Product details
Overview
PTVS10VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features 10 V reverse standoff voltage (VRWM), 17.0 V clamping voltage (VCL) at 23.5 A peak pulse current (IPPM), and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS10VS1UTR datasheet, PTVS10VS1UTR pinout, PTVS10VS1UTR application, or PTVS10VS1UTR equivalent, this device is selected for robust ESD and surge protection in industrial power management where thermal stability and low-profile mounting are critical.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transients above its VRWM of 10 V. Its VBR is specified at 11.1–12.3 V (min–max) with 5 mA test current, and it maintains stable clamping performance across –55 °C to +185 °C ambient range.
It complies with IEC 61643-321 (10/1000 µs waveform) and delivers 400 W peak pulse power at 25 °C, derating to ~220 W at 150 °C per typical curve. Reverse leakage is limited to 0.005 µA at VRWM, supporting low-power standby integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VCL @ IPPM | 17.0 V at 23.5 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321, enabling robust surge immunity |
| IRM | 0.005 µA - ultra-low reverse leakage preserves efficiency in always-on power rails |
| Tj max | 185 °C - extended junction temperature rating supports operation in hot industrial enclosures |
| Rth(j-sp) | 18 K/W - low thermal resistance from junction to solder point enables effective PCB heat dissipation |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - protects against human-body and system-level ESD events |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat lead profile optimized for automated assembly and thermal relief on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., VBUS); marking bar identifies this terminal |
| 2 (A) | Anode | Connected to ground reference; forms unidirectional clamping path to GND |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates derating concerns in engine control, motor drives, and enclosed industrial systems |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained modules and stacked PCB assemblies |
| Stable clamping under thermal stress | VCL drift < ±5 % from 25 °C to 150 °C - ensures consistent protection margin across operating range |
| High ESD immunity | 30 kV contact discharge - exceeds IEC 61000-4-2 Level 4, reducing need for secondary protection |
| Low IRM at VRWM | 0.005 µA - minimizes quiescent current loss in battery-backed or energy-harvesting circuits |
Applications
| Industrial Power Supply Protection | Automated Test Equipment (ATE) Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC package (3.5 mm height), 400 W PPPM, VRWM = 10 V, VCL = 16.0 V @ 24.9 A | Larger footprint and higher profile - less suitable for ultra-thin industrial modules | Preferred when higher surge current margin is needed and board height allows DO-214AC |
| 1.5SMC10A | DO-214AB package (2.7 mm height), 1500 W PPPM, VRWM = 10 V, VCL = 17.0 V @ 88.2 A | Higher power rating but significantly larger size and lower thermal density - requires more PCB area and heatsinking | Chosen for high-energy surge environments (e.g., outdoor telecom) where SOD123W's 400 W is insufficient |
Compared with SMAJ10A and 1.5SMC10A, PTVS10VS1UTR offers superior thermal density (18 K/W Rth(j-sp)) and minimal 1.0 mm profile-critical for compact, high-temperature industrial designs where space and thermal management are constrained.

FAQ
What is the maximum clamping voltage of PTVS10VS1UTR under a 10/1000 µs surge?
The clamping voltage (VCL) is 17.0 V at 23.5 A peak pulse current (IPPM), measured per IEC 61643-321. This value is guaranteed across the full operating temperature range and defines the maximum voltage seen by downstream circuitry during a standardized surge event.
Can PTVS10VS1UTR be used in bidirectional protection configurations?
No - PTVS10VS1UTR is a unidirectional TVS diode with cathode/anode polarity. It conducts only during reverse-biased overvoltage events. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional part like PTVS10VS1UTR-B should be selected.
How does the 185 °C junction rating translate to real-world PCB layout?
The 185 °C Tj rating means the die can safely operate at that temperature. To achieve this, the PCB must provide adequate thermal conduction - typically via ≥1 cm² copper pour on the cathode pad (Rth(j-sp) = 18 K/W). Standard FR4 footprints yield ~70 K/W Rth(j-a), limiting sustained power dissipation unless heatsinking is added.
Is PTVS10VS1UTR automotive-qualified?
No - this device is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-critical automotive systems. It may be used in non-safety automotive subsystems only after full customer validation and risk assessment.
