Product details
Overview
PTVS43VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 43 V reverse standoff voltage. It delivers 69.4 A peak pulse current (10/1000 µs), clamps transients to ≤52.8 V at 1 mA IR, and exhibits only 0.001 µA reverse leakage at VRWM - deployed in engine control units and battery management systems.
For engineers reviewing the PTVS43VP1UP-QX datasheet, PTVS43VP1UP-QX pinout, PTVS43VP1UP-QX application, or PTVS43VP1UP-QX equivalent, key selection criteria include clamping voltage (VCL = 69.4 V), thermal resistance (Rth(j-sp) = 12 K/W), AEC-Q101 qualification, and SOD128 footprint compatibility with high-density PCB layouts.
Technical Context
This unidirectional TVS diode operates as a shunt-type transient suppressor: under normal bias it presents high impedance (>1 GΩ at VRWM), then avalanches sharply at VBR = 47.8–52.8 V to divert surge energy away from sensitive downstream circuitry. Its junction-to-solder-point thermal resistance of 12 K/W enables effective heat dissipation during repetitive 600 W pulses.
The device complies with IEC 61643-321 (10/1000 µs waveform) and IEC 61000-4-2 (30 kV contact/air ESD), with breakdown voltage tightly specified (±5% typical) and clamping performance validated across -55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000 µs surges up to this level without degradation |
| Reverse Standoff Voltage | VRWM = 43 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage | VCL = 69.4 V at IPPM = 69.4 A - maximum voltage seen by protected circuit during rated surge |
| Breakdown Voltage | VBR = 47.8–52.8 V at IR = 1 mA - precise avalanche onset range ensuring predictable turn-on |
| Reverse Leakage | IRM = 0.001 µA at VRWM - negligible standby current, critical for low-power automotive modules |
| ESD Rating | 30 kV contact / 30 kV air per IEC 61000-4-2 - exceeds automotive infotainment and sensor interface requirements |
| Junction Temp Limit | Tj(max) = 150 °C - supports under-hood operation in engine control and ADAS subsystems |
Pinout & Package
Package: SOD128 (CFP5) - surface-mount plastic package, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, optimized for automated reflow assembly and space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 43 V supply rail); marking bar identifies this terminal |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity, and mechanical shock per discrete semiconductor standard |
| Low-profile SOD128 | 1.0 mm max height enables placement beneath connectors or near edge-mounted components in compact ECUs |
| 600 W surge rating | Handles ISO 7637-2 Pulse 1/2a/5a transients common in 12 V/24 V vehicle electrical systems |
| 0.001 µA IR at VRWM | Minimizes quiescent power loss in always-on battery monitoring circuits and CAN node power rails |
| 12 K/W Rth(j-sp) | Enables direct thermal coupling to copper pour or solder pad, reducing junction temperature rise during repeated surges |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Battery Management System (BMS) |
|---|---|
Use Scenario: Protects microcontroller power rail against load dump transients (ISO 7637-2 Pulse 5a) during alternator regulation failure. IC Role / Device Role / Timing Role: Shunt clamping element placed between 43 V nominal battery feed and LDO input. Use Value: Clamps to 69.4 V within nanoseconds, preventing >50 V stress on 5 V LDO and MCU VDD pins. |
Use Scenario: Shields cell monitor ICs and coulomb counter inputs from jump-start voltage spikes and relay switching noise. IC Role / Device Role / Timing Role: Unidirectional transient suppressor on 43 V auxiliary supply feeding analog front-end circuitry. Use Value: 0.001 µA leakage avoids measurement drift in µA-range current sensing paths. |
| ADAS Camera Module Power Line | Infotainment Head Unit USB-C VBUS Protection |
Use Scenario: Guards image sensor and SerDes power inputs against ESD and cable discharge events in rear-view camera harnesses. IC Role / Device Role / Timing Role: Primary ESD clamp on 43 V camera heater or LED driver supply line. Use Value: 30 kV IEC 61000-4-2 rating ensures robustness against human-body-model discharges during service access. |
Use Scenario: Safeguards USB-C PD controller and power switch from hot-plug transients and reverse polarity faults. IC Role / Device Role / Timing Role: Secondary overvoltage clamp on 43 V backup power rail feeding USB-C port logic. Use Value: Tight VBR tolerance (47.8–52.8 V) prevents false triggering while maintaining margin below 56 V PD sink limit. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A-Q | Lower PPPM (400 W), higher VCL (72.7 V), SMA package (4.5 mm height) | Limited to lower-energy transients; less suitable for load dump in 24 V systems | Select when board height >1 mm is acceptable and surge energy is <400 W |
| TPSMD43C | Same 600 W rating but bidirectional; higher IR (1 µA) and larger DO-214AB package | Supports AC-coupled lines but adds unnecessary capacitance for DC-only 43 V rails | Prefer only if bipolar protection (e.g., LIN bus) is required alongside 43 V DC rail |
Compared with SMAJ43A-Q and TPSMD43C, PTVS43VP1UP-QX offers superior surge handling in minimal height, lower leakage for precision analog rails, and AEC-Q101 validation specific to SOD128 mounting - making it optimal for next-gen compact automotive modules where thermal and spatial constraints dominate.

FAQ
What is the maximum clamping voltage of PTVS43VP1UP-QX at its rated peak pulse current?
The clamping voltage VCL is 69.4 V at IPPM = 69.4 A (10/1000 µs waveform), measured per IEC 61643-321. This value represents the upper bound voltage imposed on the protected line during full-rated surge conditions and is confirmed in Table 8 of the official Nexperia datasheet.
Is PTVS43VP1UP-QX suitable for bidirectional signal line protection?
No - PTVS43VP1UP-QX is a unidirectional TVS diode, intended only for DC power rail protection where polarity is fixed. For bidirectional data lines (e.g., CAN, LIN), a bidirectional variant such as PTVS43VB1UP-QX would be required; this part lacks symmetrical breakdown behavior.
How does the SOD128 package affect thermal performance compared to SMA or SMB?
The SOD128 package achieves Rth(j-sp) = 12 K/W due to its exposed cathode tab and optimized solder pad layout, outperforming SMA (Rth(j-a) ≈ 50 K/W) and SMB (Rth(j-a) ≈ 35 K/W) in junction-to-PCB thermal transfer - critical for sustained surge duty cycles in confined ECU enclosures.
Does PTVS43VP1UP-QX require derating at elevated ambient temperatures?
Yes - Figure 2 shows PPPM decreases to ~50% of rated 600 W at Tj = 125 °C. Designers must apply thermal modeling using Rth(j-a) = 200 K/W (FR4, single-sided) or Rth(j-sp) = 12 K/W (cathode pad) to ensure junction temperature remains ≤150 °C under worst-case surge repetition and ambient conditions.
