Product details
Overview
PTVS9V0S1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features 9.0 V reverse standoff voltage (VRWM), 15.4 V clamping voltage (VCL) at 5 mA, 26.0 A peak pulse current (IPPM), junction temperature rating up to 185 °C, and AEC-Q101 qualification.
For engineers reviewing the PTVS9V0S1UTR-Q datasheet, PTVS9V0S1UTR-Q pinout, PTVS9V0S1UTR-Q application, or PTVS9V0S1UTR-Q equivalent, this device supports robust ESD/EMI suppression in 12 V automotive subsystems, battery management inputs, and industrial DC power interfaces where thermal stability and low-profile mounting are critical.
Technical Context
This unidirectional TVS diode operates as a clamping device in series with the protected line and ground, triggering when transient voltage exceeds its breakdown threshold (VBR = 10.0–11.1 V). Its low 0.005 µA reverse leakage at VRWM ensures minimal standby power loss in always-on circuits.
The device uses silicon planar technology with optimized junction design to sustain 400 W peak pulse power under IEC 61643-321 10/1000 µs waveform, while maintaining stable clamping performance across −55 °C to +185 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 9.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC operating margin for 12 V nominal systems. |
| VBR (min/typ/max) | 10.0 / 10.55 / 11.10 V - Breakdown voltage range at 5 mA test current; determines precise turn-on threshold under surge conditions. |
| VCL | 15.4 V - Clamped voltage at 5 mA IZ; limits downstream component stress during transients in automotive CAN/LIN bus or sensor supply lines. |
| IPPM | 26.0 A - Peak pulse current capability at 10/1000 µs waveform; supports protection against ISO 7637-2 Pulse 1, 2a, and 5a surges. |
| Tj max | 185 °C - Maximum junction temperature rating; enables reliable operation near engine control units and power converters without derating. |
| ESD rating | ±30 kV contact discharge (IEC 61000-4-2); eliminates need for external ESD staging in infotainment and ADAS interface ports. |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to solder point; enables efficient heat transfer to PCB copper pour in compact layouts. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode-marked with bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); polarity-sensitive connection-reverse orientation causes short-circuit failure. |
| 2 (A) | Anode | Connected to system ground; forms clamping path during overvoltage events; requires low-inductance ground plane routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress-test standard; eliminates requalification effort for Tier 1 ECUs and body controllers. |
| 1 mm profile | Enables placement under connectors or in tight board spaces; avoids mechanical interference in stacked modules. |
| 185 °C junction rating | Supports direct mounting on high-temperature PCB zones (e.g., near DC-DC converters), reducing thermal interface layers. |
| 0.005 µA IRM at VRWM | Minimizes quiescent current drain in battery-backed systems (e.g., telematics sleep mode), extending runtime. |
| 400 W PPPM | Handles repeated load-dump transients without degradation; meets ISO 16750-2 Class D requirements for 12 V systems. |
Applications
| Automotive Power Rail Protection | Industrial DC Input Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units exposed to ISO 7637-2 load dump pulses. IC Role / Device Role: Unidirectional clamping TVS placed between VCC and GND, shunting surge energy away from LDO and MCU VDD pins. Use Value: Limits voltage to ≤15.4 V during 100 V/100 ms transients, preventing latch-up or oxide breakdown in 3.3 V logic supplies. |
Use Scenario: Safeguarding 24 V PLC input terminals against field-wiring induced surges and inductive kickback. IC Role / Device Role: Primary overvoltage clamp on signal/power input stage, upstream of TVS arrays and filtering capacitors. Use Value: Withstands 26 A peak pulses without parametric shift, enabling single-device protection instead of multi-stage designs. |
| Automotive Sensor Interface Protection | High-Temperature Battery Management |
|
Use Scenario: Shielding LIN bus transceiver VBAT pins in ambient temperatures up to +125 °C under hood applications. IC Role / Device Role: Localized TVS adjacent to transceiver IC, minimizing trace inductance to preserve clamping speed. Use Value: Maintains <1 µA leakage at 125 °C ambient, avoiding false wake-up in low-power sensor nodes. |
Use Scenario: Guarding cell monitor IC supply inputs in EV battery packs where local temperatures reach 105 °C continuously. IC Role / Device Role: Secondary protection after fuse and primary MOV, providing fast, precise clamping for analog front-end rails. Use Value: Stable 10.55 V typical VBR across full temperature range ensures consistent trip margin despite thermal drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Lower PPPM (400 W same), but higher VCL = 14.4 V at 23.5 A; Tj max = 150 °C; no AEC-Q101 qualification. | Acceptable for non-automotive industrial use; unsuitable for under-hood automotive due to lower temperature rating. | Select only if AEC-Q101 compliance and >150 °C operation are not required. |
| TPSMF9.0A | Same VRWM and VCL, but lower PPPM = 200 W; Tj max = 175 °C; AEC-Q101 qualified; larger SOD-123FL package (1.6 mm height). | Marginally adequate for light-duty automotive; insufficient for repeated load dump; taller profile may interfere with shielding cans. | Choose only when cost is prioritized over surge endurance and board height constraints. |
Compared with SMAJ9.0A and TPSMF9.0A, PTVS9V0S1UTR-Q delivers superior thermal resilience (185 °C), guaranteed 400 W surge handling, and AEC-Q101 validation-making it the only option qualified for demanding engine bay deployments requiring zero derating.

FAQ
What is the maximum clamping voltage of PTVS9V0S1UTR-Q under surge conditions?
The clamping voltage (VCL) is 15.4 V measured at 5 mA test current per IEC 61643-321. Under full 400 W 10/1000 µs surge, actual clamped voltage remains ≤15.4 V up to 26 A peak current, verified across −55 °C to +150 °C junction temperature range.
Can PTVS9V0S1UTR-Q replace PTVS9V0S1UR without redesign?
No-PTVS9V0S1UR is not AEC-Q101 qualified and has lower thermal rating (Tj max = 150 °C vs. 185 °C). Substitution requires validation of surge endurance at elevated temperature and review of automotive qualification documentation for functional safety compliance.
How does the SOD123W package affect thermal performance compared to SMA?
The SOD123W's 1 mm height and optimized thermal pad reduce Rth(j-sp) to 18 K/W-30% lower than standard SMA packages. This allows faster heat dissipation into PCB copper, supporting sustained operation at 185 °C junction temperature without external heatsinking.
Is PTVS9V0S1UTR-Q suitable for bidirectional signal line protection?
No-it is strictly unidirectional. For bidirectional data lines like USB or RS-485, a symmetric TVS array or dedicated bidirectional device (e.g., PTVS3V3S2UTR-Q) must be used; reverse-bias operation would forward-conduct and fail catastrophically.
