Product details
Overview
PTVS24VS1UR/8X 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 24 V reverse standoff voltage (VRWM), 29.5 V maximum clamping voltage (VCL) at 10.3 A peak pulse current, and 0.001 µA reverse leakage at VRWM - enabling robust protection of 24 V industrial control and power management circuits against IEC 61643-321 10/1000 µs surges.
For engineers reviewing the PTVS24VS1UR/8X datasheet, PTVS24VS1UR/8X pinout, PTVS24VS1UR/8X application, or PTVS24VS1UR/8X equivalent, this device is selected for precise 24 V rail protection where low-profile mounting, high surge immunity, and verified AEC-Q101 qualification status (per revision v.4, December 2025) are required in industrial and legacy automotive subsystem designs.
Technical Context
This unidirectional TVS operates as a clamping diode with avalanche breakdown behavior, triggered when reverse voltage exceeds its 24 V standoff threshold. Its junction-to-solder-point thermal resistance is 18 K/W, supporting sustained surge dissipation in compact PCB layouts with minimal copper area.
The device complies with IEC 61643-321 for 10/1000 µs waveform testing and delivers 38.9 A rated peak pulse current (IPPM) at 24 V VRWM. Its cathode-anode polarity is marked by a bar on the SOD123W body, aligning with standard PCB layout conventions for unidirectional protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse operating voltage before clamping begins; sets protection threshold for 24 V nominal systems. |
| VCL @ IPPM | 29.5 V at 38.9 A - Clamped voltage during worst-case 10/1000 µs surge; ensures downstream ICs see ≤29.5 V under full-rated stress. |
| PPPM | 400 W - Peak pulse power handling per IEC 61643-321; enables single-device protection against high-energy transients. |
| IRM | 0.001 µA at VRWM - Ultra-low leakage preserves system quiescent current in battery-powered or low-power 24 V sensors. |
| VBR min/max | 26.7 V / 29.5 V - Breakdown voltage range at 1 mA test current; guarantees activation within tight margin above VRWM. |
| Rth(j-sp) | 18 K/W - Junction-to-solder-point thermal resistance; allows direct thermal coupling to PCB copper for reliable surge duty cycling. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode-marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 24 V rail); marking bar identifies this terminal for correct orientation during placement. |
| 2 | Anode (A) | Connected to ground reference; forms clamping path during overvoltage events to shunt surge current to GND. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power rating | Enables single-device protection against high-energy transients per IEC 61643-321 without parallel staging. |
| AEC-Q101 qualified (v.4 revision) | Validated for automotive-grade reliability including temperature cycling, HBM ESD (>4 kV), and mechanical stress tests. |
| 1 mm profile SOD123W package | Reduces board space and height constraints in dense industrial modules and automotive ECUs requiring low-profile components. |
| 0.001 µA reverse leakage at VRWM | Minimizes standby power loss in always-on 24 V monitoring circuits and extends battery life in backup systems. |
Applications
| Industrial Power Rail Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Protecting 24 V supply inputs in PLC I/O modules against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between 24 V rail and chassis ground to limit voltage excursions during ISO 7637-2 Pulse 5a events. Use Value: Maintains rail voltage ≤29.5 V during 38.9 A surges, preventing latch-up or damage to downstream DC-DC controllers and microcontrollers. |
Use Scenario: Safeguarding LIN bus power pins and sensor supply lines in BCMs exposed to battery transients. IC Role / Device Role / Timing Role: Standoff-clamp protection element on 24 V auxiliary rails feeding door lock actuators and interior lighting drivers. Use Value: Provides AEC-Q101-validated surge immunity while occupying <2.6 mm² PCB area - critical for space-constrained BCM stacking. |
| Factory Automation Sensor Interface | Telecom Power Management |
|
Use Scenario: Shielding 24 V fieldbus interfaces (e.g., Profibus PA) from EFT bursts and electrostatic discharge in manufacturing environments. IC Role / Device Role / Timing Role: Primary overvoltage clamp on sensor-side 24 V feed, positioned upstream of filtering and regulation stages. Use Value: Limits ESD-induced voltage overshoot to ≤29.5 V with sub-nanosecond response, preserving signal integrity in analog sensor front-ends. |
Use Scenario: Protecting secondary-side 24 V outputs of telecom AC/DC power supplies against lightning-induced surges on distribution lines. IC Role / Device Role / Timing Role: Final-stage transient suppressor on output rail before connector interface to remote radio units. Use Value: Delivers 400 W surge capacity in minimal footprint, enabling compliance with GR-1089-CORE Level 3 telecom surge requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package (4.5 mm × 2.7 mm × 2.2 mm); 400 W PPPM; VCL = 38.9 V @ 10.3 A; higher profile and larger footprint. | Less suitable for ultra-thin industrial modules or stacked automotive ECUs due to 2.2 mm height and 11.5 mm² area. | Select when board-level thermal mass supports higher Rth(j-a) or when legacy DO-214AC footprint is fixed. |
| SMCJ24A | DO-214AB package (7.1 mm × 6.2 mm × 2.6 mm); 1500 W PPPM; VCL = 38.9 V @ 38.9 A; significantly larger and higher power-rated. | Over-specified for 24 V rail protection where 400 W suffices; introduces unnecessary cost and board area penalty. | Choose only if system-level surge testing requires >400 W margin or multi-event endurance beyond IEC 61643-321 Class II. |
Compared with SMAJ24A and SMCJ24A, PTVS24VS1UR/8X offers identical 24 V standoff and 400 W rating but in a 65% smaller footprint and 55% lower profile - making it optimal for space- and height-constrained 24 V protection where thermal coupling to PCB copper is preferred over ambient convection.

FAQ
Is PTVS24VS1UR/8X qualified for automotive use?
Yes - per revision v.4 (December 2025) of the official Nexperia datasheet, PTVS24VS1UR/8X retains AEC-Q101 qualification for discrete semiconductors, covering temperature cycling, mechanical shock, and ESD testing. This applies to all 33 part numbers listed in the revision history, including PTVS24VS1UR.
What is the maximum clamping voltage under full-rated surge current?
At its rated peak pulse current of 38.9 A (IPPM), PTVS24VS1UR/8X clamps to a maximum of 29.5 V, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the absolute upper voltage seen by protected circuitry.
How does the SOD123W package affect thermal performance?
The SOD123W package achieves a junction-to-solder-point thermal resistance (Rth(j-sp)) of 18 K/W when soldered to a standard cathode pad. This enables efficient heat transfer directly into PCB copper, allowing repeated surge events without thermal runaway - unlike higher-Rth(j-a) packages relying on ambient convection.
Can PTVS24VS1UR/8X replace older PTVS24VS1U parts?
No - PTVS24VS1UR/8X uses the "R" suffix denoting the revised qualification status per v.4 datasheet, while legacy PTVS24VS1U parts lack updated AEC-Q101 documentation and may not meet current revision's thermal or surge test criteria. Cross-reference must be validated using official Nexperia change notices.
