Product details
Overview
PTVS5V0S1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features 5.0 V reverse standoff voltage (VRWM), 6.4–7.0 V breakdown voltage (VBR), 9.2 V clamping voltage (VCL) at 43.5 A peak pulse current (IPPM), and <5 µA reverse leakage at VRWM - deployed in industrial power supply protection circuits.
For engineers reviewing the PTVS5V0S1UR,115 datasheet, PTVS5V0S1UR,115 pinout, PTVS5V0S1UR,115 application, or PTVS5V0S1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (Rth(j-sp) = 18 K/W), AEC-Q101 qualification status, and compatibility with SOD123W footprint reflow profiles.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device in parallel with protected circuitry, conducting only when transient voltage exceeds its breakdown threshold. Its silicon avalanche structure enables fast response (<1 ns) and precise clamping with low dynamic impedance.
It complies with IEC 61643-321 for 10/1000 µs surge testing and supports operation across –55 °C to +150 °C junction temperature range. Thermal resistance from junction to solder point is 18 K/W, enabling effective heat dissipation in compact PCB layouts with standard cathode pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before significant leakage; sets minimum system rail margin. |
| VBR (min/typ/max) | 6.4 / 6.7 / 7.0 V at IR = 10 mA - Confirmed avalanche onset range ensures reliable triggering without premature conduction. |
| VCL | 9.2 V at IPPM = 43.5 A - Clamped voltage during 10/1000 µs surge defines maximum stress on downstream ICs. |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321 defines surge energy handling capability. |
| IRM | <5 µA at VRWM - Low leakage preserves efficiency in battery-backed or low-power standby circuits. |
| Rth(j-sp) | 18 K/W - Junction-to-solder-point thermal resistance enables direct thermal coupling to PCB copper for sustained surge duty. |
Pinout & Package
PTVS5V0S1UR,115 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 automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side with bar; connects to protected line (e.g., +5 V rail); carries surge current into ground path. |
| 2 (A) | Anode | Connects to system ground; completes clamping path during transient events; requires low-inductance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors - validated for automotive-grade reliability (per revision v.4, Dec 2025). |
| Low-profile SOD123W package | 1.0 mm max height enables use in space-constrained power modules and portable industrial controllers. |
| 400 W peak pulse power | Rated per IEC 61643-321 10/1000 µs waveform - supports EN 61000-4-5 Level 4 (4 kV) surge immunity in DC input stages. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM - protects against handling and system-level ESD events without external shielding. |
Applications
| Industrial Power Supply Protection | USB-C Power Delivery Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (larger: 4.5 × 2.7 × 2.2 mm); 400 W PPPM; VBR = 6.4–7.0 V; VCL = 9.2 V at 43.5 A - identical electrical specs but higher profile and thermal resistance. | Not suitable for ultra-thin designs; requires larger PCB footprint and has Rth(j-a) ≈ 50 K/W vs. 18 K/W for PTVS5V0S1UR. | Select when legacy DO-214AC layout exists or when higher mechanical robustness is prioritized over height constraint. |
| SMF5.0A | SOD-123 package (same outline but non-W variant); 200 W PPPM; VBR = 6.4–7.0 V; VCL = 9.2 V at 21.7 A - half the surge power rating and higher Rth(j-sp) (~25 K/W). | Limited to lower-energy transients (e.g., IEC 61000-4-4 EFT only); insufficient for full IEC 61000-4-5 Level 4 compliance. | Select only for cost-sensitive, non-automotive applications where 200 W surge margin is sufficient and height is not constrained. |
Compared with SMAJ5.0A and SMF5.0A, PTVS5V0S1UR,115 delivers identical clamping performance in a 1 mm low-profile SOD123W package with superior thermal coupling (18 K/W Rth(j-sp)) and full AEC-Q101 qualification - making it optimal for next-generation compact, automotive-qualified, and high-reliability industrial power rails.

FAQ
What is the maximum clamping voltage of PTVS5V0S1UR,115 under standard IEC 61643-321 test conditions?
The maximum clamping voltage (VCL) is 9.2 V at a peak pulse current (IPPM) of 43.5 A, measured using the 10/1000 µs current waveform defined in IEC 61643-321. This value is guaranteed across the operating temperature range and represents the upper limit of voltage seen by downstream circuitry during a full-rated surge event.
Is PTVS5V0S1UR,115 qualified for automotive applications per AEC-Q101?
Yes - according to the December 2025 revision (v.4) of the official Nexperia product data sheet, PTVS5V0S1UR,115 is explicitly listed among the 33 types upgraded to standard AEC-Q101 qualification status. This qualification covers stress testing for temperature cycling, humidity, HTRB, and ESD per the AEC-Q101 standard for discrete semiconductors.
How does the SOD123W package improve thermal performance compared to standard SOD-123?
The SOD123W variant features an extended cathode pad and optimized internal leadframe geometry, reducing junction-to-solder-point thermal resistance to 18 K/W - 28% lower than typical SOD-123 (≈25 K/W). This enables more efficient heat transfer to the PCB copper, supporting higher surge repetition rates and improved long-term reliability in thermally dense layouts.
Can PTVS5V0S1UR,115 be used in bidirectional configurations?
No - PTVS5V0S1UR,115 is a unidirectional TVS diode with cathode/anode polarity marked on the package. It conducts only during positive transients on the cathode side relative to anode. For bidirectional protection (e.g., AC lines or data lines), a dedicated bidirectional TVS such as PTVS5V0S1UTR or paired unidirectional devices are required.
