Product details
Overview
PTVS3V3P1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection with VRWM = 3.3 V, VBR = 5.2–6.0 V (min–max), VCL = 8.0 V at IPPM = 75 A, and Tj ≤ 185 °C. It serves as primary clamping protection on low-voltage DC power rails in industrial control modules.
For engineers reviewing the PTVS3V3P1UTP,115 datasheet, PTVS3V3P1UTP,115 pinout, PTVS3V3P1UTP,115 application, or PTVS3V3P1UTP,115 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, peak pulse current handling under IEC 61643-321 10/1000 μs waveform, thermal resistance to solder point (Rth(j-sp) = 12 K/W), and suitability for ambient temperatures up to +185 °C.
Technical Context
This TVS diode operates in avalanche breakdown mode during transients, delivering precise clamping at 8.0 V (typ) when subjected to 75 A peak pulse current (10/1000 μs). Its unidirectional configuration enables integration on positive-rail protection paths without reverse-bias leakage concerns beyond IRM = 5 μA at VRWM.
The device exhibits a negative temperature coefficient of breakdown voltage (SZ = −1.0 mV/K), ensuring stable clamping performance across −55 °C to +185 °C ambient. Its SOD128 package provides low thermal resistance to solder point (12 K/W), enabling reliable power dissipation in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Maximum continuous reverse operating voltage before significant leakage; sets minimum system rail margin for safe operation. |
| VBR (min–max) | 5.2–6.0 V - Breakdown onset range at 10 mA; defines earliest clamping activation threshold under surge conditions. |
| VCL @ IPPM | 8.0 V at 75 A - Clamped voltage during full-rated 600 W transient; must remain below protected IC absolute maximum rating. |
| PPPM | 600 W - Peak pulse power per IEC 61643-321 (10/1000 μs); determines survivability against standardized lightning/surge events. |
| Rth(j-sp) | 12 K/W - Thermal resistance from junction to cathode solder point; enables direct thermal coupling to copper pour for sustained pulse handling. |
| Tj max | 185 °C - Maximum junction temperature; supports operation in under-hood, motor drive, or furnace-control environments. |
| IRM | 5 μA - Reverse leakage at VRWM; ensures negligible standby current drain in battery-backed or ultra-low-power systems. |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for reflow soldering and minimal board height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; marking bar identifies this terminal; carries full surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance return path for transient energy; requires low-inductance PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Junction rated to 185 °C and ambient to +185 °C - eliminates derating in engine control units or industrial inverters. |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained modules where tall components interfere with enclosures or heatsinks. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard - validated for mechanical shock, temperature cycling, and HBM ESD (>8 kV). |
| Low clamping ratio | VCL/VRWM = 2.42 - tight voltage margin between standoff and clamping improves system-level surge immunity without overdesign. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - protects downstream circuitry from human-body and cable-discharge events. |
Applications
| Industrial Motor Drives | Programmable Logic Controllers (PLCs) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | Lower PPPM (400 W), higher VCL = 9.2 V at 32.4 A, Rth(j-a) = 60 K/W (vs. 12 K/W to solder point) | Limited to lower-energy transients; less effective in high-ambient thermal environments due to higher thermal resistance | Select when cost sensitivity outweighs thermal performance and peak power requirements are ≤400 W |
| SMCJ3.3A | Same 600 W rating but larger DO-214AB package (7.11 mm × 6.22 mm × 2.34 mm), VCL = 8.3 V at 72.3 A, Tj max = 175 °C | Requires more PCB area; not suitable for ultra-thin or height-constrained designs; lower max junction temperature | Select when board space permits and legacy DO-214AB footprint compatibility is required |
Compared with SMAJ3.3A and SMCJ3.3A, PTVS3V3P1UTP,115 delivers superior thermal management via its 12 K/W junction-to-solder-point path and maintains full 600 W capability in a 1 mm profile-critical for next-generation compact, high-temperature industrial modules.

FAQ
What is the maximum clamping voltage of PTVS3V3P1UTP,115 under rated surge conditions?
The maximum clamping voltage (VCL) is 8.0 V at a peak pulse current (IPPM) of 75 A, measured using the IEC 61643-321 10/1000 μs waveform. This value is confirmed in Table 7 of the datasheet and represents the upper bound of voltage seen by protected circuitry during full-rated 600 W transients.
Is PTVS3V3P1UTP,115 qualified for automotive use?
Yes-PTVS3V3P1UTP,115 is AEC-Q101 qualified per the revision history (v.2, December 2025), and the datasheet explicitly states qualification for automotive applications. It meets stress test requirements for discrete semiconductors including temperature cycling, humidity, and ESD.
How does the SOD128 package affect thermal performance compared to SMA or SMC packages?
The SOD128 (CFP5) package achieves Rth(j-sp) = 12 K/W-significantly lower than SMA (≈50 K/W) or SMC (≈30 K/W)-due to its flat, wide cathode tab directly soldered to large copper areas. This enables sustained 600 W pulse handling in high-ambient environments where traditional packages would exceed Tj limits.
Can PTVS3V3P1UTP,115 be used in bidirectional configurations?
No-it is a unidirectional TVS diode with anode and cathode terminals. Bidirectional protection requires either two devices in series opposition or a dedicated bidirectional part (e.g., PTVS3V3S1UTP). Using this part in reverse bias risks permanent conduction above VRWM due to its asymmetrical structure.
