive ECUs without failure |
| IRM | 3 µA max at VRWM - negligible leakage current preserves battery life in always-on vehicle modules |
| Tj max | 185 °C - enables placement near hot components (e.g., power converters, engine control units) |
| Package | SOD123W (CFP3): 2.6 × 1.7 × 1.0 mm - ultra-low profile for space-constrained PCB layouts |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package with 2 terminals, 1.0 mm height, and cathode-marked bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground reference; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use via full stress test suite including HTGB, HTRB, and ESD |
| High-temperature operation | Junction rated to 185 °C - eliminates derating concerns in under-hood or powertrain applications |
| Low-profile SMD package | 1.0 mm height - fits beneath shields and in tight board-to-board spacing without interference |
| 30 kV ESD immunity | Contact discharge per IEC 61000-4-2 - protects against human handling and assembly-stage ESD |
| Stable clamping at elevated Tj | VCL drift < ±5 % from 25 °C to 150 °C - ensures predictable protection across full operating range |
Applications
| Automotive Body Control Module (BCM) | Engine Control Unit (ECU) Power Input |
|---|---|
|
Use Scenario: Protects 12 V supply input of BCM against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamps surges >12 V while remaining non-conductive during normal operation. Use Value: Prevents latch-up or damage to MCU and CAN transceivers during ISO 7637-2 Pulse 5a events. |
Use Scenario: Shields ECU microcontroller power domain from battery transients during cold-crank and jump-start. IC Role / Device Role / Timing Role: Fast-response clamping element placed directly at power entry point before bulk capacitance. Use Value: Limits VCC spike to ≤12.0 V at 33.3 A, preserving 5 V LDO input integrity and avoiding brownout resets. |
| ADAS Camera Power Rail | Electric Power Steering (EPS) Sensor Interface |
|
Use Scenario: Guards 12 V input to image sensor module exposed to harness-induced transients in front-end camera systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power feed, positioned upstream of DC-DC converter. Use Value: Maintains uninterrupted imaging function by suppressing 100 V/10 ms pulses without thermal runaway (Tj ≤ 185 °C). |
Use Scenario: Protects torque and position sensor signal conditioning circuitry powered from EPS 12 V bus. IC Role / Device Role / Timing Role: Low-leakage (3 µA) TVS prevents DC offset errors in precision analog front-end during standby. Use Value: Enables fail-safe operation by surviving repeated 400 W surges while maintaining <0.1 % baseline error in sensor output. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A-Q | Lower PPPM = 400 W but VRWM = 7.0 V, VCL = 12.5 V, Tj max = 150 °C | Lacks AEC-Q101 qualification; not rated for under-hood ambient >125 °C | Select only for non-automotive industrial use where junction temperature stays below 150 °C |
| TPSMA6L7.0A | Same VRWM/VCL, but PPPM = 600 W, Tj max = 175 °C, no AEC-Q101 documentation | Higher surge capacity but unverified for automotive qualification; footprint differs (SMA) | Use only if higher pulse energy is required and AEC-Q101 compliance is not mandated |
Compared with SMAJ7.0A-Q and TPSMA6L7.0A, PTVS7V0S1UTR-Q uniquely combines AEC-Q101 certification, 185 °C junction rating, and SOD123W low-profile packaging - making it the only option qualified for direct placement on high-temperature automotive power rails requiring zero derating.

FAQ
What is the maximum clamping voltage of PTVS7V0S1UTR-Q at its rated peak pulse current?
The clamping voltage VCL is 12.0 V measured at IPPM = 33.3 A 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 ensures downstream 12 V ICs remain within absolute maximum ratings during surge events.
Is PTVS7V0S1UTR-Q compatible with lead-free reflow soldering processes?
Yes - the SOD123W package is qualified for standard lead-free reflow profiles with peak temperatures up to 260 °C. The recommended stencil thickness is 0.1 mm, and the footprint matches JEDEC MS-012AC, enabling compatibility with automated SMT assembly lines used in automotive electronics manufacturing.
How does the 185 °C junction rating impact layout and thermal design?
The 185 °C Tj max allows placement adjacent to heat-generating components (e.g., MOSFETs, DC-DC inductors) without thermal derating. Designers may use minimal copper pour (standard FR4 single-sided pad) since Rth(j-a) remains ≤220 K/W, eliminating need for thermal vias or large heatsinks in most automotive PCB implementations.
Does PTVS7V0S1UTR-Q support bidirectional transient suppression?
No - it is strictly unidirectional. The device conducts only when reverse-biased beyond VRWM = 7.0 V. For AC or dual-polarity signal lines, a separate bidirectional TVS (e.g., PTVS7V0S1UTR-Q's complementary series) or back-to-back configuration is required; this part must be oriented with cathode toward the protected line.
