Product details
Overview
PTVS12VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection with VRWM = 12 V, VBR = 13.3–14.7 V, VCL = 19.9 V at IPPM = 30.2 A, and Tj ≤ 185 °C - deployed in industrial power supply rails and high-reliability DC input stages.
For engineers reviewing the PTVS12VP1UTP,115 datasheet, PTVS12VP1UTP,115 pinout, PTVS12VP1UTP,115 application, or PTVS12VP1UTP,115 equivalent, this device delivers verified clamping performance under IEC 61643-321 10/1000 μs surges, supports reflow/wave soldering per SOD128 footprint, and maintains stable leakage (IRM ≤ 2.5 μA) up to 150 °C junction temperature.
Technical Context
This unidirectional TVS diode operates as a clamping device in reverse-biased configuration, triggering at breakdown voltage (VBR) to divert surge current away from sensitive downstream circuitry. Its low Rth(j-sp) = 12 K/W enables effective thermal coupling to PCB copper, critical for sustained operation at Tamb up to 185 °C.
The device complies with IEC 61643-321 for 10/1000 μs waveform testing and achieves 30 kV ESD immunity (IEC 61000-4-2 contact discharge). Its temperature coefficient SZ = +10.3 mV/K ensures predictable VBR drift across operating range, supporting robust design margining in thermally aggressive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail voltage ceiling. |
| VBR (min/typ/max) | 13.3 / 14.0 / 14.7 V at IR = 1 mA - precise breakdown threshold ensuring reliable turn-on during transients. |
| VCL @ IPPM | 19.9 V at 30.2 A - clamped voltage seen by protected circuit during full-rated 600 W surge. |
| IRM | ≤ 2.5 μA at VRWM - ultra-low leakage preserves efficiency in battery-backed or low-power systems. |
| Tj max | 185 °C - enables deployment in engine bay, industrial motor drives, and other high-ambient zones without derating. |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to cathode solder point; enables direct thermal path to PCB copper pour. |
| ESD rating | 30 kV contact discharge (IEC 61000-4-2) - eliminates need for additional ESD front-end protection in many designs. |
Pinout & Package
PTVS12VP1UTP,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 dissipation.
| 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 or low-impedance return path; forms the reference node for reverse-biased clamping operation. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Rated per IEC 61643-321 (10/1000 μs), enabling protection against severe lightning-induced or inductive-switching transients. |
| 185 °C junction rating | Supports uninterrupted operation in under-hood automotive modules, industrial inverters, and high-temp power converters without thermal shutdown. |
| SOD128 package height | 1.0 mm max - allows use in space-constrained applications including portable medical devices and compact power adapters. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors; suitable for automotive subsystems where specified. |
| Low clamping ratio | VCL/VBR = 1.42 - tight voltage control minimizes stress on downstream ICs while maintaining fast response time. |
Applications
| Industrial Power Supply Protection | DC Motor Drive Input Stage |
|---|---|
|
Use Scenario: 24 V DC industrial PLC power input subjected to load dump and inductive kickback.

IC Role / Device Role / Timing Role: Reverse-biased TVS on motor supply rail to absorb regenerative energy spikes before they reach MOSFET drivers. Use Value: Maintains VCL ≤ 19.9 V at 30.2 A, protecting 3.3 V logic interfaces and preventing false triggering of fault circuits. |
| High-Temperature Sensor Interface | Telecom DC Feeder Line |
|
Use Scenario: Temperature sensor module mounted near exhaust manifold in vehicle diagnostics system. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V bias line feeding analog front-end, operating continuously at Tamb = 150 °C.

Use Value: Withstands repeated 10/1000 μs surges up to 600 W while maintaining low capacitance (< 100 pF at 12 V) to avoid signal integrity degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Lower PPPM (400 W), higher VCL (20.9 V at 24.7 A), SMA package (Rth(j-a) ≈ 50 K/W). | Limited to lower-energy transients; less suitable for sustained high-temp operation due to larger thermal resistance. | Select when cost sensitivity outweighs peak power and thermal performance requirements. |
| SMCJ12A | Higher PPPM (1500 W), larger DO-214AB package (7.11 mm × 6.22 mm), VCL = 19.9 V at 75.4 A. | Better for extreme surge events but occupies >3× PCB area; not optimized for 1 mm height constraint. | Choose when surge energy exceeds 600 W and board space permits larger footprint. |
Compared with SMAJ12A, PTVS12VP1UTP,115 offers 50% higher surge power handling and superior thermal management in half the height; versus SMCJ12A, it trades absolute peak current capacity for compactness and high-temperature reliability in space-limited designs.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The PTVS12VP1UTP,115 supports continuous operation at ambient temperatures up to +185 °C, validated per IEC 60134 limiting values. This rating assumes proper PCB thermal design - specifically, use of ≥1 cm² cathode-side copper pour to achieve Rth(j-sp) = 12 K/W and maintain junction temperature below 185 °C under worst-case power dissipation.
Does the device retain its 600 W rating at elevated temperatures?
No - rated peak pulse power decreases with rising junction temperature. At Tj = 150 °C, PPPM drops to approximately 400 W (67% of 25 °C rating), per Figure 2 in the datasheet. Designers must apply derating curves when sizing for sustained high-temperature environments or repetitive surge conditions.
Is the marking "CG" on the device body sufficient to confirm it is PTVS12VP1UTP?
Yes - per Table 4 of the datasheet, "CG" is the official marking code for PTVS12VP1UTP. The bar adjacent to pin 1 indicates the cathode, consistent with SOD128 pinning. No other variant in the series shares this marking, enabling unambiguous visual identification on assembled PCBs.
Can this TVS be used in bidirectional protection configurations?
No - PTVS12VP1UTP,115 is strictly unidirectional. It conducts only during reverse-bias overvoltage events. For bidirectional protection (e.g., AC lines or data lines with polarity reversal), two devices in series opposition or a dedicated bidirectional TVS such as PTVS12VU1UTP would be required.
