Product details
Overview
PTVS5V0S1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage clamping on low-voltage DC rails. It features 5.0 V reverse standoff voltage (VRWM), 6.4–7.0 V breakdown voltage (VBR), 9.2 V clamping voltage (VCL) at 43.5 A peak pulse current (IPPM), and AEC-Q101 qualification for under-hood power supply protection.
For engineers reviewing the PTVS5V0S1UR-QX datasheet, PTVS5V0S1UR-QX pinout, PTVS5V0S1UR-QX application, or PTVS5V0S1UR-QX equivalent, this device is selected for robust ESD/ISO 7637-2 transient suppression in 5 V automotive subsystems where low clamping voltage, sub-1 mm profile, and high surge reliability are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when transient voltage exceeds VRWM = 5.0 V. Its junction structure delivers fast response (<1 ns) to 10/1000 µs surges per IEC 61643-321, with guaranteed clamping at ≤9.2 V up to IPPM = 43.5 A.
Thermal design is enabled by Rth(j-sp) = 18 K/W to cathode solder point and Rth(j-a) = 220 K/W on standard FR4 - supporting reliable operation at Tj ≤ 150 °C. AEC-Q101 qualification confirms performance across −55 °C to +150 °C ambient, including 30 kV IEC 61000-4-2 contact discharge immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/typ/max) | 6.4 / 6.7 / 7.0 V - Breakdown threshold range at 10 mA IR, defining turn-on consistency |
| VCL @ IPPM | 9.2 V - Clamped voltage during 43.5 A 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321, enabling high-energy transient absorption |
| IRM | 5 µA - Reverse leakage at VRWM, ensuring minimal quiescent power loss in 5 V systems |
| ESD Rating | 30 kV contact / 30 kV air per IEC 61000-4-2 - Full-system ESD hardening without external suppressors |
| Tj max | 150 °C - Junction temperature limit supporting under-hood deployment with thermal margin |
Pinout & Package

| 2 (A) | Anode | Connected to system ground; completes clamping loop during transient events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements - eliminates need for additional qualification effort |
| Low-profile SOD123W | 1.0 mm max height enables placement in space-constrained modules (e.g., ADAS ECUs, body control units) |
| 400 W peak pulse power | Handles ISO 7637-2 Pulse 1/2a/5a transients without degradation in 12 V/24 V vehicle architectures |
| 9.2 V clamping at 43.5 A | Protects 5 V logic supplies (e.g., MCU I/O, CAN transceivers) within safe voltage margins during load dump |
| 30 kV ESD immunity | Meets IEC 61000-4-2 Level 4 without external ESD components - reduces BOM count and layout area |
Applications
| Automotive Power Supply Protection | Body Control Module (BCM) I/O Protection |
|---|---|
Use Scenario: Suppressing load dump and alternator ripple on 5 V microcontroller power rails in engine control units. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between 5 V rail and chassis ground, activated within nanoseconds of overvoltage onset. Use Value: Limits rail voltage to ≤9.2 V during 43.5 A transients, preventing latch-up or permanent damage to 5 V LDOs and MCU cores. | Use Scenario: Protecting LIN bus transceiver inputs and sensor interface lines in door module assemblies. IC Role / Device Role / Timing Role: Low-leakage (5 µA) TVS on signal lines referenced to local 5 V supply, absorbing ESD and cable discharge events. Use Value: Maintains signal integrity during 30 kV contact ESD strikes while adding <0.1 µA standby current to battery-sensitive systems. |
| Infotainment System USB Port Protection | ADAS Camera Power Rail Clamp |
Use Scenario: Safeguarding 5 V VBUS line in vehicle-mounted USB charging ports against hot-plug surges and conducted noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on USB power input, positioned upstream of USB controller and port switch ICs. Use Value: Clamps 10/1000 µs surges to 9.2 V before they reach sensitive USB PHY circuitry, meeting USB-IF compliance requirements. | Use Scenario: Securing 5 V bias supply feeding image sensors and serializer ICs in rear-view camera modules. IC Role / Device Role / Timing Role: Compact-height TVS mounted directly at camera connector, minimizing trace inductance for optimal transient response. Use Value: 1.0 mm profile allows placement in tight camera housing; 400 W rating withstands repeated ignition-induced spikes without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-Q | Higher VCL = 9.6 V at 43.3 A; SMA package (2.5 mm height) | Less suitable for ultra-low-profile automotive modules due to 2.5× taller package | Select when legacy SMA footprint compatibility is required and height is not constrained |
| TPSMA6L5.0 | Lower PPPM = 600 W but higher VCL = 9.8 V; same SOD123W footprint | Higher clamping degrades margin for 5 V logic; better for 12 V+ rails | Prefer only if higher surge energy handling is prioritized over tight 5 V clamping margin |
Compared with SMAJ5.0A-Q and TPSMA6L5.0, PTVS5V0S1UR-QX delivers superior 5 V system protection via lower 9.2 V clamping and 1 mm height - critical for next-gen compact automotive electronics where both electrical margin and mechanical fit are non-negotiable.

FAQ
What is the maximum clamping voltage of PTVS5V0S1UR-QX under standardized surge conditions?
The maximum clamping voltage (VCL) is 9.2 V at 43.5 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across temperature and production lot, ensuring consistent protection margin for 5 V logic circuits during real-world transients like load dump and ISO 7637-2 pulses.
Does PTVS5V0S1UR-QX support bidirectional transient suppression?
No - PTVS5V0S1UR-QX is a unidirectional TVS diode, configured to clamp only positive transients on the cathode side relative to anode (ground). It is not rated for reverse-polarity or AC-line protection. For bidirectional applications, Nexperia offers the PTVS5V0S1UR-Q series' companion part PTVS5V0S1UH-Q, which uses a different internal structure.
How does the SOD123W package affect thermal performance in PCB layouts?
The SOD123W package achieves Rth(j-sp) = 18 K/W to the cathode solder point, enabling efficient heat transfer when the cathode pad is connected to ≥1 cm² copper pour. On standard FR4 with minimal copper, Rth(j-a) rises to 220 K/W - so thermal relief must be designed into the layout using thermal vias and ground plane coupling to sustain 400 W pulse duty cycles without exceeding 150 °C junction temperature.
Is PTVS5V0S1UR-QX compatible with lead-free reflow processes?
Yes - the device is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. The recommended reflow footprint (Nexperia doc sod123w_fr) specifies 0.1 mm stencil thickness and 1.2 mm × 1.4 mm solder lands per terminal, ensuring reliable wetting and mechanical strength without tombstoning or voiding.
