Product details
Overview
PTVS64VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection with VRWM = 64 V, VBR(min) = 71.1 V, VCL = 103.0 V at IPPM, and Tj ≤ 185 °C - deployed in industrial power supply rails and automotive under-hood control modules.
For engineers reviewing the PTVS64VS1UTR datasheet, PTVS64VS1UTR pinout, PTVS64VS1UTR application, or PTVS64VS1UTR equivalent, key selection criteria include clamping voltage at rated peak pulse current, junction temperature derating behavior, thermal resistance to solder point, and IEC 61643-321 (10/1000 µs) compliance for surge immunity validation.
Technical Context
This TVS diode operates in avalanche breakdown mode under transient stress, with unidirectional polarity and cathode-anode terminal configuration. Its VBR = 71.1–78.6 V (min–max at 5 mA) ensures precise overvoltage thresholding above 64 V standoff, while low IRM = 0.001 µA at VRWM guarantees minimal leakage in standby.
Thermal design is enabled by Rth(j-sp) = 18 K/W to cathode solder point and stable PPPM = 400 W up to Tj = 150 °C (derated to ~220 W at 185 °C per Fig. 2), supporting operation in ambient temperatures from −55 °C to +185 °C without derating penalties typical of standard TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 64 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 71.1 V at 5 mA - guaranteed avalanche breakdown onset for reliable overvoltage triggering |
| VCL | 103.0 V at IPPM - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W (10/1000 µs waveform) - surge energy handling capacity compliant with IEC 61643-321 |
| Tj max | 185 °C - extended junction temperature rating enables placement near hot components |
| IRM | 0.001 µA at VRWM - ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| Rth(j-sp) | 18 K/W - low thermal resistance to cathode solder point improves power dissipation in compact layouts |
Pinout & Package
The device uses a 2-terminal SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with 0.9–1.1 mm body height and cathode-marked side indicated by a molded bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; carries full surge current during clamping |
| 2 (A) | Anode | Connected to ground or low-impedance return path; completes conduction loop during transient |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation at Tamb = 185 °C and Tj = 185 °C - eliminates need for thermal derating in engine-control or downhole electronics |
| Low-profile packaging | 1.0 mm max height - enables use in space-constrained PCBs where Z-height is critical (e.g., stacked modules) |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >8 kV HBM - provides system-level ESD immunity without additional protection stages |
| Stable clamping performance | VCL variation < ±5 % across −55 °C to +150 °C - ensures predictable protection margin in wide-temperature environments |
Applications
| Industrial Power Supply Protection | Automotive Engine Control Unit (ECU) |
|---|---|
Use Scenario: Protecting 24 V DC input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role: Unidirectional TVS placed between VIN and GND, absorbing 400 W surges while holding clamped voltage below 103 V. Use Value: Prevents damage to upstream DC-DC controllers and downstream microcontrollers during field-installation wiring faults or relay coil de-energization. | Use Scenario: Safeguarding CAN transceiver power pins in under-hood ECUs exposed to ISO 7637-2 Pulse 5a (load dump). IC Role / Device Role: Primary overvoltage clamp on 5 V or 3.3 V regulator input, activated within nanoseconds of voltage excursion beyond 64 V. Use Value: Maintains functional safety integrity by limiting regulator input stress to <103 V, avoiding latch-up or permanent failure during vehicle battery disconnect events. |
| High-Temperature Sensor Interface | Renewable Energy Inverter Control Board |
Use Scenario: Shielding analog front-end inputs of RTD or thermocouple signal conditioners operating near turbine housings or exhaust manifolds. IC Role / Device Role: Low-leakage (0.001 µA) TVS on sensor excitation lines, maintaining accuracy while surviving ambient temps up to 185 °C. Use Value: Eliminates measurement drift caused by thermal-induced leakage current, enabling direct mounting adjacent to heat sources without heatsinking. | Use Scenario: Protecting gate driver supply rails in solar inverter motor control boards subject to grid surge coupling and lightning-induced transients. IC Role / Device Role: High-energy (400 W) clamping device on isolated 15 V bias rails feeding IGBT drivers, rated for continuous 125 °C board temperature. Use Value: Ensures uninterrupted PWM operation during Category III surge events by limiting voltage overshoot to 103 V, preserving driver IC reliability over 20+ year field life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A | Lower PPPM = 400 W but only rated to Tj = 150 °C; VCL = 103 V same; Rth(j-a) = 50 K/W vs. 70 K/W for PTVS64VS1UTR | Not qualified for continuous operation above 150 °C ambient - unsuitable for under-hood or downhole use | Select when cost sensitivity outweighs high-temperature requirement and board layout allows larger thermal pad |
| SMCJ64A | Higher PPPM = 1500 W but SMC package (7.1 mm × 6.2 mm); VCL = 103 V; Tj max = 175 °C; Rth(j-sp) not specified | Larger footprint and higher profile (2.6 mm) limit use in dense, low-Z designs | Choose when surge energy exceeds 400 W and PCB real estate permits larger package |
Compared with SMAJ64A and SMCJ64A, PTVS64VS1UTR uniquely delivers 400 W surge capability in a 1 mm-profile SOD123W package with full 185 °C junction rating - making it the only option for space-constrained, ultra-high-temperature deployments where thermal resistance to solder point (18 K/W) and minimal leakage (0.001 µA) are mandatory.

FAQ
What is the maximum clamping voltage of PTVS64VS1UTR at its rated peak pulse current?
The clamping voltage VCL is 103.0 V at the rated peak pulse current (IPPM) under IEC 61643-321 10/1000 µs waveform conditions. This value is measured at Tj = 25 °C and represents the maximum voltage seen across the device during a 400 W transient event, ensuring downstream components remain within safe operating limits.
Does PTVS64VS1UTR support bidirectional transient suppression?
No, PTVS64VS1UTR is a unidirectional TVS diode configured for protection against positive-going transients only. Its anode-cathode polarity requires connection with cathode to the protected line and anode to ground. For bidirectional protection, two devices in series opposition or a dedicated bidirectional variant would be required.
How does junction temperature affect the 400 W peak pulse power rating?
Per Figure 2 in the datasheet, PPPM remains at 100 % of 400 W up to Tj = 150 °C, then linearly derates to approximately 220 W at Tj = 185 °C. This controlled derating enables predictable surge handling across the full rated junction temperature range without abrupt failure thresholds.
Is PTVS64VS1UTR automotive-qualified?
No - although rated for Tj = 185 °C and used in under-hood ECU designs, PTVS64VS1UTR is not officially AEC-Q200 qualified. It lacks automotive-specific qualification testing (e.g., vibration, humidity, lifetime HTOL). For automotive production, confirm qualification status directly with Nexperia or select an AEC-Q200-compliant variant if mandated by OEM requirements.
