Product details
Overview
PTVS17VS1UR-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 17 V reverse standoff voltage (VRWM), 20.9 V maximum clamping voltage (VCL) at 14.5 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - enabling robust ESD and surge immunity in compact PCB layouts.
For engineers reviewing the PTVS17VS1UR-QX datasheet, PTVS17VS1UR-QX pinout, PTVS17VS1UR-QX application, or PTVS17VS1UR-QX equivalent, key selection criteria include 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 PCB orientation during assembly.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when transient voltage exceeds its 17 V VRWM threshold. Its 19.9 V typical breakdown voltage (VBR) ensures precise turn-on timing before downstream ICs experience overstress.
Thermal design relies on low Rth(j-sp) of 18 K/W to solder point and 70 K/W to ceramic PCB, supporting sustained 400 W pulse handling under IEC 61643-321 waveform conditions. The SOD123W package's 2.6 mm × 1.7 mm footprint enables high-density placement near connectors or power inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 18.9 V - Minimum breakdown voltage at 1 mA, ensuring reliable turn-on margin above VRWM |
| VCL (max) | 20.9 V - Maximum clamped voltage at 14.5 A IPPM, limiting stress on protected circuitry |
| IPPM | 14.5 A - Peak pulse current capability under 10/1000 µs waveform per IEC 61643-321 |
| IRM | 0.001 µA - Reverse leakage at VRWM, minimizing standby power loss in battery-critical systems |
| PPPM | 400 W - Rated peak pulse power, defining energy-handling capacity for transient suppression |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air) - Enables direct interface with exposed automotive ports without external ESD staging |
Pinout & Package
The PTVS17VS1UR-QX uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, 1 mm max height, flat leads optimized for reflow soldering. Cathode identification is via a visible marking bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A-Q | Same VRWM (17 V), but SMA package (4.5 mm × 2.7 mm); 350 W PPPM rating | Larger footprint and lower power handling; less suitable for ultra-thin automotive modules | Select when legacy SMA layout exists and 350 W pulse energy suffices |
| TPSMF17A | 17 V VRWM, 400 W PPPM, but SOD-123FL package with gull-wing leads; 22.5 V VCL at 14.5 A | Higher clamping voltage increases protected IC stress; not AEC-Q101 qualified | Use only in non-automotive industrial designs where AEC compliance is not required |
Compared with SMAJ17A-Q and TPSMF17A, PTVS17VS1UR-QX delivers identical 17 V standoff and 400 W pulse rating in a 30% smaller footprint, with AEC-Q101 validation and lower 20.9 V clamping - making it optimal for next-generation automotive ECUs where space, reliability, and low clamping are jointly critical.

FAQ
What is the maximum clamping voltage for PTVS17VS1UR-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 20.9 V at 14.5 A peak pulse current (IPPM), measured under the IEC 61643-321 10/1000 µs waveform. This value ensures protected downstream components remain within their absolute maximum voltage ratings during surge events.
Is PTVS17VS1UR-QX suitable for bidirectional transient protection?
No - PTVS17VS1UR-QX is a unidirectional TVS diode, intended for DC circuits with defined polarity. It conducts only during reverse overvoltage conditions (anode positive relative to cathode). For AC or bidirectional signal lines, a dedicated bidirectional variant like PTVS17VS1UR-Q (dual-diode configuration) must be used.
How does the SOD123W package affect thermal performance compared to larger packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W to solder point and Rth(j-a) = 70 K/W on ceramic PCB, enabling effective heat transfer despite its 1 mm height. Its low thermal resistance supports repeated 400 W pulse handling when mounted per Nexperia's recommended footprint with adequate copper pour on cathode pad.
Does PTVS17VS1UR-QX require external current-limiting components in series?
No external current-limiting resistor is required for basic clamping function, but one is recommended in high-energy surge scenarios (e.g., ISO 7637-2 Pulse 5a) to reduce IPPM magnitude and extend device lifetime. Typical values range from 0.5 Ω to 5 Ω depending on system impedance and pulse duration.
