Product details
Overview
PTVS43VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. Confirmed parameters: VRWM = 43 V, VBR(min) = 47.8 V, VCL = 69.4 V at IPPM = 8.6 A (10/1000 µs), Tj ≤ 185 °C, and AEC-Q101 qualified.
For engineers reviewing the PTVS43VP1UTP-QX datasheet, PTVS43VP1UTP-QX pinout, PTVS43VP1UTP-QX application, or PTVS43VP1UTP-QX equivalent, this page delivers verified electrical specs, thermal behavior at elevated junction temperatures, clamping performance under IEC 61643-321 waveforms, and automotive-grade reliability validation - all critical for 12 V/24 V battery rail surge protection design.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM (43 V), then avalanches sharply at VBR ≥ 47.8 V to clamp transients to ≤69.4 V. Its low IRM ≤ 0.001 µA at VRWM ensures minimal leakage in standby power systems.
Thermal design is enabled by Rth(j-sp) = 12 K/W (to solder point) and rated operation up to Tj = 185 °C, supported by AEC-Q101 qualification for under-hood automotive environments. The 1 mm profile and SOD128 footprint meet space-constrained PCB layouts requiring robust ESD/ISO 7637-2 immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 43 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin for 36 V nominal automotive systems. |
| VBR (min) | 47.8 V - Minimum breakdown voltage at 10 mA; guarantees reliable turn-on during fast-rising transients above system operating voltage. |
| VCL @ IPPM | 69.4 V - Clamping voltage at 8.6 A peak pulse current (10/1000 µs); limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a events. |
| PPPM | 600 W - Peak pulse power rating per IEC 61643-321; enables single-device protection against high-energy load-dump surges. |
| Tj max | 185 °C - Maximum junction temperature; supports placement near heat sources (e.g., engine control units) without derating. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air) - Full-system ESD immunity without external spark gaps or RC filters. |
| Rth(j-sp) | 12 K/W - Thermal resistance from junction to cathode solder point; enables effective heat transfer to PCB copper pour for sustained pulse handling. |
Pinout & Package
SOD128 (CFP5) plastic surface-mount package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat leads with cathode marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs from anode to cathode during overvoltage. |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance shunt path during transient events to divert surge current away from load. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity, and mechanical shock - eliminates need for additional qualification testing. |
| 185 °C junction rating | Enables direct mounting on high-temperature PCB zones (e.g., near power converters) without thermal derating or heatsinks. |
| 600 W peak pulse power | Handles ISO 7637-2 Load Dump (Pulse 5a) energy in 12 V systems without failure or parameter shift. |
| 0.001 µA IRM at VRWM | Minimizes quiescent current drain in always-on vehicle modules (e.g., CAN gateways, body controllers), preserving battery life. |
| 1 mm package height | Supports low-profile designs in compact ECUs and ADAS sensor modules where Z-axis clearance is constrained. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A-Q | Lower PPPM (400 W), higher VCL (72.7 V), same VRWM (43 V), SMA package (higher Rth(j-a) ≈ 50 K/W). | Limited to lower-energy transients; less suitable for load dump in 24 V systems due to reduced power handling. | Select when cost sensitivity outweighs peak surge requirement and board space allows larger SMA footprint. |
| SMCJ43A-Q | Higher PPPM (1500 W), same VRWM (43 V), VCL = 69.4 V, but larger SMC package (7.1 mm × 6.2 mm) and Tj = 175 °C. | Better for extreme surge events but incompatible with space-constrained automotive modules due to 3× footprint area. | Choose only if system-level testing confirms need for >600 W capability and PCB layout accommodates SMC size. |
Compared with SMAJ43A-Q, PTVS43VP1UTP-QX delivers 50% higher surge power in half the footprint and extends junction temperature capability by 10 °C; versus SMCJ43A-Q, it trades absolute peak power for AEC-Q101-compliant miniaturization and superior thermal coupling to PCB copper.

FAQ
What is the maximum clamping voltage of PTVS43VP1UTP-QX under standard test conditions?
The clamping voltage VCL is 69.4 V at IPPM = 8.6 A using the 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and represents the upper bound of voltage seen by protected circuitry during a defined surge event.
Does PTVS43VP1UTP-QX support bidirectional transient suppression?
No - PTVS43VP1UTP-QX is a unidirectional TVS diode. It conducts only when the cathode is positive relative to the anode. For bidirectional protection (e.g., data lines), a separate symmetric device such as PTVS3V3S1UTP-QX would be required.
How does the 185 °C junction rating impact PCB layout decisions?
The 185 °C rating allows direct placement near heat-generating components (e.g., DC-DC converters) without thermal derating, provided the cathode solder pad connects to ≥1 cm² of 1 oz copper for optimal Rth(j-sp) = 12 K/W performance per datasheet condition.
Is PTVS43VP1UTP-QX compatible with lead-free reflow processes?
Yes - the device is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), with peak temperature tolerance up to 260 °C. The CFP5 package uses matte tin-plated leads and meets RoHS and REACH requirements.
