Product details
Overview
PTVS54VS1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features VRWM = 54 V, VBR(min) = 60.0 V at IR = 1 mA, clamping voltage VCL = 87.1 V at IPPM = 4.6 A (10/1000 µs), and operates up to Tj = 185 °C - enabling use in industrial motor drives and under-hood automotive power modules.
For engineers reviewing the PTVS54VS1UTR,115 datasheet, PTVS54VS1UTR,115 pinout, PTVS54VS1UTR,115 application, or PTVS54VS1UTR,115 equivalent, key selection criteria include its 54 V standoff rating, 87.1 V clamping performance at 4.6 A, SOD123W thermal resistance (Rth(j-sp) = 18 K/W), and ESD robustness (30 kV contact discharge).
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transients above its reverse standoff voltage (VRWM = 54 V), with a guaranteed minimum breakdown voltage of 60.0 V at 1 mA test current. Its low leakage (IRM ≤ 0.001 µA at VRWM) ensures minimal standby power loss in protected circuits.
The device is rated for 400 W peak pulse power per IEC 61643-321 (10/1000 µs waveform) and maintains stable clamping up to junction temperatures of 185 °C - supported by a thermal resistance from junction to solder point of just 18 K/W when mounted on standard PCB footprints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 54 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V systems. |
| VBR (min) | 60.0 V at 1 mA - guaranteed avalanche initiation threshold; ensures predictable turn-on during surge events. |
| VCL | 87.1 V at IPPM = 4.6 A (10/1000 µs) - maximum clamped voltage seen by downstream circuitry during worst-case surge. |
| PPPM | 400 W - peak pulse power handling capability per IEC 61643-321; enables protection against high-energy transients like load dump. |
| Tj(max) | 185 °C - maximum junction temperature rating; supports operation in engine control units and industrial inverters without derating. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; enables efficient heat transfer into PCB copper for sustained surge duty. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides robust system-level ESD immunity without external shielding. |
Pinout & Package
PTVS54VS1UTR,115 is housed in a SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with a low-profile 1 mm height optimized for space-constrained layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 48 V rail); marking bar on package identifies this terminal. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 185 °C - eliminates thermal derating in under-hood or enclosed industrial enclosures. |
| Low-profile SMD package | SOD123W footprint (2.6 × 1.7 mm, 1.0 mm height) - fits dense PCB layouts and enables reflow compatibility without tombstoning. |
| Precision clamping tolerance | VBR range: 60.0–66.3 V (min–max) - tight 10.5% window ensures consistent surge response across production lots. |
| Ultra-low leakage | IRM ≤ 0.001 µA at VRWM - negligible standby current in always-on 48 V systems such as telematics or battery management. |
| Robust ESD immunity | 30 kV contact / >8 kV HBM - meets IEC 61000-4-2 Level 4 without additional board-level protection components. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

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 | Lower PPPM (400 W same), but higher VCL = 87.1 V → identical clamping; Rth(j-a) = 70 K/W vs. 18 K/W (j-sp) - less effective thermal coupling. | Designed for general-purpose FR4 boards without enhanced thermal pads; not qualified for 185 °C continuous operation. | Select SMAJ54A only for cost-sensitive, non-high-temp applications where solder-point thermal path optimization is not required. |
| SMCJ54A | Same VRWM/VCL, but larger DO-214AB package (7.11 × 6.22 mm) - 3× footprint area; PPPM = 1500 W, but derates to ~400 W at 100 °C ambient. | Used in legacy designs with manual assembly or high-surge legacy standards (e.g., MIL-STD-1275); incompatible with fine-pitch SMT lines. | Choose SMCJ54A only if system-level testing requires >1500 W single-pulse headroom and board space permits larger footprint. |
Compared with SMAJ54A and SMCJ54A, PTVS54VS1UTR,115 delivers superior thermal performance (18 K/W j-sp) and full 185 °C junction rating in a 2.6 × 1.7 mm footprint - making it optimal for next-gen 48 V systems where size, temperature, and reliability are co-constrained.

FAQ
What is the maximum clamping voltage of PTVS54VS1UTR,115 under standardized surge conditions?
The maximum clamping voltage (VCL) is 87.1 V at a peak pulse current (IPPM) of 4.6 A, measured using the IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C junction), ensuring consistent protection behavior in high-temperature deployments.
Can PTVS54VS1UTR,115 be used in automotive applications?
Yes - PTVS54VS1UTR,115 is qualified for under-hood and powertrain-adjacent applications due to its 185 °C junction rating, 30 kV ESD immunity, and stable clamping up to Tj = 185 °C. While not AEC-Q200 certified, its electrical and thermal specs meet functional requirements for 48 V mild-hybrid systems and body electronics exposed to high ambient temperatures.
How does the SOD123W package improve thermal performance compared to standard SMA/SMB packages?
The SOD123W (CFP3) package features an exposed cathode tab that reduces thermal resistance from junction to solder point (Rth(j-sp) = 18 K/W), versus ~70 K/W for typical SMA packages. This allows faster heat dissipation into the PCB copper, sustaining repeated 400 W surges without thermal runaway - critical for compact, sealed industrial enclosures.
Is the marking code 'D1' on the device body sufficient for full identification?
Yes - per Nexperia's marking table, 'D1' uniquely identifies PTVS54VS1UTR,115 within the PTVSxS1UTR series. The marking bar adjacent to pin 1 confirms cathode orientation, and the absence of additional codes indicates standard tape-and-reel packaging (115 = reel size designation per ordering info).
