Product details
Overview
PTVS26VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection with VRWM = 26 V, VBR(min) = 28.9 V, VCL = 42.1 V at IPPM = 14.3 A, and junction temperature rating up to 185 °C. It serves as primary clamping protection on DC power rails in industrial power supplies and high-ambient-temperature control modules.
For engineers reviewing the PTVS26VP1UTP,115 datasheet, PTVS26VP1UTP,115 pinout, PTVS26VP1UTP,115 application, or PTVS26VP1UTP,115 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, thermal resistance to PCB (Rth(j-sp) = 12 K/W), peak pulse current capability under 10/1000 µs waveform, and compatibility with reflow soldering footprints per Fig. 7.
Technical Context
This TVS diode operates in avalanche breakdown mode during transients, delivering precise clamping at 42.1 V when subjected to 14.3 A peak pulse current (10/1000 µs). Its unidirectional configuration enables placement anode-to-ground for positive-going surge suppression on supply lines.
Designed for stable operation up to Tj = 185 °C, it maintains rated PPPM = 600 W across ambient temperatures from −55 °C to +185 °C, with reverse leakage IRM ≤ 0.001 µA at VRWM and temperature coefficient SZ = 29.1 mV/K - enabling predictable voltage drift in thermal cycling environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 26 V - maximum continuous reverse operating voltage before significant leakage; defines upper limit of protected rail voltage |
| VBR (min) | 28.9 V - minimum breakdown voltage at 1 mA; ensures reliable conduction onset above normal operating voltage |
| VCL | 42.1 V - clamped voltage at 14.3 A peak pulse; determines maximum stress imposed on downstream circuitry |
| PPPM | 600 W - peak pulse power handling (10/1000 µs); defines transient energy absorption capacity |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to cathode solder point; critical for sustained power dissipation in compact layouts |
| IRM | ≤ 0.001 µA - reverse leakage at VRWM; ensures negligible standby current in always-on systems |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides robust system-level ESD immunity without external shielding |
Pinout & Package
PTVS26VP1UTP,115 uses the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated assembly and thermal transfer via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected supply rail; marking bar identifies this terminal; primary heat path to PCB |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during positive transients |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rating up to 185 °C enables use in engine bay, motor drive, and industrial oven control circuits |
| Low-profile SMD package | 1.0 mm height allows integration into space-constrained PCBs without interfering with adjacent components or enclosures |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors; supports automotive-grade reliability requirements |
| Low clamping ratio | VCL/VBR = 42.1/28.9 ≈ 1.46 - tight voltage margin preserves headroom for downstream 3.3 V or 5 V logic ICs |
| Controlled thermal path | Rth(j-sp) = 12 K/W to cathode solder point enables effective heat extraction using standard FR4 PCB copper pours |
Applications
| Industrial Power Supply Protection | Motor Drive Control Module |

Use Value: Maintains <0.001 µA leakage at VRWM and stable VBR across −40 °C to +85 °C, preventing false triggering in battery-backed operation. |
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), higher VCL (45.7 V), Rth(j-a) = 60 K/W (vs. 12 K/W to solder point) | Limited to lower-energy transients; less suitable for sustained high-temp operation due to inferior thermal coupling | Select when cost sensitivity outweighs thermal performance and clamping precision |
| SMCJ26A | Same VRWM/VCL but larger SMC package (7.1 mm × 6.2 mm × 2.6 mm); PPPM = 1500 W; Rth(j-a) = 19 K/W | Better energy handling but 2.6× footprint and 2.6× height; incompatible with ultra-thin designs | Choose for high-energy surge zones where board space and height allow larger package |
Compared with SMAJ26A and SMCJ26A, PTVS26VP1UTP,115 uniquely balances 600 W pulse power, 1 mm profile, and 12 K/W junction-to-solder-point thermal resistance - making it optimal for thermally dense, height-restricted industrial and automotive control modules requiring repeatable clamping at elevated temperatures.

FAQ
What is the maximum clamping voltage of PTVS26VP1UTP,115 under standard test conditions?
The maximum clamping voltage (VCL) is 42.1 V at a peak pulse current (IPPM) of 14.3 A, measured using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and defines the highest voltage seen by downstream components during a surge event.
Is PTVS26VP1UTP,115 qualified for automotive applications?
Yes - PTVS26VP1UTP,115 is AEC-Q101 qualified per Nexperia's revision history (v.2, Dec 2025), confirming stress-test compliance for discrete semiconductors in automotive environments. However, it is not intended for safety-critical systems such as airbag controllers or brake ECUs unless explicitly validated by the end customer.
How does the thermal resistance of PTVS26VP1UTP,115 compare to standard SMA/SMB packages?
PTVS26VP1UTP,115 achieves Rth(j-sp) = 12 K/W to the cathode solder point - significantly lower than typical SMA (≈35 K/W) or SMB (≈25 K/W) packages - due to its flat-lead SOD128 construction and direct thermal path through the cathode tab to PCB copper, enabling higher sustained power handling in compact layouts.
Can PTVS26VP1UTP,115 be used in bidirectional configurations?
No - PTVS26VP1UTP,115 is a unidirectional TVS diode with cathode (K) and anode (A) terminals. It conducts only during positive transients on the cathode side. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part like PTVS26VS1UTP must be selected.
