Product details
Overview
PTVS11VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features 11 V reverse standoff voltage (VRWM), 13.5 V maximum clamping voltage (VCL) at 22.0 A peak pulse current (IPPM), and 0.005 µA reverse leakage at VRWM - optimized for compact, high-reliability protection in space-constrained industrial and automotive power supply circuits.
For engineers reviewing the PTVS11VS1UR,115 datasheet, PTVS11VS1UR,115 pinout, PTVS11VS1UR,115 application, or PTVS11VS1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (Rth(j-sp) = 18 K/W), AEC-Q101 qualification status, and compatibility with standard SOD123W reflow footprints.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device in series with the protected line and ground, triggering when transient voltage exceeds its 11 V standoff threshold. Its breakdown voltage (VBR) is specified at 12.2–13.5 V (min–max) with 1 mA test current, ensuring precise turn-on behavior before downstream IC damage occurs.
The device complies with IEC 61643-321 for 10/1000 µs surge waveforms and delivers 400 W peak pulse power (PPPM) at Tj = 25 °C, derating to ~220 W at 125 °C per Fig. 2. Its cathode-anode polarity and marking bar orientation are fixed per SOD123W mechanical outline, requiring correct PCB layout alignment for functional protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 11 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin |
| VCL @ IPPM | 13.5 V at 22.0 A - clamped voltage during 10/1000 µs surge; limits stress on downstream 12 V logic or MCU inputs |
| PPPM | 400 W - peak surge power handling per IEC 61643-321; enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients |
| IRM | 0.005 µA at VRWM - ultra-low leakage ensures minimal standby current drain in battery-powered systems |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; supports reliable power dissipation on standard FR4 PCBs |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HBM ESD (>4 kV), and 30 kV contact discharge |
Pinout & Package
PTVS11VS1UR,115 uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, 1 mm max height, with flat leads optimized for automated placement and reflow soldering. The cathode is marked by a visible bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or low-side reference; carries full surge current during clamping event |
| 2 | Anode (A) | Connected to protected line (e.g., 12 V rail); reverse-biased during normal operation; forward-conducts during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD package | 1 mm max height enables use in ultra-thin modules and dense automotive ECUs without mechanical interference |
| High surge robustness | Withstands 50 A non-repetitive forward surge (IFSM, 8.3 ms half-sine), supporting load-dump immunity in 12 V vehicle systems |
| Automotive-qualified reliability | AEC-Q101 qualified per revision history v.4 (Dec 2025), confirming suitability for engine control, body electronics, and ADAS power domains |
| Precision clamping tolerance | VBR min/max spread of 12.2–13.5 V ensures consistent turn-on across production lots, reducing design margin uncertainty |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 12 V battery-supplied microcontroller power input in engine control unit exposed to ISO 7637-2 load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between VCC and GND, activated within nanoseconds of overvoltage onset. Use Value: Limits voltage to ≤13.5 V during 22 A surge, preventing latch-up or gate oxide damage in 3.3 V/5 V logic powered from same rail. |
Use Scenario: 24 V DC digital input channel on programmable logic controller receiving signals from field sensors in factory automation. IC Role / Device Role / Timing Role: Reverse-biased TVS shunting induced surges from long cable runs or relay switching noise.

IC Role / Device Role / Timing Role: Fast-response TVS absorbing coupling noise from primary-side MOSFET switching and external EFT bursts. Use Value: 400 W PPPM rating sustains repeated 10/1000 µs surges without degradation, extending converter lifetime in harsh environments. |
Use Scenario: USB-C PD input stage of smart home gateway where 5–20 V input rails face ESD and hot-plug transients. IC Role / Device Role / Timing Role: Standoff-rated TVS on VBUS line, selected for 11 V VRWM to avoid conduction during nominal 12 V operation. Use Value: 18 K/W Rth(j-sp) enables effective heat transfer to copper pour, maintaining <150 °C junction temp during sustained surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | DO-214AC package (larger: 4.5 × 2.7 × 2.2 mm); 11.1 V VRWM; 18.2 V VCL @ 21.3 A; 400 W PPPM | Higher profile and thermal resistance (Rth(j-a) ≈ 50 K/W vs. 18 K/W); less suitable for ultra-thin automotive modules | Select when legacy DO-214AC footprint is fixed and board space is not constrained. |
| TPSMA6L11A | SMA package (same 4.5 × 2.7 mm footprint); 11.1 V VRWM; 17.5 V VCL @ 22.9 A; 600 W PPPM | Higher clamping voltage increases risk to 12 V logic; higher PPPM requires larger thermal relief but offers greater surge headroom | Prefer when surge threat level exceeds IEC 61643-321 Class II and board layout allows SMA thermal pads. |
Compared with SMAJ11A and TPSMA6L11A, PTVS11VS1UR,115 provides superior board-level integration via its 1 mm height and lower Rth(j-sp), making it optimal for next-generation automotive and industrial modules where volume and thermal performance are critical.

FAQ
Is PTVS11VS1UR,115 qualified for automotive use per AEC-Q101?
Yes. Per the December 2025 revision history (v.4), PTVS11VS1UR,115 is explicitly listed among the 33 types upgraded to standard AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature operating life, and ESD per MIL-STD-883 HBM (>4 kV) and IEC 61000-4-2 (30 kV contact discharge).
What is the maximum clamping voltage under a 10/1000 µs surge?
At rated peak pulse current (IPPM = 22.0 A), the maximum clamping voltage (VCL) is 13.5 V, measured per IEC 61643-321. This value is guaranteed across temperature (–55 °C to 150 °C) and represents worst-case voltage seen by protected circuitry during standardized surge testing.
How does the SOD123W package affect thermal performance?
The SOD123W package achieves Rth(j-sp) = 18 K/W to the cathode solder point due to its low-profile copper leadframe and direct thermal path. When mounted per Nexperia's recommended reflow footprint (Fig. 6), this enables efficient heat transfer to PCB copper, sustaining 400 W surges without exceeding 150 °C junction temperature in typical industrial layouts.
Can PTVS11VS1UR,115 replace PTVS10VS1UR in a 12 V system?
No - PTVS11VS1UR,115 has 11 V VRWM versus 10 V for PTVS10VS1UR, resulting in higher turn-on threshold and reduced margin against normal 12 V rail variation. Use only if system tolerances allow ≥1 V headroom above nominal voltage; otherwise, VCL rise (13.5 V vs. 12.3 V) may compromise downstream 12 V ICs.
