Product details
Overview
PTVS17VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features a 17 V reverse standoff voltage (VRWM), 20.9 V maximum clamping voltage (VCL) at 27.6 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - optimized for compact, high-reliability board-level protection in industrial power supplies.
For engineers reviewing the PTVS17VS1UR,115 datasheet, PTVS17VS1UR,115 pinout, PTVS17VS1UR,115 application, or PTVS17VS1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (Rth(j-sp) = 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 17 V VRWM threshold and clamping transients to ≤20.9 V at 27.6 A. Its junction-to-solder-point thermal resistance of 18 K/W enables effective heat dissipation into PCB copper during repetitive surge events.
The device conforms to IEC 61643-321 (10/1000 µs waveform) and supports ESD immunity up to 30 kV (IEC 61000-4-2 contact discharge). Its 1 mm profile and 2.6 mm × 1.7 mm footprint meet space-constrained SMT requirements without compromising surge handling capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VCL @ IPPM | 20.9 V at 27.6 A - Clamped voltage during 10/1000 µs surge; determines protected circuit's maximum stress level. |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321; defines single-event surge energy handling capacity. |
| IRM | 0.001 µA at VRWM - 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; enables direct PCB copper thermal coupling for sustained surge duty. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides robust system-level ESD immunity without external shielding. |
Pinout & Package
PTVS17VS1UR,115 uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by a bar. Designed for automated placement and reflow soldering with standard footprint per Nexperia doc sod123w_fr.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., VCC rail); polarity-sensitive - reverse connection disables clamping function. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to GND during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without degradation in industrial 24 V systems. |
| 1 mm package height | Enables use in ultra-thin assemblies (e.g., automotive ECUs, portable medical devices) where Z-axis clearance is constrained. |
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision v.4, Dec 2025), supporting deployment in non-safety-critical vehicle subsystems. |
| 0.001 µA IRM | Minimizes quiescent current draw in always-on circuits (e.g., CAN bus nodes, IoT sensor sleep modes). |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 24 V DC input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed at power entry point to clamp surges before they reach DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤20.9 V, preventing damage to downstream 3.3 V/5 V logic while maintaining <0.001 µA leakage during normal operation. |
Use Scenario: Safeguarding LIN bus power lines and sensor supply rails in BCMs exposed to battery transients and ESD. IC Role / Device Role / Timing Role: Board-level surge suppressor mounted adjacent to connector interfaces to absorb fast-rising pulses (≤10 ns rise time) per ISO 10605. Use Value: Delivers 30 kV ESD immunity and clamps 12 V system surges to 20.9 V within 1 ns response time, preserving signal integrity across multiple LIN nodes. |
| Industrial Motor Drive Control | Smart Building HVAC Controller |
Use Scenario: Shielding gate driver IC power pins from flyback spikes generated by MOSFET/IGBT switching in variable-frequency drives. IC Role / Device Role / Timing Role: Localized TVS placed at gate driver VDD pin to suppress sub-microsecond voltage overshoots induced by parasitic inductance. Use Value: Achieves 27.6 A peak pulse current handling with 20.9 V clamping, ensuring gate driver undervoltage lockout (UVLO) thresholds are not exceeded during switching transitions. |
Use Scenario: Protecting 24 V auxiliary power inputs in HVAC zone controllers subjected to lightning-induced surges on long building wiring runs. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power input, coordinated with upstream MOVs to handle multi-staged surge energy distribution. Use Value: Provides 400 W peak power rating and 18 K/W junction-to-solder-point thermal resistance, enabling reliable operation under repeated 10/1000 µs surges without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | DO-214AC package (4.5 mm × 2.7 mm), 400 W PPPM, 27.6 V VCL @ 14.3 A IPPM - higher clamping voltage and larger footprint. | Less suitable for space-constrained designs; lower current density limits effectiveness in high-peak-current scenarios. | Select when legacy DO-214AC footprint compatibility is required and board area is not constrained. |
| SMCJ17A | DO-214AB package (7.1 mm × 6.2 mm), 1500 W PPPM, 27.6 V VCL @ 54.3 A IPPM - significantly higher surge rating but 7× larger volume. | Over-specified for 400 W needs; introduces unnecessary thermal mass and layout complexity in compact systems. | Choose only if system-level testing requires >1000 W surge margin or multi-pulse endurance beyond IEC 61643-321 single-shot compliance. |
Compared with SMAJ17A and SMCJ17A, PTVS17VS1UR,115 delivers identical 400 W surge rating in a 75% smaller footprint and achieves 20.9 V clamping - 6.7 V lower than SMAJ17A - reducing stress on downstream 24 V-rated components without sacrificing reliability or AEC-Q101 qualification.

FAQ
What is the maximum clamping voltage of PTVS17VS1UR,115 under IEC 61643-321 test conditions?
The maximum clamping voltage (VCL) is 20.9 V at 27.6 A peak pulse current (IPPM), measured using the standardized 10/1000 µs current waveform. This value is confirmed in Table 8 of the official Nexperia datasheet (v.4, Dec 2025) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS17VS1UR,115 qualified for automotive applications per AEC-Q101?
Yes - according to the revision history in the December 2025 datasheet (v.4), PTVS17VS1UR,115 is explicitly listed among the 33 types granted AEC-Q101 qualification. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD per the AEC standard for discrete semiconductors.
How does the SOD123W package affect thermal performance compared to larger TVS packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W - significantly lower than typical DO-214AC (SMA) or DO-214AB (SMB) packages - due to its direct cathode tab solder connection and optimized internal die attach. This allows faster heat transfer to PCB copper, improving surge repetition rate capability without derating.
Can PTVS17VS1UR,115 be used in bidirectional configurations?
No - PTVS17VS1UR,115 is a unidirectional TVS diode with anode and cathode terminals. Bidirectional protection requires either two devices in series opposition or a dedicated bidirectional part (e.g., PTVS17VS1UR,115's counterpart PTVS17VS1U,115 is not offered; alternative series like PTVS17VS1U,115 do not exist in this family).
