Product details
Overview
PTVS45VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 45 V reverse standoff voltage (VRWM), with clamping voltage VCL = 72.7 V at IPPM = 8.3 A and IRM ≤ 0.001 µA at VRWM. It is AEC-Q101 qualified and used in 12 V/24 V automotive power rail protection.
For engineers reviewing the PTVS45VP1UP-QX datasheet, PTVS45VP1UP-QX pinout, PTVS45VP1UP-QX application, or PTVS45VP1UP-QX equivalent, key selection criteria include its 45 V VRWM rating, 72.7 V clamping performance under 10/1000 µs surge, 1 mm profile for space-constrained PCB layouts, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This unidirectional TVS diode operates as a shunt protector: it remains high-impedance below VRWM = 45 V and avalanches sharply at VBR = 50.0–55.3 V to clamp transients. Its junction-to-solder-point thermal resistance is 12 K/W, enabling effective heat dissipation during repetitive surges.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2 (contact/air), with HBM rating of 8 kV - critical for robustness in automotive infotainment and body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 45 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets system operating margin for 12 V/24 V rails. |
| VBR (min/typ/max) | 50.0 / 52.65 / 55.3 V - breakdown onset range at 1 mA; defines precise clamping initiation threshold. |
| VCL @ IPPM | 72.7 V at 8.3 A - peak clamped voltage during 10/1000 µs surge; determines protected IC's voltage stress limit. |
| PPPM | 600 W - rated peak pulse power per IEC 61643-321; confirms capability to absorb ISO 7637-2 Pulse 1/2a/5a transients. |
| IRM | ≤ 0.001 µA at VRWM - ultra-low leakage ensures minimal standby current drain in always-on vehicle systems. |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount outline with 4 mm lead pitch; enables high-density layout and automated assembly. |
| AEC-Q101 | Qualified - certified for automotive use per stress test standard; supports PPAP documentation and long-term reliability in -55 °C to +150 °C environments. |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 1 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., battery rail); avalanche conduction occurs from cathode to anode during overvoltage. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to GND when clamping, requiring low-inductance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Withstands ISO 7637-2 Pulse 5a (50 V, 100 ms) and similar automotive load-dump events without degradation. |
| 1 mm profile | Enables placement beneath connectors or near ECU edge connectors where vertical clearance is constrained. |
| 0.001 µA reverse leakage | Minimizes quiescent current draw in always-on domains (e.g., CAN wake-up circuits), preserving battery life. |
| 30 kV ESD rating | Eliminates need for additional ESD protection on exposed ports (e.g., LIN bus, sensor inputs) in harsh vehicle environments. |
| AEC-Q101 qualification | Validated for 150 °C junction temperature operation and extended lifetime under thermal cycling, vibration, and humidity. |
Applications
| Automotive Power Rail Protection | Body Control Module (BCM) Input Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller supply lines against load dump and jump-start transients. IC Role / Device Role: Shunt clamping element placed between VBAT and GND, triggered only during overvoltage events. Use Value: Limits voltage to ≤72.7 V during 8.3 A surge, preventing damage to 48 V-tolerant MCUs and PMICs in modern ECUs. |
Use Scenario: Safeguarding BCM input pins connected to door switches, seat sensors, and lighting controls. IC Role / Device Role: Low-leakage transient suppressor mounted directly at connector entry point. Use Value: Blocks 30 kV ESD strikes and 100 V/100 ms pulses while adding <0.001 µA leakage-critical for low-power wake detection. |
| Engine Control Unit (ECU) Sensor Interface | ADAS Camera Power Input Protection |
Use Scenario: Shielding analog sensor signal conditioning circuits (e.g., MAP, TPS) from coupled ignition noise. IC Role / Device Role: Unidirectional TVS placed across sensor supply and ground, filtering fast-rising spikes. Use Value: Clamps sub-µs transients to <72.7 V with <12 K/W thermal resistance, ensuring stable bias for precision ADC front-ends. |
Use Scenario: Securing 5 V or 12 V power input to forward-facing camera modules exposed to ESD and cable discharge. IC Role / Device Role: Primary overvoltage guard before DC-DC converter input stage. Use Value: Maintains 45 V VRWM margin above nominal rail while delivering 600 W surge handling in <1 mm height for compact camera housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ45A-Q | Same VRWM (45 V), but lower PPPM (400 W) and higher VCL (79.4 V at 5.0 A); SOD-123 package (1.6 mm height). | Limited to lower-energy transients; unsuitable for full ISO 7637-2 Pulse 5a compliance. | Select only if board height >1.6 mm is acceptable and surge energy is capped at 400 W. |
| SMCJ45A-Q | Higher PPPM (1500 W), same VRWM, but larger DO-214AB package (2.6 mm height); VCL = 72.7 V at 20.9 A. | Better for high-current load dump, but incompatible with ultra-thin modules due to 2.6× height increase. | Choose when surge current exceeds 8.3 A and PCB space allows larger footprint. |
Compared with SMAJ45A-Q and SMCJ45A-Q, PTVS45VP1UP-QX uniquely balances 600 W surge capacity, 1 mm profile, and AEC-Q101 qualification - making it optimal for next-gen automotive modules where height, reliability, and standardized testing are jointly constrained.

FAQ
What is the maximum clamping voltage of PTVS45VP1UP-QX under standard test conditions?
The clamping voltage VCL is 72.7 V at rated peak pulse current IPPM = 8.3 A, measured per IEC 61643-321 using a 10/1000 µs current waveform at Tj = 25 °C. This value ensures protected downstream ICs see no more than 72.7 V during worst-case surge events.
Is PTVS45VP1UP-QX suitable for bidirectional transient suppression?
No - PTVS45VP1UP-QX is a unidirectional TVS diode, intended for DC circuits with defined polarity (e.g., positive supply to ground). For AC or dual-polarity signal lines, a bidirectional variant like PTVS45VB1UP-QX would be required.
How does the SOD128 package affect thermal performance in high-reliability automotive designs?
The SOD128 package delivers Rth(j-sp) = 12 K/W to the cathode solder point, enabling efficient heat transfer to the PCB copper pour. When mounted on a 1 cm² cathode pad per Nexperia's thermal guidelines, it sustains repeated 600 W surges without exceeding 150 °C junction temperature.
Does PTVS45VP1UP-QX require external series impedance for optimal protection?
Yes - to limit peak current during clamping and prevent excessive power dissipation, a series impedance (e.g., 1–10 Ω resistor or ferrite bead) is recommended between the protected node and the TVS anode. This ensures the device operates within its specified 8.3 A IPPM rating during fast transients.
