Product details
Overview
PTVS28VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection with VRWM = 28 V, VBR(min) = 31.1 V, VCL = 45.4 V at IPPM = 13.2 A, and junction temperature rating up to 185 °C. It serves as primary clamping protection on DC power rails in industrial and harsh-environment power management systems.
For engineers reviewing the PTVS28VP1UTP,115 datasheet, PTVS28VP1UTP,115 pinout, PTVS28VP1UTP,115 application, or PTVS28VP1UTP,115 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, thermal resistance to PCB (Rth(j-sp) = 12 K/W), peak pulse current handling under 10/1000 µs waveform, and compatibility with reflow soldering footprints for SOD128.
Technical Context
This TVS diode operates in avalanche breakdown mode during transients, providing low-impedance shunt path from anode to cathode when reverse voltage exceeds VBR. Its unidirectional architecture blocks only negative-going surges while allowing normal forward conduction in specific circuit configurations.
Rated for 600 W peak pulse power per IEC 61643-321 (10/1000 µs), it maintains stable clamping performance across −55 °C to +185 °C ambient, with IRM ≤ 0.001 µA at VRWM and temperature coefficient SZ = 30.6 mV/K - enabling predictable voltage shift under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 28 V - maximum continuous reverse operating voltage before leakage rises significantly; sets upper limit for protected rail voltage. |
| VBR (min) | 31.1 V - guaranteed minimum breakdown voltage at 1 mA; ensures reliable triggering above normal operating voltage. |
| VCL | 45.4 V - clamped voltage at 13.2 A peak pulse current; defines worst-case overvoltage seen by downstream components. |
| PPPM | 600 W - peak pulse power handling capability under standardized 10/1000 µs surge; determines survivability against common lightning/EFT events. |
| Tj(max) | 185 °C - maximum junction temperature; enables use in under-hood automotive modules or high-ambient industrial enclosures without derating. |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to solder point; confirms effective heat transfer into PCB copper, critical for repeated surge duty cycles. |
| IRM | 0.001 µA - reverse leakage at VRWM; negligible loading on 28 V supply rails, preserving efficiency in always-on systems. |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 28 V rail); surge current flows from anode to cathode during clamping. |
| 2 (A) | Anode | Typically tied to ground or lower-potential reference; forms low-impedance path to sink transient energy. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation up to Tj = 185 °C - eliminates need for thermal derating in sealed enclosures or near heat sources. |
| Low-profile packaging | 1.0 mm max height - enables use in space-constrained modules such as motor control inverters or battery management units. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard - supports deployment in non-safety-critical automotive subsystems (e.g., body electronics, HVAC). |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >8 kV HBM - provides system-level ESD immunity without additional front-end protection. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ28A | Same VRWM (28 V), but lower PPPM = 400 W and higher VCL = 48.4 V at IPPM = 8.3 A; Rth(j-a) = 60 K/W vs. 12 K/W to solder point. | Not rated for Tj > 150 °C; unsuitable for sustained high-ambient deployments like under-hood modules. | Select when cost sensitivity outweighs thermal performance and peak power demands are below 400 W. |
| Vishay SMF28A | Identical VRWM and VBR range, but lower PPPM = 200 W and VCL = 48.4 V at IPPM = 4.1 A; no AEC-Q101 qualification stated. | Limited to commercial-temperature applications; lacks documented high-temp stability data beyond 150 °C. | Choose only for non-automotive, low-energy transient environments where footprint compatibility is prioritized over surge endurance. |
Compared with Littelfuse SMAJ28A and Vishay SMF28A, PTVS28VP1UTP,115 delivers 50% higher peak power handling, 7% lower clamping voltage, direct thermal coupling to PCB (12 K/W), and verified operation up to 185 °C - making it the sole option among the three qualified for extended high-temperature reliability in industrial and automotive contexts.

FAQ
What is the maximum clamping voltage of PTVS28VP1UTP,115 under specified test conditions?
The maximum clamping voltage (VCL) is 45.4 V, measured at a peak pulse current (IPPM) of 13.2 A using the standardized 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS28VP1UTP,115 suitable for automotive applications despite revision history notes about qualification status?
Yes - the revision history confirms PTVS28VP1UTP,115 remains AEC-Q101 qualified (Section 11, Test Information). The note refers to *other* part numbers removed from automotive qualification; this specific variant retains full automotive qualification and is explicitly listed in the v.2 revision history as unchanged.
How does the thermal resistance Rth(j-sp) = 12 K/W impact PCB layout requirements?
Rth(j-sp) = 12 K/W requires direct thermal connection of the cathode pad (Pin 1) to a minimum 1 cm² copper pour on FR4, as specified in Table 6. Layout must avoid thermal relief spokes and use solid copper fill under the device to achieve rated 185 °C junction operation; insufficient copper area will cause premature thermal shutdown during repetitive surges.
Can PTVS28VP1UTP,115 be used in bidirectional protection configurations?
No - it is strictly unidirectional. Its internal structure allows conduction only from anode to cathode during reverse overvoltage. For bidirectional protection (e.g., AC lines or data lines), a separate symmetric TVS pair or dedicated bidirectional device such as PTVS28VS1UTP is required; mixing unidirectional devices for bidirectional clamping risks failure.
