Product details
Overview
PTVS64VS1UTR-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 VRWM = 64 V, VBR(min) = 71.1 V at IR = 1 mA, VCL = 103.0 V at IPPM = 3.9 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS64VS1UTR-Q datasheet, PTVS64VS1UTR-Q pinout, PTVS64VS1UTR-Q application, or PTVS64VS1UTR-Q equivalent, this device is selected for robust clamping in 48 V–60 V automotive subsystems, ESD-hardened sensor interfaces, and high-ambient industrial power management where thermal stability and AEC-Q101 qualification are mandatory.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for fast response (<1 ns) to transients per IEC 61643-321 (10/1000 µs waveform). Its unidirectional configuration enables integration on positive-rail protection paths without reverse-bias leakage concerns beyond 0.001 µA at VRWM.
The device's thermal design supports sustained operation at Tamb = 185 °C via low Rth(j-a) = 70 K/W on ceramic PCB and Rth(j-sp) = 18 K/W to cathode solder point-critical for under-hood ECUs and battery management modules requiring long-term reliability above 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 64 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR (min) | 71.1 V at IR = 1 mA - Guaranteed breakdown initiation threshold; ensures predictable turn-on during surge events. |
| VCL | 103.0 V at IPPM = 3.9 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress in 64 V rail protection. |
| PPPM | 400 W - Peak pulse power handling per IEC 61643-321; sustains high-energy transients without failure. |
| IRM | 0.001 µA at VRWM - Ultra-low reverse leakage preserves efficiency in always-on automotive circuits. |
| Tj max | 185 °C - Junction temperature limit enabling use in engine bay, transmission control, and high-ambient industrial environments. |
| AEC-Q101 | Qualified - Meets automotive discrete semiconductor stress test requirements for vibration, temperature cycling, and HBM ESD (8 kV). |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode-marked with bar. Optimized for automated placement and reflow soldering per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 64 V supply rail); carries surge current into ground path during clamping. |
| 2 (A) | Anode | Connected to system ground; completes conduction path when reverse voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous use at Tamb = 185 °C and Tj = 185 °C-enables placement near heat sources in automotive ECUs. |
| Low-profile mounting | 1.0 mm max package height-reduces board-level mechanical interference and improves airflow in dense power modules. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and battery disconnect units. |
| ESD robustness | 30 kV contact/air discharge (IEC 61000-4-2), 8 kV HBM-protects against assembly and field electrostatic events. |
| Thermal resistance optimization | Rth(j-sp) = 18 K/W to cathode solder point-enables efficient heat transfer to PCB copper pour in high-power surges. |
Applications
| Automotive Power Rail Protection | Industrial 48 V DC Power Distribution |
|---|---|
Use Scenario: Protecting 48 V–60 V battery-fed control modules (e.g., HVAC actuators, seat motor drivers) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp transients within 1 ns. Use Value: Limits peak voltage to ≤103 V during 3.9 A surge, preventing damage to 75 V-rated MOSFETs and MCU power supplies. |
Use Scenario: Safeguarding programmable logic controllers (PLCs) and industrial HMIs powered from 48 V DC bus against switching surges and lightning-induced spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power entry, coordinated with upstream fuses and filters. Use Value: Maintains <0.001 µA leakage at 64 V standoff, minimizing standby power loss in always-on monitoring circuits. |
| High-Temperature Sensor Interface Protection | Automotive Body Control Module (BCM) Input Protection |
Use Scenario: Shielding analog front-end inputs of exhaust gas temperature (EGT) or turbocharger pressure sensors exposed to under-hood ambient >150 °C. IC Role / Device Role / Timing Role: Local TVS mounted adjacent to connector pins to suppress ESD and cable discharge events. Use Value: Operates reliably at Tj = 185 °C without derating-eliminates need for thermal derating margins in compact sensor housings. |
Use Scenario: Protecting BCM microcontroller GPIOs and LIN/CAN transceiver power pins from battery reverse connection and jump-start transients. IC Role / Device Role / Timing Role: Secondary clamping device downstream of primary fuse, providing low-leakage backup protection. Use Value: 30 kV ESD rating prevents latch-up or gate oxide damage during service operations and manufacturing handling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-Q | Lower PPPM = 400 W but higher VCL = 107 V at same IPPM; VRWM = 64 V; not AEC-Q101 qualified. | Approved for industrial/commercial use only; lacks automotive qualification and high-temp thermal specs. | Select when cost sensitivity outweighs automotive compliance and 185 °C operation. |
| TPSMD64A | Same VRWM and VCL, but larger SMA package (4.5 mm × 2.7 mm × 2.3 mm); Tj max = 175 °C; AEC-Q101 qualified. | Requires more PCB area and has higher thermal resistance (Rth(j-a) ≈ 100 K/W), limiting high-density layouts. | Choose if legacy SMA footprint compatibility is required and 10 mm² board space is available. |
Compared with SMAJ64A-Q and TPSMD64A, PTVS64VS1UTR-Q uniquely combines AEC-Q101 qualification, 185 °C junction rating, and ultra-low 1 mm profile-making it the only option for space-constrained, high-temperature automotive power nodes where thermal and reliability margins are non-negotiable.

FAQ
What is the maximum clamping voltage for PTVS64VS1UTR-Q under standard test conditions?
The clamping voltage VCL is 103.0 V at IPPM = 3.9 A using the 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and represents the maximum voltage seen by downstream circuitry during a defined surge event.
Does PTVS64VS1UTR-Q support bidirectional transient suppression?
No, PTVS64VS1UTR-Q is a unidirectional TVS diode. Its anode-to-cathode forward conduction path is not rated for surge handling; it functions only in reverse-biased mode to clamp positive transients on a positive rail relative to ground.
How does the 185 °C junction rating impact PCB layout decisions?
The 185 °C Tj rating allows operation in extreme ambient environments, but effective heat dissipation requires direct thermal coupling-such as a ≥1 cm² copper pour connected to the cathode pad-to maintain Rth(j-sp) ≤ 18 K/W and avoid exceeding the limit during repeated surges.
Is PTVS64VS1UTR-Q compatible with lead-free reflow soldering processes?
Yes, the SOD123W package is qualified for lead-free reflow per JEDEC J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with thermal profile matching the footprint in Figure 6 (sod123w_fr) and stencil thickness of 0.1 mm.
