Product details
Overview
PTVS15VP1UTP-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 = 15 V, VBR(min) = 16.7 V, VCL = 24.4 V at IPPM = 24.6 A (10/1000 µs), Tj(max) = 185 °C, and AEC-Q101 qualified.
For engineers reviewing the PTVS15VP1UTP-QX datasheet, PTVS15VP1UTP-QX pinout, PTVS15VP1UTP-QX application, or PTVS15VP1UTP-QX equivalent, this page delivers verified electrical specs, thermal behavior at elevated junction temperatures, clamping performance under IEC 61643-321 waveforms, and automotive-grade reliability data - all critical for robust ESD/surge protection design in engine control units and battery management systems.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transients above its reverse standoff voltage (VRWM = 15 V). It exhibits low IRM = 0.001 µA at VRWM and a temperature coefficient SZ = +14.1 mV/K, ensuring stable clamping across -55 °C to +185 °C ambient.
Its 600 W peak pulse power rating follows IEC 61643-321 (10/1000 µs waveform), with clamping voltage VCL = 24.4 V measured at 5 mA test current and rated peak pulse current IPPM = 24.6 A. Thermal resistance Rth(j-sp) = 12 K/W enables effective heat transfer via cathode solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min) | 16.7 V - Minimum breakdown voltage at 10 mA; ensures reliable turn-on during surge events. |
| VCL | 24.4 V - Clamped voltage at IPPM = 24.6 A (10/1000 µs); determines protected circuit's maximum stress level. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321; supports high-energy surge immunity. |
| Tj(max) | 185 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Rth(j-sp) | 12 K/W - Junction-to-solder-point thermal resistance; guides PCB copper pad sizing for thermal management. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air); provides system-level electrostatic discharge immunity without external shielding. |
Pinout & Package
PTVS15VP1UTP-QX uses the CFP5 (SOD128) 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 high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by bar on package; connects to protected line (e.g., 12 V rail) for unidirectional clamping to ground. |
| 2 | Anode (A) | Positive terminal; tied to system ground; completes avalanche conduction path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including engine control, infotainment, and ADAS power domains. |
| 185 °C junction rating | Enables direct placement near high-heat sources (e.g., power converters, motor drivers) without derating. |
| 1 mm package height | Reduces board profile and improves airflow in stacked modules or compact ECUs. |
| Low IRM = 0.001 µA | Minimizes standby leakage in always-on vehicle networks (e.g., CAN, LIN), preserving battery life. |
| 600 W pulse capability | Withstands ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 5a/b (alternator load dump) without failure. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Battery Management System (BMS) |
|---|---|
Use Scenario: Protection of 12 V supply input against load dump transients (ISO 7637-2 Pulse 5a/b) and coupled noise in gasoline/diesel engine compartments. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and local regulator input; clamps within nanoseconds to limit voltage to <24.4 V. Use Value: Prevents damage to downstream LDOs and microcontrollers during alternator field collapse events up to 600 W energy. |
Use Scenario: Safeguarding BMS analog front-end (AFE) and communication ICs from battery terminal transients during jump-start or short-circuit recovery. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main battery feed; positioned upstream of fuse and precharge circuitry. Use Value: Maintains functional safety integrity by limiting fault voltage to ≤24.4 V while surviving repeated 10/1000 µs surges per AEC-Q101 stress testing. |
| ADAS Camera Module Power Rail | Electric Power Steering (EPS) Motor Driver Supply |
Use Scenario: Protecting image sensor and SerDes IC power pins from ESD and switching noise generated by nearby radar or infotainment RF modules. IC Role / Device Role / Timing Role: Local TVS at camera module connector; suppresses fast transients (<1 ns rise time) before they couple into sensitive analog video paths. Use Value: Eliminates visual artifacts and resets caused by ±30 kV ESD events, meeting ISO 10605 compliance without additional filtering. |
Use Scenario: Shielding H-bridge gate drivers and current sense amplifiers from inductive kickback during EPS motor commutation and emergency stop. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional PTVS15VP1UTP-QX clamps positive surges only on 12 V logic supply. Use Value: Ensures uninterrupted torque assist by preventing latch-up or burnout in driver ICs exposed to >100 V spikes during MOSFET turn-off. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-Q | Lower PPPM = 400 W; VRWM = 15 V; VCL = 24.4 V; same SOD-123 package but lower thermal robustness (Tj = 150 °C). | Limited to under-dash non-engine-bay applications; not qualified to AEC-Q101. | Select when cost sensitivity outweighs under-hood thermal requirements and automotive qualification is optional. |
| TPSMD15H | Higher PPPM = 1500 W; VRWM = 15 V; VCL = 25.5 V; DO-214AB package; Tj = 175 °C; AEC-Q101 qualified. | Better suited for high-energy load dump in commercial vehicles; larger footprint requires layout revision. | Choose for heavy-duty truck or bus BMS where ISO 7637-2 Pulse 5b energy exceeds 600 W limits. |
Compared with SMAJ15A-Q and TPSMD15H, PTVS15VP1UTP-QX uniquely balances AEC-Q101 compliance, 185 °C operation, and SOD128's ultra-low 1 mm height - making it optimal for space-constrained, high-temperature automotive modules where thermal derating and board thickness are critical constraints.

FAQ
What is the maximum clamping voltage of PTVS15VP1UTP-QX under standard test conditions?
The clamping voltage VCL is 24.4 V, measured at a peak pulse current IPPM of 24.6 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 circuits during surge events.
Does PTVS15VP1UTP-QX require orientation-specific PCB layout?
Yes - the device is unidirectional and polarity-sensitive. Pin 1 (cathode) must connect to the line being protected (e.g., 12 V rail), and Pin 2 (anode) must connect to ground. The cathode is marked by a visible bar on the package body; incorrect orientation will prevent clamping and may cause catastrophic failure during overvoltage events.
How does PTVS15VP1UTP-QX perform at elevated junction temperatures?
It maintains full 600 W peak pulse power capability up to Tj = 150 °C, then derates linearly to ~400 W at Tj = 185 °C (per Fig. 2 in datasheet). Its positive temperature coefficient (+14.1 mV/K) ensures VBR and VCL increase predictably with temperature - avoiding premature conduction or loss of margin in hot environments.
Is PTVS15VP1UTP-QX compatible with lead-free reflow soldering processes?
Yes - it is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), with peak temperature tolerance up to 260 °C. The CFP5 package supports both reflow and wave soldering; recommended footprint dimensions (4.4 mm × 2.1 mm pad length per Fig. 7) ensure mechanical reliability and thermal performance in high-volume automotive manufacturing.
