Product details
Overview
PTVS7V5P1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 7.5 V reverse standoff voltage. It delivers 46.5 A peak pulse current (IPPM), clamps transients to 12.9 V (VCL), and exhibits ≤0.2 µA reverse leakage at VRWM, qualifying per AEC-Q101 for under-hood power rail protection.
For engineers reviewing the PTVS7V5P1UP-QX datasheet, PTVS7V5P1UP-QX pinout, PTVS7V5P1UP-QX application, or PTVS7V5P1UP-QX equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, thermal resistance to PCB (Rth(j-sp) = 12 K/W), 30 kV ESD robustness, and SOD128 footprint compatibility with high-density automotive PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamp, conducting only during negative transients relative to its anode–cathode polarity. Its breakdown voltage (VBR) is 8.33–9.21 V at 1 mA, ensuring reliable turn-on before system damage while maintaining low leakage (<0.2 µA) below 7.5 V.
It conforms to IEC 61643-321 (10/1000 µs waveform) and sustains 600 W peak pulse power at 25 °C, derating to ~40% at 125 °C per Fig. 2. Junction-to-solder-point thermal resistance of 12 K/W enables effective heat dissipation into copper pads on FR4 or ceramic substrates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - Sustains 10/1000 µs surge without failure; defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 7.5 V - Maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected line operating voltage |
| Clamping Voltage (VCL) | 12.9 V at IPPM - Maximum voltage seen by downstream circuit during 46.5 A transient; determines safe margin for 12 V system ICs |
| Breakdown Voltage (VBR) | 8.33–9.21 V at 1 mA - Confirmed turn-on threshold; ensures activation prior to VCL exceeding 12.9 V |
| Peak Pulse Current (IPPM) | 46.5 A - Peak current handled at VCL; directly derived from PPPM / VCL and validates surge handling per ISO 7637-2 |
| Reverse Leakage (IRM) | ≤0.2 µA at VRWM - Negligible standby power loss; avoids battery drain in always-on automotive modules |
| ESD Rating | ±30 kV contact discharge - Exceeds IEC 61000-4-2 Level 4; protects against human-body and cable-discharge events |
Pinout & Package
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 reflow and space-constrained automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side (bar); connects to protected line (e.g., 12 V rail); carries surge current to ground during clamping |
| 2 (A) | Anode | Connects to system ground; completes conduction path during reverse-biased transient events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use up to 150 °C junction temperature and 1000-cycle thermal cycling |
| Low-profile SOD128 package | 1.0 mm max height enables placement beneath connectors or in stacked multi-layer modules without mechanical interference |
| High ESD immunity | 30 kV contact/air discharge rating eliminates need for additional ESD protection stages in CAN/LIN bus interfaces |
| Thermal performance | Rth(j-sp) = 12 K/W allows >50% higher sustained power dissipation than standard SOD-123 when soldered to 1 cm² cathode pad |
| Controlled clamping ratio | VCL/VBR = 1.55 typical ensures predictable voltage limiting without excessive overshoot during fast-rising load-dump events |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS7V5S1UR | Same VRWM and VCL, but SOD-123 package (1.6 mm height) and lower PPPM (400 W) | Limited to non-automotive industrial use due to lack of AEC-Q101 qualification | Select when board height <1.6 mm is critical and surge energy is ≤400 W |
| SMAJ7.5A-Q | Higher VCL (12.5 V), same VRWM, but larger SMA package (2.3 mm height) and no AEC-Q101 certification | Not recommended for automotive ECU designs requiring qualified components | Choose only for cost-sensitive consumer applications where AEC-Q101 is not mandated |
Compared with PTVS7V5S1UR and SMAJ7.5A-Q, the PTVS7V5P1UP-QX uniquely combines AEC-Q101 qualification, 600 W surge capacity, and 1.0 mm profile-enabling compact, high-reliability protection in automotive power domains where both space and qualification are non-negotiable.

FAQ
What is the maximum operating temperature for PTVS7V5P1UP-QX in continuous service?
The device supports continuous operation up to 150 °C junction temperature (Tj), verified per AEC-Q101 stress testing. Ambient temperature range is −55 °C to +150 °C, and thermal resistance to solder point is 12 K/W-enabling reliable performance in under-hood environments when mounted on ≥1 cm² copper pour.
How does PTVS7V5P1UP-QX differ from standard SOD-123 TVS diodes in surge handling?
It delivers 600 W peak pulse power (vs. ≤400 W for most SOD-123 variants) due to optimized SOD128 thermal design and silicon structure. Its Rth(j-sp) of 12 K/W allows ~2.5× higher sustained power dissipation than typical SOD-123 parts, making it suitable for repetitive load-dump events in 12 V automotive systems.
Can PTVS7V5P1UP-QX be used for bidirectional transient protection?
No-it is a unidirectional TVS diode with cathode/anode polarity. For bidirectional protection (e.g., data lines), a symmetric pair or dedicated bidirectional device like PTVS7V5D1UP-QX is required. Using this part in reverse bias beyond VRWM will cause permanent damage.
What PCB layout practices maximize thermal performance of PTVS7V5P1UP-QX?
Maximize copper area connected to the cathode pad (Pin 1), using ≥1 cm² of 2 oz copper with multiple thermal vias to inner/ground layers. Follow Nexperia's SOD128 reflow footprint (Fig. 7): 2.5 mm × 3.4 mm solder land with 1.9 mm × 2.1 mm stencil aperture for optimal solder joint integrity and heat transfer.
