Product details
Overview
PTVS64VS1UR-QX from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) diode in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection at 64 V reverse standoff voltage (VRWM), with clamping voltage VCL = 103.0 V at IPPM = 3.9 A (10/1000 μs waveform), and qualified to AEC-Q101 for under-hood power rail and ECU input protection.
For engineers reviewing the PTVS64VS1UR-QX datasheet, PTVS64VS1UR-QX pinout, PTVS64VS1UR-QX application, or PTVS64VS1UR-QX equivalent, this device is selected for high-energy transient suppression in 12 V/24 V/48 V automotive subsystems where low leakage (IRM ≤ 0.001 μA), compact footprint (2.6 × 1.7 × 1.0 mm), and junction temperature up to 150 °C are critical design constraints.
Technical Context
This unidirectional TVS operates as a clamping device in series with the protected line, conducting only during overvoltage events above its breakdown voltage (VBR = 71.1–78.6 V). Its I-V characteristic follows standard avalanche behavior with sharp knee at IR = 1 mA, enabling precise voltage thresholding without forward conduction during normal operation.
It complies with IEC 61643-321 (10/1000 μs pulse) and supports ESD immunity per IEC 61000-4-2 (±30 kV contact/air) and MIL-STD-883 HBM (8 kV), making it suitable for CAN/LIN bus interfaces and sensor supply rails exposed to load dump and ISO 7637-2 transients.
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/typ/max) | 71.1 / 74.85 / 78.6 V - Breakdown occurs within this range at IR = 1 mA; ensures consistent turn-on across temperature and process variation. |
| VCL @ IPPM | 103.0 V at 3.9 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to <105 V during load dump events. |
| PPPM | 400 W - Peak pulse power handling per IEC 61643-321; sustains single 10/1000 μs surges up to 3.9 A without degradation. |
| IRM | 0.001 μA at VRWM - Ultra-low reverse leakage preserves battery life in always-on automotive modules (e.g., body control units). |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount outline with 1 mm height; enables high-density layout on engine control PCBs. |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications including temperature cycling, HTRB, and ESD. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package with two terminals, 2.6 mm × 1.7 mm × 1.0 mm body dimensions and cathode-marked side (bar marking indicates Pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., battery rail); polarity must match unidirectional clamping direction toward ground. |
| 2 (A) | Anode | Connected to system ground; forms low-impedance path for surge current during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power rating | Enables robust protection against ISO 7637-2 Pulse 5a (load dump) in 24 V systems without derating at Tj = 125 °C. |
| 0.001 μA reverse leakage at VRWM | Minimizes quiescent current drain in always-on vehicle networks (e.g., LIN gateway sleep mode), extending battery hold-up time. |
| 1 mm profile SOD123W package | Reduces board space by >30% vs. SMA packages while maintaining thermal performance via optimized solder pad thermal coupling. |
| AEC-Q101 qualification | Validates reliability for 15-year automotive service life under thermal cycling (-40 °C to +125 °C), humidity, and mechanical shock. |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for additional ESD protection on low-speed signal lines such as sensor inputs or diagnostic ports. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Protects 5 V/12 V microcontroller supply rails from load dump transients during alternator regulation failure. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between battery feed and LDO input, activated within nanoseconds of overvoltage onset. Use Value: Limits voltage to ≤103 V during 100 ms load dump event, preventing LDO destruction and preserving firmware integrity. |
Use Scenario: Shields LIN bus transceiver power pins from coupled transients induced by relay switching in door module actuators. IC Role / Device Role / Timing Role: Standby-mode TVS connected to VCC line of LIN PHY, responding to sub-100 ns spikes from inductive kickback. Use Value: Maintains <1 μA leakage to avoid waking BCM from sleep state while clamping 30 A surges to <110 V. |
| Automotive Camera Power Supply | Electric Power Steering (EPS) Sensor Interface |
|
Use Scenario: Guards 12 V camera module input against jump-start surges and battery reversal during service operations. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail upstream of DC-DC converter, with cathode tied to input. Use Value: Withstands 400 W pulses without parametric shift, ensuring camera remains operational after repeated 24 V jump-start events. |
Use Scenario: Protects analog output of steering angle sensor from ESD and cable discharge events on harness connectors. IC Role / Device Role / Timing Role: Low-capacitance TVS on sensor VSENSE line, placed adjacent to connector to minimize inductance. Use Value: Clamps 8 kV HBM discharges to <105 V within 1 ns, preventing ADC saturation and torque signal corruption. |
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-Q | Lower PPPM (400 W same), but higher VCL = 104 V at 3.5 A; larger SMA package (4.5 × 2.7 × 2.2 mm). | Less suitable for ultra-thin modules due to 2.2 mm height; requires larger PCB area and has higher thermal resistance (Rth(j-a) ≈ 100 K/W). | Select when legacy SMA footprint compatibility is required and board height >2.2 mm is acceptable. |
| TPSMD64AH | Same VRWM and VCL, but rated for 500 W PPPM; larger SMC package (7.1 × 6.2 × 2.6 mm); not AEC-Q101 qualified. | Used in industrial power supplies where automotive qualification is unnecessary and higher surge margin is prioritized over size. | Choose for non-automotive 48 V systems needing extended surge endurance beyond 400 W, accepting larger footprint. |
Compared with SMAJ64A-Q and TPSMD64AH, PTVS64VS1UR-QX delivers identical 64 V clamping performance in a 60% smaller volume and AEC-Q101 compliance-critical for next-gen ADAS domain controllers where board space and automotive qualification are non-negotiable.

FAQ
What is the maximum junction temperature rating for PTVS64VS1UR-QX?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 thermal stress testing. This allows operation in under-hood environments up to 125 °C ambient with appropriate PCB copper pour, supporting use in engine control and transmission modules.
Does PTVS64VS1UR-QX support bidirectional transient suppression?
No-it is a unidirectional TVS diode, configured to clamp only positive transients relative to ground. For bidirectional protection (e.g., data lines), a separate symmetric device like PTVS64VS1UR-Q (dual-diode configuration) or dedicated bidirectional TVS would be required.
How does the 1 mm package height impact thermal performance?
The SOD123W package achieves Rth(j-sp) = 18 K/W to cathode solder point, enabling efficient heat transfer to PCB copper. Its low profile does not compromise thermal capability when using recommended 1 cm² cathode pad per datasheet Figure 4, sustaining 400 W pulses without exceeding Tj limit.
Is PTVS64VS1UR-QX compatible with lead-free reflow processes?
Yes-it is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), with peak temperature tolerance up to 260 °C. The CFP3 package uses matte tin terminations and meets IPC/JEDEC standards for solderability and intermetallic formation control.
