Product details
Overview
PTVS30VS1UR,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 a 30 V reverse standoff voltage (VRWM), 36.8 V maximum clamping voltage (VCL) at 48.4 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - enabling robust protection of 3.3–5 V logic interfaces and 24–36 V industrial control inputs.
For engineers reviewing the PTVS30VS1UR,115 datasheet, PTVS30VS1UR,115 pinout, PTVS30VS1UR,115 application, or PTVS30VS1UR,115 equivalent, this device is selected for high-energy surge immunity in space-constrained PCB layouts where low-profile mounting (<1 mm height), AEC-Q101 qualification, and IEC 61643-321 (10/1000 µs) compliance are required.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode with sharp breakdown knee and fast response (<1 ns). Its junction-to-solder-point thermal resistance is 18 K/W, supporting reliable energy dissipation during repetitive transients when mounted on standard FR4 with cathode pad enhancement.
The device complies with IEC 61643-321 using 10/1000 µs waveform testing and delivers 400 W rated peak pulse power (PPPM) at Tj = 25 °C - derating to ~220 W at 125 °C per Fig. 2. Breakdown voltage (VBR) is specified at 1 mA IR, with typical value 35.1 V and max 36.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - maximum continuous reverse operating voltage before clamping begins; sets threshold for protecting 24 V nominal systems. |
| VCL @ IPPM | 36.8 V at 48.4 A - clamped voltage during 10/1000 µs surge; ensures downstream ICs see <37 V under worst-case 400 W transient. |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321; enables suppression of high-energy surges like ISO 7637-2 Pulse 1/2a/5a. |
| IRM | 0.001 µA at VRWM - ultra-low leakage preserves battery life and avoids false triggering in always-on circuits. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point; allows >90% of surge energy to be conducted into PCB copper via cathode tab. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides system-level ESD immunity without additional discrete protection. |
Pinout & Package
PTVS30VS1UR,115 uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode-marked with bar. Mounting requires optimized thermal pad on cathode side per Fig. 6 footprint (4.4 mm × 2.9 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +24 V rail); marking bar identifies this terminal; carries full IPPM current during clamping. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to GND during overvoltage event; must be low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (HTOL, TC, UHAST), supporting use in engine control, body electronics, and ADAS power domains. |
| 1 mm profile | Enables placement beneath connectors or in tight board-to-board spacing; reduces mechanical stress vs. taller SMC/SMA packages. |
| 400 W PPPM rating | Handles 10/1000 µs surges up to 48.4 A - sufficient for ISO 16750-2 Load Dump simulations in 12 V/24 V systems. |
| 0.001 µA IRM | Minimizes standby current draw in battery-powered sensors and IoT nodes; eliminates need for series resistors to limit leakage. |
| SOD123W footprint | Compatible with standard reflow profiles (J-STD-020); supports automated assembly and wave soldering with defined land patterns (Fig. 6/7). |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24 V DC input channel on programmable logic controller exposed to inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Unidirectional TVS placed between field input and signal conditioning IC to clamp transients before they reach op-amps or microcontroller GPIO. Use Value: Limits voltage to ≤36.8 V during 48.4 A surge, preventing latch-up or gate oxide damage in downstream analog front-end components. |
Use Scenario: Power supply rail feeding interior lighting control unit in vehicle cabin, subject to load dump and jump-start events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V/24 V main rail upstream of LDO regulators and CAN transceivers. Use Value: Absorbs 400 W surge energy within 1000 µs, maintaining rail integrity below 37 V to avoid brownout reset of MCU and communication peripherals. |
| Smart Meter Power Input | Factory Automation Sensor Node |
Use Scenario: M-Bus or RS-485 interface powered from external 36 V supply in utility meter, exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: First-stage protection on DC input before DC-DC converter and isolation barrier. Use Value: Clamps 10/1000 µs transients to 36.8 V while dissipating full 400 W, allowing downstream converter to remain operational without shutdown. |
Use Scenario: Battery-powered vibration sensor node deployed near motor drives, experiencing repetitive EFT bursts and conducted noise. IC Role / Device Role / Timing Role: Low-leakage TVS on 3.3 V supply rail to suppress sub-microsecond ESD and EFT events. Use Value: 0.001 µA IRM prevents measurable battery drain over 10-year deployment; 30 kV ESD rating eliminates need for secondary protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | DO-214AA package (4.5 mm height); 600 W PPPM; 48.4 V VCL @ 43.5 A; 1 µA IRM. | Larger footprint and height; higher clamping voltage reduces margin for 3.3 V logic protection. | Select when higher surge rating is needed and board height >1 mm is acceptable. |
| SMF30A | SOD-123 package (same outline but non-AEC-Q101); 200 W PPPM; 48.4 V VCL @ 21.7 A; 1 µA IRM. | Half the surge power rating; not qualified for automotive use; lower thermal performance (Rth(j-sp) ~30 K/W). | Select for cost-sensitive consumer applications where AEC-Q101 and 400 W are not required. |
Compared with SMBJ30A and SMF30A, PTVS30VS1UR,115 uniquely combines AEC-Q101 qualification, 400 W surge capability, 1 mm profile, and 0.001 µA leakage - making it optimal for space-constrained automotive and industrial designs requiring both reliability and low standby loss.

FAQ
What is the maximum clamping voltage of PTVS30VS1UR,115 under standard test conditions?
The maximum clamping voltage (VCL) is 36.8 V at 48.4 A peak pulse current (IPPM), measured per IEC 61643-321 with 10/1000 µs waveform at Tj = 25 °C. This value is guaranteed across production lots and defines the upper voltage limit seen by protected circuitry during surge events.
Is PTVS30VS1UR,115 qualified for automotive applications?
Yes - PTVS30VS1UR,115 is AEC-Q101 qualified per the revision history (v.4, Dec 2025), confirming successful completion of stress tests including HTOL, temperature cycling, and unbiased HAST. It is approved for use in automotive power distribution, body electronics, and infotainment systems.
How does the SOD123W package improve thermal performance compared to standard SOD-123?
The SOD123W (CFP3) package features an extended cathode tab that lowers junction-to-solder-point thermal resistance to 18 K/W - 40% better than standard SOD-123 (~30 K/W). This enables more efficient heat transfer to PCB copper, sustaining higher surge repetition rates without thermal runaway.
Can PTVS30VS1UR,115 replace PTVS30VS1U,115 in existing designs?
No - PTVS30VS1UR,115 and PTVS30VS1U,115 are distinct part numbers. The "R" suffix denotes the SOD123W (CFP3) package with enhanced thermal pad; the "U" variant uses standard SOD-123. Mechanical and thermal characteristics differ significantly - redesign of footprint and thermal relief is required for substitution.
