Product details
Overview
PTVS10VP1UTP-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. It features 10 V reverse standoff voltage (VRWM), 17.0 V clamping voltage (VCL) at 35.3 A peak pulse current (IPPM), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS10VP1UTP-QX datasheet, PTVS10VP1UTP-QX pinout, PTVS10VP1UTP-QX application, or PTVS10VP1UTP-QX equivalent, this device is selected for robust ESD/ISO 7637-2 surge suppression in engine control units, battery management systems, and 12 V automotive subsystems where thermal stability and AEC-Q101 compliance are mandatory.
Technical Context
This unidirectional TVS diode operates as a clamping device: under normal bias it presents high impedance (>10⁹ Ω at VRWM), then rapidly avalanches at breakdown voltage (VBR = 11.1–12.3 V) to limit transients. Its IEC 61643-321 (10/1000 μs) rated peak pulse power remains stable up to 185 °C junction temperature, with derating shown in Fig. 2.
The SOD128 package enables low-profile mounting (1 mm height) with optimized thermal resistance - Rth(j-sp) = 12 K/W to solder point - supporting reliable operation in under-hood environments. Cathode-marked polarity ensures correct orientation during automated placement and ensures proper clamping direction relative to protected IC supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V automotive systems. |
| VCL @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 10/1000 μs surge; ensures downstream ICs (e.g., MCU I/O, CAN transceivers) remain below absolute maximum ratings. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321; supports ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 5a/b (load dump) waveforms. |
| IRM | 0.005 μA at VRWM - Ultra-low leakage preserves battery standby current in always-on modules like body control units. |
| Tj max | 185 °C - Junction temperature limit validated per AEC-Q101; enables direct placement near hot components (e.g., power MOSFETs, DC-DC converters). |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2); protects against human-body-model and system-level electrostatic events without external shielding. |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat leads with cathode marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); clamping occurs when voltage exceeds VRWM relative to anode (GND). |
| 2 | Anode (A) | Connected to system ground; forms low-impedance path for surge current during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and temperature cycling - eliminates qualification overhead for Tier 1 suppliers. |
| High-temperature stability | Rated PPPM maintained up to Tj = 185 °C (Fig. 2); avoids derating penalties in engine bay or powertrain modules. |
| Low-profile SMD package | 1 mm height enables placement under connectors or in space-constrained ECUs without interfering with mechanical shields or housings. |
| Ultra-low IRM | 5 nA leakage at 10 V VRWM minimizes quiescent current drain - critical for >10-year battery-backed telematics modules. |
| Robust ESD immunity | ±30 kV contact discharge rating exceeds ISO 10605 requirements, reducing need for secondary ESD protection layers. |
Applications
| Engine Control Unit (ECU) Power Rail Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Suppresses load-dump transients (ISO 7637-2 Pulse 5a/b) on 12 V supply lines feeding microcontrollers and analog sensors. IC Role / Device Role: Unidirectional clamping TVS placed between battery input and DC-DC converter input stage. Use Value: Limits VIN to ≤17.0 V during 100 V/400 ms surges, preventing latch-up or damage to 24 V-tolerant regulators and LDOs. |
Use Scenario: Protects LIN bus transceivers and door module MCUs from ESD and coupled noise in interior lighting and window lift circuits. IC Role / Device Role: Localized TVS on each LIN node's VCC line, mounted adjacent to transceiver IC. Use Value: Withstands repeated ±30 kV contact discharges while maintaining <5 nA leakage - preserving sleep-mode current budget. |
| Battery Management System (BMS) Cell Monitoring | Start-Stop System Power Conditioning |
Use Scenario: Shields precision ADC inputs and reference buffers in cell voltage monitoring ICs from switching noise and relay bounce. IC Role / Device Role: Low-capacitance TVS (Cd ≈ 100 pF at 0 V) placed at analog front-end of BMS ASIC. Use Value: Clamps fast transients (<1 ns rise time) without distorting mV-level cell voltage measurements due to minimal parasitic capacitance. |
Use Scenario: Guards buck-boost converter inputs during cranking events where battery voltage dips to 3.5 V and spikes to 16 V. IC Role / Device Role: Bidirectional protection not required; unidirectional PTVS10VP1UTP-QX used with series Schottky for reverse polarity + overvoltage. Use Value: Maintains 10 V VRWM margin above nominal 12 V while surviving 185 °C ambient - enabling direct PCB mounting near power inductors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-Q | Lower PPPM (400 W), higher VCL (18.2 V at 24.6 A), same SOD-123 package but no AEC-Q101 certification. | Limited to non-safety-critical cabin modules; unsuitable for powertrain or under-hood use due to 150 °C Tj max. | Select only if cost sensitivity outweighs thermal margin and automotive qualification requirements. |
| TPSMA6L10A | Same 600 W PPPM and 10 V VRWM, but rated for 175 °C Tj and qualified to AEC-Q101 Rev G; slightly higher VCL (17.5 V). | Approved for ADAS domain controllers; requires larger PCB footprint (SMA package, 2.5 mm height). | Choose when higher mechanical robustness or legacy SMA footprint compatibility is prioritized over ultra-low profile. |
Compared with SMAJ10A-Q, PTVS10VP1UTP-QX delivers 50 % higher surge power and full AEC-Q101 compliance for powertrain use; versus TPSMA6L10A, it reduces board height by 60 % while maintaining identical electrical protection levels and thermal capability.

FAQ
What is the clamping voltage of PTVS10VP1UTP-QX under a 10/1000 μs surge?
The clamping voltage (VCL) is 17.0 V at 35.3 A peak pulse current (IPPM), measured per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to 185 °C) and defines the maximum voltage seen by downstream circuitry during standardized surge events.
Does PTVS10VP1UTP-QX require a heatsink for 600 W pulse handling?
No external heatsink is required. The SOD128 package achieves Rth(j-sp) = 12 K/W to solder point, allowing full 600 W pulse dissipation via standard PCB copper land patterns (e.g., 1 cm² cathode pad on FR4). Thermal performance is validated per Fig. 2 and Table 6.
How does the marking code 'CE' correspond to PTVS10VP1UTP-QX?
'CE' is the top-side laser marking for PTVS10VP1UTP-QX per Table 4. The bar adjacent to pin 1 indicates the cathode terminal. This marking is consistent across all variants in the PTVSxP1UTP-Q series and aligns with Nexperia's SOD128 package orientation standard.
Can PTVS10VP1UTP-QX replace bidirectional TVS diodes in automotive CAN bus protection?
No - it is unidirectional and intended for power rail protection only. CAN bus protection requires bidirectional clamping to handle both positive and negative transients on differential lines. Use dedicated bidirectional TVS arrays (e.g., PUSB3FR4) for CAN FD or LIN physical layer protection.
