Product details
Overview
PTVS54VS1UTR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 54 V, VBR(min) = 60.0 V at 1 mA, VCL = 87.1 V at IPPM = 4.6 A (10/1000 μs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS54VS1UTR-QX datasheet, PTVS54VS1UTR-QX pinout, PTVS54VS1UTR-QX application, or PTVS54VS1UTR-QX equivalent, this device supports AEC-Q101-compliant automotive ECU power input protection, high-reliability industrial SMPS clamping, and high-temperature battery management system surge suppression.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for stable breakdown behavior across −55 °C to +185 °C junction temperature. Its unidirectional configuration provides low clamping voltage during reverse-biased transients while maintaining <0.001 µA IRM at VRWM.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2. Thermal resistance Rth(j-sp) is 18 K/W to solder point, enabling robust pulse energy dissipation in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 54 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 60.0 V at 1 mA - Guaranteed breakdown onset ensures precise overvoltage threshold control |
| VCL | 87.1 V at IPPM = 4.6 A - Low clamping voltage limits downstream IC stress during 10/1000 µs surges |
| PPPM | 400 W - Peak pulse power rating defines maximum transient energy absorption capability |
| IRM | 0.001 µA - Ultra-low leakage preserves battery life and signal integrity in always-on circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A-Q | Lower PPPM (400 W same), but VRWM = 54 V, VCL = 87.1 V; SMA package (4.5 mm × 2.7 mm × 2.3 mm) | Larger footprint and 2.3 mm height limit routing density in compact automotive modules | Select when legacy SMA layout exists and height constraint is not critical |
| TPSMD54A | Same VRWM/VCL, but Tj max = 175 °C and no AEC-Q101 qualification | Not approved for automotive safety-critical systems per OEM requirements | Acceptable for industrial power supplies where AEC-Q101 is not mandated |
Compared with SMAJ54A-Q and TPSMD54A, PTVS54VS1UTR-QX uniquely combines AEC-Q101 qualification, 185 °C junction rating, and 1.0 mm profile-enabling direct integration into next-generation automotive ECUs where thermal margin, space, and compliance are co-constrained.

FAQ
What is the clamping voltage of PTVS54VS1UTR-QX at its rated peak pulse current?
The clamping voltage VCL is 87.1 V measured at IPPM = 4.6 A using the standardized 10/1000 µs current waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and defines the maximum voltage seen by downstream circuitry during surge events.
Does PTVS54VS1UTR-QX support bidirectional transient suppression?
No. PTVS54VS1UTR-QX is a unidirectional TVS diode, configured with cathode (pin 1) and anode (pin 2). It conducts only during reverse-biased overvoltage events and must be oriented with cathode toward the protected positive rail. Bidirectional variants are not offered in the PTVSxS1UTR-Q series.
How does the 185 °C junction rating impact PCB layout and thermal design?
The 185 °C Tj max allows uninterrupted operation in high-ambient zones such as engine compartments. Layout must ensure Rth(j-sp) ≤ 18 K/W via adequate copper pour on the cathode pad (≥1 cm² recommended), as specified in Nexperia's thermal characterization data for FR4 boards.
Is PTVS54VS1UTR-QX compatible with standard SOD123W footprints?
Yes. It uses the industry-standard CFP3 (SOD123W) outline with 2.6 mm × 1.7 mm body and 0.9–1.1 mm height. The recommended reflow footprint matches JEDEC MS-012AC, including 1.2 mm × 1.4 mm solder lands and 0.1 mm stencil thickness for optimal solder joint reliability.
