Product details
Overview
PTVS26VS1UR,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 VRWM = 26 V, VBR(min) = 28.9 V, VCL(max) = 42.1 V at IPPM = 9.5 A (10/1000 μs), and IRM ≤ 0.1 μA, targeting protection of 24 V industrial power supplies against IEC 61000-4-5 surges.
For engineers reviewing the PTVS26VS1UR,115 datasheet, PTVS26VS1UR,115 pinout, PTVS26VS1UR,115 application, or PTVS26VS1UR,115 equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current capability under 10/1000 μs waveform, thermal resistance to PCB (Rth(j-sp) = 18 K/W), and AEC-Q101 qualification status per revision history.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche diode, triggering when transient voltage exceeds its 26 V standoff threshold. Its breakdown occurs at minimum 28.9 V (1 mA test current), with clamping limited to 42.1 V at 9.5 A peak pulse, ensuring protected circuitry remains below safe operating limits during surge events.
It complies with IEC 61643-321 for 10/1000 μs waveform testing and supports ESD immunity up to 30 kV (IEC 61000-4-2 contact discharge). Junction temperature is rated to 150 °C, and thermal performance is optimized via low-profile SOD123W package with direct cathode solder-point thermal path (Rth(j-sp) = 18 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 26 V - maximum continuous reverse working voltage before leakage rises above 0.1 µA |
| VBR (min) | 28.9 V - guaranteed avalanche initiation voltage at 1 mA, defining turn-on threshold |
| VCL (max) | 42.1 V - worst-case clamped voltage at 9.5 A peak pulse, limiting stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321 (10/1000 µs), enabling robust surge immunity |
| IRM | ≤ 0.1 µA - ultra-low reverse leakage at VRWM, minimizing standby power loss in battery systems |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point, critical for sustained surge duty cycling |
Pinout & Package
PTVS26VS1UR,115 uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +24 V rail); clamping occurs when voltage exceeds VRWM relative to anode |
| 2 (A) | Anode | Typically tied to ground or low-impedance return path; completes conduction path during transient |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse rating | Enables single-device protection against severe IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V lines |
| 1 mm package height | Allows placement beneath low-profile connectors or shields without mechanical interference |
| AEC-Q101 qualified (per revision v.4) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| 0.1 µA max IRM at VRWM | Reduces quiescent current drain in always-on 24 V systems such as telematics or sensor nodes |
Applications
| Industrial Power Rail Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 24 V DC input of PLC I/O modules against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V rail and chassis ground, clamping within 1 ns to limit voltage excursion. Use Value: VCL = 42.1 V ensures microcontrollers and interface ICs remain below absolute maximum ratings during 10/1000 µs surges up to 400 W. | Use Scenario: Safeguarding LIN bus power supply pins in door module ECUs exposed to battery disconnection spikes. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing energy from ISO 7637-2 Pulse 5a (load dump) events on 24 V supply lines. Use Value: AEC-Q101 qualification and 150 °C Tj rating support operation in under-hood environments with minimal derating. |
| Factory Automation Sensor Interface | Telecom Remote Power Feeder |
Use Scenario: Shielding 24 V fieldbus-powered sensors (e.g., IO-Link devices) from cable-induced surges in factory floors. IC Role / Device Role / Timing Role: Primary overvoltage clamp on VDD line, coordinated with upstream fuse and downstream LDO. Use Value: Low Rth(j-sp) = 18 K/W enables rapid heat dissipation into PCB copper, sustaining repeated surge events without thermal runaway. | Use Scenario: Protecting PoE-like 24–48 V remote power feeders in outdoor telecom cabinets from lightning-induced surges. IC Role / Device Role / Timing Role: First-line transient suppressor on DC input prior to DC-DC converter and monitoring circuitry. Use Value: 30 kV ESD rating (IEC 61000-4-2) prevents latch-up or damage during field maintenance handling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A | Lower PPPM = 400 W but higher VCL = 42.8 V at same IPPM; SMA package (larger footprint, higher Rth(j-a)) | Less suitable for space-constrained 2-layer PCBs due to 4.5 mm × 2.7 mm body vs. SOD123W's 2.6 mm × 1.7 mm | Select when legacy SMA footprint compatibility is required and thermal budget allows higher Rth(j-a) ≈ 70 K/W |
| 1.5SMC27A | Higher VRWM = 27 V, VCL = 43.5 V at 9.2 A; DO-214AB package, 50 % larger volume | Not AEC-Q101 qualified; intended for commercial/industrial use only | Choose where automotive qualification is unnecessary and board area permits larger package |
Compared with SMAJ26A and 1.5SMC27A, PTVS26VS1UR,115 delivers identical surge power rating in a 58 % smaller footprint, lower thermal resistance to solder point, and verified AEC-Q101 compliance-making it optimal for compact, thermally demanding, or automotive-qualified 24 V designs.

FAQ
What is the maximum clamping voltage of PTVS26VS1UR,115 under standard IEC 61643-321 test conditions?
The maximum clamping voltage (VCL) is 42.1 V at IPPM = 9.5 A for a 10/1000 μs current waveform, measured at Tj = 25 °C. This value is guaranteed across temperature and represents the worst-case voltage seen by protected circuitry during a full-rated surge event.
Is PTVS26VS1UR,115 qualified for automotive applications per AEC-Q101?
Yes-per Revision v.4 (December 2025) of the official Nexperia datasheet, PTVS26VS1UR,115 is explicitly listed among the 33 types upgraded to standard AEC-Q101 qualification, covering temperature cycling, HTRB, and ESD stress tests required for automotive use.
How does the SOD123W package affect thermal performance compared to standard SOD-123?
The SOD123W (CFP3) package features a wider cathode pad and optimized internal leadframe, reducing Rth(j-sp) to 18 K/W-versus ~30–40 K/W for standard SOD-123. This enables faster heat transfer to the PCB solder joint, improving surge repetition capability and long-term reliability under cyclic stress.
Can PTVS26VS1UR,115 be used in bidirectional configurations?
No-it is strictly unidirectional. The device conducts only when cathode voltage exceeds anode by ≥VBR; it blocks in forward bias like a standard diode. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., PTVS26VS1UR,115's symmetrical counterpart) must be selected.
