Product details
Overview
PTVS12VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy transient overvoltage protection on DC power rails. It features a 12 V reverse standoff voltage (VRWM), 14.7 V maximum clamping voltage (VCL) at 30.2 A peak pulse current (IPPM), and 0.005 µA reverse leakage at VRWM - optimized for robust surge suppression in industrial and automotive-grade power management circuits.
For engineers reviewing the PTVS12VP1UP,115 datasheet, PTVS12VP1UP,115 pinout, PTVS12VP1UP,115 application, or PTVS12VP1UP,115 equivalent, this device delivers verified IEC 61643-321 (10/1000 µs) compliance, AEC-Q101 qualification, and low-profile surface-mount compatibility - critical for space-constrained 12 V system protection in ECUs, power supplies, and motor control modules.
Technical Context
This unidirectional TVS diode operates as a clamping device: under normal bias it presents high impedance (>10⁹ Ω at 12 V), but triggers avalanche breakdown at ≥13.3 V (min VBR) to shunt transients. Its 1 mm profile and 3.8 mm × 2.6 mm footprint enable dense PCB layouts without compromising thermal performance.
Thermal resistance from junction to solder point is 12 K/W, enabling effective heat dissipation during repetitive surges. The cathode-marked SOD128 package supports reflow and wave soldering per defined footprints, with validated ESD robustness of 30 kV (IEC 61000-4-2 contact discharge).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surges up to 600 W without failure per IEC 61643-321 |
| Reverse Standoff Voltage (VRWM) | 12 V - maximum continuous DC voltage before significant leakage; ensures stable operation in 12 V systems |
| Clamping Voltage (VCL) | 14.7 V max at IPPM = 30.2 A - limits downstream voltage to safe levels during surge events |
| Breakdown Voltage (VBR) | 13.3–14.7 V (min–max) - precise avalanche threshold ensures predictable turn-on behavior |
| Reverse Leakage (IRM) | 0.005 µA at VRWM - negligible standby current, critical for low-power and battery-backed systems |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - protects against human-body model and system-level ESD events |
| Package | SOD128 (CFP5) - 3.8 mm × 2.6 mm × 1.0 mm surface-mount package with cathode marking bar |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package with 2 terminals, 4 mm pitch, and 1 mm maximum height. Cathode identified by molded marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); carries surge current to ground during clamping |
| 2 | Anode (A) | Connected to system ground; completes conduction path when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics |
| Low-profile SMD package | 1 mm height enables use in ultra-thin modules and stacked PCB assemblies |
| High surge current capability | 30.2 A peak pulse current (IPPM) at 10/1000 µs waveform ensures reliable protection against ISO 7637-2 pulses |
| Ultra-low leakage | 0.005 µA at 12 V reduces standby power loss and avoids false triggering in precision sensing rails |
| Controlled clamping ratio | VCL/VRWM = 1.23 - tight voltage margin preserves headroom for downstream ICs rated to 16 V |
Applications
| Automotive Engine Control Unit (ECU) | Industrial 12 V Power Supply |

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 | DO-214AC package; 400 W PPPM; 13.3 V VRWM; 19.9 V VCL at 23.3 A | Higher clamping voltage and lower surge rating; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and compactness requirements |
| SMCJ12A | DO-214AB package; 1500 W PPPM; 12 V VRWM; 19.9 V VCL at 75.4 A | Larger footprint (7.1 mm × 6.2 mm); higher clamping ratio (1.66×); no AEC-Q101 status | Choose for higher-energy surge environments where board space allows and automotive qualification is not required |
Compared with SMAJ12A and SMCJ12A, PTVS12VP1UP,115 offers superior space efficiency (SOD128 vs. DO-214AC/AB), certified automotive qualification, and tighter clamping (14.7 V vs. ≥19.9 V), making it optimal for next-gen compact, safety-critical 12 V systems.

FAQ
What is the maximum clamping voltage of PTVS12VP1UP,115 at its rated peak pulse current?
The maximum clamping voltage (VCL) is 14.7 V at 30.2 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures downstream 16 V-rated ICs remain within safe operating limits during surge events.
Is PTVS12VP1UP,115 qualified for automotive applications?
Yes - PTVS12VP1UP,115 is AEC-Q101 qualified per the revision history (v.3, December 2025), confirming stress-test validation for discrete semiconductors in automotive environments. It is explicitly listed among the 25 products upgraded to standard automotive qualification in the latest datasheet.
How does the SOD128 package affect thermal performance compared to larger TVS packages?
The SOD128 package achieves a junction-to-solder-point thermal resistance (Rth(j-sp)) of 12 K/W, enabled by its cathode tab design and optimized copper pad layout. This outperforms typical DO-214AC packages (Rth(j-sp) ≈ 25–30 K/W), allowing faster heat transfer to the PCB and improved reliability under repetitive surge conditions.
Can PTVS12VP1UP,115 be used in bidirectional configurations?
No - PTVS12VP1UP,115 is a unidirectional TVS diode with anode and cathode terminals. It conducts only when cathode voltage exceeds anode by ≥13.3 V. For bidirectional protection (e.g., data lines), a separate symmetric device such as PTVS12VS1UP would be required.
