Product details
Overview
PTVS16VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 16 V reverse standoff voltage (VRWM), with clamping voltage VCL = 26.0 V at IPPM = 23.1 A (10/1000 µs), and qualified to AEC-Q101. It protects power rails in engine control units, body electronics, and infotainment power supplies.
For engineers reviewing the PTVS16VP1UP-QX datasheet, PTVS16VP1UP-QX pinout, PTVS16VP1UP-QX application, or PTVS16VP1UP-QX equivalent, key selection criteria include VRWM = 16 V, VCL = 26.0 V @ 23.1 A, Rth(j-sp) = 12 K/W, IRM ≤ 0.001 µA, and AEC-Q101 qualification for under-hood automotive deployment.
Technical Context
This unidirectional TVS diode operates as a clamping device: it remains high-impedance below VRWM = 16 V, then avalanches sharply at VBR = 17.8–19.7 V (min–max) to limit transient energy. Its low-profile SOD128 package enables placement near IC power pins with minimal PCB area.
It complies with IEC 61643-321 (10/1000 µs waveform) and withstands ±30 kV ESD (IEC 61000-4-2 contact/air), supporting robust front-end protection in 12 V automotive systems where load dump and ISO 7637-2 pulses demand fast response and high PPPM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - Maximum continuous reverse operating voltage before leakage exceeds 0.1 µA; sets system rail compatibility for 12 V nominal automotive circuits. |
| VBR (min–max) | 17.8–19.7 V - Breakdown voltage range at IR = 1 mA; defines precise clamping onset tolerance for predictable surge suppression timing. |
| VCL @ IPPM | 26.0 V @ 23.1 A - Clamped voltage during 10/1000 µs surge; ensures downstream ICs (e.g., MCU, CAN transceiver) see <26 V during worst-case transients. |
| PPPM | 600 W - Peak pulse power rating per IEC 61643-321; supports single-event energy absorption up to 600 W without failure. |
| IRM | ≤0.001 µA - Reverse leakage at VRWM; guarantees negligible standby current drain in always-on vehicle modules. |
| Rth(j-sp) | 12 K/W - Junction-to-solder-point thermal resistance; enables effective heat transfer to PCB copper, critical for sustained surge duty cycles. |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications; validated for temperature cycling, HBM ESD, and humidity testing. |
Pinout & Package
PTVS16VP1UP-QX uses the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for reflow soldering and space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; marking bar on package identifies this terminal; carries surge current into ground path during clamping. |
| 2 (A) | Anode | Connected to system ground; completes conduction path during avalanche; low-inductance layout minimizes VCL overshoot during fast transients. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables single-device protection against ISO 7637-2 Pulse 5a (load dump) surges in 12 V systems without cascaded TVS stages. |
| 1 mm package height | Allows placement beneath connectors or under shields in compact ECUs, reducing board stack height and improving mechanical robustness. |
| ±30 kV ESD rating | Eliminates need for additional ESD protection on low-speed lines (e.g., LIN, sensor inputs) sharing the same power domain. |
| AEC-Q101 qualification | Confirms reliability across -55 °C to +150 °C ambient, including temperature cycling and mechanical shock, required for engine bay deployment. |
| 0.001 µA reverse leakage | Prevents measurable battery drain in always-on modules (e.g., gateway, telematics), extending parked vehicle battery life. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Protects 12 V supply rail of diesel/gasoline ECU against load dump transients (up to 60 V, 400 ms) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed directly at ECU input connector, responding within nanoseconds to suppress >16 V excursions. Use Value: Limits voltage seen by downstream DC-DC converters and microcontrollers to ≤26.0 V, preventing latch-up or permanent damage during cold-crank or jump-start events. |
Use Scenario: Shields BCM power input from battery line transients caused by relay switching, motor actuation, and ignition noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on fused 12 V feed, positioned before main power distribution ICs and CAN/LIN interface regulators. Use Value: Maintains stable 5 V/3.3 V rail generation by preventing upstream rail collapse or regulator shutdown during 100 A surge events. |
| Infotainment System Power Supply | Advanced Driver Assistance Systems (ADAS) Camera Module |
|
Use Scenario: Guards head unit or display module power input against jump-start spikes and hot-swap transients during service. IC Role / Device Role / Timing Role: First-line transient suppressor on main 12 V input, preceding EMI filters and buck converters feeding SoC and audio amplifiers. Use Value: Ensures uninterrupted operation during transient events by clamping to 26.0 V-below absolute maximum ratings of PMICs and display drivers. |
Use Scenario: Protects camera module's 12 V input from ESD and cable discharge events during installation or vibration-induced contact. IC Role / Device Role / Timing Role: Localized TVS at camera flex cable entry point, minimizing trace inductance to achieve sub-10 ns response time. Use Value: Prevents pixel corruption or sensor reset by limiting transient-induced voltage overshoot on image sensor and serializer power domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VRWM (16 V) but lower PPPM (400 W); higher VCL = 27.7 V @ 14.4 A; DO-214AC package (higher profile, 2.3 mm height). | Limited to non-load-dump scenarios (e.g., ESD-only zones); unsuitable for under-hood locations requiring AEC-Q101. | Select only for cost-sensitive, non-automotive industrial designs where 600 W margin is unnecessary. |
| TPSMD16CA | Bidirectional configuration; identical VRWM (16 V) and PPPM (600 W); larger SMB package (4.6 × 3.6 mm); VCL = 26.5 V @ 22.7 A. | Supports AC-coupled or dual-polarity signals (e.g., CAN bus), but adds unnecessary capacitance and footprint for DC power rail use. | Choose only when bidirectional protection is explicitly required; otherwise, PTVS16VP1UP-QX offers superior size and unidirectional efficiency. |
Compared with SMAJ16A and TPSMD16CA, PTVS16VP1UP-QX delivers AEC-Q101 qualification, 1 mm height, and optimized unidirectional clamping for 12 V automotive power rails-making it the preferred choice for space-constrained, high-reliability ECU and BCM deployments.

FAQ
What is the maximum clamping voltage of PTVS16VP1UP-QX under standard test conditions?
The maximum clamping voltage (VCL) is 26.0 V at rated peak pulse current (IPPM) of 23.1 A, measured using the 10/1000 µs current waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and represents the upper bound of voltage seen by protected circuitry during surge events.
Does PTVS16VP1UP-QX support reflow soldering, and what is its recommended footprint?
Yes, PTVS16VP1UP-QX is qualified for lead-free reflow soldering. The recommended reflow footprint is defined in Nexperia's SOD128 outline (Fig. 7): 2.5 mm × 3.4 mm solder land area with 1.9 mm × 2.1 mm solder paste stencil openings, matching the CFP5 package's 3.8 mm × 2.6 mm body and 4 mm lead pitch.
How does the 1 mm package height impact thermal performance in high-power surge events?
The 1 mm height reduces thermal mass and shortens the thermal path from junction to solder point (Rth(j-sp) = 12 K/W), enabling faster heat dissipation into the PCB copper. This allows the device to sustain repeated 600 W pulses without exceeding 150 °C junction temperature-critical for automotive load dump immunity.
Is PTVS16VP1UP-QX suitable for protecting CAN or LIN bus lines?
No-PTVS16VP1UP-QX is a unidirectional TVS intended for DC power rail protection (e.g., 12 V supply), not data lines. For CAN/LIN, bidirectional TVS devices with lower capacitance (<100 pF) and lower VBR (e.g., PESD5V0S1BA) are required to avoid signal integrity degradation and meet ISO 11898-2/ISO 17987-2 requirements.
