Product details
Overview
PTVS14VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 14 V nominal systems. It features VRWM = 14 V, VBR = 15.6–17.2 V (min/max), VCL = 23.2 V at IPPM = 25.9 A (10/1000 µs), IRM ≤ 0.001 µA, and AEC-Q101 qualification - deployed in engine control units and infotainment power rails.
For engineers reviewing the PTVS14VP1UP-QX datasheet, PTVS14VP1UP-QX pinout, PTVS14VP1UP-QX application, or PTVS14VP1UP-QX equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, peak pulse current handling under load dump transients, thermal resistance to PCB copper area, and AEC-Q101 compliance for automotive ECU designs.
Technical Context
This unidirectional TVS diode operates as a shunt protector: under normal bias (VR ≤ 14 V), it presents <0.001 µA leakage; when transient voltage exceeds VBR (15.6–17.2 V), it avalanches into low-impedance conduction to clamp downstream circuitry at ≤23.2 V. Its 1 mm profile and SOD128 footprint support high-density automotive PCB layouts.
Rated per IEC 61643-321 (10/1000 µs waveform), it delivers 600 W peak pulse power with junction temperature derating down to ~40% at 125 °C (Fig. 2). Thermal resistance Rth(j-sp) = 12 K/W enables effective heat transfer via cathode solder point - critical for sustained surge events in 12 V vehicle electrical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14 V - maximum continuous reverse operating voltage before leakage rises; matches nominal 12 V automotive rail with safety margin. |
| VBR (min/max) | 15.6 V / 17.2 V - breakdown threshold range at 1 mA; ensures reliable turn-on before IC damage thresholds. |
| VCL @ IPPM | 23.2 V - clamped voltage at 25.9 A peak pulse; must stay below absolute max rating of protected MCU or PMIC. |
| PPPM | 600 W - peak pulse power handling (10/1000 µs); supports ISO 7637-2 Pulse 5a load dump surges. |
| IRM | ≤0.001 µA - ultra-low reverse leakage at VRWM; prevents battery drain in always-on vehicle modules. |
| AEC-Q101 | Qualified - validated for automotive discrete semiconductor stress tests (HTGB, HTRB, TCT, etc.); required for ECU front-end protection. |
| Rth(j-sp) | 12 K/W - junction-to-solder-point thermal resistance; enables efficient heat dissipation through cathode pad to PCB copper. |
Pinout & Package
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 reflow soldering and space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side with bar; connects to protected circuit's positive rail (anode grounded); defines polarity for unidirectional clamping. |
| 2 (A) | Anode | Connected to ground reference; completes shunt path during overvoltage event; requires low-inductance ground plane routing. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles ISO 7637-2 Pulse 5a load dump transients (up to 100 V, 100 ms) without failure when properly mounted. |
| 1 mm package height | Enables placement under connectors or near ECU housings where vertical clearance is limited to ≤1.2 mm. |
| AEC-Q101 qualification | Validated for automotive temperature cycling (-40 °C to +125 °C), humidity, and mechanical shock - no additional qualification needed. |
| 0.001 µA reverse leakage | Minimizes standby current draw in always-on domains (e.g., CAN wake-up circuits), extending battery life in parked vehicles. |
| Low Rth(j-sp) = 12 K/W | Allows >80% of surge energy to dissipate via cathode pad into PCB copper, reducing localized heating during repeated transients. |
Applications
| Engine Control Unit (ECU) Power Input | Infotainment System DC-DC Input |
|---|---|
Use Scenario: Protects 12 V input stage of gasoline/diesel ECU against load dump (ISO 7637-2 Pulse 5a) and jump-start surges. IC Role / Device Role / Timing Role: Shunt clamping device placed directly at connector entry point, before main fuse and input filter capacitor. Use Value: Clamps transients to ≤23.2 V, preserving integrity of downstream 3.3 V/5 V regulators and microcontroller I/O pins rated to 28 V abs max. |
Use Scenario: Safeguards 12 V input to buck converter supplying 5 V/3.3 V to display processor and audio SoC in head unit. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of EMI filter and input capacitor; responds within nanoseconds. Use Value: Limits voltage overshoot during ignition switching noise, preventing brownout resets and flash memory corruption in real-time OS. |
| Body Control Module (BCM) LIN Bus Power | ADAS Camera Module Power Rail |
Use Scenario: Secures 12 V supply feeding LIN transceiver and relay drivers in door module or lighting controller. IC Role / Device Role / Timing Role: Unidirectional TVS tied between LIN power line and chassis ground; blocks positive-going spikes only. Use Value: Maintains <0.001 µA leakage to avoid disrupting LIN bus sleep current (<100 µA), while clamping ESD and inductive kickback. |
Use Scenario: Shields 12 V input to camera ECU powering image sensor and ISP, exposed to vibration-induced cable coupling. IC Role / Device Role / Timing Role: Mounted adjacent to power connector on compact 2-layer flex-rigid PCB; cathode pad thermally anchored to inner ground plane. Use Value: Withstands 30 kV contact ESD (IEC 61000-4-2) and 100 A non-repetitive surge (IFSM), ensuring uninterrupted video stream during vehicle motion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A-Q | Lower PPPM (400 W), higher VCL (25.5 V), same SOD-123 package but not AEC-Q101 qualified. | Limited to non-safety-critical industrial power supplies; insufficient for automotive load dump compliance. | Select only for cost-sensitive non-automotive designs where 600 W margin and AEC-Q101 are not required. |
| TPSMD14A | Same VRWM (14 V), but VCL = 24.4 V at 24.6 A, Rth(j-a) = 50 K/W (vs. 60 K/W for PTVS14VP1UP-QX), no AEC-Q101 documentation. | Higher clamping voltage reduces system margin; thermal performance inferior in confined PCB layouts. | Use only if legacy design reuse mandates SMA package; verify thermal derating and automotive qualification separately. |
Compared with SMAJ14A-Q and TPSMD14A, PTVS14VP1UP-QX provides superior surge robustness (600 W), lower clamping (23.2 V), certified automotive reliability, and optimized thermal path - making it the preferred choice for new ECU and ADAS power protection designs.

FAQ
What is the maximum clamping voltage of PTVS14VP1UP-QX under standard test conditions?
The maximum clamping voltage (VCL) is 23.2 V at a peak pulse current (IPPM) of 25.9 A, measured using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Does PTVS14VP1UP-QX support bidirectional transient suppression?
No - PTVS14VP1UP-QX is a unidirectional TVS diode, configured to clamp only positive-going transients relative to ground. Its anode is grounded and cathode connects to the protected line. For bidirectional protection (e.g., data lines), a separate symmetric TVS or dual-diode configuration is required.
How does the SOD128 package affect PCB layout and thermal performance?
The SOD128 (CFP5) package features a low 1.0 mm height and cathode tab optimized for direct thermal coupling to PCB copper. Its Rth(j-sp) = 12 K/W requires a minimum 1 cm² cathode pad area on inner ground layers to maintain junction temperature below 150 °C during repeated 600 W pulses - layout guidelines are provided in Figure 7 of the datasheet.
Is PTVS14VP1UP-QX compatible with lead-free reflow soldering processes?
Yes - the device is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), with peak temperatures up to 260 °C. The CFP5 package uses matte tin-plated leads and meets IPC/JEDEC standards for wetting balance and intermetallic formation; recommended solder paste volume and stencil aperture are specified in Figure 7.
