Product details
Overview
PTVS16VS1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features 16 V reverse standoff voltage (VRWM), 26.0 V clamping voltage (VCL) at 5 mA, 15.9 A peak pulse current (IPPM), and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS16VS1UTR,115 datasheet, PTVS16VS1UTR,115 pinout, PTVS16VS1UTR,115 application, or PTVS16VS1UTR,115 equivalent, this device is selected for robust ESD/surge protection in industrial power supplies, automotive body electronics, and high-reliability embedded systems where thermal stability and low-profile mounting are critical.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transients above its VRWM of 16 V. Its VBR min/max of 17.8 V / 19.7 V ensures precise triggering with tight tolerance, while the 0.001 µA IRM at VRWM guarantees minimal leakage in standby.
Thermal design is enabled by Rth(j-sp) = 18 K/W to cathode solder point and rated operation up to Tj = 185 °C - validated per IEC 61643-321 (10/1000 µs waveform) and MIL-STD-883 HBM (>8 kV) and IEC 61000-4-2 contact discharge (30 kV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VCL @ 5 mA | 26.0 V - clamped voltage during 5 mA test current; defines upper rail limit under surge |
| IPPM | 15.9 A - peak pulse current capability under 10/1000 µs waveform at 400 W |
| IRM | 0.001 µA - ultra-low reverse leakage at VRWM, minimizing standby power loss |
| Tj max | 185 °C - enables use in under-hood, motor drive, and industrial control environments |
| Rth(j-sp) | 18 K/W - thermal resistance to cathode solder point supports PCB-level thermal management |
| ESD rating | 30 kV contact discharge (IEC 61000-4-2); >8 kV HBM - exceeds Level 4 immunity requirements |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat lead profile optimized for automated assembly and thermal relief on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line; marking bar identifies this terminal; carries surge current to ground path |
| 2 (A) | Anode | Connected to system ground; completes conduction path during avalanche clamping event |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 185 °C - eliminates derating in hot ambient environments like motor drives and power converters |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained modules and stacked PCB assemblies |
| Precision clamping window | VBR = 17.8–19.7 V with 26.0 V VCL - tight margin between VRWM and VCL improves system-level surge margin |
| Ultra-low leakage | IRM = 0.001 µA - prevents battery drain or signal integrity issues in always-on circuits |
| Robust ESD immunity | 30 kV contact discharge - protects downstream ICs without requiring additional external filtering |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 12 V DC input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp surges within 1 ns response time. Use Value: Prevents damage to upstream DC-DC converters and microcontrollers during field wiring faults or relay coil de-energization. |
Use Scenario: Safeguarding LIN bus power inputs and sensor supply lines in BCMs exposed to automotive battery transients. IC Role / Device Role / Timing Role: Standoff-clamp TVS on 12 V auxiliary rail, activated only when voltage exceeds 16 V threshold. Use Value: Maintains functional safety compliance (ISO 16750-2) without adding series impedance or affecting signal timing. |
| Motor Drive Gate Driver Protection | High-Temperature IoT Sensor Node |
Use Scenario: Shielding isolated gate driver bias supplies in BLDC inverters operating near heat sinks at >125 °C ambient. IC Role / Device Role / Timing Role: TVS mounted directly at driver IC VDD pin to suppress Miller-induced spikes and cross-talk. Use Value: Enables reliable operation at 150 °C ambient with no derating - avoids premature failure in sealed enclosures. |
Use Scenario: Protecting 3.3 V supply rails of wireless temperature sensors deployed in furnace monitoring or oil-well downhole tools. IC Role / Device Role / Timing Role: Low-leakage TVS on regulated output, leveraging 0.001 µA IRM to preserve battery life over 10-year deployments. Use Value: Eliminates need for active supervision circuitry while sustaining >185 °C junction temperature during short thermal excursions. |
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; 400 W PPPM; VRWM = 16 V; VCL = 26.0 V; Tj max = 150 °C | Larger footprint (4.5 mm × 2.7 mm) and 2.3 mm height - unsuitable for ultra-thin modules | Select when board space allows larger package and thermal interface uses heatsink pads instead of solder-point conduction |
| SMCJ16A | DO-214AB package; 1500 W PPPM; VRWM = 16 V; VCL = 30.0 V; Tj max = 175 °C | Higher clamping voltage increases stress on downstream ICs; requires 7.1 mm × 6.2 mm area | Choose only for higher-energy surge events (e.g., ISO 7637-2 Pulse 5a); not recommended for space- or thermally constrained designs |
Compared with SMAJ16A and SMCJ16A, PTVS16VS1UTR,115 delivers identical clamping performance in a 60% smaller footprint and extends operational temperature range by +35 °C - enabling direct integration into next-generation compact, high-temperature power modules without layout redesign.

FAQ
What is the maximum clamping voltage of PTVS16VS1UTR,115 under standard test conditions?
The clamping voltage (VCL) is 26.0 V measured at 5 mA test current per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C) and represents the maximum voltage seen by downstream circuitry during a 10/1000 µs surge event.
Can PTVS16VS1UTR,115 be used in bidirectional protection configurations?
No - it is a unidirectional TVS diode with cathode/anode polarity. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional part such as PTVS16VS1UTR's counterpart in the PTVS16VS1UTR-B series must be selected.
How does the 1 mm package height impact thermal performance in high-power surge events?
The 1 mm SOD123W profile reduces thermal mass but maintains effective heat transfer via the cathode solder pad (Rth(j-sp) = 18 K/W). Layout best practices - including ≥1 cm² copper pour under the cathode - ensure sustained 400 W pulse handling without exceeding 185 °C junction limit.
Is PTVS16VS1UTR,115 qualified for automotive applications per AEC-Q200?
No - this variant is not AEC-Q200 qualified. While it meets 185 °C junction temperature and 30 kV ESD ratings, Nexperia specifies separate automotive-grade versions (e.g., PTVS16VS1UTR-Q) with full AEC-Q200 stress testing, PPAP documentation, and zero-defect manufacturing controls.
