Product details
Overview
PTVS28VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at VRWM = 28 V, VBR(min) = 31.1 V, VCL(max) = 45.4 V, and IPPM = 13.2 A under 10/1000 μs waveform. It delivers low-profile (1 mm height), AEC-Q101-qualified surge suppression in power supply rails and ECUs.
For engineers reviewing the PTVS28VP1UP-QX datasheet, PTVS28VP1UP-QX pinout, PTVS28VP1UP-QX application, or PTVS28VP1UP-QX equivalent, key selection criteria include clamping voltage at rated peak current, reverse leakage at 28 V standoff, thermal resistance to solder point (12 K/W), and compatibility with reflow/wave soldering footprints per SOD128 layout.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when transient voltage exceeds its 28 V reverse standoff threshold. Its breakdown occurs at minimum 31.1 V (IR = 1 mA), with clamping limited to 45.4 V at 13.2 A peak pulse current - ensuring protected ICs see sub-46 V stress during IEC 61643-321-compliant surges.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to cathode solder point and robust ESD ratings: ±30 kV (IEC 61000-4-2 contact), ±8 kV HBM. The device sustains 100 A non-repetitive forward surge (tp = 8.3 ms) and operates from −55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 28 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin |
| VBR (min) | 31.1 V at IR = 1 mA - guaranteed avalanche initiation threshold; ensures predictable turn-on timing |
| VCL (max) | 45.4 V at IPPM = 13.2 A - worst-case clamped voltage seen by downstream circuitry during surge |
| PPPM | 600 W - peak pulse power handling per IEC 61643-321 (10/1000 μs); determines surge energy absorption capacity |
| IRM | 0.001 µA at VRWM - ultra-low reverse leakage; minimizes standby power loss in battery-critical systems |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to cathode solder point; enables effective PCB heat sinking |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - supports robust system-level ESD immunity without external shielding |
Pinout & Package
PTVS28VP1UP-QX 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 low-profile PCBs. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line's positive rail; conducts surge current to ground when reverse-biased beyond VBR |
| 2 (A) | Anode | Connected to system ground; completes conduction path during transient clamping event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood and ECU applications with full stress test compliance |
| 1 mm package height | Enables use in space-constrained modules (e.g., ADAS camera housings, motor control inverters) |
| Low Rth(j-sp) = 12 K/W | Supports high-reliability operation under repeated surge events via efficient cathode-side heat dissipation |
| 0.001 µA IRM at VRWM | Reduces quiescent current drain in always-on vehicle networks (e.g., CAN FD wake-up circuits) |
| IEC 61643-321 compliance | Guarantees standardized 10/1000 μs surge response for interoperable system-level EMC validation |
Applications
| Automotive Power Distribution | Industrial PLC I/O Protection |
|---|---|
Use Scenario: 12 V battery rail protection in engine control units against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery input and DC-DC converter input stage. Use Value: Limits transients to ≤45.4 V, preventing damage to 40 V-rated buck controllers and enabling single-stage protection architecture. |

IC Role / Device Role / Timing Role: Primary surge suppressor on field-side signal line before optocoupler or Schmitt trigger input. Use Value: Clamps 1 kV/50 Ω transients within 1 ns, preserving signal integrity and eliminating need for RC snubbers. |
| Automotive Body Control Module | Power Supply Input Stage |
Use Scenario: Protection of LIN bus transceivers and microcontroller GPIOs against ESD and cable discharge events. IC Role / Device Role / Timing Role: Localized TVS at connector entry point, shunting fast transients directly to chassis ground.

Use Scenario: Front-end protection of AC-DC or DC-DC power supplies in medical and test equipment. IC Role / Device Role / Timing Role: First-line defense against lightning-induced surges entering via mains or PoE interfaces. Use Value: Absorbs 600 W peak power without degradation, maintaining regulation stability across 100,000+ surge cycles. |
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-Q | Lower PPPM (400 W), higher VCL (49.1 V at 8.2 A), SMA package (2.5 mm height) | Limited to lower-energy surges; less suitable for ISO 7637-2 Pulse 5a load dump | Select when cost sensitivity outweighs peak surge margin and board height allows SMA footprint |
| TPSMD28A | Same VRWM/VCL specs but non-AEC-Q101; Rth(j-a) = 200 K/W vs. 60 K/W (SOD128) | Not qualified for automotive; requires larger copper pour for thermal management | Prefer for industrial-only designs where AEC compliance is unnecessary and thermal budget permits |
Compared with SMAJ28A-Q and TPSMD28A, PTVS28VP1UP-QX offers superior surge energy handling (600 W), lower clamping (45.4 V), AEC-Q101 assurance, and optimized thermal performance in a 1 mm profile - making it the preferred choice for automotive power rail protection where reliability and space constraints coexist.

FAQ
What is the maximum clamping voltage of PTVS28VP1UP-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 45.4 V at IPPM = 13.2 A under the IEC 61643-321 10/1000 μs waveform. This value is measured with the device mounted per standard SOD128 footprint and represents the worst-case voltage imposed on protected circuitry during a full-rated surge event.
Does PTVS28VP1UP-QX meet automotive qualification standards?
Yes - it is fully qualified to AEC-Q101 for stress testing of discrete semiconductors, including temperature cycling, humidity bias, and ESD. Its qualification covers operation from −55 °C to +150 °C junction temperature and supports use in engine control, body electronics, and ADAS modules.
How does the SOD128 package affect thermal performance compared to SMA or SMB?
The SOD128 (CFP5) package achieves Rth(j-sp) = 12 K/W to the cathode solder point - significantly lower than SMA (≈40 K/W) or SMB (≈25 K/W) - due to its wide, flat cathode tab and optimized thermal pad layout. This enables higher surge repetition rates without thermal runaway in compact layouts.
Can PTVS28VP1UP-QX be used in bidirectional protection configurations?
No - it is a unidirectional TVS diode intended for DC rail protection only. For bidirectional AC or data-line protection, a dedicated bidirectional variant (e.g., PTVS28VU1UP-QX) or back-to-back unidirectional pair would be required; using this part in reverse-bias beyond VRWM risks permanent damage.
