Product details
Overview
PTVS9V0S1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) surface-mount package, designed for clamping transient overvoltages on DC power rails. It features VRWM = 9.0 V, VBR(min) = 10.00 V at IR = 1 mA, VCL(max) = 15.4 V at IPPM = 26.0 A (10/1000 μs), and IRM ≤ 0.005 μA - enabling robust protection of 9 V supply lines in industrial control modules.
For engineers reviewing the PTVS9V0S1UR,115 datasheet, PTVS9V0S1UR,115 pinout, PTVS9V0S1UR,115 application, or PTVS9V0S1UR,115 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD tolerance, peak pulse current capability under IEC 61643-321 waveform, thermal resistance to PCB copper area, and compatibility with automated SMT reflow profiles for high-reliability power management designs.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche diode, triggering when transient voltage exceeds its breakdown threshold (VBR = 10.00–11.10 V). Its low clamping voltage (15.4 V max) limits stress on downstream 9 V-rated components during 10/1000 μs surges up to 26.0 A.
Thermal performance is defined by Rth(j-a) = 220 K/W (FR4, single-sided copper) and Rth(j-sp) = 18 K/W (cathode solder point), requiring careful PCB copper land design per Nexperia's SOD123W footprint guidelines to sustain repeated 400 W pulses without junction overheating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 9.0 V - maximum continuous reverse operating voltage before leakage rises significantly; sets upper limit for protected rail nominal voltage. |
| VBR (min) | 10.00 V at IR = 1 mA - guaranteed avalanche initiation threshold; ensures reliable turn-on before damage to 9 V logic supplies. |
| VCL (max) | 15.4 V at IPPM = 26.0 A - worst-case clamped voltage during full-rated surge; must stay below absolute max rating of downstream ICs. |
| PPPM | 400 W - rated peak pulse power per IEC 61643-321 (10/1000 μs); defines energy-handling capacity for transient suppression. |
| IRM | ≤ 0.005 μA at VRWM - ultra-low reverse leakage; prevents measurable quiescent current draw in battery-powered 9 V systems. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; enables effective heat transfer to PCB copper when mounted per recommended footprint. |
Pinout & Package
PTVS9V0S1UR,115 uses the SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile optimized for low-profile PCB layouts and automated placement. Cathode identified by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail (anode grounded); polarity critical for unidirectional clamping operation. |
| 2 (A) | Anode | Connected to system ground; forms return path for surge current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Handles IEC 61643-321 10/1000 μs transients up to 26.0 A without degradation - sufficient for automotive load-dump and industrial switching surges. |
| 1 mm package height | Enables use in space-constrained applications such as portable instrumentation and compact motor drive PCBs where Z-height is limited. |
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision history v.4), supporting deployment in non-safety-critical vehicle subsystems like body control modules. |
| Low IRM ≤ 0.005 μA | Minimizes standby power loss in always-on 9 V circuits - critical for long-life battery-backed sensors and remote monitoring nodes. |
Applications
| Industrial Power Rail Protection | DC Motor Drive Input Stage |
|---|---|
|
Use Scenario: Protecting 9 V auxiliary supply rails in PLC I/O modules exposed to inductive kickback from relay coils and solenoid drivers.

Use Value: Extends field lifetime by eliminating premature failure of DC-DC controllers due to repetitive sub-millisecond overvoltage events. |
Use Scenario: Protecting 9 V lighting control outputs in automotive BCMs driving LED strips and incandescent bulbs. IC Role / Device Role / Timing Role: Placed across switched 9 V output traces to clamp load-dump transients (ISO 7637-2 Pulse 5a) and inductive flyback. Use Value: Ensures compliance with OEM EMC requirements while maintaining functional safety for non-critical lighting functions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Lower PPPM = 400 W but higher VCL = 14.4 V (at 27.8 A), larger SMA package (4.5 mm × 2.7 mm), Rth(j-a) ≈ 50 K/W. | Less suitable for ultra-thin designs; requires more PCB area and offers inferior thermal dissipation in dense layouts. | Choose only if existing SMA footprint reuse is mandatory and 1.0 mm height constraint does not apply. |
| PTVS9V0S1UTR | Same electrical specs but in SOD-123 (not SOD123W); 1.3 mm height, no flat-lead geometry, Rth(j-a) ≈ 280 K/W. | Higher thermal resistance reduces surge repetition capability; incompatible with low-profile SMT assembly lines calibrated for SOD123W. | Select only if legacy SOD-123 tooling exists and thermal derating for intermittent surges is acceptable. |
Compared with SMAJ9.0A and PTVS9V0S1UTR, PTVS9V0S1UR,115 delivers identical 400 W surge rating in a 1.0 mm low-profile package with superior thermal coupling (Rth(j-sp) = 18 K/W), making it optimal for next-generation compact, high-density industrial and automotive electronics where board space and thermal management are critical.

FAQ
What is the maximum clamping voltage of PTVS9V0S1UR,115 under full-rated surge current?
The maximum clamping voltage (VCL) is 15.4 V at IPPM = 26.0 A, measured using the standardized 10/1000 μs current waveform per IEC 61643-321. This value represents the worst-case voltage seen by protected circuitry during a 400 W transient event and must be verified against downstream IC absolute maximum ratings.
Is PTVS9V0S1UR,115 qualified for automotive use?
Yes - PTVS9V0S1UR,115 is AEC-Q101 qualified per the latest revision history (v.4, December 2025), confirming its suitability for automotive applications including body electronics and infotainment power supplies, though not intended for safety-critical systems per Nexperia's legal disclaimer.
How does the SOD123W package improve thermal performance versus standard SOD-123?
The SOD123W (CFP3) package features flat leads and optimized thermal pad geometry, achieving Rth(j-sp) = 18 K/W - significantly lower than standard SOD-123's ~35 K/W - due to enhanced solder joint conduction from cathode tab to PCB copper, enabling higher surge repetition rates in thermally constrained designs.
Can PTVS9V0S1UR,115 be used in bidirectional configurations?
No - PTVS9V0S1UR,115 is a unidirectional TVS diode with anode and cathode terminals; it only clamps positive transients relative to ground. For bidirectional protection (e.g., data lines), a dedicated bidirectional TVS such as PTVS9V0S1UR,115's complementary dual-diode variant would be required.
