Product details
Overview
PTVS16VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) surface-mount package, designed for clamping transient overvoltages on DC power rails. It features 16 V reverse standoff voltage (VRWM), 19.7 V maximum clamping voltage (VCL) at 26.0 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - optimized for industrial power supply protection with 1 mm profile.
For engineers reviewing the PTVS16VS1UR,115 datasheet, PTVS16VS1UR,115 pinout, PTVS16VS1UR,115 application, or PTVS16VS1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (18 K/W), AEC-Q101 qualification status per revision history, and compatibility with standard SOD123W reflow footprints.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggering when reverse voltage exceeds its 16 V standoff threshold and clamping transients to ≤19.7 V at 26.0 A. Its breakdown voltage is specified at 17.8–19.7 V (min–max) with 1 mA test current, ensuring predictable turn-on behavior across temperature.
Thermal design is supported by low junction-to-solder-point resistance (18 K/W) and rated junction temperature up to 150 °C. The device meets IEC 61000-4-2 ESD immunity (30 kV contact discharge) and withstands non-repetitive forward surge currents up to 50 A (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VCL @ IPPM | 19.7 V at 26.0 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321, enabling robust surge suppression |
| IRM | 0.001 µA - ultra-low reverse leakage ensures minimal standby power loss in battery-backed systems |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point, critical for PCB copper pad layout |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - protects against human-body ESD events without external circuitry |
Pinout & Package
PTVS16VS1UR,115 uses the SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by bar. Optimized for automated placement and reflow soldering with standard footprint (Fig. 6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance shunt path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 surges (2 kV/12 Ω) on 12–24 V systems |
| 1 mm package height | Allows use in space-constrained industrial controllers and automotive ECUs where Z-height is limited |
| AEC-Q101 qualified (per revision v.4) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| Low Rth(j-sp) = 18 K/W | Permits sustained surge handling without thermal runaway when mounted on ≥1 cm² cathode copper pad |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Protecting 12 V input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between input rail and chassis ground, responding within nanoseconds to overvoltage events. Use Value: Limits rail voltage to ≤19.7 V during 26 A surges, preventing damage to upstream DC-DC converters and microcontrollers. |
Use Scenario: Safeguarding LIN bus power inputs in door module ECUs exposed to battery disconnect transients. IC Role / Device Role / Timing Role: Standoff-rated TVS connected directly at connector entry point, absorbing energy before it reaches CAN/LIN transceivers. Use Value: Maintains system uptime by surviving 400 W pulses while adding <0.001 µA leakage to always-on circuits. |
| Smart Meter Power Input Stage | Factory Automation I/O Module |
|
Use Scenario: Shielding metering IC power supplies from grid-induced surges during lightning events on AC mains-derived 12 V rails. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC bus, coordinated with fuse and MOV for staged protection. Use Value: Achieves >100,000 surge cycles at rated PPPM due to stable silicon avalanche characteristics and low thermal resistance. |
Use Scenario: Protecting isolated 24 V digital input channels from field-wiring induced transients in PLC backplanes. IC Role / Device Role / Timing Role: Localized TVS at each channel's power entry, minimizing trace inductance for fastest clamping response. Use Value: 1 mm height enables dense channel packing without compromising creepage/clearance or mechanical clearance. |
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 | DO-214AC package (4.5 mm height), 400 W rating, 17.8 V VRWM, 26.0 V VCL @ 15.3 A | Higher clamping voltage and larger footprint; less suitable for ultra-low-profile designs | Choose when board space allows taller components and higher VCL is acceptable for legacy layout reuse |
| SMCJ16A | DO-214AB package (2.6 mm height), 1500 W rating, 16 V VRWM, 25.0 V VCL @ 60.0 A | Triple power rating but 2.5× larger footprint and 2.6× greater height than SOD123W | Prefer for high-energy surge environments (e.g., outdoor telecom) where PCB area is not constrained |
Compared with SMAJ16A and SMCJ16A, PTVS16VS1UR,115 delivers identical 16 V standoff and 400 W capability in a 1 mm profile - making it optimal for next-gen industrial and automotive modules where Z-height and thermal coupling to PCB are critical constraints.

FAQ
Is PTVS16VS1UR,115 qualified for automotive applications?
Yes - per revision v.4 of the datasheet (issued 1 December 2025), PTVS16VS1UR,115 is explicitly listed among the 33 types granted AEC-Q101 qualification. This includes full stress testing per the Automotive Electronics Council standard for discrete semiconductors, covering temperature cycling, high-temperature reverse bias, and ESD robustness.
What is the maximum clamping voltage under a 10/1000 µs surge?
At 26.0 A peak pulse current (IPPM), the maximum clamping voltage (VCL) is 19.7 V - measured per IEC 61643-321 using the standardized 10/1000 µs current waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
How does the SOD123W package affect thermal performance?
The SOD123W package achieves Rth(j-sp) = 18 K/W (junction-to-solder-point) when the cathode is soldered to a ≥1 cm² copper pad on FR4. This low thermal resistance enables efficient heat transfer from the silicon die into the PCB, allowing repeated 400 W pulse handling without exceeding the 150 °C maximum junction temperature.
Can PTVS16VS1UR,115 replace older PTVS16VS1U parts?
No - PTVS16VS1UR,115 supersedes earlier versions with updated qualification status and tightened parametric limits. The "R" suffix denotes the revised series with AEC-Q101 compliance confirmed in v.4; legacy PTVS16VS1U parts lack this validated automotive qualification and may exhibit wider VBR tolerances or higher IRM.
