Product details
Overview
PTVS11VS1UTR-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 11 V reverse standoff voltage (VRWM), 18.2 V clamping voltage (VCL) at 22 A peak pulse current, and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS11VS1UTR-Q datasheet, PTVS11VS1UTR-Q pinout, PTVS11VS1UTR-Q application, or PTVS11VS1UTR-Q equivalent, this device supports AEC-Q101-compliant automotive ECU power supply protection, industrial 12 V bus surge suppression, and high-reliability 11 V rail clamping where low-profile mounting and thermal stability are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds VRWM = 11 V. Its I-V characteristic follows standard TVS response per IEC 61643-321 (10/1000 μs waveform), delivering precise clamping at VCL = 18.2 V under IPPM = 22 A.
Thermal design is enabled by Rth(j-sp) = 18 K/W to cathode solder point and rated operation up to Tamb = 185 °C. The device maintains stable PPPM = 400 W across Tj ≤ 150 °C, with derating above that per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 400 W - Sustains 10/1000 μs transients without failure in automotive load-dump or ISO 7637-2 scenarios |
| Reverse Standoff Voltage (VRWM) | 11 V - Blocks normal 12 V system operation while triggering only during overvoltage events |
| Clamping Voltage (VCL) | 18.2 V at IPPM = 22 A - Limits downstream IC stress to safe levels during 12 V rail surges |
| Reverse Leakage (IRM) | 0.005 μA at VRWM - Negligible quiescent current draw in battery-sensitive automotive modules |
| Junction Temperature (Tj) | 185 °C max - Enables placement near hot components (e.g., power MOSFETs, DC-DC converters) |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm footprint with 1 mm height for space-constrained PCB layouts |
| AEC-Q101 Qualified | Yes - Validated for automotive use including temperature cycling, HTRB, and ESD (±30 kV contact) |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package with flat leads and 1 mm profile; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path during avalanche conduction |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Operation | Tj up to 185 °C enables direct placement on engine-control PCBs without thermal derating penalties |
| Low-Profile Mounting | 1 mm height allows integration beneath shields or in stacked multi-layer automotive modules |
| Automotive Qualification | AEC-Q101 compliance ensures reliability across temperature cycling, humidity, and mechanical shock profiles |
| Precision Clamping | VBR = 12.2–13.5 V guarantees consistent turn-on within ±5 % of nominal 11 V rail |
| ESD Robustness | ±30 kV contact discharge rating protects against assembly-line and field ESD events |
Applications
| Automotive Engine Control Unit (ECU) | Industrial 12 V DC Power Distribution |
|---|---|
Use Scenario: Protection of microcontroller power inputs against load dump transients in gasoline/diesel engine ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS clamps 12 V rail spikes to ≤18.2 V within nanoseconds, preserving MCU VDD integrity. Use Value: Prevents brownout resets and latch-up during ISO 7637-2 Pulse 5a (12 V system), enabling ASIL-B compliant designs. |
Use Scenario: Surge suppression on DIN-rail-mounted 12 V PLC power inputs exposed to inductive switching noise. IC Role / Device Role / Timing Role: Fast-response avalanche diode shunts 400 W transients away from downstream DC-DC regulators and I/O drivers. Use Value: Maintains <1 μA leakage at 11 V, eliminating standby current concerns in always-on industrial controllers. |
| Automotive Body Control Module (BCM) | High-Temperature Sensor Interface |
Use Scenario: Input protection for LIN bus transceivers and LED driver ICs in under-hood BCMs. IC Role / Device Role / Timing Role: Cathode-to-rail configuration absorbs reverse polarity and jump-start transients before they reach sensitive analog front-ends. Use Value: 185 °C junction rating permits placement adjacent to 12 V power switches without thermal margin loss. |
Use Scenario: Overvoltage clamping for RTD or thermocouple signal conditioning circuits in exhaust gas recirculation (EGR) sensors. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS guards precision op-amp inputs against EMI-induced rail excursions. Use Value: 0.005 μA IRM at VRWM avoids measurement offset errors in µV-level sensor amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-Q | Lower PPPM = 400 W but lower VRWM tolerance (10.5–11.6 V vs. 11 V typ), higher VCL = 19.0 V at 21.7 A | Less precise clamping margin for 12 V systems requiring tight VDD headroom | Prefer PTVS11VS1UTR-Q when VCL ≤18.2 V is required to protect 20 V-rated downstream ICs |
| TPSMF11A | Same VRWM and VCL specs, but SOD-123 package (not SOD123W); Rth(j-a) = 220 K/W vs. 70 K/W for PTVS11VS1UTR-Q | Limited thermal performance in high-ambient environments (>125 °C ambient) | Choose PTVS11VS1UTR-Q for under-hood applications where junction temperature must stay ≤185 °C |
Compared with SMAJ11A-Q and TPSMF11A, PTVS11VS1UTR-Q delivers tighter VCL control, superior thermal resistance to solder point (18 K/W), and guaranteed 185 °C operation-making it optimal for space- and temperature-constrained automotive power nodes.

FAQ
What is the maximum clamping voltage for PTVS11VS1UTR-Q under standard test conditions?
The clamping voltage (VCL) is 18.2 V measured at 22 A peak pulse current (IPPM) using the 10/1000 μs waveform per IEC 61643-321. This value is confirmed in Table 8 of the datasheet for Tj = 25 °C and represents the maximum voltage seen by downstream circuitry during a defined surge event.
Is PTVS11VS1UTR-Q suitable for bidirectional transient protection?
No - PTVS11VS1UTR-Q is a unidirectional TVS diode, intended only for reverse-polarity and overvoltage protection on positive rails. It does not suppress positive transients on grounded lines or AC signals; a bidirectional variant like PTVS11VS1UTR-QB would be required for those use cases.
How does the SOD123W package improve thermal performance over standard SOD-123?
The SOD123W (CFP3) package features an enlarged cathode pad and optimized internal thermal path, achieving Rth(j-sp) = 18 K/W to solder point - significantly lower than typical SOD-123's ~40–60 K/W. This enables higher sustained power dissipation in high-ambient automotive environments.
Can PTVS11VS1UTR-Q replace older P6SMB11A in existing designs?
Only with layout and thermal validation: both have VRWM = 11 V and similar VCL, but PTVS11VS1UTR-Q uses SOD123W (2.6 × 1.7 mm) versus P6SMB11A's DO-214AA (4.5 × 3.2 mm). The smaller footprint requires updated stencil and reflow profile, and its 185 °C rating exceeds P6SMB11A's 150 °C limit.
