Product details
Overview
PTVS9V0P1UTP-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 VRWM = 9.0 V, VBR(min) = 10.00 V at 1 mA, VCL = 15.4 V at IPPM = 39.0 A (10/1000 µs), IRM ≤ 0.005 µA, and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS9V0P1UTP-QX datasheet, PTVS9V0P1UTP-QX pinout, PTVS9V0P1UTP-QX application, or PTVS9V0P1UTP-QX equivalent, key selection criteria include clamping voltage under 15.4 V at 39 A, AEC-Q101 qualification, 1 mm profile for space-constrained PCB layouts, and thermal resistance Rth(j-sp) = 12 K/W for solder-point cooling in engine control units.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-anode polarity, triggered when reverse voltage exceeds 9.0 V standoff level. Its breakdown occurs at 10.00–11.10 V (min–max), delivering precise overvoltage thresholding for 12 V automotive systems.
It conforms to IEC 61643-321 (10/1000 µs waveform) and supports ESD immunity per IEC 61000-4-2 (±30 kV contact/air) and MIL-STD-883 HBM (8 kV), enabling robust protection in harsh environments without external biasing or control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 9.0 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 10.00 V at 1 mA - Ensures reliable turn-on margin above system nominal rail |
| VCL | 15.4 V at 39.0 A - Limits downstream IC voltage stress during 10/1000 µs transients |
| PPPM | 600 W - Sustains high-energy surges without failure under defined pulse conditions |
| IRM | ≤ 0.005 µA at VRWM - Minimizes leakage-induced power loss in battery-sensitive circuits |
| Tj(max) | 185 °C - Enables placement near heat sources (e.g., power converters, ECUs) without derating |
| Rth(j-sp) | 12 K/W - Enables efficient thermal coupling to PCB copper via cathode tab for sustained surge handling |
Pinout & Package
The PTVS9V0P1UTP-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 reflow and wave soldering. Cathode identification is marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's higher-potential side (e.g., +12 V rail); carries full surge current during clamping |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance path to shunt transient energy away from load |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard, supporting PPAP and long-term reliability in vehicle ECUs |
| 1 mm package height | Enables integration beneath low-profile shields or in tight engine-bay PCB stacks without mechanical interference |
| 185 °C junction rating | Eliminates need for thermal derating in under-hood applications where ambient exceeds 125 °C |
| 30 kV ESD immunity | Withstands repeated contact/air discharge events without parameter shift or failure in assembly/test environments |
| SOD128 footprint | Standardized land pattern (per Fig. 7) ensures compatibility with existing automotive PCB manufacturing lines |
Applications
| Engine Control Unit (ECU) Power Rail Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protects microcontroller power inputs against load-dump transients (ISO 7637-2 Pulse 5a) and alternator ripple in gasoline/diesel engine compartments. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between 12 V supply and local LDO input, responding within nanoseconds to suppress spikes >15 V. Use Value: Maintains VCL ≤ 15.4 V under 39 A peak current, preventing brownout or latch-up of 5 V/3.3 V regulators downstream. | Use Scenario: Shields LIN bus transceivers and relay drivers from battery disconnect transients and ESD events during door module assembly and field operation. IC Role / Device Role / Timing Role: Standoff protector on 12 V auxiliary rail feeding BCM sub-circuits; activated only during overvoltage excursions. Use Value: IRM ≤ 0.005 µA avoids measurable quiescent current increase, preserving sleep-mode battery life over 15-year vehicle lifespan. |
| ADAS Camera Power Input | Electric Power Steering (EPS) Motor Driver Supply |
Use Scenario: Safeguards image sensor and serializer ICs from ignition-induced transients and hot-swap surges in front/rear camera modules mounted near engine or chassis grounds. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V input stage, positioned upstream of DC-DC converter to prevent cascaded failure. Use Value: 185 °C Tj rating allows direct mounting on same PCB layer as power inductors, reducing layout parasitics and improving clamping response. | Use Scenario: Protects gate drivers and current sense amplifiers from inductive kickback during EPS motor commutation and fault shutdown. IC Role / Device Role / Timing Role: Fast-response unidirectional TVS on high-side switch supply rail, clamping within 1 ns to limit dV/dt stress on MOSFET gates. Use Value: Rth(j-sp) = 12 K/W enables direct thermal coupling to large copper pour, sustaining repeated 600 W pulses without thermal runaway during steering assist cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ9.0A-Q | Higher VCL = 14.4 V at 38.2 A; larger DO-214AB package (2.5 mm height); same 600 W rating | Less suitable for ultra-low-profile automotive modules due to 2.5× taller package | Select when board height > 1.5 mm is acceptable and legacy DO-214AB footprint exists |
| TPSMA6L9.0A-Q | Lower PPPM = 400 W; identical SOD128 footprint; VCL = 14.4 V at 27.8 A | Insufficient for ISO 7637-2 Pulse 5a compliance requiring ≥600 W capability | Choose only for cost-sensitive non-load-dump applications with lower surge exposure |
Compared with SMCJ9.0A-Q and TPSMA6L9.0A-Q, the PTVS9V0P1UTP-QX uniquely combines 600 W surge capacity, 1 mm height, AEC-Q101 qualification, and 185 °C operation-making it the only option meeting all four requirements for next-generation compact, high-temperature automotive electronics.

FAQ
What is the maximum clamping voltage of PTVS9V0P1UTP-QX under standardized surge conditions?
The clamping voltage VCL is 15.4 V at a peak pulse current IPPM of 39.0 A, measured using the IEC 61643-321 10/1000 µs waveform. 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 PTVS9V0P1UTP-QX require any external biasing or control circuitry to function?
No. The PTVS9V0P1UTP-QX is a passive, two-terminal unidirectional TVS diode that operates autonomously. It remains in high-impedance standby mode below 9.0 V VRWM and transitions to low-impedance conduction within nanoseconds when reverse voltage exceeds its breakdown threshold-no power supply, enable signal, or driver circuit is needed.
How does the SOD128 package enhance thermal performance compared to standard SMA packages?
The SOD128 (CFP5) package features an exposed cathode tab that provides a direct thermal path to the PCB solder point, achieving Rth(j-sp) = 12 K/W-over 5× better than typical SMA packages (~65 K/W). This enables effective heat dissipation during repetitive 600 W surges without requiring additional heatsinking or thermal vias.
Is PTVS9V0P1UTP-QX compatible with lead-free reflow soldering profiles?
Yes. The device is qualified for standard IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260 °C. Its plastic package and internal construction withstand thermal cycling without delamination or parameter drift, and the recommended solder land pattern is documented in Figure 7 of the datasheet.
