Product details
Overview
PTVS6V0S1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection at 6.0 V reverse standoff voltage. It delivers 38.8 A peak pulse current (IPPM), clamps transients to ≤10.3 V at rated current, and exhibits ≤5 µA reverse leakage at VRWM, enabling robust ESD and surge protection in power rails.
For engineers reviewing the PTVS6V0S1UR-QX datasheet, PTVS6V0S1UR-QX pinout, PTVS6V0S1UR-QX application, or PTVS6V0S1UR-QX equivalent, key selection criteria include its AEC-Q101 qualification, 1 mm profile for space-constrained PCBs, 10/1000 µs IEC 61643-321 compliance, and cathode-marked polarity for correct orientation in DC bias protection circuits.
Technical Context
This unidirectional TVS operates as a clamping device: under normal bias (≤6.0 V), it presents high impedance with <5 µA leakage; during transient events exceeding breakdown voltage (6.67–7.37 V), it avalanches to limit voltage across protected circuitry. Its junction-to-solder-point thermal resistance is 18 K/W, supporting reliable power dissipation in automotive ambient conditions up to 150 °C.
The device uses silicon planar technology with controlled avalanche characteristics, qualified per AEC-Q101 stress tests including HBM ESD (8 kV), contact/air discharge (30 kV), and non-repetitive forward surge (50 A, 8.3 ms). Its SOD123W footprint enables automated placement while maintaining low inductance for fast response (<1 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.0 V - Maximum continuous reverse operating voltage before significant leakage; defines minimum system rail tolerance margin. |
| VBR (min/typ/max) | 6.67 / 7.02 / 7.37 V - Breakdown onset range at 10 mA; ensures predictable clamping initiation across temperature and process variation. |
| VCL @ IPPM | 10.3 V - Clamped voltage at 38.8 A peak pulse; determines maximum stress on downstream ICs during 10/1000 µs surge. |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321; validates energy absorption capability for automotive load-dump and ISO 7637-2 pulses. |
| IRM | 5 µA - Reverse leakage at VRWM; ensures minimal standby current drain in always-on vehicle subsystems. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount outline with cathode marking bar; supports high-density layout and reflow compatibility. |
| AEC-Q101 | Qualified - Certified for automotive discrete semiconductors; covers temperature cycling, humidity, mechanical shock, and ESD robustness. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, 1.0 mm height, cathode indicated by molded marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs from anode to cathode during overvoltage. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to shunt surge current away from sensitive loads. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 certified for under-hood and infotainment systems requiring long-term reliability in harsh thermal and ESD environments. |
| Low-profile packaging | 1.0 mm max height enables use in ultra-thin modules (e.g., ADAS camera ECUs) without interfering with shield cans or connectors. |
| High ESD immunity | 30 kV air/contact discharge (IEC 61000-4-2) and 8 kV HBM ensure resilience against assembly handling and in-vehicle electrostatic events. |
| Precision clamping | Tight VBR tolerance (±5% typical) and low VCL/VRWM ratio (1.72×) minimize voltage overshoot during fast transients. |
| Thermal performance | 18 K/W junction-to-solder-point resistance allows sustained operation at 150 °C ambient when mounted per recommended footprint. |
Applications
| Automotive Power Rail Protection | Infotainment System ESD Guarding |

Use Scenario: Protecting 12 V battery-fed microcontroller power inputs against ISO 7637-2 pulse 1 (inductive switch-off) and pulse 3a/b (load dump). IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between VCC and GND, responding within nanoseconds to suppress spikes above 10.3 V. Use Value: Prevents latch-up or permanent damage to 5 V/3.3 V LDOs and MCU IOs by limiting transient voltage to safe levels without affecting steady-state regulation. |
Use Scenario: Shielding USB 2.0, HDMI, or LVDS interfaces in head units from human-body-model ESD events during connector insertion. IC Role / Device Role / Timing Role: Low-capacitance TVS on signal lines referenced to local ground, leveraging fast avalanche turn-on to divert 8–30 kV discharges. Use Value: Maintains signal integrity with negligible parasitic capacitance while meeting IEC 61000-4-2 Level 4 immunity requirements without adding series impedance. |
| Industrial Sensor Node Power Input | Telematics Module CAN Bus Protection |
|
Use Scenario: Safeguarding 24 V supply inputs of wireless sensor nodes exposed to field wiring surges and lightning-induced coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main DC input, coordinated with upstream fuse and downstream LC filtering. Use Value: Absorbs 400 W transients without degradation, enabling single-stage protection architecture that reduces BOM count and board area. |
Use Scenario: Protecting CAN_H/CAN_L differential pair in telematics control units against battery reverse connection and jump-start transients. IC Role / Device Role / Timing Role: Dual unidirectional TVS array (one per line) referenced to chassis ground, clamping common-mode overvoltages. Use Value: Ensures CAN physical layer remains functional after 10/1000 µs surges up to ±50 V, preserving communication integrity during vehicle service events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-Q | Same VRWM (6.0 V), but lower PPPM (400 W vs. SMAJ series' 400 W), higher VCL (10.5 V), and larger SMA package (4.5 × 2.7 mm). | Less suitable for ultra-thin automotive modules due to 2.2 mm height; requires more PCB area. | Select when legacy SMA footprint compatibility is required and height constraints are relaxed. |
| TPSMD6.0A | Higher VRWM tolerance (6.0–6.67 V), same VCL (10.3 V), but not AEC-Q101 qualified; Rth(j-a) = 40 K/W vs. 70 K/W for PTVS6V0S1UR-QX. | Not approved for automotive production; limited thermal performance in high-ambient environments. | Acceptable only for industrial prototypes where AEC-Q101 is not mandated and thermal margins exceed 40 °C. |
Compared with SMAJ6.0A-Q and TPSMD6.0A, PTVS6V0S1UR-QX offers superior volumetric efficiency (1.0 mm height), guaranteed automotive qualification, and tighter thermal resistance control-making it optimal for space- and reliability-critical vehicle electronics.

FAQ
What is the maximum clamping voltage of PTVS6V0S1UR-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 10.3 V at 38.8 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value ensures downstream components see no more than 10.3 V during surge events, protecting 5 V and 3.3 V logic interfaces when used with appropriate series impedance.
How does the SOD123W package affect PCB layout and thermal design?
The SOD123W package measures 2.6 × 1.7 × 1.0 mm with a cathode-marked bar, enabling high-density routing and compatibility with standard reflow profiles. Its 18 K/W junction-to-solder-point thermal resistance requires adherence to Nexperia's recommended 4.4 × 2.9 mm copper pad layout (per Fig. 4) to maintain junction temperature below 150 °C under 400 W pulse conditions.
Is PTVS6V0S1UR-QX suitable for bidirectional transient protection?
No-PTVS6V0S1UR-QX is unidirectional and conducts only during reverse-biased overvoltage events. For bidirectional protection (e.g., AC lines or data buses), a symmetric TVS like PTVS6V0S1UR-Q (dual-diode configuration) or separate back-to-back devices are required. Using this part on AC signals risks forward conduction and failure.
What AEC-Q101 test conditions validate its automotive suitability?
PTVS6V0S1UR-QX passes AEC-Q101 stress tests including temperature cycling (−65 °C to +150 °C, 1000 cycles), high-temperature operating life (1000 h at 150 °C), ESD (HBM 8 kV, IEC 61000-4-2 ±30 kV), and surge (50 A, 8.3 ms half-sine). These confirm reliability in engine bay and cabin environments across vehicle lifecycles.
