Product details
Overview
PTVS8V0S1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection at 8.0 V reverse standoff voltage. It delivers 29.4 A peak pulse current (IPPM), clamps transients to 13.6 V (VCL), and exhibits only 0.03 µA reverse leakage at VRWM - enabling robust ESD and surge protection in space-constrained PCB layouts.
For engineers reviewing the PTVS8V0S1UR-QX datasheet, PTVS8V0S1UR-QX pinout, PTVS8V0S1UR-QX application, or PTVS8V0S1UR-QX equivalent, key selection criteria include its AEC-Q101 qualification, 1 mm profile, 10/1000 µs IEC 61643-321 compliance, and cathode-anode polarity marking for correct orientation in DC power rail protection circuits.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds 8.0 V (VRWM). Its 8.89–9.83 V breakdown range (VBR) ensures reliable turn-on before system damage, while the 13.6 V clamping voltage (VCL) limits downstream IC stress during 29.4 A transient events.
Thermally, it sustains 150 °C junction temperature and achieves 70 K/W Rth(j-a) on ceramic PCBs. Its 30 kV IEC 61000-4-2 contact discharge rating and 8 kV HBM ESD tolerance confirm suitability for harsh automotive environments where load dump and ISO 7637-2 pulses occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/typ/max) | 8.89 / 9.36 / 9.83 V - Ensures predictable avalanche onset across temperature and unit variation |
| VCL @ IPPM | 13.6 V - Clamped voltage during 29.4 A 10/1000 µs surge, defining protected circuit's max stress level |
| IPPM | 29.4 A - Peak surge current capability under standardized IEC 61643-321 waveform |
| IRM | 0.03 µA - Ultra-low leakage preserves battery life and avoids false triggering in low-power systems |
| PPPM | 400 W - Peak pulse power handling capacity, confirming robustness against repetitive transients |
| ESD Rating | 30 kV contact / 30 kV air (IEC 61000-4-2); 8 kV HBM - Validated immunity for assembly and field operation |
Pinout & Package
The PTVS8V0S1UR-QX uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, and cathode-bar marking for polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +12 V rail); marked by bar on top surface |
| 2 (A) | Anode | Connected to ground reference; defines unidirectional conduction path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard - enables deployment in engine control, infotainment, and ADAS modules without requalification |
| 1 mm package height | Enables placement under connectors or near edge-mounted components where Z-axis clearance is constrained |
| 400 W peak pulse power | Supports high-energy transients like ISO 7637-2 Pulse 5a (load dump) without degradation |
| SOD123W footprint | Standardized 2-pad layout compatible with automated reflow and wave soldering per Nexperia's published land patterns |
| 0.03 µA IRM at VRWM | Minimizes quiescent current drain in always-on vehicle subsystems such as CAN wake-up receivers |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in body control modules against load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between battery input and DC-DC converter input stage. Use Value: Limits voltage to ≤13.6 V during 29.4 A transients, preventing damage to downstream LDOs and microcontrollers rated for 16 V absolute max. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) connected to long harnesses in factory automation equipment. IC Role / Device Role / Timing Role: Local TVS at connector entry point, shunting ESD and inductive switching noise to chassis ground. Use Value: 30 kV contact ESD rating and 0.03 µA leakage preserve signal integrity and avoid offset drift in precision 24-bit ADC front-ends. |
| Automotive Infotainment USB Port | Smart Lighting DC Bus Protection |
Use Scenario: Protecting USB VBUS line in head-unit applications exposed to hot-plug and cable-induced transients. IC Role / Device Role / Timing Role: Standoff-clamp TVS mounted directly at USB Type-A receptacle, anode tied to system ground. Use Value: 8.0 V VRWM aligns with 5 V nominal bus while allowing margin for ripple; 13.6 V clamping prevents USB PHY latch-up. | Use Scenario: Securing constant-current LED driver inputs in exterior lighting modules subjected to alternator ripple and load dump. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12–24 V input rail upstream of buck controller and MOSFET switch. Use Value: 400 W PPPM handles repeated 100 ms load dump events per ISO 16750-2 without derating or thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-Q | Same VRWM (8.0 V), but SMA package (4.5 mm × 2.7 mm × 2.2 mm); 400 W PPPM; VCL = 13.6 V; IPPM = 29.4 A | Larger footprint and 2.2 mm height - unsuitable for ultra-thin automotive modules | Select when board space allows larger package and legacy SMA land patterns exist |
| TPSMD8.0A | DO-214AB package; VRWM = 8.0 V; VCL = 13.6 V; IPPM = 29.4 A; same 400 W rating but no AEC-Q101 certification | Not qualified for automotive use; higher Rth(j-a) due to larger thermal mass | Acceptable for industrial or consumer applications where AEC-Q101 is not mandated |
Compared with SMAJ8.0A-Q and TPSMD8.0A, PTVS8V0S1UR-QX offers identical electrical clamping performance but uniquely combines AEC-Q101 qualification, 1 mm height, and SOD123W manufacturability - making it the optimal choice for next-generation automotive ECUs requiring miniaturization and automotive compliance.

FAQ
What is the maximum junction temperature rating for PTVS8V0S1UR-QX?
The device is rated for a maximum junction temperature (Tj) of 150 °C, validated per IEC 60134 limiting values. This allows operation in under-hood automotive environments where ambient temperatures reach 125 °C and power dissipation remains within safe thermal limits due to its 70 K/W Rth(j-a) on ceramic substrates.
Does PTVS8V0S1UR-QX support bidirectional transient suppression?
No - PTVS8V0S1UR-QX is strictly unidirectional. Its cathode-anode configuration clamps only reverse-polarity transients on positive rails. For AC or dual-rail protection, a separate bidirectional variant (e.g., PTVS8V0S1UR-QB) or back-to-back diode arrangement is required.
How is polarity identified on the PTVS8V0S1UR-QX package?
Polarity is indicated by a marking bar on the top surface of the SOD123W package, aligned with Pin 1 (cathode). This matches the graphic symbol in Nexperia's datasheet Figure 2 and ensures correct orientation during pick-and-place and visual inspection.
Is PTVS8V0S1UR-QX compatible with lead-free reflow soldering processes?
Yes - the device is qualified for lead-free reflow per J-STD-020. Nexperia specifies a maximum peak temperature of 260 °C for 30 seconds, and provides detailed solder land patterns for both reflow (Figure 4) and wave soldering (Figure 5) in the datasheet to ensure reliable joint formation without delamination or voiding.
