Product details
Overview
PTVS33VP1UTP-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. Confirmed parameters: VRWM = 33 V, VBR(min) = 36.7 V, VCL = 53.3 V at IPPM = 11.3 A, Tj ≤ 185 °C, and AEC-Q101 qualified.
For engineers reviewing the PTVS33VP1UTP-QX datasheet, PTVS33VP1UTP-QX pinout, PTVS33VP1UTP-QX application, or PTVS33VP1UTP-QX equivalent, this page delivers verified electrical specs, thermal derating behavior, cathode/anode terminal mapping, and automotive-grade ESD robustness (±30 kV contact/air discharge) - all critical for 12 V/24 V vehicle subsystems requiring reliable clamping under thermal stress.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM (33 V), then avalanches sharply at VBR (36.7–40.6 V) to divert surge current away from downstream ICs. Its junction-to-solder-point thermal resistance is 12 K/W, enabling sustained operation at 185 °C junction temperature.
Clamping performance is specified per IEC 61643-321 (10/1000 μs waveform); peak pulse power de-rates linearly above 25 °C, retaining 50% of 600 W capability at ~150 °C. Reverse leakage stays ≤0.1 µA up to 150 °C, ensuring low standby power loss in always-on automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 33 V - Maximum continuous reverse operating voltage before clamping begins; sets threshold for 12 V/24 V rail protection. |
| VBR (min) | 36.7 V - Minimum breakdown voltage at 5 mA; guarantees clamping activation within safe margin above VRWM. |
| VCL @ IPPM | 53.3 V - Clamped voltage at 11.3 A peak pulse current; defines maximum stress imposed on protected circuitry. |
| PPPM | 600 W - Peak pulse power handling (10/1000 μs); supports ISO 7637-2 Pulse 1/2a/5a surge immunity compliance. |
| Tj max | 185 °C - Maximum junction temperature; enables placement near hot engine-control units without derating loss. |
| ESD rating | ±30 kV (IEC 61000-4-2 contact/air); eliminates need for external ESD diodes in infotainment and ADAS sensor interfaces. |
| Rth(j-sp) | 12 K/W - Junction-to-solder-point thermal resistance; allows direct thermal coupling to PCB copper for effective heat dissipation. |
Pinout & Package
Package: CFP5 (SOD128) - surface-mounted plastic package, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated reflow assembly and high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., battery rail); marking bar identifies this terminal; carries full surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; forms low-inductance return path essential for fast transient response (<1 ns turn-on). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including engine bay, transmission control, and ADAS ECUs with zero infant mortality under stress. |
| 185 °C junction rating | Enables direct mounting on high-temperature PCBs (e.g., near DC-DC converters or motor drivers) without thermal derating penalties. |
| 1 mm profile height | Reduces board-level mechanical interference in stacked modules and enables conformal coating compatibility without air gaps. |
| Low IRM ≤ 0.1 µA @ 150 °C | Minimizes quiescent current drain in always-on vehicle networks (e.g., CAN FD wake-up circuits), preserving battery life. |
| 600 W pulse power | Meets ISO 7637-2 Level IV surge requirements for 24 V commercial vehicle systems with single-device simplicity. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Power Rail |
|---|---|

Use Scenario: Protects torque and position sensor signal lines (e.g., SENT, PWM) from coupled transients in EPS motor drive zones. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. 100 pF @ 0 V) placed directly at connector; preserves signal integrity for sub-µs timing-critical feedback. Use Value: Maintains sensor accuracy and fault-free operation across -40 °C to 150 °C ambient, supporting ASIL-C system integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-Q | Lower PPPM (400 W), higher VCL (64.5 V), same VRWM (33 V), SMC package (2.5 mm height) | Limited to under-hood ambient ≤150 °C; unsuitable for direct engine-block mounting | Select when cost sensitivity outweighs thermal margin and board space permits larger footprint. |
| TPSMD33A | Same PPPM (600 W), lower Tj max (175 °C), higher IRM (1 µA @ 150 °C), identical SOD128 footprint | Requires additional thermal design margin in high-heat zones; less suitable for long-life engine bay deployments | Choose only if legacy design reuse mandates identical pinout with relaxed thermal spec. |
Compared with SMAJ33A-Q and TPSMD33A, PTVS33VP1UTP-QX delivers superior thermal resilience (185 °C vs. ≤175 °C), lower clamping voltage (53.3 V vs. ≥64.5 V), and tighter leakage control (0.1 µA vs. ≥1 µA), making it the optimal choice for next-generation automotive power protection where reliability under sustained thermal stress is non-negotiable.

FAQ
What is the maximum clamping voltage for PTVS33VP1UTP-QX under standard test conditions?
The clamping voltage VCL is 53.3 V at a peak pulse current IPPM of 11.3 A, measured using the IEC 61643-321 10/1000 μs waveform. This value ensures protected circuits remain below 55 V during worst-case transients, safeguarding 3.3 V/5 V logic and 12 V analog front-ends.
Does PTVS33VP1UTP-QX support reflow soldering, and what is its recommended footprint?
Yes, it is qualified for lead-free reflow soldering. The recommended footprint follows Nexperia's CFP5 (SOD128) layout: 2.5 mm × 3.4 mm solder lands with 1.9 mm × 2.1 mm solder paste openings per pad, as defined in Figure 7 of the datasheet for optimal thermal transfer and void minimization.
How does the 185 °C junction rating impact real-world automotive placement?
The 185 °C Tj max allows direct placement adjacent to high-power components like DC-DC converters or motor gate drivers without heatsinks or spacing compromises. In practice, this enables compact ECU designs that pass thermal validation at 125 °C ambient + 60 °C self-heating, extending service life beyond 15 years.
Is PTVS33VP1UTP-QX compatible with wave soldering processes?
Yes - Nexperia provides a dedicated wave soldering footprint (Figure 8) with 4.2 mm × 5.7 mm occupied area and 3.5 mm × 3.65 mm solder lands. This layout ensures full wetting of both terminals while minimizing bridging risk, validated for standard SnPb and lead-free wave profiles.
