Product details
Overview
PTVS13VS1UR,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 13 V reverse standoff voltage (VRWM), 21.5 V maximum clamping voltage (VCL) at 18.6 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - optimized for compact, high-reliability protection in industrial power management circuits.
For engineers reviewing the PTVS13VS1UR,115 datasheet, PTVS13VS1UR,115 pinout, PTVS13VS1UR,115 application, or PTVS13VS1UR,115 equivalent, this device serves as a surface-mount overvoltage clamp with verified AEC-Q101 qualification status per revision v.4 (2025), low 1 mm profile, and IEC 61643-321 (10/1000 µs) compliance - critical for robustness validation in board-level ESD and surge design.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggered when reverse voltage exceeds VRWM = 13 V, entering breakdown to clamp transients within 1 ns. Its VBR min = 14.4 V and VCL max = 21.5 V define the safe operating window under 10/1000 µs surge conditions.
Thermal performance is defined by Rth(j-a) = 220 K/W (FR4, single-sided copper) and Rth(j-sp) = 18 K/W (cathode solder point), enabling reliable power dissipation up to 400 W peak pulse without thermal runaway at Tj ≤ 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13 V - maximum continuous reverse operating voltage before clamping begins |
| VCL @ IPPM | 21.5 V at 18.6 A - clamped voltage during full-rated 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321, defining surge energy absorption capability |
| IRM | 0.001 µA - ultra-low reverse leakage at VRWM, minimizing standby power loss in battery-sensitive systems |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount footprint with cathode-marked anode-cathode polarity |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - enables direct interface protection without external shielding |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, 1 mm height, cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); absorbs surge current into ground path via series impedance |
| 2 | Anode (A) | Connected to system ground; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision v.4, Dec 2025), supporting extended temperature operation from −55 °C to +150 °C |
| Low-profile SMD package | 1 mm max height enables use in space-constrained PCB layouts, including portable industrial controllers and sensor modules |
| High ESD immunity | 30 kV contact discharge rating eliminates need for supplemental ESD protection in front-end interfaces |
| Stable clamping performance | VCL variation < ±5 % across −40 °C to +125 °C ensures consistent protection margin in wide-temperature environments |
Applications
| Industrial Power Supply Protection | Programmable Logic Controller (PLC) I/O Modules |
|---|---|

IC Role / Device Role / Timing Role: Rail-to-ground clamping element on each 24 V input channel, leveraging low IRM to avoid signal loading. Use Value: Maintains signal integrity with <0.001 µA leakage while suppressing >1 kV fast transients per IEC 61000-4-4. |
| Smart Sensor Node Power Input | Motor Drive Control Board Protection |
Use Scenario: Securing 12 V auxiliary supply lines feeding MEMS sensors and wireless transceivers in predictive maintenance edge devices. IC Role / Device Role / Timing Role: Primary overvoltage clamp on sensor node power entry, coordinated with ceramic bypass capacitors. Use Value: Enables compact 2.6 × 1.7 mm layout with 1 mm height, preserving board real estate for RF antenna clearance. |
Use Scenario: Protecting gate driver IC supply rails in 24 V brushless DC motor controllers subjected to PWM-induced ringing. IC Role / Device Role / Timing Role: Fast-response clamp on 12 V logic supply, placed adjacent to gate driver IC to minimize loop inductance. Use Value: Clamps 10/1000 µs surges to 21.5 V before gate driver undervoltage lockout triggers, avoiding false shutdowns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC package (4.5 × 2.7 mm), 400 W PPPM, VCL = 21.2 V @ 18.9 A, VRWM = 13 V | Larger footprint and 2.2 mm height limit use in ultra-thin designs | Select when higher thermal mass is needed or legacy DO-214AC layout exists |
| 1.5SMC13A | DO-214AB package (7.1 × 6.2 mm), 1500 W PPPM, VCL = 21.2 V @ 71.2 A, VRWM = 13 V | Three-times higher surge rating but incompatible with space-constrained SMT layouts | Choose only for high-energy industrial surge environments where PCB area permits |
Compared with SMAJ13A and 1.5SMC13A, PTVS13VS1UR,115 delivers identical clamping performance in a 65 % smaller footprint and 55 % lower profile - making it optimal for modern miniaturized industrial electronics where board space and height are constrained.

FAQ
Is PTVS13VS1UR,115 qualified for automotive applications?
Yes - per revision v.4 (December 2025) of the official Nexperia datasheet, PTVS13VS1UR,115 retains AEC-Q101 qualification. This is confirmed in Section 11 ("Test information") and the revision history, which explicitly lists PTVS13VS1UR among the 33 devices maintained under standard automotive qualification status.
What is the maximum clamping voltage under rated surge conditions?
The maximum clamping voltage (VCL) is 21.5 V at 18.6 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform per IEC 61643-321. This value is specified in Table 8 of the datasheet for the PTVS13VS1UR variant and defines the upper voltage limit imposed on protected circuitry during full-rated surge events.
How does the SOD123W package affect thermal performance?
The SOD123W package delivers Rth(j-sp) = 18 K/W to the cathode solder point, enabling efficient heat transfer to the PCB. When mounted on FR4 with standard footprint, its Rth(j-a) = 220 K/W limits continuous power dissipation but supports full 400 W peak pulses due to short duration and low thermal mass - validated in Figure 2 of the datasheet.
Can PTVS13VS1UR,115 replace PTVS13VS1UR without changes?
Yes - the ,115 suffix denotes tape-and-reel packaging per JEDEC standard J-STD-020, with identical electrical, thermal, and mechanical specifications as the base PTVS13VS1UR. No schematic, layout, or firmware changes are required; only handling and assembly processes differ to accommodate reel-fed pick-and-place equipment.
