Product details
Overview
PTVS14VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection with VRWM = 14 V, VBR = 15.6–17.2 V, and clamping voltage VCL = 23.2 V at IPPM = 25.9 A under 10/1000 µs waveform. It operates up to Tj = 185 °C and delivers ESD robustness of 30 kV (IEC 61000-4-2 contact discharge), suited for industrial power rail protection.
For engineers reviewing the PTVS14VP1UTP,115 datasheet, PTVS14VP1UTP,115 pinout, PTVS14VP1UTP,115 application, or PTVS14VP1UTP,115 equivalent, key selection criteria include its 14 V reverse standoff rating, 23.2 V clamping performance at 25.9 A, 1 mm profile for space-constrained PCB layouts, AEC-Q101 qualification status per revision history, and thermal resistance Rth(j-sp) = 12 K/W to solder point.
Technical Context
This unidirectional TVS diode uses a planar silicon junction optimized for fast response (<1 ns) to transient surges and stable clamping across temperature. Its breakdown voltage (VBR = 15.6–17.2 V) ensures reliable turn-on above 14 V standoff while maintaining low leakage (IRM ≤ 0.001 µA at VRWM).
The device's thermal design supports continuous operation at Tamb = −55 °C to +185 °C, enabled by low Rth(j-sp) = 12 K/W and junction-to-ambient resistance as low as 60 K/W on ceramic PCB. Its IEC 61643-321 compliant 10/1000 µs pulse handling (PPPM = 600 W) targets sustained surge immunity in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 15.6 V / 17.2 V - guaranteed breakdown range at IR = 1 mA, ensuring predictable turn-on margin |
| VCL @ IPPM | 23.2 V at 25.9 A - peak clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 600 W - rated peak pulse power per IEC 61643-321, defining surge energy absorption capability |
| IRM | ≤ 0.001 µA at VRWM - ultra-low reverse leakage preserves system standby current integrity |
| Tj max | 185 °C - extended junction temperature rating enables use in under-hood or high-power industrial enclosures |
| ESD rating | 30 kV contact discharge (IEC 61000-4-2) - protects against human-body and system-level electrostatic events |
Pinout & Package
PTVS14VP1UTP,115 is housed in a compact SOD128 (CFP5) surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm, with flat leads and cathode-marked bar for polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 14 V rail); marking bar identifies this terminal for correct orientation |
| 2 (A) | Anode | Connected to ground reference; forms unidirectional clamp path from rail to GND during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C and ambient to +185 °C - supports deployment in engine control units and industrial motor drives |
| Low-profile SMD package | 1.0 mm height - enables placement beneath heat sinks or in stacked board assemblies without mechanical interference |
| AEC-Q101 qualified | Qualified per revision history v.2 (20251201) - meets automotive-grade reliability for non-safety-critical subsystems |
| Thermal efficiency | Rth(j-sp) = 12 K/W - minimizes junction temperature rise during repeated transients via direct thermal path to solder joint |
| Low capacitance | ~100 pF at VR = 0 V (typical for 14 V variant) - avoids signal integrity degradation on medium-speed data or sensor lines |
Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | Lower PPPM (400 W), higher VCL (25.8 V at 23.3 A), SMC package (2.3 mm height) | Limited to ≤150 °C junction; not AEC-Q101 qualified per latest revision | Select when cost sensitivity outweighs thermal margin and automotive compliance needs |
| 1.5KE14A | Higher VCL (27.5 V at 21.8 A), axial lead TO-204AE package, no SMD footprint | Requires through-hole assembly; unsuitable for automated high-density PCB production | Choose only for legacy repair or prototyping where reflow compatibility is not required |
Compared with SMAJ14A and 1.5KE14A, PTVS14VP1UTP,115 offers superior thermal endurance (185 °C vs. 150 °C/175 °C), lower clamping voltage (23.2 V vs. 25.8 V/27.5 V), and SOD128 packaging enabling automated placement - critical for high-reliability industrial and automotive-adjacent designs.

FAQ
Is PTVS14VP1UTP,115 qualified for automotive applications?
Yes - per the revision history (v.2, 20251201), PTVS14VP1UTP,115 retains AEC-Q101 qualification. It is approved for automotive subsystems such as body control modules and infotainment power supplies, though not intended for safety-critical functions like airbag or braking systems.
What is the maximum allowable surge current for PTVS14VP1UTP,115?
The rated peak pulse current (IPPM) is 25.9 A under IEC 61643-321 10/1000 µs waveform conditions. This value is derived directly from VCL = 23.2 V and PPPM = 600 W (IPPM = PPPM / VCL). Exceeding this current risks permanent parametric shift or junction failure.
How does the 1 mm package height impact PCB layout?
The 1.0 mm SOD128 profile allows placement beneath adjacent components or heat spreaders, reduces board-level mechanical stress during thermal cycling, and supports conformal coating coverage without air gaps - making it ideal for compact, ruggedized industrial modules where vertical clearance is constrained.
Can PTVS14VP1UTP,115 replace older PTVS14Vxx variants?
Yes - PTVS14VP1UTP,115 supersedes prior PTVS14Vxx versions in the same SOD128 package with identical pinout, VRWM, and VCL. Key improvements include updated AEC-Q101 qualification status, tighter VBR tolerance (15.6–17.2 V), and verified 185 °C junction capability per latest datasheet revision.
