Product details
Overview
PTVS7V5P1UTP-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 = 7.5 V, VBR(min) = 8.33 V at 1 mA, VCL = 12.9 V at IPPM = 46.5 A (10/1000 µs), Tj(max) = 185 °C, and AEC-Q101 qualified.
For engineers reviewing the PTVS7V5P1UTP-QX datasheet, PTVS7V5P1UTP-QX pinout, PTVS7V5P1UTP-QX application, or PTVS7V5P1UTP-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) - critical for 12 V battery line protection and engine control unit (ECU) interface hardening.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, triggering at breakdown voltage (VBR = 8.33–9.21 V) to shunt surge current away from downstream circuitry. Its unidirectional architecture provides low clamping voltage (VCL = 12.9 V) under 46.5 A peak pulse current, with minimal leakage (IRM ≤ 0.2 µA at VRWM).
Thermal design is enabled by junction-to-solder-point thermal resistance of 12 K/W and rated operation up to 185 °C junction temperature. It complies with IEC 61643-321 (10/1000 µs waveform) and achieves ±30 kV ESD immunity per IEC 61000-4-2, validated under AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.5 V - Maximum continuous reverse operating voltage before clamping begins; sets threshold for 12 V automotive system protection. |
| VBR (min) | 8.33 V at 1 mA - Guaranteed minimum breakdown voltage ensures reliable turn-on during transients without premature conduction. |
| VCL | 12.9 V at IPPM = 46.5 A - Clamped voltage level protects downstream ICs (e.g., CAN transceivers, microcontrollers) from overvoltage damage. |
| PPPM | 600 W - Peak pulse power rating per IEC 61643-321 (10/1000 µs), defining maximum surge energy absorption capability. |
| IRM | ≤ 0.2 µA at VRWM - Ultra-low reverse leakage preserves system efficiency and prevents false triggering in low-power sleep modes. |
| Tj(max) | 185 °C - Enables placement near hot components (e.g., power MOSFETs, ignition drivers) without derating concerns. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air) - Eliminates need for additional ESD protection on board-level interfaces. |
Pinout & Package
PTVS7V5P1UTP-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 thermal dissipation via cathode pad.
| 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-impedance path to earth during transient events; requires low-inductance PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD stress - eliminates requalification effort for Tier 1 suppliers. |
| 185 °C junction rating | Enables direct placement on high-temperature PCB zones (e.g., near engine control modules) without thermal derating penalties. |
| 1 mm package height | Reduces board profile for space-constrained modules (e.g., smart sensors, junction boxes) while maintaining 600 W surge capability. |
| Low VCL / VBR ratio | 12.9 V / 8.33 V ≈ 1.55 - Tight clamping margin ensures robust protection of 5 V and 3.3 V logic interfaces powered from protected 12 V rails. |
| 0.2 µA IRM at VRWM | Minimizes standby current draw in always-on vehicle networks (e.g., LIN, CAN FD partial networking), extending battery life. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-Q | Lower PPPM (400 W), higher VCL (13.4 V), same VRWM (7.5 V), SMA package (higher Rth(j-a) = 50 K/W) | Limited to ambient-temp industrial use; not AEC-Q101 qualified; unsuitable for under-hood deployment | Select only if cost sensitivity outweighs thermal and automotive compliance requirements. |
| TPSMD7.5A | Same VRWM (7.5 V), lower VBR (min 7.1 V), higher VCL (14.4 V), DFN1006 package (Rth(j-sp) = 25 K/W) | Higher clamping voltage risks damage to 5 V logic; smaller footprint reduces thermal mass for repeated surges | Prefer only for compact consumer electronics where 185 °C operation and 600 W rating are unnecessary. |
Compared with SMAJ7.5A-Q and TPSMD7.5A, PTVS7V5P1UTP-QX delivers superior thermal resilience (185 °C vs. 150 °C), lower clamping voltage (12.9 V vs. ≥13.4 V), and automotive qualification - making it the sole choice for under-hood ECU, BCM, and ADAS power protection where reliability and surge margin are non-negotiable.

FAQ
What is the maximum clamping voltage of PTVS7V5P1UTP-QX under standard test conditions?
The clamping voltage (VCL) is 12.9 V measured at a peak pulse current (IPPM) of 46.5 A using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to 185 °C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Does PTVS7V5P1UTP-QX require orientation-specific PCB layout?
Yes - the cathode (pin 1, marked with a bar) must be connected to the line being protected (e.g., battery rail), and the anode (pin 2) to ground. Incorrect orientation prevents clamping action and leaves downstream circuitry fully exposed to transients. The SOD128 footprint must follow Nexperia's recommended reflow solder land pattern (2.5 mm × 3.4 mm cathode pad) for optimal thermal performance.
How does PTVS7V5P1UTP-QX perform at elevated junction temperatures?
Its rated peak pulse power (PPPM) decreases linearly above 25 °C, retaining 80% of 600 W (480 W) at 125 °C and 50% (300 W) at 185 °C, as shown in Figure 2 of the datasheet. This predictable derating enables accurate surge margin calculation in high-temperature environments like engine compartments without requiring external thermal monitoring.
Is PTVS7V5P1UTP-QX compatible with lead-free reflow processes?
Yes - it is qualified for standard lead-free reflow profiles (JEDEC J-STD-020, peak temperature 260 °C, 20–40 s above 217 °C). The CFP5 (SOD128) package uses matte tin-plated leads and meets MSL-1 classification, eliminating moisture sensitivity concerns and enabling direct placement into high-volume SMT lines without baking.
