Product details
Overview
PTVS7V0S1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection at 7.0 V reverse standoff voltage. It delivers 33.3 A peak pulse current (IPPM), clamps transients to ≤12.0 V at 33.3 A, and exhibits ≤3 µA reverse leakage at VRWM, with AEC-Q101 qualification for under-hood power rail protection.
For engineers reviewing the PTVS7V0S1UR-QX datasheet, PTVS7V0S1UR-QX pinout, PTVS7V0S1UR-QX application, or PTVS7V0S1UR-QX equivalent, key selection criteria include clamping voltage (VCL = 12.0 V), breakdown voltage range (VBR = 7.78–8.60 V), thermal resistance (Rth(j-a) = 220 K/W on FR4), and automotive qualification status - all critical for robust 12 V system ESD/surge hardening.
Technical Context
This unidirectional TVS diode operates as a clamping device in series with the protected line, conducting only during overvoltage events above its breakdown threshold. Its silicon avalanche structure enables fast response (<1 ns) to transients per IEC 61643-321 (10/1000 μs waveform) and sustains 400 W peak pulse power without degradation.
The device features low-profile SOD123W packaging (1.0 mm height, 2.6 × 1.7 mm footprint) with cathode-marked polarity and is rated for junction temperatures up to 150 °C. It meets IEC 61000-4-2 (±30 kV contact/air discharge) and MIL-STD-883 HBM (8 kV), supporting harsh automotive ambient conditions (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - Maximum continuous reverse operating voltage before significant leakage; sets minimum system operating margin for 12 V nominal rails. |
| VBR (min/typ/max) | 7.78 / 8.20 / 8.60 V @ IR = 10 mA - Confirmed avalanche onset range ensures reliable triggering across temperature and process variation. |
| VCL @ IPPM | 12.0 V @ 33.3 A - Clamping voltage defines worst-case voltage seen by downstream ICs during surge; critical for 5 V/3.3 V logic survival. |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321 (10/1000 μs); determines survivability against ISO 7637-2 Pulse 1/2/5a/b surges. |
| IRM | ≤3 µA @ VRWM - Ultra-low leakage preserves battery life in always-on automotive modules and avoids false triggers in high-impedance sensing paths. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount outline with cathode marking bar; optimized for automated placement and reflow compatibility. |
| AEC-Q101 | Qualified - Validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and temperature cycling; supports PPAP documentation. |
Pinout & Package
SOD123W (CFP3) is a 2-terminal surface-mount plastic package with 1.0 mm maximum height, 2.6 mm length, and 1.7 mm width. The cathode is marked by a visible bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V supply rail); polarity must match forward-biased clamp direction toward ground. |
| 2 (A) | Anode | Connected to circuit ground reference; forms low-impedance shunt path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power rating | Enables compliance with ISO 7637-2 Pulse 5a (50 V/100 ms) and Pulse 5b (100 V/400 ms) without derating in compact layout. |
| 12.0 V clamping voltage at 33.3 A | Protects downstream 12 V-rated CAN transceivers, LIN controllers, and MCU I/O pins from destructive overvoltage exposure. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance. |
| 0.001 µA typical reverse leakage | Minimizes standby current drain in always-on vehicle networks (e.g., door module wake-up circuits), extending battery life. |
| 1.0 mm profile SOD123W package | Reduces PCB real estate and thermal mass while maintaining mechanical robustness for vibration-prone under-hood mounting. |
Applications
| Automotive Power Rail Protection | CAN/LIN Bus Line Protection |
|---|---|
|
Use Scenario: 12 V battery-supplied ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground to limit transient excursions. Use Value: Clamps ISO 7637-2 Pulse 5a to ≤12.0 V, preventing damage to PMICs and microcontrollers rated for 16 V absolute max. |
Use Scenario: High-speed CAN FD or LIN physical layer interfaces in vehicle networking. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional TVS shields bus lines from negative-going spikes on VCC-coupled nodes. Use Value: Sub-1 ns response and 33.3 A surge handling suppress ESD events (IEC 61000-4-2 ±30 kV) without signal distortion. |
| Industrial Sensor Power Conditioning | Automotive Lighting Driver Input Stage |
|
Use Scenario: 24 V industrial sensors powered via long cables susceptible to induced lightning surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp at DC input stage of analog front-end or signal conditioner ICs. Use Value: 400 W PPPM rating allows single-device protection against 1 kV/500 A surge waveforms per IEC 61000-4-5 (10/1000 μs). |
Use Scenario: LED headlamp drivers receiving switched 12 V input subject to back-EMF from relay coils and motor loads. IC Role / Device Role / Timing Role: Fast-acting shunt element absorbing inductive kickback energy before it reaches driver MOSFETs or gate drivers. Use Value: Low clamping voltage (12.0 V) prevents gate oxide overstress on 20 V-rated high-side switches in constant-current LED controllers. |
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 same), higher VCL (12.5 V), larger SMA package (4.5 × 2.7 mm), non-AEC-Q101. | Lacks automotive qualification; suitable for industrial/commercial boards where space and qualification are secondary. | Select when cost sensitivity outweighs AEC-Q101 requirement and board area permits larger footprint. |
| PTVS7V0S1UR | Identical electrical specs but non-automotive grade; no AEC-Q101 validation; same SOD123W package and marking (A5). | Not qualified for automotive use; limited to consumer or industrial applications with lower reliability demands. | Choose only for non-automotive designs where qualification documentation is unnecessary and cost is prioritized. |
Compared with SMAJ7.0A-Q and PTVS7V0S1UR, the PTVS7V0S1UR-QX uniquely combines AEC-Q101 qualification, 12.0 V clamping, and ultra-compact SOD123W packaging - making it the sole option for space-constrained, safety-critical automotive power rail protection.

FAQ
What is the maximum clamping voltage of PTVS7V0S1UR-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 12.0 V at 33.3 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 μs waveform. This value is guaranteed across temperature and process variation and defines the upper voltage limit imposed on protected circuitry during surge events.
Does PTVS7V0S1UR-QX support bidirectional transient suppression?
No - PTVS7V0S1UR-QX is a unidirectional TVS diode, configured to clamp only positive transients relative to ground. It conducts when the cathode (pin 1) is driven >12.0 V above anode (pin 2). For bidirectional protection, two devices in series-opposing configuration or a dedicated bidirectional TVS (e.g., PTVS7V0S1UR-QB) would be required.
How does the SOD123W package affect thermal performance in PCB layout?
The SOD123W package has Rth(j-a) = 220 K/W on standard FR4 with single-sided copper, meaning 1 °C rise per 4.5 mW dissipated. To improve thermal relief, increase cathode pad area to 1 cm² (reducing Rth(j-a) to 130 K/W) or use ceramic substrates (70 K/W), especially in high-duty-cycle surge environments.
Is PTVS7V0S1UR-QX compatible with lead-free reflow soldering profiles?
Yes - the device is qualified for lead-free reflow per JEDEC J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s pre- and post-peak. The SOD123W footprint (Fig. 4) specifies 0.1 mm stencil thickness and 1.2 × 1.4 mm solder lands for optimal wetting and void control.
