Product details
Overview
PTVS30VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection in automotive power rails. It features VRWM = 30 V, VBR(min) = 33.3 V, clamping voltage VCL = 48.4 V at IPPM = 12.4 A (10/1000 µs), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS30VP1UTP-QX datasheet, PTVS30VP1UTP-QX pinout, PTVS30VP1UTP-QX application, or PTVS30VP1UTP-QX equivalent, this device is selected for robust ESD and surge immunity in 12 V/24 V automotive subsystems, battery management inputs, and industrial DC power interfaces where thermal stability and AEC-Q101 compliance are mandatory.
Technical Context
This unidirectional TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its 30 V standoff threshold. Its silicon junction delivers precise breakdown at 33.3–36.8 V with <0.001 µA IRM at VRWM, enabling low-leakage protection of sensitive downstream circuitry.
The device sustains 600 W peak pulse power per IEC 61643-321 (10/1000 µs), with thermal resistance Rth(j-sp) = 12 K/W to solder point and full qualification to AEC-Q101 - confirming reliability under thermal cycling, humidity, and mechanical stress typical of engine bay and powertrain environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V automotive systems. |
| VBR (min) | 33.3 V - guaranteed minimum breakdown voltage at 1 mA; ensures predictable turn-on during transients without premature conduction. |
| VCL @ IPPM | 48.4 V at 12.4 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress to safe levels below 50 V. |
| PPPM | 600 W - peak pulse power handling per IEC 61643-321; supports high-energy load dump and ISO 7637-2 Pulse 5a events. |
| Tj max | 185 °C - maximum junction temperature; enables operation in under-hood locations without derating at ambient up to 150 °C. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air); provides system-level ESD immunity without additional external protection layers. |
| AEC-Q101 | Qualified - validated for automotive use including HTOL, TC, UHAST, and bond wire integrity testing per AEC standard. |
Pinout & Package
PTVS30VP1UTP-QX uses the CFP5 (SOD128) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for reflow and wave soldering. The cathode is marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., battery rail); carries surge current to ground during clamping event. |
| 2 (A) | Anode | Connected to system ground; completes conduction path during transient overvoltage conditions. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates thermal derating in engine control units and ADAS modules. |
| Low-profile SMD package | 1.0 mm height - enables placement in space-constrained PCB layouts near connectors or power entry points. |
| Automotive qualification | AEC-Q101 qualified - meets stress test requirements for discrete semiconductors in safety-critical vehicle systems. |
| Low leakage current | IRM ≤ 0.001 µA at VRWM - prevents parasitic drain in always-on battery circuits and extends standby life. |
| Stable clamping performance | VCL variation < ±5 % over Tj = −55 °C to +150 °C - ensures consistent protection across full automotive temperature range. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-Q | Lower PPPM (400 W), higher VCL (48.9 V), same VRWM (30 V), SMA package (2.5 mm height) | Limited to lower-energy transients; less suitable for load dump in 12 V systems | Select when board height allows SMA and surge energy is constrained to <400 W |
| TPSMF30A | Same VRWM (30 V), lower VCL (45.7 V), higher IPPM (13.1 A), but only rated to 175 °C junction | Better clamping performance but reduced high-temperature margin for under-hood use | Prefer for non-engine-bay applications requiring tighter voltage limiting at moderate temperatures |
Compared with PTVS30VP1UTP-QX, SMAJ30A-Q trades peak power and thermal capability for cost and footprint familiarity, while TPSMF30A improves clamping but sacrifices 10 °C of junction headroom critical for sustained high-temp reliability.

FAQ
What is the maximum clamping voltage of PTVS30VP1UTP-QX under standard test conditions?
The clamping voltage VCL is 48.4 V at a peak pulse current IPPM of 12.4 A, measured using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and represents the maximum voltage imposed on protected circuitry during a worst-case surge event.
Is PTVS30VP1UTP-QX suitable for bidirectional transient protection?
No - PTVS30VP1UTP-QX is a unidirectional TVS diode, intended for DC circuits with defined polarity such as automotive battery rails. It conducts only when reverse-biased beyond VRWM. For AC or bidirectional signal lines, a dedicated bidirectional variant like PTVS30VB1UTP-QX must be used.
How does the SOD128 package affect thermal performance in PCB layout?
The SOD128 (CFP5) package features a low thermal resistance of 12 K/W from junction to solder point (Rth(j-sp)), enabled by its flat leads and direct copper contact. To achieve this, the cathode pad must be implemented as a ≥1 cm² thermal land per Nexperia's recommended footprint, minimizing thermal impedance to the PCB plane.
Does PTVS30VP1UTP-QX require external series impedance for optimal protection?
Yes - like all TVS diodes, it must be paired with appropriate series impedance (e.g., ferrite bead or resistor) upstream to limit peak current into the device and prevent thermal runaway during sustained overvoltage. The 600 W rating assumes proper current limiting per IEC 61643-321 waveform definition and PCB trace inductance.
