Product details
Overview
PTVS24VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature overvoltage protection in power rails. It features VRWM = 24 V, VBR(min) = 26.7 V, VCL = 38.9 V at IPPM = 10.3 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust surge suppression in industrial power supplies and automotive under-hood modules.
For engineers reviewing the PTVS24VS1UTR datasheet, PTVS24VS1UTR pinout, PTVS24VS1UTR application, or PTVS24VS1UTR equivalent, this device delivers verified clamping performance at elevated junction temperatures, low IRM ≤ 0.001 µA at VRWM, and precise unidirectional polarity with cathode-marked SOD123W footprint compatibility.
Technical Context
This TVS diode uses a planar silicon junction optimized for stable breakdown behavior across −55 °C to +185 °C ambient. Its unidirectional configuration provides forward conduction only during reverse transient events, with clamping initiated at VBR = 26.7–29.5 V and sustained at VCL = 38.9 V under 10.3 A peak pulse current.
The device complies with IEC 61643-321 (10/1000 µs waveform) and supports ESD immunity per IEC 61000-4-2 (30 kV contact discharge). Thermal resistance Rth(j-sp) = 18 K/W enables effective heat transfer via cathode solder point in high-power transient scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 26.7 V - guaranteed minimum breakdown voltage at 1 mA, ensuring predictable turn-on margin |
| VCL @ IPPM | 38.9 V at 10.3 A - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power rating per IEC 61643-321, valid up to 185 °C junction temperature |
| IRM | ≤ 0.001 µA at VRWM - ultra-low leakage preserves efficiency in battery-backed or low-quiescent systems |
| Tj max | 185 °C - extended junction temperature rating enables placement near hot components without derating |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount outline with cathode bar marking |
Pinout & Package
SOD123W (CFP3) package: 2-terminal surface-mount plastic case, 2.6 mm × 1.7 mm × 1.0 mm body height, cathode marked by molded bar on terminal 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's positive rail; absorbs reverse transients when voltage exceeds VBR |
| 2 | Anode (A) | Connected to ground or low-impedance return path; completes clamping current loop during surge events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 185 °C - eliminates thermal derating in engine control units and industrial motor drives |
| Low-profile packaging | 1.0 mm max height - enables use in space-constrained PCB layouts without compromising thermal relief |
| Ultra-low leakage | IRM ≤ 0.001 µA - prevents parasitic drain in always-on power domains and energy-harvesting circuits |
| IEC 61000-4-2 ESD rating | 30 kV contact discharge - exceeds Level 4 immunity requirements for industrial field interfaces |
| Thermal resistance optimization | Rth(j-sp) = 18 K/W - enables direct heat sinking through cathode pad to internal copper layers |
Applications
| Power Supply Protection | Industrial Motor Drives |
|---|---|

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 | Lower PPPM = 400 W but rated only to Tj = 150 °C; VCL = 38.9 V same, but IRM = 1 µA (1000× higher) | Not suitable for >150 °C ambient zones; requires larger thermal margin in enclosed enclosures | Select when cost sensitivity outweighs high-temp requirement and leakage is non-critical |
| SMCJ24A | Same VRWM/VCL but larger DO-214AB package (7.11 × 6.22 × 2.34 mm); PPPM = 1500 W; Rth(j-a) ≈ 15 K/W | Better power handling but incompatible with SOD123W footprint; unsuitable for dense layouts | Select when surge energy exceeds 400 W and board space allows larger package |
Compared with SMAJ24A and SMCJ24A, PTVS24VS1UTR uniquely balances 400 W pulse capability, 185 °C junction rating, and ultra-low leakage in the smallest qualified SMD outline - making it optimal for thermally aggressive, space-constrained 24 V systems where long-term reliability is critical.

FAQ
What is the maximum clamping voltage of PTVS24VS1UTR under standard test conditions?
The clamping voltage VCL is 38.9 V at IPPM = 10.3 A, measured using the 10/1000 µs current waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C), with no derating required up to maximum junction temperature.
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 SOD-123 (≈40 K/W) - due to its optimized cathode tab design and reduced die-to-solder-point distance. This enables efficient heat extraction directly into the PCB copper, supporting sustained 400 W pulse handling in compact layouts.
Can PTVS24VS1UTR be used in bidirectional protection configurations?
No - PTVS24VS1UTR is strictly unidirectional. Its anode-cathode structure conducts only during reverse-biased transients. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., PTVS24VS1UTR's counterpart PTVS24VS1UTR-B) must be selected.
Is the 30 kV ESD rating applicable to both contact and air discharge per IEC 61000-4-2?
The 30 kV rating applies only to contact discharge per IEC 61000-4-2. Air discharge rating is not specified in the datasheet; testing was performed using ten non-repetitive contact discharges. For air discharge requirements, system-level validation is recommended, as layout and grounding dominate final performance.
