Product details
Overview
PTVS11VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature overvoltage protection in power rails. It features 11 V reverse standoff voltage (VRWM), 18.2 V clamping voltage (VCL) at 22 A peak pulse current, and operates up to 185 °C junction temperature - ideal for industrial power supply surge suppression.
For engineers reviewing the PTVS11VS1UTR datasheet, PTVS11VS1UTR pinout, PTVS11VS1UTR application, or PTVS11VS1UTR equivalent, key selection criteria include its 11 V VRWM tolerance, 400 W IEC 61643-321 (10/1000 µs) pulse rating, cathode-anode polarity marking, and thermal resistance of 70 K/W (junction-to-solder point) on ceramic PCB.
Technical Context
This unidirectional TVS diode uses silicon avalanche breakdown to clamp transient overvoltages above its 11 V standoff threshold. Its V-I characteristic exhibits sharp knee behavior with <0.005 µA reverse leakage at VRWM and 18.2 V clamping at 22 A IPPM, per IEC 61643-321 waveform.
Thermal design leverages low-profile SOD123W package with 1 mm height and optimized solder-point thermal path (Rth(j-sp) = 18 K/W), enabling stable operation at Tj ≤ 185 °C - critical for under-hood automotive auxiliary systems and industrial motor drive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 11 V - maximum continuous reverse operating voltage before clamping begins |
| VCL @ IPPM | 18.2 V at 22 A - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321 (10/1000 µs) |
| IRM | 0.005 µA - ultra-low leakage preserves battery-backed or low-power standby circuits |
| Tj max | 185 °C - enables placement near heat sources without derating in industrial environments |
| Rth(j-sp) | 18 K/W - low thermal resistance to solder point supports reliable power dissipation on compact PCBs |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's positive rail; clamping occurs when voltage exceeds VRWM + VBR |
| 2 | Anode (A) | Connected to ground or low-impedance return path; completes transient current path during surge |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates need for thermal derating in engine control units or solar inverters |
| Low-profile SMD package | 1 mm height - fits beneath low-clearance heatsinks and enables dense power board layouts |
| IEC 61643-321 compliance | 400 W pulse rating (10/1000 µs) - meets industrial surge immunity standards (e.g., IEC 61000-4-5) |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - protects against handling and system-level ESD events |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Suppressing load-dump transients on 12 V DC input rails of PLC power supplies. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and ground to clamp surges within 1 ns response time. Use Value: Limits voltage to ≤18.2 V during 22 A transients, preventing damage to upstream DC-DC controllers and LDOs. | Use Scenario: Protecting CAN transceiver power pins from battery line surges in BCM modules. IC Role / Device Role / Timing Role: Standoff-rated TVS on VCC rail, triggered only during >11 V overvoltage events. Use Value: Maintains <0.005 µA leakage to avoid battery drain while surviving 185 °C under-hood ambient. |
| Solar Inverter DC Link Protection | Motor Drive Gate Driver Supply |
Use Scenario: Safeguarding MPPT controller inputs against lightning-induced surges on PV string outputs. IC Role / Device Role / Timing Role: Primary clamping device on high-side DC input, coordinated with fuse and MOV.

IC Role / Device Role / Timing Role: Localized TVS at gate driver VDD pin, minimizing loop inductance with short trace routing. Use Value: 1 mm profile allows placement directly adjacent to SOIC-8 gate driver ICs without mechanical interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower PPPM (400 W same), but higher VCL (18.5 V), larger SMA package (2.4 mm height) | Less suitable for space-constrained designs; lower thermal performance (Rth(j-a) ≈ 90 K/W) | Select when legacy footprint compatibility outweighs height and thermal constraints |
| SMCJ11A | Same VRWM and VCL, but 1500 W PPPM and DO-214AB package (7.1 mm × 6.2 mm) | Over-specified for 400 W needs; occupies >5× PCB area; better for high-energy surges | Choose only if system-level testing requires margin beyond IEC 61000-4-5 Level 4 |
Compared with SMAJ11A and SMCJ11A, PTVS11VS1UTR delivers identical 11 V standoff and comparable clamping in a 1 mm low-profile package with superior thermal resistance to solder point - making it optimal for thermally dense, height-restricted industrial and automotive power nodes.

FAQ
What is the maximum clamping voltage for PTVS11VS1UTR at its rated peak pulse current?
The clamping voltage (VCL) is 18.2 V at 22 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions. This value ensures downstream components see no more than 18.2 V during a full 400 W transient event, preserving voltage margins for 12 V-rated ICs.
How does the SOD123W package affect thermal performance compared to standard SMA packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W to the cathode solder point - significantly lower than typical SMA packages (~45–60 K/W). Its 1 mm height and optimized copper pad layout enable faster heat transfer into the PCB, supporting sustained operation at 185 °C junction temperature without external heatsinking.
Is PTVS11VS1UTR suitable for automotive under-hood applications?
Yes - it is qualified for junction temperatures up to 185 °C and rated for 30 kV ESD (IEC 61000-4-2), making it appropriate for non-safety-critical under-hood locations such as body control module power inputs. However, it is not AEC-Q200 qualified; automotive safety systems require explicitly qualified alternatives.
What is the reverse leakage current at 11 V standoff and 150 °C junction temperature?
At VRWM = 11 V and Tj = 150 °C, the reverse leakage current (IRM) is ≤0.005 µA, per Table 8 of the datasheet. This ultra-low leakage prevents measurable power loss in always-on circuits and maintains accuracy in precision voltage monitoring paths.
