Product details
Overview
PTVS17VS1UTR-QX from Nexperia is a unidirectional 400 W transient voltage suppressor (TVS) diode in SOD123W (CFP3) package, designed for high-temperature automotive and industrial overvoltage protection. It features VRWM = 17 V, VBR(min) = 18.9 V at 1 mA, VCL = 27.6 V at IPPM = 14.5 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS17VS1UTR-QX datasheet, PTVS17VS1UTR-QX pinout, PTVS17VS1UTR-QX application, or PTVS17VS1UTR-QX equivalent, this page delivers verified electrical specs, thermal performance data, AEC-Q101 qualification status, and real-world clamping behavior under IEC 61643-321 surge conditions.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for fast response (<1 ns) to transients and stable clamping across −55 °C to +185 °C junction temperature. Its unidirectional configuration provides low-leakage reverse blocking (IRM ≤ 0.001 µA at VRWM) with precise breakdown threshold control.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2 (contact/air discharge). Thermal resistance Rth(j-sp) = 18 K/W enables reliable power dissipation when mounted on cathode solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 18.9 V at 1 mA - guaranteed minimum breakdown voltage ensures predictable turn-on margin |
| VCL | 27.6 V at IPPM = 14.5 A - peak clamped voltage limits downstream IC stress during 10/1000 µs surge |
| PPPM | 400 W - rated peak pulse power defines maximum transient energy absorption capability |
| IRM | 0.001 µA at VRWM - ultra-low leakage preserves system standby current in battery-powered modules |
| Tj max | 185 °C - extended junction temperature rating supports under-hood and powertrain applications |
| AEC-Q101 | Qualified - certified for automotive use per stress test requirements for discrete semiconductors |
Pinout & Package
PTVS17VS1UTR-QX is housed in a SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm with flat leads and 0.75 mm lead pitch. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (A) | Anode | Connected to line or signal input requiring transient suppression; reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation up to Tj = 185 °C - enables placement near power converters and engine control units |
| Low-profile packaging | 1.0 mm height - allows routing under connectors and in space-constrained PCB layouts |
| Automotive qualification | AEC-Q101 compliant - meets reliability and stress-test requirements for automotive electronics |
| ESD robustness | 30 kV contact/air discharge per IEC 61000-4-2 - protects against human-body and system-level electrostatic events |
| Thermal efficiency | Rth(j-sp) = 18 K/W - minimizes junction temperature rise during repetitive surges when soldered to copper pad |

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 | Lower PPPM (400 W same), but higher VCL = 29.2 V at same IPPM; Rth(j-a) = 70 K/W vs. 18 K/W to solder point | Less effective thermal coupling in high-power density layouts; not AEC-Q101 qualified | Prefer PTVS17VS1UTR-QX where board space, thermal performance, or automotive compliance is critical |
| 1.5SMC17A-Q | Higher package volume (DO-214AB), VCL = 27.6 V identical, but IPPM = 14.5 A same; Tj max = 175 °C vs. 185 °C | Requires larger PCB footprint; unsuitable for under-hood locations exceeding 175 °C ambient | Choose PTVS17VS1UTR-QX for compact SMD designs needing full 185 °C junction rating |
Compared with SMAJ17A-Q and 1.5SMC17A-Q, PTVS17VS1UTR-QX offers superior thermal interface (Rth(j-sp) = 18 K/W), AEC-Q101 qualification, and 10 °C higher junction temperature limit - enabling denser, more reliable protection in automotive powertrain and industrial motor control systems.

FAQ
What is the clamping voltage of PTVS17VS1UTR-QX at its rated peak pulse current?
The clamping voltage VCL is 27.6 V measured at IPPM = 14.5 A under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream components see no more than 27.6 V during surge events.
Does PTVS17VS1UTR-QX meet automotive qualification standards?
Yes - it is fully qualified to AEC-Q101 for stress testing of discrete semiconductors and explicitly recommended for automotive applications. The qualification covers temperature cycling, humidity bias, ESD, and mechanical shock tests required for under-hood and powertrain use.
How does the SOD123W package affect thermal performance compared to larger TVS packages?
The SOD123W package delivers Rth(j-sp) = 18 K/W to the cathode solder point - significantly lower than typical SMA or DO-214AB packages - due to its optimized copper tab geometry and low-profile thermal path. This enables efficient heat transfer into PCB copper even in compact layouts.
Can PTVS17VS1UTR-QX be used in bidirectional protection configurations?
No - it is a unidirectional TVS diode intended for DC line protection where polarity is fixed. For bidirectional AC or data-line protection, a dedicated bidirectional variant (e.g., PTVS17VS1UTR-QY) or back-to-back diode arrangement is required.
