Product details
Overview
PTVS16VS1UR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) diode in SOD123W (CFP3) package, designed for automotive-grade overvoltage clamping on 16 V DC power rails. It features VRWM = 16 V, VBR(min) = 17.8 V, VCL(max) = 26.0 V at IPPM = 15.4 A (10/1000 µs), and IRM ≤ 0.1 µA, qualified to AEC-Q101 for under-hood ECU protection.
For engineers reviewing the PTVS16VS1UR-Q datasheet, PTVS16VS1UR-Q pinout, PTVS16VS1UR-Q application, or PTVS16VS1UR-Q equivalent, this device is selected for robust 16 V rail transient suppression where low clamping voltage, sub-1 mm profile, and automotive qualification are mandatory design requirements.
Technical Context
This unidirectional TVS operates as a clamping diode with avalanche breakdown behavior, triggered when reverse voltage exceeds VRWM = 16 V. Its junction structure delivers fast response (<1 ns) to transients per IEC 61643-321 (10/1000 µs waveform), with thermal resistance Rth(j-sp) = 18 K/W enabling reliable power dissipation during surge events.
The device uses a planar silicon junction optimized for stable breakdown voltage tolerance (±5% typical), low leakage (≤0.1 µA at VRWM), and high ESD immunity (30 kV contact/air per IEC 61000-4-2). Its cathode-marked SOD123W package supports automated placement and reflow soldering on compact PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; sets threshold for 16 V nominal supply protection. |
| VBR (min) | 17.8 V - Minimum breakdown voltage at 1 mA test current; ensures reliable turn-on above system operating voltage. |
| VCL (max) | 26.0 V - Maximum clamped voltage at 15.4 A peak pulse current; limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a events. |
| PPPM | 400 W - Peak pulse power rating (10/1000 µs); sustains 400 W surge energy without failure under standard automotive test conditions. |
| IRM | 0.1 µA - Max reverse leakage at VRWM; minimizes standby power loss in battery-critical automotive modules. |
| ESD Rating | 30 kV (IEC 61000-4-2 contact/air) - Enables direct interface with exposed connectors without external ESD staging. |
| AEC-Q101 Qualified | Yes - Validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and temperature cycling; suitable for engine control units. |
Pinout & Package
PTVS16VS1UR-Q uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 16 V rail); marking bar identifies this terminal; carries full surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path; must be routed with low-inductance ground plane for effective transient shunting. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 compliant - Meets stress test requirements for under-hood temperature, humidity, and mechanical reliability. |
| Low-profile packaging | 1.0 mm max height - Enables use in space-constrained modules such as ADAS camera ECUs and body control units. |
| High ESD immunity | 30 kV contact/air discharge - Eliminates need for additional ESD protection stages on CAN/LIN bus lines or sensor inputs. |
| Stable clamping performance | VCL variation < ±5% across -55 °C to 150 °C - Ensures consistent protection margin over full automotive temperature range. |
| Low thermal resistance | Rth(j-sp) = 18 K/W - Enables efficient heat transfer from junction to solder point, supporting repeated surge endurance. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus Line |
|---|---|
|
Use Scenario: Protects 16 V battery-fed microcontroller power input against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between VCC and GND, activated within nanoseconds of overvoltage onset. Use Value: Limits voltage to ≤26.0 V during 400 W surges, preventing brownout or latch-up in 32-bit MCUs like Infineon AURIX™. |
Use Scenario: Shields LIN transceiver PHY pins from ESD and cable-induced transients in door module wiring harnesses. IC Role / Device Role / Timing Role: Low-leakage (0.1 µA) TVS connected anode-to-ground, cathode-to-LIN bus, preserving signal integrity at 19.2 kbps. Use Value: Withstands 30 kV ESD strikes while adding <0.1 pF capacitance, avoiding LIN timing skew or false dominant detection. |
| Automotive Camera Power Rail | Electric Power Steering (EPS) Sensor Interface |
|
Use Scenario: Guards image sensor and ISP power supply in rear-view cameras exposed to ignition noise and hot-swap events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 16 V bias rail, mounted adjacent to power converter output capacitor. Use Value: 1 mm height allows placement under compact lens housing; 400 W rating handles ISO 7637-2 Pulse 5a (100 V/100 ms) without derating. |
Use Scenario: Protects Hall-effect position sensor analog outputs from inductive kickback in EPS motor drive circuits. IC Role / Device Role / Timing Role: Reverse-biased TVS on sensor VOUT line, referenced to chassis ground, suppressing >100 V spikes. Use Value: VBR(min) = 17.8 V ensures no conduction during normal 0–5 V analog output swing; clamps only during fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | DO-214AC package (2.8 mm height), PPPM = 400 W, VCL = 27.7 V at 14.4 A | Larger footprint and height; less suitable for ultra-thin modules | Select when board space permits larger package and higher VCL margin is acceptable |
| TPSMD16 | SMD package (SMA), VRWM = 16 V, VCL = 26.5 V at 15.2 A, AEC-Q101 qualified | Higher thermal resistance (Rth(j-a) ≈ 50 K/W vs. 18 K/W), lower surge repetition capability | Prefer for cost-sensitive non-critical systems where solder-point thermal performance is secondary |
Compared with SMAJ16A and TPSMD16, PTVS16VS1UR-Q offers superior thermal performance via its 18 K/W junction-to-solder-point resistance and 1 mm profile-critical for high-density automotive modules requiring repeated surge endurance and minimal Z-height.

FAQ
What is the maximum clamping voltage of PTVS16VS1UR-Q at rated surge current?
The maximum clamping voltage (VCL) is 26.0 V at IPPM = 15.4 A under 10/1000 µs waveform conditions. This value is measured per IEC 61643-321 and guarantees that downstream components see no more than 26.0 V during standardized surge events, making it suitable for protecting 3.3 V and 5 V logic powered from regulated 16 V rails.
How does the SOD123W package affect thermal performance compared to DO-214AC?
The SOD123W package delivers Rth(j-sp) = 18 K/W - significantly lower than DO-214AC's typical ~45 K/W - due to its optimized cathode tab geometry and direct solder-point thermal path. This enables faster heat extraction during repetitive surges, improving reliability in cyclic automotive environments like start-stop systems.
Is PTVS16VS1UR-Q suitable for bidirectional transient protection?
No. PTVS16VS1UR-Q is strictly unidirectional: it clamps only in reverse bias (cathode positive relative to anode). For bidirectional protection (e.g., data lines), a symmetric TVS like PTVS16VS1UR-Q's dual-diode counterpart or a dedicated bidirectional variant must be used; this part will not conduct or clamp during positive-going transients on the anode.
What is the significance of the 'Q' suffix in the part number?
Per Nexperia documentation, the 'Q' suffix denotes AEC-Q101 qualification - confirming full compliance with the Automotive Electronics Council's stress test standard for discrete semiconductors. This includes HTGB, HTRB, ESD, and temperature cycling validation, certifying suitability for automotive powertrain and chassis applications.
