Product details
Overview
PTVS10VS1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection on DC power rails. It features 10 V reverse standoff voltage (VRWM), 17.0 V clamping voltage (VCL) at 2.5 A peak pulse current, and <0.005 µA reverse leakage at VRWM - enabling robust ESD and surge immunity in compact PCB layouts.
For engineers reviewing the PTVS10VS1UR-QX datasheet, PTVS10VS1UR-QX pinout, PTVS10VS1UR-QX application, or PTVS10VS1UR-QX equivalent, key selection criteria include its AEC-Q101 qualification, 1 mm profile for space-constrained automotive modules, IEC 61643-321 (10/1000 µs) compliance, and cathode-anode polarity marking for correct board-level orientation.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggering conduction when transient voltage exceeds its 10 V standoff threshold and limiting downstream voltage to ≤17.0 V under 2.5 A peak pulse current. Its junction-to-solder-point thermal resistance is 18 K/W, supporting reliable power dissipation in high-density automotive PCBs with minimal copper area.
The device uses silicon PN-junction avalanche breakdown for fast response (<1 ns), with electrostatic discharge ratings of ±30 kV (IEC 61000-4-2 contact/air) and ±8 kV (MIL-STD-883 HBM). It is rated for continuous operation up to 150 °C junction temperature and qualified per AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VCL @ IPPM | 17.0 V at 2.5 A - Clamped voltage during 10/1000 µs surge; ensures protected ICs see no more than 17 V. |
| PPPM | 400 W - Peak pulse power handling per IEC 61643-321; enables robust protection against ISO 7637-2 pulses. |
| IRM | <0.005 µA @ 10 V - Ultra-low leakage preserves battery life in always-on automotive circuits. |

Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment USB Port |
|---|---|
|
Use Scenario: Protects 12 V supply input of engine control unit against load dump and alternator transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS clamps surges above 10 V while maintaining low leakage during normal operation. Use Value: Limits voltage seen by downstream DC-DC converters to ≤17.0 V, preventing latch-up or damage to 24 V tolerant regulators. |
Use Scenario: Shields USB data/power lines in head unit against ESD and hot-plug transients during vehicle service. IC Role / Device Role / Timing Role: Fast-acting clamping diode placed between VBUS and GND, triggered within nanoseconds. Use Value: Withstands ±30 kV contact ESD without degradation, preserving signal integrity and preventing USB PHY reset. |
| Body Control Module (BCM) LIN Bus | ADAS Camera Power Rail |
|
Use Scenario: Guards LIN transceiver power pins against battery reversal and jump-start induced spikes in door modules. IC Role / Device Role / Timing Role: Reverse-polarity blocking and overvoltage clamp on 12 V supply line feeding LIN PHY. Use Value: Sub-µA leakage avoids parasitic drain on standby battery; 400 W rating handles sustained 100 ms transients. |
Use Scenario: Safeguards 5 V or 12 V camera module power input against ignition noise and cable discharge events. IC Role / Device Role / Timing Role: Primary front-end TVS on camera power rail, positioned before filtering and LDO stages. Use Value: 1 mm height fits beneath compact camera housings; AEC-Q101 qualification ensures field longevity in harsh thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-Q | Same VRWM (10 V), but lower PPPM (400 W vs. 400 W), higher VCL (18.2 V), and SMA package (2.5 mm height). | Less suitable for ultra-low-profile automotive modules due to 2.5 mm height and larger footprint. | Select if existing SMA footprint reuse is required and 1.2 V higher clamping is acceptable. |
| TPSMD10A | Higher VRWM tolerance (10% vs. 5%), same VCL (17.0 V), but not AEC-Q101 qualified and larger SMC package (7.1 mm length). | Not approved for automotive safety-critical systems; requires more PCB area and lacks automotive traceability. | Consider only for industrial non-automotive designs where qualification and size are secondary. |
Compared with SMAJ10A-Q and TPSMD10A, PTVS10VS1UR-QX delivers identical clamping performance in a 1 mm profile with full AEC-Q101 validation - making it the optimal choice for space- and qualification-constrained automotive power rail protection.

FAQ
What is the maximum clamping voltage of PTVS10VS1UR-QX under standard test conditions?
The clamping voltage (VCL) is 17.0 V measured at 2.5 A peak pulse current using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across temperature range and represents the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS10VS1UR-QX suitable for bidirectional transient protection?
No - PTVS10VS1UR-QX is a unidirectional TVS diode, intended for DC power rail protection where polarity is fixed. It conducts only when anode is negative relative to cathode; bidirectional protection requires a symmetric device like PTVS10VS1UR-Q (dual-diode configuration) or separate back-to-back arrangement.
How does the SOD123W package affect thermal performance in PCB layout?
The SOD123W package achieves 18 K/W junction-to-solder-point thermal resistance when mounted per Nexperia's recommended footprint (cathode pad ≥1 cm² on FR4). Its low 1 mm height limits convection cooling but enables efficient conductive heat transfer to underlying copper, especially with thermal vias under the cathode pad.
Does PTVS10VS1UR-QX require derating at elevated ambient temperatures?
Yes - peak pulse power must be derated above 25 °C ambient. At 125 °C, PPPM drops to approximately 240 W based on the 150 °C max junction temperature limit and thermal resistance data. Designers should consult Figure 6 in the Nexperia datasheet for precise derating curves and verify worst-case transient energy absorption.
