Product details
Overview
PTVS28VP1UP,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 28 V reverse standoff voltage (VRWM), 32.8 V typical breakdown voltage (VBR), 45.4 V clamping voltage (VCL) at 13.2 A peak pulse current (IPPM), and <0.001 µA reverse leakage at VRWM - enabling robust protection in space-constrained industrial and power management systems.
For engineers reviewing the PTVS28VP1UP,115 datasheet, PTVS28VP1UP,115 pinout, PTVS28VP1UP,115 application, or PTVS28VP1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (Rth(j-sp) = 12 K/W), AEC-Q101 qualification status per revision history, and compatibility with reflow/wave soldering footprints for SOD128.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR (~32.8 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its 600 W peak pulse power rating is defined per IEC 61643-321 (10/1000 µs waveform) at Tj = 25 °C, with derating to ~40% at 125 °C per Fig. 2.
The device uses planar silicon junction technology with cathode-anode polarity marked by a bar on the SOD128 body. Its 1 mm profile and 3.8 × 2.6 mm footprint support high-density PCB layouts, while thermal resistance from junction to solder point (12 K/W) enables effective heat dissipation through the cathode pad during repetitive transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W per IEC 61643-321 (10/1000 µs); defines maximum single-event surge energy handling capability |
| Reverse Standoff Voltage (VRWM) | 28 V; maximum continuous DC voltage before significant leakage - sets operating rail upper limit |
| Breakdown Voltage (VBR) | 32.8 V typical at IR = 1 mA; voltage at which avalanche conduction begins, defining protection threshold onset |
| Clamping Voltage (VCL) | 45.4 V at IPPM = 13.2 A; maximum voltage seen by protected circuit during full-rated surge event |
| Reverse Leakage (IRM) | 0.001 µA at VRWM; negligible standby current draw, critical for low-power battery-backed systems |
| Package | SOD128 (CFP5); 2-terminal surface-mount plastic package, 3.8 × 2.6 × 1.0 mm, cathode-marked |
| Thermal Resistance (Rth(j-sp)) | 12 K/W to solder point; enables efficient heat transfer from junction to PCB copper, supporting repeated surge duty |
Pinout & Package
SOD128 (CFP5) package: ultra-flat 2-terminal surface-mount plastic case with 1 mm height, 4 mm lead pitch, and cathode identified by a molded bar marking on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; avalanche conduction occurs from cathode to anode during overvoltage |
| 2 (A) | Anode | Connected to ground or low-impedance return path; completes shunt path for surge current diversion |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors (per revision history v.3 for PTVS28VP1UP) |
| Low-profile mounting | 1.0 mm max height enables use in height-sensitive applications such as automotive ECUs and portable power modules |
| High ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM ensures resilience against handling and system-level ESD events |
| Optimized thermal path | 12 K/W junction-to-solder-point thermal resistance allows direct heat sinking via cathode pad, improving surge endurance |
| Standardized footprint | Compatible with JEDEC-standard SOD128 reflow and wave soldering land patterns (Fig. 7 & 8), ensuring manufacturability |
Applications
| Industrial Power Supply Protection | DC Motor Drive Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A | DO-214AC package; 400 W PPPM; 45.7 V VCL at 13.1 A; 1.5 mm height | Larger footprint and higher profile limits use in ultra-thin designs; lower peak power reduces margin for severe transients | Choose when DO-214AC board space and legacy footprint compatibility outweigh need for 600 W rating and 1 mm height |
| SMCJ28A | DO-214AB package; 1500 W PPPM; 48.4 V VCL at 31.0 A; 2.6 mm height | Higher clamping voltage increases risk to 3.3 V/5 V logic; larger size conflicts with dense SMT layouts | Prefer for high-energy automotive load-dump scenarios where 1500 W capacity justifies added volume and cost |
Compared with SMAJ28A and SMCJ28A, PTVS28VP1UP,115 delivers optimal balance of 600 W surge capacity, 45.4 V clamping, 1 mm profile, and AEC-Q101 qualification - making it uniquely suited for next-generation industrial and telecom power interfaces where space, reliability, and standardized SOD128 assembly are critical.

FAQ
Is PTVS28VP1UP,115 still AEC-Q101 qualified?
Yes - according to the revision history (v.3, 1 December 2025), PTVS28VP1UP is explicitly listed among the 25 types that retain AEC-Q101 qualification. This status applies to devices manufactured under the current specification and confirms suitability for automotive power rail protection where qualification is required.
What is the recommended PCB footprint for PTVS28VP1UP,115?
The official reflow soldering footprint is defined in Figure 7: two 2.1 × 1.9 mm solder lands spaced 4.4 mm center-to-center, with 3.4 mm occupied area width. For wave soldering, Figure 8 specifies 4.35 × 3.5 mm lands with 5.7 mm spacing. Both footprints align with JEDEC SOD128 standards and optimize thermal transfer to the cathode pad.
How does clamping voltage vary with temperature?
VCL increases with junction temperature - typical data shows ~0.1% per °C rise above 25 °C. At 125 °C, VCL rises to approximately 47.2 V (based on Fig. 2 derating curve and thermal coefficient interpolation). Designers must verify worst-case clamping margin at maximum operating Tj.
Can PTVS28VP1UP,115 be used in bidirectional configurations?
No - it is strictly unidirectional. The internal structure is a single PN junction with cathode/anode polarity. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., PTVS28VU1UP) should be selected instead.
