Product details
Overview
PTVS3V3P1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features 3.3 V reverse standoff voltage (VRWM), 5.2–6.0 V breakdown voltage (VBR) at 10 mA, 8.0 V clamping voltage (VCL) at 75 A peak pulse current, and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS3V3P1UTP-QX datasheet, PTVS3V3P1UTP-QX pinout, PTVS3V3P1UTP-QX application, or PTVS3V3P1UTP-QX equivalent, this device is selected for robust ESD/EMI surge suppression in 12 V automotive subsystems, battery management inputs, and high-reliability industrial DC power interfaces where thermal stability and AEC-Q101 compliance are mandatory.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-anode polarity, triggered when reverse voltage exceeds VRWM = 3.3 V. Its IEC 61643-321 compliant 10/1000 µs waveform response delivers 75 A peak pulse current (IPPM) while limiting clamped voltage to 8.0 V - critical for protecting downstream 3.3 V logic and CAN transceivers.
Thermal design is enabled by Rth(j-sp) = 12 K/W to solder point and operation up to Tj = 185 °C, supported by AEC-Q101 qualification and 30 kV IEC 61000-4-2 ESD rating. The SOD128 footprint ensures minimal PCB area while maintaining 1 mm profile for space-constrained modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W per IEC 61643-321 (10/1000 µs); sustains single high-energy surges without failure |
| Reverse Standoff Voltage | VRWM = 3.3 V; defines maximum continuous operating voltage before clamping initiates |
| Clamping Voltage | VCL = 8.0 V at IPPM = 75 A; limits voltage seen by protected ICs during surge events |
| Breakdown Voltage | VBR = 5.2–6.0 V at IR = 10 mA; ensures reliable turn-on margin above VRWM |
| Junction Temperature | Tj ≤ 185 °C; enables deployment in under-hood automotive environments and industrial enclosures |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2); protects against human-body and system-level electrostatic events |
| Package | SOD128 (CFP5); 3.8 × 2.6 × 1.0 mm surface-mount outline with cathode marking bar |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 4 mm pitch, 3.8 mm × 2.6 mm × 1.0 mm body height. Cathode marked by molded bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit's positive rail; absorbs surge current into ground path via anode |
| 2 | Anode (A) | Connected to system ground; completes clamping path during overvoltage transients |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including engine control units, body electronics, and ADAS power supplies |
| High-temperature operation | Rated for continuous operation at Tamb = −55 °C to +185 °C ambient, supporting under-hood placement |
| Low-profile SMD package | 1.0 mm max height enables stacking in compact ECUs and battery management systems |
| Low leakage current | IRM ≤ 0.001 µA at VRWM; minimizes standby power loss in always-on vehicle networks |
| Stable clamping performance | VCL drift < ±5 % across −40 °C to +150 °C; ensures consistent protection across thermal cycles |
Applications
| Automotive Power Rail Protection | Industrial 24 V DC Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A-Q | Lower PPPM = 400 W; VRWM = 3.3 V; VCL = 7.5 V at 53.3 A; SMC package (higher profile, 2.3 mm) | Not rated for 185 °C operation; qualified to AEC-Q101 but with lower thermal margin | Select when cost sensitivity outweighs high-temp requirement and board height allows SMC footprint |
| TPSMF3.3A | PPPM = 600 W; VRWM = 3.3 V; VCL = 9.2 V at 65.2 A; SOD-123FL package (1.3 mm height) | Lacks AEC-Q101 qualification; rated only to Tj = 150 °C; higher clamping voltage reduces protection margin | Use in non-automotive industrial designs where 185 °C operation is unnecessary and 9.2 V clamping is acceptable |
Compared with SMAJ3.3A-Q and TPSMF3.3A, PTVS3V3P1UTP-QX provides superior thermal endurance (185 °C vs. ≤150 °C), lower profile (1.0 mm vs. ≥1.3 mm), and tighter clamping (8.0 V vs. ≥7.5 V), making it the only option qualified for under-hood automotive power rail protection with minimal PCB real estate.

FAQ
What is the maximum clamping voltage of PTVS3V3P1UTP-QX at its rated peak pulse current?
The clamping voltage (VCL) is 8.0 V at a peak pulse current (IPPM) of 75 A, measured under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures safe voltage levels for 3.3 V logic circuits during surge events.
Is PTVS3V3P1UTP-QX suitable for bidirectional transient protection?
No - PTVS3V3P1UTP-QX is a unidirectional TVS diode with cathode-anode polarity. It conducts only during reverse-biased overvoltage events. For bidirectional protection (e.g., data lines), a symmetric device such as PTVS3V3S1UTP-QX would be required.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C Tj rating allows operation in high-ambient zones without derating, but thermal performance depends on solder pad design. Use the recommended reflow footprint (Fig. 7) with 1 cm² cathode copper pour to achieve Rth(j-sp) = 12 K/W and sustain full 600 W pulse capability.
Does PTVS3V3P1UTP-QX require external series impedance for optimal protection?
No external resistor is required for basic clamping function, but a small series inductor or ferrite bead (e.g., 100 nH) between the TVS and protected IC improves high-frequency surge filtering. Layout best practice places the TVS within 5 mm of the connector entry point to minimize inductance in the surge path.
