Product details
Overview
PTVS16VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection in automotive power rails. It features VRWM = 16 V, VBR(min) = 17.8 V, VCL = 26.0 V at IPPM = 23.1 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS16VP1UTP-QX datasheet, PTVS16VP1UTP-QX pinout, PTVS16VP1UTP-QX application, or PTVS16VP1UTP-QX equivalent, this device is selected for robust clamping in 12 V–24 V automotive subsystems where thermal stability, low leakage (<0.001 µA), and AEC-Q101 qualification are mandatory.
Technical Context
This unidirectional TVS diode uses a planar silicon junction optimized for fast response (<1 ns) to transient surges per IEC 61643-321 (10/1000 µs waveform). Its clamping behavior is defined by a well-controlled breakdown voltage window (17.8–19.7 V) and low dynamic impedance under surge conditions.
Thermal design is enabled by Rth(j-sp) = 12 K/W to cathode solder point and Rth(j-a) = 60 K/W on ceramic PCB - supporting sustained operation at ambient temperatures up to +185 °C when properly mounted with adequate copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (IEC 61643-321, 10/1000 µs); sustains repeated transients in engine control or infotainment power domains |
| Reverse Standoff Voltage | VRWM = 16 V; maximum continuous DC voltage before significant leakage begins - matches 12 V nominal automotive systems with margin |
| Breakdown Voltage | VBR = 17.8–19.7 V (min–max at IR = 1 mA); ensures reliable triggering above normal operating rail |
| Clamping Voltage | VCL = 26.0 V at IPPM = 23.1 A; limits downstream IC stress during ISO 7637-2 pulse 1/2a/5a events |
| Leakage Current | IRM ≤ 0.001 µA at VRWM; negligible standby power loss in always-on vehicle modules |
| Junction Temperature | Tj(max) = 185 °C; enables placement near hot components (e.g., power converters, ECUs) without derating |
| AEC-Q101 Qualified | Stress-tested per Automotive Electronics Council standard; validated for mission-critical automotive use |
Pinout & Package
Package: CFP5 (SOD128) - surface-mounted, 2-terminal plastic package; dimensions 3.8 mm × 2.6 mm × 1.0 mm; marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit's positive rail; absorbs surge current into ground path via anode |
| 2 | Anode (A) | Connected to system ground; completes conduction path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Operation | Tj ≤ 185 °C enables direct placement on high-power boards without thermal derating |
| Low Profile Height | 1.0 mm max height supports ultra-thin module designs and automated optical inspection |
| ESD Robustness | ±30 kV contact/air discharge (IEC 61000-4-2); protects against handling and system-level ESD |
| Automotive Qualification | AEC-Q101 qualified - meets reliability requirements for engine control, ADAS, and body electronics |
| Low Capacitance | ~100 pF at VR = 0 V (typical for 16 V variant); avoids signal integrity impact on medium-speed buses |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-Q | Lower PPPM = 400 W; VRWM = 16 V; VCL = 26.0 V; Tj(max) = 150 °C; not AEC-Q101 qualified | Approved for industrial, not automotive, environments; unsuitable for under-hood deployment | Select only for cost-sensitive non-automotive designs where thermal margin >35 °C is available |
| TPSMD16H | Same PPPM = 600 W and VRWM = 16 V; VCL = 27.5 V; Tj(max) = 175 °C; AEC-Q101 qualified; larger SMA package (4.5 mm × 3.9 mm) | Requires more PCB area; higher Rth(j-a) = 85 K/W limits high-density thermal layout | Choose when legacy SMA footprint compatibility is required and board space permits |
Compared with SMAJ16A-Q and TPSMD16H, PTVS16VP1UTP-QX delivers superior thermal resilience (185 °C vs. 150/175 °C), smallest footprint (SOD128), and lowest profile - making it optimal for next-gen compact, high-temperature automotive modules.

FAQ
What is the maximum clamping voltage for PTVS16VP1UTP-QX under rated surge conditions?
The clamping voltage VCL is 26.0 V at IPPM = 23.1 A using the standardized 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and represents the peak voltage seen by downstream circuitry during worst-case surge events - critical for ensuring compatibility with 28 V tolerant interfaces.
Does PTVS16VP1UTP-QX support bidirectional transient suppression?
No - PTVS16VP1UTP-QX is a unidirectional TVS diode, configured with cathode (pin 1) and anode (pin 2) terminals. It conducts only when the cathode is driven positive relative to the anode. For bidirectional protection, two devices in series opposition or a dedicated bidirectional part like PTVS16VB1UTP-QX would be required.
How does the 185 °C junction rating translate to real-world PCB layout?
The 185 °C rating allows operation at ambient temperatures up to 155 °C when mounted on a 1 cm² cathode pad (Rth(j-sp) = 12 K/W). Designers must use ≥1 mm² thermal pad area, avoid enclosed cavities, and ensure airflow or adjacent heat sinking to maintain Tj ≤ 185 °C during sustained 600 W pulse duty cycles.
Is the SOD128 package compatible with standard reflow profiles?
Yes - the CFP5 (SOD128) package is qualified for lead-free reflow per J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. The footprint in Figure 7 (sod128_fr) specifies 2.5 mm × 3.4 mm solder lands and 1.9 mm × 2.1 mm paste apertures for optimal wetting and void control.
