Product details
Overview
PTVS24VS1UR,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 VRWM = 24 V, VBR(min) = 26.7 V, VCL(max) = 38.9 V at IPPM = 10.3 A (10/1000 µs), and IRM ≤ 0.1 µA - deployed in industrial power supply protection circuits where space-constrained board layout and fast response to ESD/EFT events are critical.
For engineers reviewing the PTVS24VS1UR,115 datasheet, PTVS24VS1UR,115 pinout, PTVS24VS1UR,115 application, or PTVS24VS1UR,115 equivalent, this device is selected for its 1 mm profile, AEC-Q101 qualification status (per revision history v.4), low leakage, and precise 24 V standoff voltage - key for 24 V automotive and industrial control rail protection where clamping margin and thermal reliability under repetitive surges must be verified.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche diode, triggering when transient voltage exceeds its breakdown threshold (VBR = 26.7–29.5 V). Its IEC 61643-321-compliant 10/1000 µs pulse handling (PPPM = 400 W) enables robust suppression of surge events without latch-up or degradation under repeated stress.
Thermal performance is defined by Rth(j-sp) = 18 K/W (to solder point) and Rth(j-a) = 70 K/W (on ceramic PCB), supporting operation up to Tj = 150 °C. The cathode-marked SOD123W package ensures correct polarity placement during automated assembly and maintains low inductance for high-frequency transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - maximum continuous reverse operating voltage before clamping begins; matches standard 24 V DC supply rails. |
| VBR (min) | 26.7 V - guaranteed minimum breakdown voltage at IR = 1 mA; defines earliest conduction onset during overvoltage. |
| VCL (max) | 38.9 V - maximum clamped voltage at IPPM = 10.3 A (10/1000 µs); limits downstream IC stress during surge. |
| PPPM | 400 W - peak pulse power rating per IEC 61643-321; supports high-energy transients without failure. |
| IRM | ≤ 0.1 µA - reverse leakage at VRWM; ensures negligible standby current drain in battery-backed systems. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount package with cathode marking bar; optimized for high-density PCB layouts. |
| ESD Rating | 30 kV (IEC 61000-4-2 contact discharge); provides system-level ESD immunity without external shielding. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, 1 mm height, cathode indicated by marking bar. Dimensions: 2.6 mm × 1.7 mm × 1.0 mm body; recommended reflow footprint per Nexperia doc sod123w_fr.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 24 V rail); absorbs surge current into ground path when clamping. |
| 2 | Anode (A) | Connected to circuit ground; completes low-inductance return path for transient current during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors - validated for automotive-grade reliability (per revision history v.4). |
| Low-profile SOD123W | 1.0 mm max height enables use in ultra-thin modules and stacked PCB assemblies where Z-axis clearance is constrained. |
| 400 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (2 kV line-to-ground) on 24 V systems without derating or parallel devices. |
| 0.1 µA max reverse leakage | Minimizes quiescent power loss in always-on 24 V monitoring circuits (e.g., CAN node power rails, sensor interfaces). |
| Cathode-marked polarity | Visible bar on package top eliminates orientation errors during pick-and-place and visual inspection. |
Applications
| Industrial Power Supply Protection | 24 V PLC I/O Module Protection |
|---|---|
Use Scenario: Protecting 24 V DC input stage of programmable logic controller (PLC) power supplies against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 24 V rail and ground; clamps transients within nanoseconds to prevent damage to upstream rectifiers and downstream DC/DC converters. Use Value: Maintains system uptime by preventing catastrophic failure during field-deployed operation in factory automation environments with high EMI exposure. |
Use Scenario: Safeguarding digital input/output channels on 24 V-rated PLC modules exposed to relay coil flyback and cable ESD events. IC Role / Device Role / Timing Role: TVS mounted adjacent to terminal block; suppresses fast-rising transients (<1 ns rise time) before they reach isolation barriers or microcontroller GPIOs. Use Value: Eliminates need for additional RC snubbers or optocoupler derating, reducing BOM count and board area while meeting IEC 61000-4-4/5 compliance. |
| Automotive Body Control Module (BCM) | Industrial Motor Drive DC Bus Protection |
Use Scenario: Protecting 24 V auxiliary power distribution in commercial vehicle BCMs against battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main 24 V feed; coordinated with fuse and upstream MOSFET switch to limit energy dissipation. Use Value: Enables single-device protection architecture compliant with ISO 7637-2 Pulse 1/2a/5a, reducing design complexity versus multi-stage solutions. |
Use Scenario: Clamping voltage spikes on 24 V DC bus of compact brushless DC motor drives during PWM commutation and brake regeneration. IC Role / Device Role / Timing Role: Parallel-connected TVS across bus capacitor; absorbs regenerative energy spikes that exceed capacitor ripple rating. Use Value: Prevents premature electrolytic capacitor degradation and extends drive lifetime in HVAC and material handling equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package (4.5 mm height); PPPM = 400 W; VBR = 26.7–29.5 V; VCL = 38.9 V; IRM = 0.1 µA - identical electrical specs but larger footprint and higher profile. | Not suitable for ultra-low-profile designs; requires more PCB area and may conflict with nearby tall components. | Select SMAJ24A only if legacy DO-214AC footprint compatibility or higher thermal mass is required. |
| SMCJ24A | DO-214AB package (2.6 mm height); PPPM = 1500 W; VBR = 26.7–29.5 V; VCL = 38.9 V; IRM = 0.1 µA - same clamping but 3.75× higher pulse power rating. | Over-specified for most 24 V industrial applications; introduces unnecessary cost and board space usage. | Choose SMCJ24A only when protecting against extreme surges (e.g., outdoor telecom power inputs) exceeding IEC 61000-4-5 Level 5. |
Compared with SMAJ24A and SMCJ24A, PTVS24VS1UR,115 delivers identical clamping performance in a 62% smaller footprint and 89% lower profile - making it optimal for space-constrained 24 V embedded systems where thermal management relies on solder-point conduction rather than ambient convection.

FAQ
Is PTVS24VS1UR,115 qualified for automotive applications?
Yes - per revision history v.4 (2025-12-01), PTVS24VS1UR,115 is explicitly listed among the 33 types granted AEC-Q101 qualification. This qualification covers stress testing per Automotive Electronics Council standards for discrete semiconductors, including temperature cycling, humidity bias, and ESD robustness, confirming suitability for under-hood and chassis-mounted automotive modules.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage (VCL) for PTVS24VS1UR,115 is 38.9 V at IPPM = 10.3 A under the standardized 10/1000 µs current waveform per IEC 61643-321. This value is measured at Tj = 25 °C and guarantees that downstream 24 V-rated ICs experience no more than 38.9 V during worst-case surge events.
How does the SOD123W package affect thermal performance?
The SOD123W package achieves Rth(j-sp) = 18 K/W to the cathode solder point, enabling efficient heat transfer into the PCB copper pour. Unlike larger packages, its low 1 mm height minimizes thermal resistance to the board but requires adequate cathode pad area (≥1 cm² tin-plated copper) to sustain 400 W pulses without junction overheating beyond 150 °C.
Can PTVS24VS1UR,115 replace PTVS24VS1UR without changes?
Yes - PTVS24VS1UR,115 and PTVS24VS1UR share identical electrical specifications, SOD123W package dimensions, pinout, and marking (AN). The ",115" suffix denotes tape-and-reel packaging per JEDEC standard J-STD-020, with no functional or parametric difference; it is a direct replacement for automated assembly lines requiring standard reel logistics.
